Companies could be charged to hire skilled workers from the European Union after Brexit, Immigration Minister Robert Goodwill has suggested.

A £1,000 immigration "skills charge" is being brought in this April for firms recruiting workers from outside the EU.
Mr Goodwill told peers a similar levy for EU workers "may be something that has been suggested to us could apply".
One business group said the idea had "raised eyebrows" while a top European politician said it was "shocking".
But Downing Street said Mr Goodwill's remarks had been "misinterpreted" and such a levy was "not on the government's agenda".
The government says the decision to leave the EU will give the UK greater control over its borders but British firms are concerned about their capacity to fill vacancies, particularly for low-paid seasonal work, if there are limits on migration from the EU.
Appearing before the Lords EU home affairs sub-committee, Mr Goodwill referred to an annual £1,000 charge on businesses for every skilled worker they employ from outside Europe, which will take effect in two months time.
The levy, which applies to workers in "skilled areas" but with exemptions for PhD-level posts, is designed to reduce firms' reliance on migrant labour and encourage them to train more local workers.
"That's something that currently applies to non-EU," the MP said. "That may be something that's been suggested to us that could apply to EU."
Home Affairs Correspondent Danny Shaw said Mr Goodwill had raised the question of the charge himself rather than in response to questioning from MPs, suggesting he wanted to "float the idea".
Mr Goodwill also suggested a seasonal scheme to enable agricultural workers, such as fruit pickers, to come to Britain for short periods was a possibility, telling MPs "that's certainly one of the options that could be open to us post-Brexit".
The National Farmers Union supported such an idea for workers from outside the EU, he added.
About 60,000 seasonal workers come to the UK each summer, mainly from eastern Europe, and ministers have said British farmers must continue to have access to a supply of labour after the UK's exit.
Between 2007 and 2014, UK firms were allowed to employ a certain number of fruit pickers from Bulgaria and Romania for a six-month period but this scheme expired when transitional work restrictions on the two countries following their entry to the EU were lifted.
The government has said it remains committed to reducing annual net migration to less than 100,000 a year although it has consistently failed to meet the target, with the figure remaining above 300,000 for the past 18 months.
In the year to June 2016, a record number of EU citizens - 284,000 - came to live in Britain.
Many Conservative MPs want a level playing field for EU and non-EU workers, believing Brexit is an opportunity to end the preferential treatment EU workers currently receive in the immigration system.
But former business minister Anna Soubry - who backs the UK staying in the EU's single market - said a levy would be a "tax on successful businesses".
"Discouraging EU nationals from coming to Britain would harm our economy, deterring investment and hitting our public finances," she said.
Former Belgian prime minister Guy Verhofstadt, who is leading the European Parliament's Brexit team and is a strong supporter of the continued right to free movement across Europe, tweeted: "Imagine, just for a moment, what the UK headlines would be, if the EU proposed this for UK nationals? Shocking."
The Federation of Small Businesses said it had been assured by the Home Office that Mr Goodwill was only referring to the imminent levy on non-EU workers.
A spokesman added: "The priority for small businesses is to make sure that current EU nationals in the UK workforce are given the right to remain."


West Ham beat Crystal Palace to climb out of the relegation zone as Christian Benteke missed a penalty for the hosts.

Manuel Lanzini converted Aaron Cresswell's low cross to secure the Hammers' first win in six Premier League games in an uninspiring match at Selhurst Park.
Benteke missed two chances to level for Palace, floating a woeful spot-kick wide after he was fouled by Angelo Ogbonna and heading against the post moments later.
West Ham, who started the game in the bottom three but are now up to 15th, were reduced to 10 men for the last 15 minutes when Cresswell received two bookings within the space of 51 seconds.
Hammers keeper Adrian had to make a point-blank save from Connor Wickham's header in injury time, but Alan Pardew's eighth-placed Palace were generally lacking in attack as their five-game unbeaten run in the league came to an end.

It was a timely result for West Ham boss Slaven Bilic, whose only other league win this season had come against Bournemouth in August.
After leading West Ham to a seventh-placed finish last season, Bilic had overseen the Hammers' worst start to a top-flight campaign since 1988-89 in the first seven games this term.
But this solid, if not exhilarating, win will ease fears of a relegation battle for a club that has moved into the London Stadium, which currently has a 57,000-capacity.
The Croat reshaped his side from the 1-1 draw against Middlesbrough two weeks ago, playing with three centre-backs and bringing left wing-back Cresswell back into the team for the first time this season after a knee injury.
And it was Cresswell, who has been touted as a possible England international, who provided the tantalising ball from the left that Lanzini side-footed past Steve Mandanda for his eighth West Ham goal.
The Hammers almost finished the game off before Cresswell's dismissal, but Jason Puncheon was on hand to clear Michail Antonio's header off the line.
Instead, West Ham had to hold on to their lead with a one-man disadvantage after a harsh sending off for Cresswell.
His first booking, moments after the Antonio chance, was given for a dive in the area, although there looked to be some contact from Yohan Cabaye's challenge.
And less than a minute later he was shown another questionable yellow card for putting an arm across Wilfried Zaha when the pair were chasing a ball down the Palace right flank.
Palace, who had improved in the second half, immediately saw more of the ball and pinned back the visitors, but only produced the late chance for substitute Wickham.
For Crystal Palace, it was a performance uncharacteristic of their season so far, having won four of their first seven league games and soaring into the top half of the table.
And even though they failed to register a shot on target until the 57th minute, the Eagles could have won the game had Benteke not been so wasteful.
The Belgian has three goals already this season and scored a hat-trick for his country against Gibraltar on Monday, but his wayward penalty, alongside a pair of headed chances - one that hit the post and another that went over from close range - could have salvaged something for Palace from an uninspiring display.
The result continues Palace's recent struggles against West Ham, having won just one of their past five top-flight meetings with their London rivals.
West Ham manager Slaven Bilic told BBC Sport: "We opened them up really well and created chances. We produced a really good performance.
"The second yellow card was an extremely, extremely harsh decision. Those two decisions were not correct. I don't like to moan. I'm the first to say it's very hard for referees... but those two decisions today... thank God it didn't affect the result.
"It was by far Simone Zaza's best performance today. He won more balls in the air than in the previous games. I hope we have turned the corner. We need to repeat this. We have to have this kind of approach. It's a cruel league but I never stop believing."

Crystal Palace manager Alan Pardew told BBC Sport: "I was disappointed with a lot of aspects of the game.
"We didn't start well and they got a deserved lead. We had to make changes at half-time because weren't playing with the fluidity as we have done. We were better in the second half.
"We should have at least got a draw. With the penalty I was thinking with the week Benteke has had it'll go in.
"That would have been a lifeline and would have turned the game on its head. We would gave gone in 1-1 at half-time. This happens in the course of the season. Adrian made a good save at the end."

A 38-year-old man has died after being found seriously injured at a house in Inverclyde.

Terence McGeown was found at the property in Broadstone Avenue in Port Glasgow at about 06:30 on Saturday.
He was taken to Inverclyde Royal Hospital but died later of his injuries.
Police said a 24-year-old man had been arrested and detained in connection with the death. He is due to appear at Greenock Sheriff Court on Monday.


Our internal body clock has such a dramatic impact on sporting ability that it could alter the chances of Olympic gold, say researchers.

The team at the University of Birmingham showed performance times varied by 26% throughout the day.
Early risers reached their athletic peak around lunchtime, while night owls were best in the evening.
The researchers say it could even explain why Spanish teams have more success in European football.
The body clock controls everything - from alertness to the risk of a heart attack - in a daily rhythm.
Some aspects of sporting ability were thought to peak in early afternoon but a study in the journal Current Biology suggests each competitor's sleeping habits have a powerful impact.
They took 20 female hockey players and asked them to perform a series of 20m runs in shorter and shorter times.
And they did it at six different times of day between 07:00 and 22:00.
The results showed a peak performance in late afternoon, but then the scientists looked separately at early-type people, late-type people and those in the middle.
This time the gap between the best and worst times was 26%, and a far more complicated picture emerged.
Lead researcher Dr Roland Brandstaetter told the BBC News website: "Athletes and coaches would benefit greatly if they knew when optimal or suboptimal performance time was."
He said a 1% difference in performance would be the difference between fourth place and a medal in many Olympic events.
Body clocks can be adjusted. Jet lag is when you feel rough before adjusting to a new time.
"So if you're an early type in a competition in the evening, then you're impaired, so you could adjust sleeping times to the competition," Dr Brandstaetter said.
He said such body-clock problems "absolutely" contributed to England's struggles in the pinnacle of European football - the Champions League.
"You have players that do extraordinarily well in the English Premier League at 15:00, but they suddenly don't perform as well in the evening in the Champions League," he said.
He argued Spanish society, which runs a bit later in the day, may be giving teams from that country an advantage.
Emily Defroand, a 20-year-old who has been capped 56 caps with Team GB's Hockey U21s, took part in the study and said the findings were "scarily realistic".
She is an early riser, that rare student happy to get up at 07:30 in the morning.
She said: "Our Saturday matches are at 12:30, and I think that's perfect for me. Any later and I feel a bit tired and need a few more energy drinks to get me going."
It is in stark contrast to her team-mate Olivia Chilton.
She said: 'I'd get up at 11:00 if I could get away with it. I much prefer training late afternoon or evening.
"In the morning, I honestly feel half-asleep in the warm-up, I just don't feel alert, for tracking and hitting the ball, I don't feel on it."
Dr Brandstaetter said this provided an important lesson for talent-spotting.
"It takes place more or less in adolescents, but we know half of them are owls, yet almost all cases of talent-spotting are during the school hours," he said.
"That is when they are in the range of 70-80% of peak performance, so we are missing out on a huge number of high performers by testing at the wrong time of day."
Commenting on the findings, Dr Thomas Kantermann, from the University of Groningen and the scientific manager of the ChronoCity project in Germany, told the BBC: "The study adds to our understanding about the importance of circadian biology [body clocks] and internal time in physical performance.
"Only by taking internal time into account can true and fair assessments of human performance become possible.
"The current paper supports our previous research and nicely paves the way for more fruitful circadian studies in the future."


A private detective hired through a crowdfunding appeal has said a missing airman's mobile phone is "key" to the investigation.

Corrie Mckeague, 23, vanished after a night out in Bury St Edmunds, Suffolk, on 24 September.
Experts from McKenzie Intelligence Services were brought in to assist Suffolk Police after Â£51,000 was raised through an online crowdfunding page.
Forbes McKenzie said his team would add "clarity" to the investigation.
What do we know about Corrie Mckeague's disappearance?
He said: "Our mission is to create clarity from the huge amount of data that has emerged.
"We think the phone is a key piece of information.
"Where the phone finished is indicative of where Corrie was last.
"I'm very interested in what other phones were co-located with Corrie's phone."
Mr McKenzie, whose company is based in London, said he had three specialists, including himself, working on the case.
He stressed his team was "not running a parallel investigation" to Suffolk Police but was there to "add value" to what the force was doing.
The team's first task would be to collate all of the information available on social media feeds, CCTV and areas that have and have not been searched, he said.
"We are plugging the gaps that Suffolk Police just doesn't have the people power to do.
"This investigation might prove to be the very first crowdfunded and crowd-data sourced investigation," Mr McKenzie added.
About 5,000 people pledged support to the crowdfunding page after the family of Mr Mckeague, from Dunfermline, Fife, expressed concerns about the police investigation.
The RAF Honington gunner was last seen at about 03:25 BST walking alone in the Suffolk town.
A second public search for Mr Mckeague will take place on 22 January. More than 60 volunteers joined in the first on 17 December.


Award-winning TV writer and comedian Caroline Aherne is recovering from treatment for lung cancer.

Macmillan Cancer Support confirmed that the Royle Family star, who has previously had bladder and eye cancer, would speak at an appeal to improve cancer care in Manchester on 26 June.
Aherne, 50, said of the appeal: "I've had cancer and my brother's had cancer and we know how it affects people."
She has starred in The Mrs Merton Show, The Royle Family and The Fast Show.
Nicola Cook, from Macmillan Cancer Support, said: "Caroline's one of Manchester's own - she's loved here and people identify with her. We hope that if people see that Caroline is sitting down and talking to us then maybe they'll know that they can too."
Aherne had eye cancer along with her brother when she was a child and also revealed that she had been treated for bladder cancer in the past.
Her brother Patrick told Macmillan Cancer Research that his sister was diagnosed "late last year" and that "the form of lung cancer that she is suffering from is genetic and linked to the retinoblastoma she had as a baby".
"Her bladder cancer was also genetic and linked to the retinoblastoma," he said, adding that she no longer smokes and is keen to raise awareness about the Macmillan cause rather than her medical condition.
Aherne said: "They've asked me to get involved and I'm really glad that I can do my bit to encourage Manchester people to speak up about where things do go wrong with cancer care."
The writer and actress said it was "truly shocking" that the city had come bottom of 150 areas in England for premature deaths from cancer.
"Our survival rates are 25% lower than average and the number of people getting lung cancer is a third higher here than in the rest of England," she said.
She added that her role on Channel 4 series Gogglebox would not be affected, and said: "I will be narrating this week's Gogglebox, and I will continue to narrate Gogglebox for as long as Gogglebox want me."
Aherne, who was born in London but lived in Manchester from the age of two, began her career as gossiping granny Mrs Merton.
Mrs Merton got her own TV chat show in 1995 and her no-holds-barred interviewing style ensured it became a hit.
The show won a Bafta in 1997 for best talk show and a BBC Comedy Award for top BBC One personality.
She was also one of the writers and performers on BBC Two's sketch series The Fast Show, which screened from 1994 to 2001.
With Craig Cash, she went on to write BBC Two's acclaimed comedy The Royle Family, which revolved around a family who spent most of their time slumped in front of the TV.
Aherne and Cash also starred in the series along with Sue Johnston, Ricky Tomlinson, Liz Smith, Ralf Little and Jessica Hynes.
It ran from 1998 to 2000 and had a one-off return in 2006, in which the comedy was mixed with sadness when Nana died.
The Royle Family won two Baftas in 2000 and another in 2007 for best situation comedy.
Aherne's sometimes troubled personal life often featured in the tabloid press. She split from her first husband, New Order bass player Peter Hook, in 1996.
She was then involved in a relationship with television researcher Matt Bowers, who was caught on camera fighting with Hook at a party in Manchester.
Aherne split with Mr Bowers, who died from stomach cancer in 1997.
A suspected suicide bid in 1998 brought into sharp focus the problems she was having. Following a drug overdose, Aherne admitted she was an alcoholic and had not been aware of what she was doing to herself.
She moved to Australia to escape media scrutiny and within a year had written and produced Dossa and Joe - a sitcom about an Australian couple who do not do very much. She returned to the UK in 2002.

Thomson regained the lead in the round-the-world race north of the Kerguelen Islands in the Indian Ocean on 30 November, but then lost ground.
He broke two race records prior to being overtaken, as he reached the Cape of Good Hope in record time.
The Vendee Globe takes place every four years.
Since the first race in 1989, only 71 of 138 starters have completed the voyage, which is known for being one of the most gruelling sporting challenges in the world.

The National League is "very concerned" about the Football League's proposed shake-up, says chairman Brian Barwick.

The Football League wants to create an extra division with 20 teams in each from 2019-20, increasing the number of clubs from 92 to 100.
Both the Football Association and Premier League back the proposal "in principle".
"The National League is very concerned about the potential consequences of any potential adoption," said Barwick.
"We strongly feel its attempt to re-shape the existing professional game structure has failed to take into consideration the effects of any change on football played below its proposed five divisions.
"We seriously believe it could be very damaging to the National League and its member clubs and will be determined to make that point very clear when we meet up with Football League officials to discuss their proposals.
"The National League is an ambitious and forward-thinking organisation as well as a well-established and well-loved competition and we will do everything possible to protect both its integrity and its commercial value."
BBC Sport has contacted the 18 clubs that were neither promoted nor relegated from the top-tier of English non-league football this season about the idea, with the responses ranging from "simply awful" to "long overdue".
However, many of the clubs want to know more before making a decision.
Here are the responses:
Aldershot: Yet to respond.
Barrow: "Simply awful. This is clearly the proposal of someone completely out of touch with grassroots English football and in thrall of the elite clubs. A reduction of potential revenue through less games, a further diminution of the FA Cup to a midweek competition, and absolutely no perceived benefit to any club below the top half of the Championship. I had to check it wasn't 1 April,", said chairman Paul Casson.
Braintree Town: "It introduces another tier between the Premier League and non-league football, effectively relegating all but the eight clubs that are invited to join the re-organised Football League. A better structure would be a reorganised Football League with the existing Championship and League One tiers fed by a League Two North and League Two South," said chairman Lee Harding.
Boreham Wood: No-one available for comment.
Bromley: Yet to respond.
Chester: "Until it is clear how the change in the structure of the Football League will impact upon the ability to generate revenue, i.e. reduced number of home games, potential lack of FA Cup replay revenue, introduction of Premier League B teams, it is not possible to make a decision one way or the other," said chairman Simon Olorenshaw.
Dover Athletic: "It needs careful consideration. We foresee some issues but the devil will be in the detail," said chairman Jim Parmenter.
Eastleigh: No-one available for comment.
Forest Green: "The proposal sounds like a good idea - 20 teams per league, ending Tuesday night games. It makes perfect sense that the top eight teams from our league should be incorporated into the Football League if this goes ahead. In fact, given that below the National League all competitions become regional, the Football League should really think about adopting the National League now. They should also standardise the number of teams that are promoted and relegated between divisions," said chairman Dale Vince.
Gateshead: "Every National League club aspires to be in the Football League, and secondly, football needs to change and it's a good time for us. Everybody needs to understand the detail a bit more, but in principle it's a good idea," said chairman Richard Bennett.
Guiseley: "We need a lot more information about the involvement of Scottish or Premier League clubs in the proposals," said chairman Phil Rogerson.
Lincoln: "From our perspective, we feel it's a positive move by the Football League and is an exciting opportunity for clubs at our level," said manager Danny Cowley.
Macclesfield: Yet to respond.
Southport: "There's been no consultation with the National League board from the Football League. There's a lack of understanding of how the pyramid system will change - what happens to the others when the eight clubs go up?," said a club spokesperson.
Tranmere: No comment to make at this time.
Torquay United: "I believe the lower leagues should be regionalised. Travelling the length of the country, like to Gateshead in front of paltry crowds is farcical," said chairman Dave Phillips.
Woking: "I personally think it is a fantastic proposal and long overdue, I am definitely in favour. The National League standards have been improving year on year, one only has to ask the relegated clubs from League Two how difficult it is to get back where they came from. Furthermore there is, in my opinion, little difference between the two leagues," said Woking football director Geoff Chapple.
Wrexham: No-one available for comment.


Prison officers confiscated about 225kg (496lbs) of drugs in one year, according to the Ministry of Justice.

In 2016 20,000 mobile phones and sim cards, which are also contraband, were also seized from prisoners.
The haul comes after Â£2 million investment in mobile phone detectors across the service, as well as 300 specialist dogs for drug detection.
Prisons minister Sam Gyimah said that the amount of drugs and phones in prisons is "unacceptable".
He said: "I have been clear that the current levels of violence, drugs and mobile phones in our prisons is unacceptable.
"These figures highlight the determination of prison staff to disrupt this behaviour."
Illegal mobile phones are used by some prisoners to continue their criminal activity, and can be rented for up to Â£1,000.
A spokesman for the Ministry of Justice added that the Prisons Service was working to curb the use of drones in delivering phones and drugs, by creating "a specialist squad of prison and police officers".
So far 35 people have been arrested and 11 others have been convicted for drone-related activities.
Mr Gyimah added: "The issues within our prisons will not be resolved overnight, but we must make progress in tackling these problems."
In February, a reporter from BBC's Panorama programme went undercover at HMP Northumberland, where he found a number of inmates incapacitated from taking the drug spice.
In 2016, more than 45% of prisoners in a survey conducted by the HM Inspectorate of Prisons said it was easy to get drugs behind cars.
Mr Gyimah said that the ministry was continuing to employ more prison officers in England and Wales to help tackle the problem. It is hoped there will be an extra 2,500 members of staff by 2018.
The department began rolling out tests for psychoactive substances at prisons in September 2016, in a bid to curb the drugs problem across correctional facilities in England and Wales.
It is also working with mobile network operators to develop ways of blocking mobile phone signals in prisons.

Northamptonshire swept to a convincing double over Glamorgan, winning by 318 runs as the visitors were spun out for just 132 on the third day.

It was the turn of left-arm spinner Graeme White to play the leading role with a career-best 6-44, as fielders clustered round the bat all day.
Off-spinner Rob Keogh took 4-73 to finish with 13 wickets in the match.
Nick Selman top-scored for Glamorgan with 30 not out but the game was over before tea on day three.
A target of 451 was always highly improbable on a pitch that had turned from day one, and Northants claimed wickets at regular intervals.
Four fell by lunch as Glamorgan were unable to break free of the Northants' spinners stranglehold, with Keogh and White taking all 20 in the match compared to 11 from Glamorgan's slow bowlers.
Victory gave Northants the double over Glamorgan after winning by 251 runs in Swansea in August.
Batsman Ben Duckett, who scored 265 runs in the match, and all-rounder Rory Kleinveldt were both awarded their county caps.
Northants spinner Graeme White told BBC Radio Northampton:
"There's been quite a bit of help for the spinners but to wrap the game up like we have done and to have the complete performance with bat and ball is very pleasing, it couldn't have gone any better for us.
"As a spinner you can't always get a run in the team, but it's nice to come across a pitch that does offer a bit of spin for the first time this year, and Rob (Keogh) was bowling really well at the other end.
"It's been a good season (for me), my white-ball cricket is my strength and I've gone well in that so I think at the end of the season I'll be quite pleased with what I've done.
"We want to finish strongly in the Championship, people just think we can play white-ball cricket but that's not the case, this shows we can compete in the format so why not push for promotion next year."
Glamorgan assistant coach David Harrison told BBC Wales Sport:
"We came into the day with hopes of at least batting the day out, build a couple of partnerships and put them under pressure but unfortunately it didn't work out that way.
"Nick Selman played nicely there on a pitch that was difficult when you went in, when you spent a bit of time there it seemed easier but we kept losing wickets and couldn't get that partnership to give us a bit of space.
"Ben Duckett played really well on that pitch and when you've got a big total on the board (against you), scoreboard pressure is always a hard thing.
"It's not a pitch we come across that often on the county circuit, turning that much, so we'll regroup and prepare for the next game against Gloucestershire."


A house in north Belfast has been gutted in an arson attack.

The incident at Alliance Parade was reported shortly before 04:00 BST on Saturday.
Police said it is "believed that someone broke into the house and deliberately set it on fire".
They said there was no-one in the house at the time.


South Africa fast bowler Dale Steyn is out of the Test series in Australia after fracturing his shoulder on day two of the first Test in Perth.

The 33-year-old, who is second in the ICC Test bowling rankings, pulled up while bowling shortly before lunch.
Steyn will return to South Africa to see a shoulder specialist and it is expected he will have surgery.
South Africa closed day two at the Waca on 104-2 in their second innings, leading by 102.
Proteas team manager Dr Mohammed Moosajee said: "An injury of this nature is rare and will in all likelihood require surgery but that will only be confirmed once we receive an opinion from the specialist."
South Africa say he will bat in their second innings "if absolutely necessary". A decision on whether a replacement will be called up has yet to be made.
Steyn's injury marred what was otherwise a superb day for the tourists, who fought back brilliantly after Australia reached 158-0 in reply to South Africa's first-innings' 242.
Before his injury, Steyn took the first wicket to fall, Australia opener David Warner, who top-scored with 97.
Seamer Vernon Philander took 4-56 and debutant left-arm spinner Keshav Maharaj 3-56 as Australia's 10 wickets fell for 86 runs in 35 overs.


The European Tour is set to trial a new six-hole competition featuring a shot clock, music and fewer clubs in an effort to attract younger players.

Tour chief executive Keith Pelley says he hopes to "experiment as early as 2017 and maybe roll it out in 2018".
Speaking on BBC Radio 5 live, he added: "Yes, there'd be a shot clock. Yes, there'd be music and players would probably be dressed a bit differently.
"Maybe they'd only play with five or seven clubs."
Pelley said the format would probably feature the top players representing national sides.
"It would probably be a country competition," he said. "So you could see England playing Scotland in a six-hole matchplay.
"If you're not prepared to change, you're not prepared to be innovative, if you're not prepared to actually take chances, then sports will fall behind."

Syrian President Bashar al-Assad has said Russia has never talked to him about leaving power.

"They never said a single word regarding this," Mr Assad told NBC News, referring to conversations with President Vladimir Putin and officials.
He said "only the Syrian people" would decide "when to come and when to go".
The US, which accuses Syria's leader of responsibility for atrocities, says he must go as part of a political transition to end the conflict there.
Russia has given the Syrian government strong diplomatic and military backing in its fight against rebels, but Mr Putin has said only a political solution can resolve the conflict.
Mr Assad's comments came as US Secretary of State John Kerry prepared to fly to Moscow for fresh talks about Syria.
The Syrian leader said he was not concerned about the possibility of Washington and Moscow agreeing a deal that would involve him stepping down.
"Because their politics, I mean, the Russian politics, is not based on making deals. It's based on values," Mr Assad said.
He said it "won't take more than a few months" until he regained full control of Syria.
He said "terrorism" in Syria had been pushed back "only when the Russians intervened" while the US was "not serious" about tackling so-called Islamic State.
"We wanted to defeat those terrorists, while the United States wanted to manage those groups in order to topple the government in Syria," he said.
In other comments, Mr Assad said Sunday Times reporter Marie Colvin had been "responsible" for her own death, when covering the conflict in 2012.
"It's a war and she came illegally to Syria. She worked with the terrorists, and because she came illegally, she's been responsible of everything that befall on her," he said.
Colvin's family recently said they were suing the Syrian government in the US for wrongful death.
Relatives said they had evidence that she was murdered as part of a policy of deliberately killing journalists.
Colvin was reporting from the rebel-held area of Baba Amr, in Homs, when she was killed by government artillery.
Shortly beforehand, she had done live broadcasts for the BBC, Channel 4 and CNN.


A 25-year-old man has been arrested in connection with the death of a woman in Portavogie, County Down.

Bolivia and the US have agreed to restore full diplomatic ties three years after the US ambassador to La Paz was expelled by President Evo Morales.

In an agreement signed in Washington, the two nations pledged to work together to fight drug trafficking.
President Morales expelled US drug enforcement agents and the ambassador, Philip Goldberg, in 2008, accusing them of conspiring against the government.
But relations have improved and talks began last year to reinstate ties.
The agreement sees "the swift return of ambassadors to Washington and La Paz," according to a Bolivian Foreign Ministry statement cited by Reuters news agency.
"The accord's objectives include strengthening and deepening bilateral relations... (and) supporting efficient co-operation against the production and trafficking of illegal drugs," the statement said.
But the pact does not mention whether US drug agents will return to Bolivia, the world's third largest cocaine producer.
In 2008, Mr Morales, a critic of Washington's policies in Latin America, accused Mr Goldberg of inciting pro-autonomy opposition leaders in the country's eastern lowlands.
The Bolivian president - who also heads the country's coca growers' union - expelled US drug enforcement agents two months afterwards.
In response, the US sent the Bolivian ambassador back.
Correspondents say relations between the two countries have gradually improved since the row, but tensions remain.
In March, Mr Morales hit out at the US government over critical drug reports which the Bolivian leader said were intended to link his government with narcotic smuggling.


In a world first, a quadriplegic man can once again move his fingers after a chip was implanted in his brain.

Ian Burkhart from Ohio in the US can even move individual fingers to play a guitar-based computer game.
The chip reads brain signals, which are interpreted by a computer. It then precisely stimulates his muscles with electricity to restore movement.
The researchers hope the technology will eventually help millions of people with paralysis, stroke or brain damage.
Ian, 24, was seriously injured in a diving accident nearly six years ago.
The damage to his spinal cord left messages from his brain unable to reach the rest of his body and he was paralysed below the elbows and left unable to walk.
But now he is celebrating the "big shock" of being able to move his hand again after a procedure at Ohio State University.
A sensor was implanted inside his brain to read the activity of hundreds of neurons in his motor cortex.
It then took hours of practice to teach a sophisticated computer program how to understand the myriad signals in his brain.
Ian also wore a stimulating sleeve with 130 electrodes primed to stimulate and contract different muscles in his right arm.
The results, published in the journal Nature, showed he can grasp and move large objects, pour the contents of a glass and even swipe a credit card.
Ian described the early sessions as like seven-hour exams that left him "completely and mentally fatigued and exhausted".
"You really have to break down each part of that motion and think about it in a more concentrated way. For the first 19 years of my life it was something I definitely took for granted."
However, with practice he is learning new movements more quickly.
Ian is now dreaming of regaining the full function of both his hands as "that allows you to be a lot more independent and not have to rely on people for simple day-to-day tasks".
The study marks a significant moment in the field of using computers to bypass spinal cord injuries.
In 2012, a woman used her own thoughts to control a robotic arm, but now patients can control their own body again.
Dr Ali Rezai, the neurosurgeon who implanted the brain chip, said: "We're thrilled that Ian has progressed significantly with this technology.
"This really provides hope, we believe, for many patients in the future as this technology evolves and matures to help people who have disabilities from spinal cord injury or traumatic brain injury or stroke to allow them to be more functional and more independent."
One of the big challenges for the field will be to turn the spectacular feats in the laboratory into something that can be used in everyday life.
The approach requires surgery and then there are lots of trailing and bulky cables. It also needs a large computer to perform the complex algorithms to read the brain.
Also Ian's movements are not as deft as natural movement, even if they would have been unthinkable immediately after his accident.
However, the motor cortex has millions of neurons and only a few hundred are being read by the chip. It is hoped improvements in the technology will get closer to restoring true full function.
The approach of electronically bypassing an injury is just one frontier triggering excitement in the field of reversing paralysis.
Cells taken from a patient's nose have been used to repair a patient's spinal cord.
Darek Fidyka, a 40-year-old from Poland, can ride a tricycle after previously being paralysed from the waist down.
Dr Mark Bacon, from the charity Spinal Research, told the BBC: "It is encouraging to see a number of therapeutic options to restore function being explored clinically, but these clinical forays are in their infancy and largely still remain at the level of proof of concept.
"Recent reports of cell and nerve grafts, this research and numerous trials and studies now point to progress.
"Is it time to accept the bar is now set higher? Should we now measure success when we see changes in clinical practice and these proof of concepts end as standards of care?
"I don't think it is too early or unhelpful to think along such lines, even if this some way off."

Rafael Nadal and Novak Djokovic's French Open quarter-finals were postponed until Wednesday following torrential rain in Paris.

The women's quarter-finals were interrupted twice before Latvian Jelena Ostapenko and Swiss Timea Bacsinszky booked their semi-final places.
As a result of Tuesday's downpours, officials decided to reschedule the first two men's quarter-finals.
That means all four men's last-eight matches will be played on Wednesday.
Fourth seed Nadal meets fellow Spaniard Pablo Carreno Busta as he aims to move a step closer to a record 10th title at Roland Garros.
Twelve-time Grand Slam winner Djokovic, who is seeded second, plays Austrian sixth seed Dominic Thiem.
World number one Andy Murray faces Japan's eighth seed Kei Nishikori, while Swiss third seed Stan Wawrinka - the 2015 champion - takes on Croatian seventh seed Marin Cilic.
The remaining women's quarter-finals are also scheduled for Wednesday.
Czech second seed Karolina Pliskova plays France's Caroline Garcia, while 2014 finalist Simona Halep - the Romanian third seed - faces Ukraine's fifth seed Elina Svitolina.


A man has been arrested on suspicion of conspiracy to murder a Syrian-born preacher found shot dead in a car in north-west London.

Abdul Hadi Arwani, 48, from west London, was found dead on Tuesday in Wembley.
The Syrian-born British national was believed to be a critic of President Bashar al-Assad.
The Metropolitan Police said a 46-year-old man was arrested in Brent in north-west London on Sunday night.
The Met said he was being held in custody at a central London police station.
Counter-terrorism detectives have been carrying out the investigation into the death of the former imam, a father of six.
Mr Arwani was born in Syria and is believed to have attended protests against the Assad regime outside the Syrian embassy in London in 2012.
He had claimed he had been forced to flee Syria in 1982 because the country's regime sentenced him to death for photographing damage in his home city of Hama following government suppression of a rebellion.
Mr Arwani was a preacher at the An Noor mosque in Acton, west London, from 2005 to 2011.
He was found with bullet injuries to his chest in a parked car at the junction of  Greenhill and The Paddocks on Tuesday at about 11:15 BST.
Police have said they want to speak to anyone who may have seen Mr Arwani or his car, a dark coloured Volkswagen Passat, that day or on Sunday 5 April.
Officers from the Counter Terrorism Command have discovered Mr Arwani had driven on the Sunday morning near where his body would later be found and parked in Havenwood, where he remained for a short while.
A post-mortem examination found the cause of death to be gunshot wounds. An inquest is due to be opened and adjourned at Barnet Coroner's Court in the coming days.


US President Barack Obama has said he will press for further immigration reform, after Republicans condemned his use of executive powers on the issue.

Mr Obama said he had no choice but to act, accusing the Republicans of blocking a bill in Congress, and vowed to make permanent reform a reality.
The current move means that more than four million illegal immigrants will be allowed to apply for work permits.
Republicans say it will encourage more people to arrive unlawfully.
Republicans have been weighing their response to Mr Obama's executive action, but the dilemma they face is how to oppose his immigration reforms without alienating Hispanic voters - whose support they will need in the next election, the BBC's David Willis in Washington reports.
Speaking in Las Vegas, where he first outlined his plans two years ago, President Obama said: "I will never give up."
He said: "We're going to keep on working with members of Congress to make permanent reform a reality.
Astrid's moment
How did immigration debate get so toxic?
"But until that day comes, there are actions that I have the legal authority to take that will help make our immigration system more fair and more just, and this morning I began to take some of those actions.
"When members of Congress question my authority to make our immigration system work better, I have a simple answer - pass a bill."
Mr Obama said the moves that he had taken under his executive action meant that "not everybody will qualify".
"That's the truth. That's why we're still going to have to pass a bill... This is a first step, it's not the only step."
Mr Obama has insisted that his proposals, which are the biggest immigration reforms since the mid-1980s, do not amount to an amnesty.
Mr Obama added: "The bottom line is, mass amnesty would be unfair, but mass deportation would be both impossible and contrary to our country's character. That's not who we are.
"We didn't raise the Statue of Liberty with her back to the world. We did it with her light shining as a beacon to the world."
A bill was passed in the Senate last year, but the Republicans have been refusing to bring it to a vote in the House of Representatives. The party now has a majority in both chambers following the mid-term elections this month.
Earlier on Friday, Republican Speaker of the House John Boehner said Mr Obama's action had sabotaged any chance of enacting cross-party reforms and damaged the presidency itself.
He said the president had acted unilaterally "like a king or emperor" and not through a democratic process.
And he added: "The action by the president (Thursday) will only encourage more people to come here illegally. [It] also punishes those who have obeyed the law and waited their turn."
The Republican leader said Mr Obama's actions failed to take into account the wishes of the American people, adding it was not the first time the US leader had acted without the consent of Congress.
"All year long I have warned the president that by taking unilateral action on matters such as his healthcare law or by threatening action repeatedly on immigration, he was making it impossible to build the trust necessary to work together," Mr Boehner said.
The same day, House Republicans filed a federal suit over the legality of parts of Mr Obama's signature healthcare reform law, nicknamed Obamacare.
Under Mr Obama's new immigration plan, undocumented parents of children who are US citizens or permanent legal residents will be able to apply for work permits lasting three years.
There are estimated to be 11 million illegal immigrants in the US.
More than four million of them are expected to benefit from the reform package forced through using executive action, which allow Mr Obama to bypass Congress.
Only parents who have lived in the US for five years will qualify.
Another part of the package will extend a programme that gives temporary legal status to people who arrived in the US as children.
Currently only those under the age of 30 who arrived before 2007 can apply for the programme, which was launched in 2012 and already covers roughly 1.2 million people.
Mr Obama has abolished the age limit and extended the cut-off point to 2010, potentially extending the programme to a further 300,000 people.
The US leader said his measures would allow illegal immigrants to "come out of the shadows and get right with the law".
The vast majority of illegal immigrants in the US come from Mexico, according to figures supplied by Homeland Security.
They made up 59% of undocumented people in 2012, followed by El Salvador (6%), Guatemala (5%), then Honduras and Philippines (3%).


George Osborne has unveiled the biggest package of tax increases and spending cuts in a generation, in what he described as an "unavoidable Budget" aimed at tackling Britain's record debts.

But the measures - including a rise in VAT from 17.5% to 20%, a public sector pay freeze and cuts to family tax credits and housing benefits - have received mixed reactions from Lib Dem party supporters.
James Graham, of the Social Liberal Forum, founded by Lib Dem members and campaigners, said it was neither "economically literate" nor "socially just".
"We are slashing too fast and I am not happy about [the ratio of] tax rises to spending cuts," he told the BBC.
Sections of the poorest communities would be worst hit, he said, such as the young and out of work - who would be affected by cuts in benefits and measures to tackle youth unemployment.
"That generation seems to be getting put on the scrap heap. I think they would rather pay more taxes in their 40s than be in long-term unemployment," he said.
"I don't see how that helps the economy or social justice."
Benjamin Ramm, editor of The Liberal magazine, agreed that the announcement was not the "progressive" Budget promised, and instead revealed a Lib Dem failure to ensure the coalition tackled inequality.
He particularly criticised the rise in VAT, something the Lib Dem party campaigned against at the election, when they warned of the "VAT bombshell" the Conservatives would explode after polling day.
The Lib Dems were, in fact, "duty-bound" as a party to redistribute wealth as a primary priority, Mr Ramm argued.
"It is incumbent on Liberal Democrats to temper the zeal of those within the coalition who desire swift and 'savage' cuts in place of responsible, redistributive measures that assist those on lower incomes.
"This VAT rise is a tax on the poor to absolve the sins of the rich."
But around the country, Lib Dem members appeared to have already braced themselves for the worst.
Trudy Dean, leader of Kent County Council Lib Dems, said she had reluctantly accepted that tax rises and cutbacks were something "we have to bear".
"I think everybody's disappointed that VAT has become a necessary part of this package," she said. "But given the deficit, it is important that we need to make some cuts."
Judith Brooksbank, blogger and Lib Dem town councillor in Keighley, West Yorkshire, believes the Budget's contents were inevitable.
"It isn't nice to have cuts. It isn't easy. But there are times when one has to do it when one has a debt. I think it is the same nationally," she told the BBC.
She welcomed moves to support small businesses, but added that she would have liked to have heard more about funding for science and technology.
"We have to make money somewhere and I think green technology is one of those things," she said.
Roger Styring, Lib Dem deputy leader of Northumberland County Council, agreed that the Budget cuts were expected, but admitted putting them into practice would be "a painful exercise".
"County Hall here in Morpeth employs a lot of people; we are the biggest employer in Northumberland. So the mood is not good but it is not unexpected," he said.
He added: "It is a national problem and we have to work together as a nation to deliver the services people want at a price we can afford."
But for Lib Dem supporter and blogger Joe Otten, who also agreed the tax rises and cuts were necessary, the previous government was to blame for the tough Budget.
"They have already spent all the money any new taxes will raise. Yet to hear them, you'd think this was all unnecessary. We could keep spending. Deficits don't matter. Cuts are ideological," he said.
"Well maybe they are for some, but it is hardly a criticism you can make when you have Â£44bn of cuts in your own fiscal plans. To be clear, Labour do not have a leg to stand on when they criticise the first Â£44bn of cuts."


Keighley want the Rugby Football League to consider amateur video footage when they review a brawl during the club's Challenge Cup tie against Fryston, which left a player with a broken jaw.

Emmerson Whittel may need surgery on his jaw, while the club alleges player Josh Lynam was also bitten on the ear.
The RFL's match review panel will look at official video on Thursday, as it does for all on-field incidents.
Keighley have gathered additional video from spectators following an appeal.
Footage already online, shot from the stands, shows a number of fights breaking out on the field between the two sets of players.
Following the incident, Whittel posted on Twitter that brackets and bands had been used to try to re-align his jaw and that he faces at least three months out.
Keighley Cougars of League One, England's third-tier competition, progressed to the Challenge Cup fourth round with a 50-32 win over Fryston Warriors - a side from the second tier of England's amateur game.
The match, a "home" game for Fryston, was played at nearby Featherstone in West Yorkshire after the tie was at risk of being reversed and played at Keighley instead.
Keighley have also complained to the RFL about their off-field treatment before kick-off, as they allege players and members of staff were refused entry to the ground without a valid matchday ticket.
A statement on Keighley's website said: "The players' allocation of 'family and friends' tickets was then claimed to have been used to admit the playing squad and coaching staff into the ground.
"The club is outraged by this development."
The BBC contacted Fryston Warriors, who have declined to comment at this time.


A paedophile, branded "calculating and predatory", has been jailed for 15 years for a string of sex attacks on girls as young as six years old.

Andrew Hocking, 57, of West Sussex, sexually assaulted four girls, aged between six and 12, from 1976 to 1990 in Gloucestershire and Hampshire.
He was found guilty of one count of rape and six indecent assaults following a trial at Lewes Crown Court.
Sussex Police said Hocking showed "no genuine remorse" for his actions.
"Hocking stands out as cold, calculating, predatory and ruthless," said Det Con Chris Smith.
"Despite the strong evidence against him, he put the victims through the ordeal of having to recount their episodes of abuse."
Detectives discovered records of allegations of indecent assaults on a seven-year-old girl at his home in Alveston, Gloucestershire in 1976 and 1977, while they were investigated him over the making of indecent images of children.
Police were contacted by three woman claiming they had been attacked, when they were aged six, seven and 12, by Hocking at his address in Fareham, Hampshire, in the 1980s and 1990, following an appeal for information.
Following a trial, Hocking was convicted of one count of rape and six indecent assaults and cleared of one indecent assault.
The 57-year-old admitted making indecent images of children and possession of extreme pornography at an earlier hearing.
He was ordered to be put on the sex offenders register for life.


Union-led protests against public sector cuts have taken place outside a meeting to set Kent County Council's (KCC) budget for next year.

KCC has approved a 3.99% tax rise including the 2% social care precept.
The Unite union said schools, libraries and street cleaning would be cut and Unison said the 2% social care precept would not cover costs.
Conservative council leader Paul Carter said plans maintained frontline services despite financial challenges.
Unison spokesman David Lloyd said residential care providers' costs had risen and the living wage would also see expenses rise.
Referring to the social care precept, he said: "Even with the increase it's going to be difficult to make ends meet."
Eric Segal, branch secretary of Unite, which organised the protest, said: "These budget cuts, driven by a Tory government, will have an adverse affect on much-needed essential services such as schools and libraries."
He said about 80 people protested outside County Hall in Maidstone, including union members, families, students, care home staff and library workers.
Parents and pupils also protested against the planned closure of Pent Valley School, which KCC has said should shut because of declining numbers.
Mr Segal said campaigners wanted KCC to set "a people's budget" based on community needs, and use its financial reserves in order not to cut services.
"They should draw on the £50m which is sitting idly by while they are cutting services and closing down mobile libraries," he said.
The authority needs to save £126m.
Mr Carter said the social care precept would raise £11m and cover living wage costs of about £8m - but an extra £31m was needed for adult social care.
He also said changes in government legislation including increases in National Insurance and the impact of the National Living Wage had brought additional costs of £13m.
"Our grant has gone down by about £40m every year which is a significant proportion of our budget - which is about £900m," he said.
He said while the budget had reduced each year, pressure on services had risen by £55m a year.
On Wednesday, KCC said it had received an extra £5.7m from the government which made the budget "slightly more bearable".


Up to 1,100 jobs are expected to go at a Tesco call centre in Cardiff, the supermarket giant has confirmed.

Tesco said it was consolidating its customer engagement centres (CEC) into a single site in Dundee, where 250 jobs would be created.
First Minister Carwyn Jones said there would be help available to those affected at the Heath site.
Tesco said it needed to ensure its business is "sustainable and cost effective".
The company is proposing to close the Cardiff CEC in February.
Tesco boss Matt Davies said the "retail sector is facing unprecedented challenges" and it had to meet the "changing needs of our customers".
"To help us achieve this, we've taken the difficult decision to close our customer service operations in Cardiff."
Mr Jones said he had spoken to Mr Davies and "expressed my concern about the proposals".
"I pressed on the chief executive the need for a decent and generous package for the workers there," he added.
"I offered whatever help we can offer as a government and of course there will be help available to those affected by the closure."
Welsh Secretary Alun Cairns said he understood it was a "commercial decision for Tesco" but the news "will cause a great deal of concern" to workers.
He said he was "committed to working with relevant agencies, local authorities and the Welsh Government".
Union USDAW divisional officer Nick Ireland said: "Tesco's Cardiff call centre staff are understandably shocked by the announcement of the company's planned closure, they are being briefed by managers this afternoon.
"This is clearly devastating news for our members and will have a wider impact on south Wales, as so many jobs are potentially lost to our local economy."
He said the union would enter consultation talks with Tesco to look at the business case for the proposed closure.
News of the closure was raised in the Senedd by Cardiff North Labour AM Julie Morgan.
She said: "It's been there for many years - I've visited it on many occasions. What can the cabinet secretary do with this dismaying announcement?"
Economy Secretary Ken Skates replied: "I have instructed my officials to put together a package of support for those who could be affected."
Mr Skates later said it was "devastating news" for the workers.
Welsh Conservatives leader Andrew RT Davies called the Welsh Government's response a "damning indictment" of its record on jobs.
"It is scandalous that the cabinet secretary only found out about the decision 45 minutes before it was announced - when the Welsh Government should be far better connected to such a major decision," he said.
"It comes after Barclays announced the closure of its mortgage centre in Llanishen - where 180 jobs were lost."
UKIP AM for South Wales Central, Gareth Bennett, said it was a "tremendous blow" and he had written to Tesco for urgent answers on the plans.
Plaid Cymru called on the supermarket giant to clarify whether it has received any assistance to move to Scotland, or whether a cost-cutting decision has been made.
Shadow economy secretary Adam Price said: "In recent years Cardiff has seen sustained growth in the retail sector, but we're now facing a difficult future due to the weakness of the pound and the prospect of increased food inflation.
"With call centres consistently being prioritised by the Welsh Government, we need to be reassured about the future of that industry and that type of work."
Cardiff council leader Huw Thomas called the move "both surprising and disappointing".


A haul of Anglo-Saxon gold discovered beneath a Staffordshire farmer's field could help rewrite history, experts say.

Historians believe the Staffordshire Hoard could hold vital clues to explain the conversion of Mercia - England's last great pagan kingdom - to Christianity in the 7th Century.
The hoard was found buried on a farm in Staffordshire in July 2009.
The 1,500 pieces of gold are thought to be the spoils of an Anglo-Saxon battle.
TV historian Dan Snow believes the find has the potential to rewrite the history books.
Speaking on BBC1's The Staffordshire Hoard, he said the conversion of Mercia "marked the beginning of a new era in English history".
"The Staffordshire Hoard is helping shine a light on exactly how and when the transformation occurred," he explained.
Historian David Starkey said: "England, remember, isn't England at all; England has yet to be invented - the word barely exists.
"Instead, there were these rival warring Anglo-Saxon kingdoms that behaved like the worst kind of takeover bidders of the city.
"They decapitated each other - literally, not metaphorically.
"It's gang warfare, when you take over the territory of a rival gang, the lot get bumped off."
Mercia was one of Britain's largest and most aggressive kingdoms, stretching from Humber to London.
The pagan kings of Mercia resisted conversion to Christianity until it became surrounded by Christian states late in the 7th Century.
Historians believe the hoard could give the last glimpse of Paganism and the first of Christianity.
The largest-ever haul of Anglo-Saxon gold found in Britain, the Staffordshire Hoard was discovered buried beneath a farmer's field near Brownhills by amateur metal detector enthusiast Terry Herbert.
The hoard comprises more than 1,500 items, made of gold and silver, embedded with precious stones and jewels and was valued at nearly Â£3.3m.
After the Staffordshire Coroner ruled in September 2009 that the find was the "property of the Crown", arrangements were made for the valuation.
The money was split between Mr Herbert, and Fred Johnson, who owns the farm where it was discovered.
More than 40 items from the Staffordshire Hoard are on display in this summer's Tour 2011 across the West Midlands.


Francesco Guidolin is the second footy boss to be sacked in day, on his birthday as well!

The Swansea City head coach was under huge pressure after losing 2-1 to Liverpool at the weekend, with the Swans finding themselves 17th in the Premier League table.
His side haven't won a game since the opening day of the season and are only just above the relegation zone.
Guidolin is replaced by former USA coach Bob Bradley.
The American, who leaves French side Le Havre, has also managed the Egyptian national team and Norwegian side Stabaek.
The club say they think Bradley makes a good "long term appointment" to "stabilise matters on and off the pitch".
Swans chairman Huw Jenkins said he was disappointed, but said that the club "needed to change things as soon as possible" to move forward positively.
Swansea's next match is against Arsenal on 15 October, following this weekend's international break.


A Labour minority administration is to run West Lothian Council - even though the SNP has more local councillors.

It is the latest example of the largest local party being left in opposition.
Last week, a proposed coalition deal between Labour and the Conservatives in West Lothian was vetoed by the party's executive body.
Administrations have still to be formed in Edinburgh and Clackmannanshire.


Rory McIlroy missed the halfway cut at the US PGA Championship for the first time in his career as Robert Streb and Jimmy Walker lead at Baltusrol.

Northern Ireland's McIlroy, twice a winner in seven US PGA starts, bogeyed the last for a one-under 69 to finish three over and miss the cut by one.
American Walker also bogeyed the 18th for a 66 and nine-under total, matched by Streb who birdied his last for 63.
Defending champion Jason Day had eight birdies in a 65 to get to seven under.
The Australian world number one is tied third with Argentina's Emiliano Grillo (67), while Open winner Henrik Stenson of Sweden is one shot back after carding a second three-under 67 to move to six under.
Germany's Martin Kaymer (69), who won this tournament in 2010, and Americans Patrick Reed (65) and Brooks Koepka (67) are four adrift on five under.
Wales' Jamie Donaldson (67) is the highest-placed Briton at the final major of the season on four under, one ahead of world number three Jordan Spieth, who also shot 67.
With the cut mark hovering between one and two over par, McIlroy, who holed a 30-foot putt on the 17th to get to two over, thought he needed another birdie on the last.
The four-time major winner hit his second on the par-five 18th into greenside rough and took three more shots to get on the green before holing out for a bogey.
"I thought I needed to make four, so that's what I was trying to do," said the 2012 and 2014 US PGA champion.
"It was a tough lie. I hit the first one as hard as I really could considering how close the pin was to the edge of the green."
The world number four went straight to the practice green after taking 35 putts in round one but he said his efforts on Friday, when he took 30, were "pathetic".
"Putting let me down at [the US Open in June at] Oakmont and then putting let me down here again," he said.
"My tee to green game - there's not much wrong with that. It's pretty solid. If you had given anyone else in this field my tee shots this week, they would have been up near the top of the leaderboard.
"It just shows you how bad I was around the greens."
The Swede was grouped with the year's other two major winners - Masters champion Danny Willett and US Open victor Dustin Johnson - and he outscored them on both days.
He dropped to one under par after three-putt bogeys on the 12th and 13th holes but a three-foot eagle putt on the par-five 18th, his ninth, followed by three birdies on the front nine, moved him one clear of the field.
"I got off to a bit of a wobbly start and stood over a six-foot putt on the 14th to avoid going three over, so I'm quite happy that went in and I turned it on from 18," said the 40-year-old, who won his first major at Royal Troon two weeks ago.
"That could easily have gone the wrong way but I was hanging in there and got the good stuff coming in."
Willett birdied the ninth to card a 70 and make the cut on one over, but pre-tournament favourite Johnson is going home after adding a 72 to his opening 77 for a nine-over total.
Neither American has never won a major and while Walker has five victories on the PGA Tour, Streb has just one and has missed nine cuts in 23 events in 2016.
Walker, 37, made a solid start to round two with two birdies and seven pars in his opening nine holes before moving clear of the field with a run of three successive birdies from the 12th.
He pulled his tee shot on the 17th into a hospitality area and escaped with a free drop and par five but an almost identical shot on the last was not so lucky, ending up in a lake and resulting in a dropped shot.
"The finish wasn't what I was looking for, but it's fine," said Walker. "I think you take 66 at any tournament all day every day. So it's good.
"I will watch the leaderboard on Saturday. I don't think that's a big deal. I enjoy watching it. I think you need to know where you are at."
Streb started on the 10th and had four birdies and a bogey in his opening nine holes and closed with three in four holes to become the 30th player to card a 63 in a major - no player has ever shot a 62.
The 29-year-old, who missed the cut at each of the first three majors of 2016, said he turned up this week "just to see if I could play some good golf and have fun".
He added: "Obviously it's going pretty well, but my expectations are pretty low, which maybe is a good thing."
Day was Friday's other big mover, knocking in seven birdies in eight holes from the eighth to sit two off the lead.
"I kind of gave myself a little bit of a kick up the bum with the double bogey on seven," he said.
"It was a bit of a mess but to come back and birdie eight and nine made things a lot better for me on the back nine."
Former world number one and two-time major winner Spieth had five birdies in his opening nine holes to get to four under par but missed several opportunities to better his score on his back nine, while a bogey saw him close on three under.
"It was a really solid round and I'm back in contention," said the American. "I'm hitting the ball fantastic. I just can't get a putt to go in from beyond 10 feet."
Kaymer, who started at four under, began the front and back nines with bogeys but three birdies in his last four holes lifted him to five under.
"I made a few putts here and there. I enjoyed the last few holes," he said. "It was important for me to finish the way I did."
Andrew Johnston continued to impress in the majors, after finishing tied for eighth at The Open, with a one-under-par 69 to reach halfway at one under.
The Englishman, better known by his nickname 'Beef', started on the 10th and was two under after nine holes. He dropped back to level with bogeys on the fifth and seventh holes, but he then birdied the eighth.
"Every hole, man, I get so many nice comments," said the 27-year-old. "Even after the fifth hole, when I three-putted, they are like, 'Don't worry, Beef, come on, bounce back, you've got this one'. And it's just nice, man. It's a nice atmosphere."
Lee Westwood (70) hit 92% of greens in regulation as he also finished on one under, alongside fellow Englishmen Ross Fisher (73) and Tyrrell Hatton (68).
Andy Sullivan, who reached five under, dropped away with six bogeys in nine holes through the middle of his round before finishing birdie-eagle on the two par-five finishing holes to post a 71 and a two-under total that matched Paul Casey (69).
Scotland's Russell Knox is also playing the weekend after a second 70 left him level par, along with Wales' Bradley Dredge.
English pair Matthew Fitzpatrick (70) and Justin Rose (72) beat the cut by one shot.


A man who raped and murdered a teenage girl in 1982 has been sentenced to life in prison with a minimum of 25 years.

James Warnock, 56, strangled 17-year-old Yiannoulla Yianni in an attack described as "cruel, brutal and without mercy" at her north London home.
Recorder of London Nicholas Hilliard QC told the Old Bailey Ms Yianni had endured a "terrifying ordeal" at knifepoint.
The jury took two hours to convict Warnock, a divorced father of two.
How a killer was brought to justice after 34 years
Ms Yianni, who was known as Lucy, was from a Greek Cypriot family from Hampstead. Warnock lived just half a mile away from their house.
He managed to evade justice for 34 years, despite still living in the local community, and was only caught by a chance DNA match.
When the roofer was caught sharing indecent pictures of children on the internet last year he gave a routine DNA sample. It matched a profile retrieved from a semen stain at the 1982 crime scene. The match was one in a billion.
At the time of Ms Yianni's murder, DNA testing had not been invented and the sample that helped convict Warnock was only fully recovered from a bed sheet in 2003.
Sentencing Warnock, Judge Hilliard said: "It is impossible to understand how one human being could do such things to another.
"In the process you visited misery beyond measure on those to whom Yiannoulla was, and is, so dear and which will never leave them."
Following the verdict, the Yianni family described how Lucy's murder had left them "saturated by grief" although they always believed her killer would be caught.
Her brother Rick said: "Thankfully the long arm of the law has reached out from the past to bring this evil being to justice."


Theresa May is seeking to hold a snap general election on 8 June.

Throughout this election campaign we are taking and answering your questions about the issues which matter most to you.
If you want to know where the parties stand on Brexit, the NHS, education, or an issue which you believe deserves more attention, let us know.
If you're concerned how boundary changes could affect your vote or if you don't know how to vote, get in touch.
If we ask or answer your question, we will do our best to let you know and may ask you to be part of the process on air, too!
Here are some of your questions we answered earlier.
Whatever you want to ask about the general election, please use the box below.


Holding the 8 June general election is expected to cost the taxpayer more than £143m, the BBC understands.

The government estimate is an increase of 16% from the £123m it budgeted for the 2015 general election.
The price tag reflects the scale of the operation to staff tens of thousands of polling stations, process millions of votes and distribute candidates' mailings.
The cost of last year's EU referendum was similar.
That cost the taxpayer around £142m.
Taking the 2015 election as a guide, around 7.6 million postal votes were sent out. There were over 46 million poll cards and ballot papers printed to reflect 650 separate candidate lists for the election.
On the day of the vote itself, 41,000 polling stations were staffed for many hours by tens of thousands of people.
That evening, more than 30 million votes were counted by tens of thousands of people sorting through thousands of ballot boxes.
Holding national votes has become an expensive business.
Based on the government's estimate, obtained from the Cabinet Office and Northern Ireland Office, this would become the UK's most expensive election.
Since 2010, holding by-elections have on average each cost close to £240,000.
Costs for 8 June are higher than previous elections because this poll is being held on a stand-alone basis. Often joint local and national elections are held, where administrative costs can be shared between different bodies polling on the same day, such as councils.
The anticipated costs may also reflect expectations over turnout, the number of candidates and parties standing and how many people are expected to vote.
The deadline to hold the national poll on the same day as this May's local elections had passed by the time Theresa May surprised many in Westminster and called for a snap election.
As a result, returning officers in England, Scotland, Wales and Northern Ireland have been allocated up to £101.6m in total for the 8 June poll.
The cost of delivering election mailings for candidates is expected to match the £41.7m spent on the 2015 general election, according to the Cabinet Office.
Spending by individual candidates and political parties on the campaign trail is treated separately.
For the 2015 general election, there was a total reported spend of over £39m by 57 parties and 23 non-party campaigners, according to the Electoral Commission.


The athletics world has been shocked by new evidence that suggests hundreds of competitors may have cheated to win medals.

Athletes push themselves to the limits to win competitions and are regularly tested to make sure they are not using anything illegal to improve their performance.
However a secret list has just been revealed which suggests that hundreds of athletes might have taken drugs, or banned supplements, to try to help them win.
It was shown to the Sunday Times newspaper in the UK, and a TV station in Germany, and reveals the results of huge numbers of abnormal blood tests going back to 2001.
The people who run the sport - the International Association of Athletics Federations - say they've always worked hard to make sure athletes can't cheat and will continue to carry out tough testing programmes.

Sooner or later, and it may well be sooner, there is going to be a serious test of the power of Commons select committees to summon unwilling witnesses to give evidence before them.

A number of "refusenik" cases are piling up.
Top of the list is Mike Ashley, the owner of Sports Direct, who, after refusing earlier invitations, has been summoned to give evidence to the BIS Committee on 7 June, and so far shows no sign of being prepared to appear.
And there's also the case of Matthew Elliott, chief executive of Vote Leave, who has displeased the Treasury Committee by failing to appear for its Brexit inquiry.
If a witness declines a select committee summons, their refusal can be treated as a matter of Parliamentary privilege, which would require the committee to seek leave from the Speaker to bring a motion before the House of Commons.
Were the motion to be passed, we could then have the entertaining sight of the Serjeant at Arms, in full regalia, setting off to apprehend the miscreant and bring them to Westminster. Except for the minor difficulty that the Serjeant has no powers of arrest or entry, and the police would have no legal basis to assist him, so the whole thing could become rather embarrassing.
The reality is that the House's powers to compel reluctant witnesses are legally pretty shaky. But witnesses could find that there is a price to pay if they refuse to turn up. Rupert Murdoch originally declined a request from the Culture, Media and Sport Committee to give evidence on phone hacking - but eventually did attend the session where he was, famously, custard-pied. Why? Because his company was suddenly facing considerable reputational damage over phone-hacking, and possibly because suggestions were made that a failure to appear could lead to questions about whether he was a "fit and proper person" to run a TV company in the UK.
Such considerations will not apply to all witnesses.
So what happens if someone either refuses point-blank, or simply fails to turn up at the appointed hour?
Here the plot thickens.
It is possible to imagine that there may not be unanimous support for going nuclear and treating non-attendance as a matter of privilege. This could manifest itself on the select committee in question, or at the Liaison Committee (the super-committee of all select committee chairs) which might also wish to weigh in. Or a motion to the House might be opposed by some MPs, especially if the government, for whatever reason, wasn't keen.
The motion could either condemn refusal by the witness, or, more likely, refer the issue to the Privileges Committee - so that the original committee would not be acting as judge and jury in hearing its own complaint. It would also give the reluctant witness another opportunity to comply, or to make their case to the Privileges Committee itself. But any hint of dissent or doubt among MPs would weaken the pressure on them to play ball.
So suppose the witness remains obdurate? The Privileges Committee would be left with little option but to rule that their refusal was contempt of Parliament.
At that point they hit real difficulties; the Commons' ancient powers to fine, or even jail, offenders are incompatible with human rights law. No-one has been fined by the Commons since 1666, and no-one has been jailed for contempt since 1880.
The alternative of summoning the witness to the Bar of the House for a telling-off by Mr Speaker is fraught with danger; they might refuse to appear, at which point we're back to Square 1, or they might turn up and stage an embarrassing, and televised, scene by answering back as the Speaker attempted to rebuke them.
There are, however, other sanctions - the Privileges Committee could recommend that the offender should be formally "admonished" by a resolution of the House, after a fair process of investigation had established that they were in contempt; that could have all kinds of implications - they could be disqualified as a company director, or lose "fit and proper person" status to hold some kind of licence in the UK.
And similar issues might arise if the witness did appear, if they were to be over-combative, or if they refused to answer certain questions.
Today's news that Sir Philip Green is prepared to appear before the BIS and Work and Pensions committees, to answer questions arising out of the troubles of BHS, removes one possible refusenik from the list accumulating on the committee corridor - but there could be a real issue about what he was able to say while under investigation by the Insolvency Service.
So all of this awaits a test case.


"It's like this thing was aliveâ€¦it was churning, moving aroundâ€¦making noises, you knowâ€¦like a growl."

It's an image that still haunts police officer Deputy Douglas Duvall who, on the evening of 28 February 2013, responded to an emergency call in the suburban calm of Tampa, and found himself face to face with the Florida underworld.
Inside a detached bungalow, the ground had opened and swallowed the sleeping body and the bed of 37 year-old Jeff Bush.
His brother Jeremy was frantically trying to dig him out, but Jeff's body was sucked into the depths and never found.
Horizon: Swallowed by a Sinkhole
Driveway sinkhole woman 'lucky'
Only the efforts of first responder Douglas Duvall hauling Jeremy out of the churning pit prevented a second tragedy.
The natural trapdoor that opened up and claimed the life of Jeff Bush is called a "sinkhole". It is far from the only case.
In the last few years, vast sinkholes have appeared overnight from as far afield as China and Guatemala, but it's Florida where the fear is greatest.
Just last August, a resort complex near Disney World collapsed into a huge 20m hole.
It was to investigate this devastating phenomenon that I travelled to Florida to try to understand what caused the sinkhole that killed Jeff, and why the geology of this state makes it the sinkhole capital of the world.
It's possible to explore some of these natural shafts and descend within the voids beneath, at places like Ladder Cave in Citrus County.
Here you can see how acid-tinged rain and ground water slowly eats away at limestone bedrock below, producing cavities in the subsurface.
Often, surface sand and mud gets washed into these to fashion a pockmarked landscape of pits and depressions which we call karst.
The trouble is, sometimes, the subterranean world of caves and caverns break through the surface cover to drag down whatever lies above.
These "cover-collapse" sinkholes are the deadly threat that lurks in the Florida underworld.
Investigations revealed that a cover-collapse sinkhole had lain directly beneath Jeff Bush's bedroom.
Bill Bracken, the structural engineer who worked with the emergency workers at Jeff's house, showed me the footage that he took from within the hole that fateful night.
It makes chilling viewing. When it opened and soil began to fall inward, a suction force was exerted on the concrete floor above, eventually wrenching it down along with everything in that room.
Sinkhole collapses are pretty commonplace across Florida. Virtually the whole of the Sunshine state, from the Keys in the south to the border with Georgia in the north, is a vast limestone platform that is flushed with groundwater below and has a humid climate that rains down plenty from above.
That water keeps the lawns green, fills the swimming pools and provides drinking water for millions. But the waters are also consuming Florida's soluble limestone foundations.
The result is a state collapsing in on itself. Amid the city streets, quiet suburbs and citrus groves, holes are often opening up to reveal a new hidden Florida.
Residents are, understandably, nervous about the Florida concealed beneath. As soon as any cracks appear in their buildings, nervous homeowners call in geotechnical experts.
Over 6,500 sinkhole insurance claims are reported each year. All of which makes Florida's sinkholes a boom for lawyers and geologists.
What is not commonplace are sinkhole tragedies. Jeff Bush's death is Florida's first fatal sinkhole collapse in decades.
His suburban district of Seffner lies in a sinkhole "sweetspot" - a cluster of collapses pepper the west central part of the state around the city of Tampa.
His death has created unease among the sedate, retiring gated communities of west Florida. Because the sinkhole scourge is on the rise.
Quite why sinkholes are becoming ever more prominent in Florida is uncertain. Their triggers are enigmatic, though the fact that there is a "sinkhole season" suggests that Florida's climate has something to do with it.
In the summer months, the Gulf Coast's hurricanes deluge the state, dumping tonnes of water on the land over a matter of hours, weighing down the soil and collapsing the roofs of caves below.
In the dry season, drought conditions can lower the water table, reducing pressure in water-filled voids and causing their unsupported sides to implode.
Dramatic changes to the Floridian water table can also come from another more surprising source. The state's warm, wet weather and fertile soil cover has made it ideal for agriculture, and makes it, alongside California, the fruit basket of America.
Its famous citrus groves and fruit fields are irrigated in part from groundwater drawn from Florida's underground aquifer.
Unlike the year-round warmth of California, the winter months in Florida can be cold and its fruit, particularly its vast strawberry crop, is prone to frost damage.
So when sudden cold snaps strike, farmers respond with an intense spraying of warm groundwater onto the strawberry fields.
This aggressive groundwater pumping, however, can drop aquifer levels by tens of metres overnight. When this has happened in the past, large numbers of sinkhole collapses have occurred.
There is no evidence that groundwater pumping for agriculture was the trigger for last year's lethal collapse in Seffner.
However, it is a reminder of the growing human pressures that are being placed on Florida's natural support system.
The lure of the Florida sun is drawing ever more people to the state, and our urban sprawl is advancing into wild land primed with lethal sinkhole traps. In the past, they would have gone unnoticed. But not now.
So, in a way, the real reason for Florida's growing toll of sinkhole damage is ourselves.

Several ministers from Yemen's exiled government have returned to the country for the first time since being forced to flee by Houthi rebels in March.

The ministers, accompanied by senior intelligence officials, flew by helicopter to a military base on the outskirts of the southern city of Aden.
They were to make preparations for the government's return, officials said.
Southern militiamen backed by Saudi-led air strikes have driven the rebels out of much of Aden in the past three days.
On Wednesday, they retook the main seaport and neighbouring district of Mualla.
A government official told the Reuters news agency the delegation that flew into Aden on Thursday included the ministers of interior and transport, a former interior minister, the intelligence chief and deputy speaker of parliament.
President Abdrabbuh Mansour Hadi had told them to "prepare the security situation and ensure stability ahead of a revival of the institutions of state in Aden", the official added.
A major offensive to regain control of Aden, dubbed "Operation Golden Arrow", was launched on Monday by local militiamen from the Popular Resistance Committees (PRC) and Yemeni soldiers recently trained in Saudi Arabia, which is leading a coalition of mostly Sunni Arab countries.
With the help of air strikes and about 100 armoured vehicles reportedly provided by the coalition, they have been able to recapture the city's seaport, the international airport, and a large proportion of the peninsula where much of Aden is located.
On Thursday, local fighters told Reuters that they were besieging the two main districts still under Houthi control, and that a key checkpoint outside the city was being shelled by coalition warships deployed in the Gulf of Aden.
The losses in Aden represent the biggest setback for the Houthis since the Saudi-led air campaign against them started on 26 March, a day after the rebels and soldiers loyal to ousted former president Ali Abdullah Saleh entered the city.
Mr Hadi had taken refuge there the previous month after the Houthis consolidated their control of the capital, Sanaa, and placed him under effective house arrest.
The offensive in Aden began after the collapse of a ceasefire that was supposed to have taken effect before midnight on Friday to allow for aid deliveries.
The UN says more than 3,200 people, half of them civilians, have been killed in air strikes and fighting on the ground in the past 15 weeks.
Another one million civilians have been displaced by the conflict and more than 80% of Yemen's 25 million people now need some form of humanitarian aid.


More than 100 school janitors in Glasgow are to stage a three-day strike next week in a dispute over pay.

The union, Unison, said more than 130 members employed by Cordia - an arms-length body of Glasgow City Council - could take part in the action.
It wants additional payments for staff undertaking tasks which are dirty, unpleasant, involve regularly working outside or involve heavy lifting.
Cordia said it would make sure affected schools would be open.
A Cordia spokesman said: "We will make sure that affected schools are open and that any disruption is kept to a minimum. The majority of our janitors are not involved and will continue to work normally."
Unison said that Cordia was "refusing to pay a Working Context and Demands Payment to school janitors" and was "using spurious arguments to justify not making this payment".
The payment covers "dirty, unpleasant" tasks and those that "involve working outside on a regular basis or heavy lifting".
The annual payment ranges from Â£500 to Â£1,000.
Unison said its members had been boycotting disputed duties for six weeks and had decided to escalate their action as Cordia and the council had refused to reach a negotiated settlement.
Unison Glasgow branch officer Sam Macartney said: "Unison is very clear that school janitors meet the criteria to be awarded this payment.
"Our members have been left with no option other than to take this action as both Cordia and the council are wrong and just not listening to our members."


Manchester City will not face any Uefa sanctions after their fans booed the Champions League anthem.

Uefa's disciplinary body reviewed the case after fans booed before the 2-1 home win over Sevilla on 21 October.
The case was considered after a report by the European governing body's delegate at the match.
A Uefa spokesman said: "It is confirmed that the Uefa control, ethics and disciplinary body has decided to close the disciplinary proceedings."
City's fans are understood to have booed the anthem repeatedly over the past year to express anger at Uefa over a number of issues.
The club were fined £16.3m in May 2014 after breaching Financial Fair Play restrictions.
A City fan group also led a protest against Uefa after 650 CSKA Moscow supporters gained access to the Arena Khimki for their Champions League game in October 2014, despite the Russian club being ordered to play it behind closed doors.
Media playback is not supported on this device
CSKA were handed the sanction as punishment for a series of offences including racist chanting.
Uefa's decision to take no action over the anthem had been expected after the organisation's general secretary Gianni Infantino said two weeks ago that fans had a right to boo anything they wanted.
The report of the booing had been made by match delegate Geir Thorsteinsson, the chairman of the Iceland Football Association, which led to disciplinary proceedings being opened.
Meanwhile, City manager Manuel Pellegrini has declared striker Sergio Aguero fit for Saturday's Premier League home match against Liverpool.
The Argentina international has been absent for seven matches with a hamstring injury sustained while playing for his country in a World Cup qualifier against Ecuador in October.
"Sergio is fit, he's ready to come back," said Pellegrini, who added that City will be without playmaker David Silva (ankle), striker Wilfried Bony (hamstring) and captain Vincent Kompany (calf).
Winger Raheem Sterling is set to face his former club for the first time since a £49m move from Liverpool in July.
Pellegrini said: "I always think it is special for the player to play against his former side. Not only for Raheem, but for any player to face a team for whom they played for many years.
"I always say that Raheem is a very young player. He must improve a lot, but I am very happy with the way he is playing so far."


Rescue teams have recovered the body of a man from the wreckage of a Cardiff church which collapsed.

The man was trapped under a pile of rubble when the derelict church crumbled in Splott at about 14:50 BST on Tuesday.
Two others escaped with minor injuries following the incident close to the main south Wales to London railway line.
South Wales Police is investigating the incident at the building.
The building was in the process of being demolished.
It follows a report for Cardiff council in June 2016 which warned the building was a "dangerous structure" at risk of "imminent collapse".
Report authors Bruton Knowles warned part of the building close to the railway line was unstable and needed to be stabilised or it may "fall" and damage the tracks.
The report warned: "In our opinion, the building may be deemed as a dangerous structure. In consideration of the close proximity of the railway line."
The structural survey was undertaken for Network Rail ahead of work to replace a bridge nearby, as part of rail upgrades.
Cardiff demolition firm Young Contractors, which has been working on the derelict church for about three weeks, confirmed none of its staff were on the site at the time.
Cardiff council said police were investigating.
Stephen Doughty, MP for Cardiff South and Penarth, has said on Twitter "questions must be asked".
Firefighters, rescue dogs and a drone had been searching for the man who was found on Tuesday between 20:00 and 21:00, police said, adding formal identification would now take place.
Splott Road is still closed in both directions following the church collapse while closures also affect Pearl Street and Agate Street.


A former son-in-law of Kazakhstan's president who later became a prominent opponent has been charged with murder by prosecutors in Austria.

Rakhat Aliyev, a former ambassador to Austria, is accused of killing two bank managers in his home country in 2007.
Kazakhstan has attempted to have him extradited to face trial, but Austria has twice refused because of the former Soviet republic's human rights record.
Instead, Austrian prosecutors opened their own murder investigation in 2011.
Mr Aliyev has denounced the case against him as politically motivated.
However, in June he flew voluntarily to Vienna from his home in Malta and handed himself in to the Austrian authorities. Since then, he has been held in "investigative custody".
On Tuesday, a court in Vienna said Mr Aliyev had been charged.
A spokeswoman for the court told the Reuters news agency that the judge had not set any bail option and that Mr Aliyev's lawyers had two weeks to appeal against the charges.
He faces at least 10 years in prison if found guilty of murder. If extradited to Kazakhstan he could face a sentence of up to 40 years.
Mr Aliyev was once married to Kazakh President Nursultan Nazarbayev's eldest daughter, Dariga.
A businessman with extensive contacts among the Kazakh elite, he spoke out against Mr Nazarbayev after being sacked as ambassador to Austria.


Following a three month delay, trams have started running from Birmingham New Street station.

Centro's Midland Metro extension from Snow Hill travels via Corporation Street to Wolverhampton.
Construction of the 0.7 mile (1.2km) track extension was halted over the busy Christmas period and was due to be completed in February.
Further lines to Edgbaston and Centenary Square are planned in the Â£128m project.
When the delays of the track were announced, Phil Hewitt, from Centro's Midland Metro, said: "A stringent testing programme has identified minor anomalies in some of the track alignment which need to be addressed".
Jonathan Cheetham, from Retail Birmingham, said the tram system "gives us huge credibility as a city".
"Investors from abroad, which we've seen a lot of recently, know and understand how important transport is," he added.
