Final clinical trials of a malaria vaccine - the first to reach this stage - suggest it could help protect millions of children against malaria.

But tests on 16,000 children from seven African countries found that booster doses were of limited use and vaccines in young babies were not effective.
After children aged 5-17 months were given three doses of the vaccine, the immunisation was only 46% effective.
But experts say getting the vaccine this far is a scientific milestone.
Data from the trial published in The Lancet showed that the success rate fell to even lower levels in younger infants.
Scientists have been working on the vaccine for more than 20 years, but observers believe there is still a long way to go.
RTS,S/AS01 is the first malaria vaccine to reach advanced trials and show any sign of working in young children.
There is currently no licensed vaccine against malaria anywhere in the world.
With around 1,300 children dying in sub-Saharan Africa from malaria every day, scientists say they are delighted to have got to this stage in developing a vaccine against a very clever parasite.
Prof Brian Greenwood, study author and professor of clinical tropical medicine at the London School of Hygiene and Tropical Medicine, said he was "a little disappointed" by the results of the clinical trials.
"I hoped the vaccine would be more effective, but we were never going to end up with the success seen in measles vaccines with 97% efficacy."
That is because the malaria parasite has a complicated life cycle and it has learnt how to evade the immune system over hundreds of years.
The vaccinations took place at 11 sites across Burkina Faso, Gabon, Ghana, Kenya, Malawi, Mozambique and Tanzania.
The trials found the vaccine's ability to protect children gradually waned over time.
Scientists tried to bolster this with a booster, but protection never reached the level provided by initial doses.
The clinical trials also found that meningitis occurred more frequently in children given the vaccine.
However, Prof Greenwood said the data was very robust and the vaccine could still reduce attacks of malaria by around 30%.
The European Medicines Agency will now review the data and, if it is satisfied, the vaccine could be licensed.
And the World Health Organization could then recommend its use in October this year.
Prof Adrian Hill, at the University of Oxford, said although the study was "a milestone", he had concerns.
"Because the vaccine's efficacy is so short-lived, as expected a booster dose is shown to be of some value - but it was not as effective at the initial doses.
"More worrying is the new evidence of a rebound in malaria susceptibility: after 20 months, vaccinated children who were not boosted showed an increased risk of severe malaria over the next 27 months compared to non-vaccinated controls."
Overall, he said the vaccine's potential public health benefits were not yet clear.
"It should be possible to make the vaccine more effective in some settings, but that will probably increase delivery costs substantially."
Prof Mike Turner, head of infection at the Wellcome Trust, said it had taken two decades to get to this point.
"While the levels of protection the vaccine offers against clinical malaria may seem relatively low, they are better than any other potential vaccine we currently have.
"The findings are not only important in their own right but also in signposting a road to developing better vaccines in the future."
James Whiting, from the charity Malaria No More UK, said it was a huge achievement to get the vaccine this far.
"There are still a number of considerations and approval processes to be undertaken, but it has the potential to be an important additional tool to fight malaria and save lives from a disease that kills a child every minute."
Other experts warned that funding for a vaccine should not be redirected away from insect nets and other malaria control measures.


Republican presidential hopefuls have denounced the Colorado Planned Parenthood shooting, but they dismiss allegations from the left that their recent condemnations of the nation's largest abortion provider may have provoked the attack.

In the last few days, Republican presidential candidates have called the shootings at a Colorado Planned Parenthood clinic a "tragedy" (Carly Fiorina), the work of a "sick person" (Donald Trump) and "senseless violence" (John Kasich).
They've offered prayers "for the loved ones of those killed" (Ted Cruz) and said there is "no acceptable explanation for this violence" (Jeb Bush).
Others, such as Florida Senator Marco Rubio and New Jersey Governor Chris Christie, have yet to issue a response.
When asked, however, most of the Republican presidential hopefuls have emphatically denied that the murders are in any way the result of the heated rhetoric that has swirled around Planned Parenthood on the campaign trail over the last few months.
Condemnations of the family planning organisation had become standard fare for Republican candidates ever since hidden-camera videos released in July revealed Planned Parenthood employees speaking matter-of-factly about the cost of providing tissue from aborted foetuses to research groups.
Conservatives in Congress attempted unsuccessfully to cut off government funding for Planned Parenthood's non-abortion-related healthcare services. And during the Republican presidential debates, nearly every candidate denounced the organisation.
Mr Cruz called Planned Parenthood a "criminal enterprise" whose employees have essentially confessed to committing "multiple felonies".
"I would encourage every American to watch the videos," he said. "See your Planned Parenthood officials callously, heartlessly bartering and selling the body parts of human beings and then ask yourself, 'Are these my values?'"
Mr Bush called the videos "horrifying".
Planned Parenthood "doesn't seem to understand the sanctity of human life and is willing to destroy that," retired neurosurgeon Ben Carson said.
Ms Fiorina was widely considered to have won the second Republican debate with an impassioned condemnation of what she said was shown in one of the Planned Parenthood videos.
"I dare Hillary Clinton, Barack Obama to watch these tapes," she said. "Watch a fully formed foetus on the table, its heart beating, its legs kicking while someone says we have to keep it alive to harvest its brain. This is about the character of our nation."
The videos did not, in fact, show such an occurrence - but they did include an interview with a research technician who described something similar.
The alleged perpetrator of the Friday shootings, Robert Dear, is reported to have said "no more baby parts" after being apprehended by Colorado police - a piece of information that has been seized upon by abortion rights supporters.
"It is offensive and outrageous that some politicians are now claiming this tragedy has nothing to do with the toxic environment they helped create," Planned Parenthood executive vice president Dawn Laguens said in a statement on Sunday.
"One of the lessons of this awful tragedy is that words matter, and hateful rhetoric fuels violence. It's not enough to denounce the tragedy without also denouncing the poisonous rhetoric that fuelled it."
Congresswoman Debbie Wasserman Schultz, chair of the Democratic National Committee, called the Colorado shootings "an act of terrorism".
"Those running for president and those of us in leadership roles in our country's major political parties have an obligation to denounce these attacks and clearly say that violence and intimidation in the pursuit of ideology are not acceptable in America," she said in a press release.
Some Republican candidates have bristled at such charges.
"This is so typical of the left to immediately begin demonising a messenger because they don't agree with the message," Ms Fiorina told Fox on Sunday. "What I would say to anyone who tries to link this terrible tragedy to anyone who opposes abortion or opposes the sale of body parts is, this is typical left-wing tactics."
Mr Cruz said in Iowa on Sunday that there's been "vicious rhetoric" from the left trying to blame anti-abortion advocates for the assault. He said based on the little evidence so far, it's just as likely to reach other conclusions about Dear's motives.
"It's also been reported that he was registered as an independent and a woman and a transgendered leftist activist," he said, referring to the fact that Dear listed his gender as female in a Colorado voter registration database. "If that's what he is, I don't think it's fair to blame the rhetoric on the left."
Mr Trump, asked about Dear's reference to "baby parts", noted that there was considerable "anxiety" and "dislike" among his supporters for Planned Parenthood.
"There is a tremendous group of people that think it's terrible, all of the videos that they've seen with some of these people from Planned Parenthood talking about it like you're selling parts to a car," he said. "There are a lot of people that are very unhappy about that."
Former Arkansas Governor Mike Huckabee called the attack "domestic terrorism" - although he made sure to point out what he views as the nature of abortion.
"There's no excuse for killing other people, whether it's happening inside the Planned Parenthood headquarters, inside their clinics where many millions of babies die or whether it's people attacking Planned Parenthood," he told CNN on Sunday.
When asked about the increasingly sharp accusations, Mr Carson called for cooler heads to prevail.
"We must somehow manage to regain the high ground and understand that we're not each other's enemies, even though we may have some differences of opinions about things," he said on NBC. "Let's stop trying to destroy each other."
With the Colorado shootings taking place in the middle of a heated presidential campaign season and the US Supreme Court set to hear the first major abortion-related case in eight years, however, the high ground seems very far away.


Having cake at work to celebrate colleagues' birthdays, engagements or just surviving the week is a danger to health, a senior dentist argues.

Prof Nigel Hunt, from the Faculty of Dental Surgery, at the Royal College of Surgeons, says "cake culture" is fuelling obesity and dental problems.
At the organisation's annual dinner for dentists, he will say workplace temptation stops people losing weight.
And staff should be rewarded with fruit, nuts or cheese instead.
In the speech, he will say: "Managers want to reward staff for their efforts, colleagues want to celebrate special occasions, and workers want to bring back a gift from their holidays.
"But for many people the workplace is now the primary site of their sugar intake and is contributing to the current obesity epidemic and poor oral health."
He will say nearly 65,000 adults every year need hospital treatment for tooth decay.
Prof Hunt will say: "Cake culture also poses difficulties for those who are trying their hardest to lose weight or become healthier - how many of us have begun such diets only to cave in to the temptation of the doughnuts, cookies or the triple chocolate biscuits?"
While he does not believe office cake should be banned, he will say it should be purchased in smaller quantities and consumed only with lunch.
Dentists recommend cutting down on sugary or starchy foods between meals as they give bacteria fuel to produce acids that decay teeth.
At the dinner, which is being rounded off with mint panna cotta, British strawberries and chocolate soil, Prof Hunt will say: "Ideally office workers should consider other alternatives altogether like fruit platters, nuts, or cheese.
"Responsible employers should take a lead and avoid such snacks in meetings."

Written complaints made by customers to their water providers have fallen for the sixth year in a row in England and Wales, figures from a watchdog show.

There was an 18% fall in complaints in 2013-14 compared with the previous year, to 123,218, the Consumer Council for Water said.
This was the lowest level since the watchdog was formed in 2005.
However, it said that this momentum could be lost if water companies failed to deliver affordable bills.
Billing and charges still account for the highest proportion of complaints, some 57% of all gripes.
Four companies - South West Water, Affinity Water, Severn Trent Water and Dŵr Cymru Welsh Water - reported an increase in complaints.
Southern Water and South East Water, while reporting drops in complaint numbers, were described as remaining "too far adrift" of the rest of the industry.
Darren Bentham, Southern Water's chief customer officer, said: "While our performance in 2013/14 saw a big improvement, we are still lower down the results table than we want to be - and where our customers want us to be. However, we are continuing to make changes which ensure we focus on our customers - from training, to new systems and an improved website."
Steve George, customer services director at South East Water, said: "Although our focus is to prevent problems, when things go wrong for our customers we are always sorry and we endeavour to fix things as quickly as possible."
In August, regulator Ofwat proposed that household water bills in England and Wales should go up less than the rising cost of living in the next five years.
It proposed that bills should be an average of 5% lower, before inflation was applied, by 2019-20.
Although telephone complaints were also falling at the same time as written complaints, these trends could reverse if prices were not set at the correct level, the Consumer Council for Water said.
"Affordability remains a huge challenge for the industry with one in five customers telling us their water bill is not affordable," said Tony Smith, the watchdog's chief executive.
"Water companies and the regulator Ofwat must deliver prices for the next five years that customers can afford and find acceptable or risk a backlash from struggling households."


The European Space Agency (Esa) has a new director general from Wednesday.

Johann-Dietrich Woerner vacates his chairmanship of the German space agency (DLR) to take the reins at the Paris-based organisation for an initial period of four years.
He succeeds Frenchman Jean-Jacques Dordain, who had been in post since 2003 - the longest any individual has been DG in the agency’s history.
Mr Woerner has told delegations that he will be reviewing Esa’s structure.
Current directors are staying in post, but there is likely to be change in the coming year as he draws new lines of responsibility for Esa's executive.
The agency’s most high-profile mission currently is Rosetta and its investigations at Comet 67P, but the future programme is a busy one, as the agency seeks to build a new rocket, extend its participation in the space station, land on Mars, loft constellations of sat-nav and Earth-observation spacecraft, while at the same time overhauling Europe’s weather satellites.
"After harvesting the seeds my next task to fulfil is continuation," Mr Woerner told reporters at the recent Paris Airshow.
"It's very simple: it's Ariane 6, it's ISS, it's ExoMars, Galileo, Copernicus , MSG, MTG, EDRS, and so and so on.
"There are a lot of programmes running, and it will be my automatic duty to continue in these programmes together with the member states, the executive and all Esa staff."
Mr Woerner likes to talk about what he calls "Space 4.0".  This is the new era of space endeavour following astronomy (1.0), Apollo (2.0) and the ISS project (3.0).
Space 4.0 is all about day-to-day business, interactions with society in general, and the commercialisation of all areas of activity.  And that, Mr Woerner believes, requires new roles and new relationships for the traditional space actors like Esa.
He has talked of making Esa more transparent and approachable. He wants to see "Jam sessions" that would open up agency policy to outside suggestions.
"We would like to have people from very different backgrounds - not just the people baptised with the water of space, but also people from other areas, because space nowadays is in everyone’s hands, in their homes.
"And after eight years at the top of DLR, I know that people are really interested in space. And I think we can get from them a lot of good ideas and visions on what to do, and where the priorities should be, because money is always limited."
Mr Woerner has written a blog to mark his first day in office.

Two men arrested after a march organised by the English Defence league (EDL) in Nottingham, have been charged.

Carl Worrall, 49, of Pyle Street, Newport, Isle of Wight is accused of a public order offence.
Jack Stevens, 26, of Oxford Street, Long Eaton, was charged with criminal damage in connection with the throwing of a flare.
Nottinghamshire police commissioner Paddy Tipping said the cost of policing the march will probably reach Â£200,000.
About 100 EDL supporters attended, with several hundred people gathering to oppose the protest.
Mr Tipping said he will be asking the Home Office to introduce tougher laws to stop disruptive protests.
"We have to be clear that demonstrations like this are disruptive and they do cause concern in the wider community," he said.
"I am not sure we have got the balance right. People have a right to demonstrate but normal citizens have a right not to have their lives disrupted."
Police said of four other people arrested in connection with the demonstration, one was bailed and the other three released without charge.
They said they had received no reports of injury or assault during the march.
The force was supported by 21 other police forces - including specialist officers, police dogs and mounted officers.


A man who was abandoned in a cinema toilet cubicle 61 years ago has met his Scottish half-brothers and sister for the first time.

Robert Weston was found in the ladies toilet at an Odeon cinema in Birmingham in March 1956.
He has never managed to track down his mother but a DNA database helped him to find his late father's other children, who live in north east Scotland.
Robert discovered he has at least four surviving brothers and a sister.
He told BBC Scotland it had been "extremely surreal" to discover he had a long-lost family in Scotland and to speak to his half-brother Tommy Chalmers on the phone.
He says meeting them for the first time was the "most profound experience".
Robert met Tommy and half-sister Pat McBain at Inverness airport earlier this month.
He says: "I arrived at the airport and I was really nervous.
"I spotted them and I felt my face break into a huge grin. I just had to touch them to make it real."
Tommy, who lives at Burghead in Moray, and Pat, who lives in Banff, took their new brother to meet other relatives, including another brother in Turriff, where their father had lived most of his life.
Tommy's father, Charlie Chalmers, had three young sons with his wife in Aberdeenshire before he went to work in the English Midlands in the early 1950s.
He appears to have had at least one child with Robert's mother, probably living in Rugby or Leicester, before returning to his wife and having three more children.
Tommy says there is an eight-year age gap between his older brothers and him, the eldest of the second set of siblings.
However, he says his father's movements were never discussed in the family.
Tommy says: "We sort of suspected something like this over the years.
"There have been one or two things that have cropped up, little things spoken about in the family, but I don't think anybody was 100% sure."
Robert and Tommy's father died in 1996.
Tommy says that a letter was found soon after which could have shed light on the identity of Robert's mother.
"I have never seen this letter, however, my sister has and a few others have," Tommy says.
"It was a letter from Rob's mum in 1956 to my father saying that she could not afford to keep the two kids.
"And there was mention of a name, Laurie, and we are not sure if that is male or female or if it is Rob's real name.
"However, this letter has either been mislaid or has gone missing.
"If we could find that, we could have a clue to finding Rob's mother."
Robert has no other clue to her identity.
When he was found, at just three weeks old, there was only a brief description of a woman in her mid-20s seen holding a baby in the cinema foyer.
Robert, who has recently retired from being a lecturer and lives in Plymouth, has been searching for her for 46 years.
In 2006, a documentary about his quest led to a reunion with Mavis Smith, the 17-year-old girl who had discovered him while she was on a date with her boyfriend.
It was not until Robert's eldest daughter started a Facebook appeal to find her father's family that they got involved with DNA detective Julia Bell.
Tommy's second cousin, who was researching her own family history, came up with a close DNA match on one of the genealogy databases.
Ms Bell persuaded her mother, Tommy's cousin, to do a DNA test and the results showed they were getting closer.
All the cousin's uncles were "long dead" so she asked Tommy to take the DNA test and it came up 100% positive.
Robert says he had already been told that his DNA profile suggested he was Scottish but he was "shocked" to finally find and speak to Tommy.
"It was a surreal moment," he says.
"I have this guy on the other end of the line, speaking in a Doric accent, who is actually my brother."
Robert says he and Tommy have lived "parallel lives", sharing many of the same interests and experiences such as time at sea.
Tommy, who is 58, told BBC Scotland: "We get along really well.
"We share a lot of things in common and Rob's the double of my father."
Robert, who is a father of six himself, says all the relatives remarked on the "uncanny" resemblance to Charlie.
He says he visited the grave of his late father in Turriff and said: "I bet you didn't expect to see me here."
Robert spent the first seven years of his life in a children's home in Droitwich, before he was adopted by a couple who ran a pub.
It was his first experience of family life and he found it hard to settle in initially, but things got much better and he describes them as "wonderful".
He now says: "As a boy I was confused and angry. I grew up with a lot of pain and despair for many years.
"I blamed my dad and mum but then over time you come to look at the world in a different way."
Robert says he now bears no animosity to his father and just wishes to know what happened and perhaps locate his mother or the second child which is thought to have been referred to in the lost letter.
He says: "There could be somebody else out there who is part of this story and I'd love to meet them."


A stretch of the A7 through Hawick is to close for three weeks during part of the town's flood protection works.

The section of Commercial Road between North Bridge roundabout and Bruce Motors will close from Wednesday.
It will allow checks to be carried out on the suitability of the road structure for flood defences in the area.
All businesses in the area will still be accessible to members of the public via a signed diversion route.
Scottish Borders Council said a range of options had been considered - including the use of traffic lights - but that could have extended the works to 10 weeks.
Councillor Gordon Edgar said: "The council realises this will be a major inconvenience to some people in the town and beyond but these works are vital to taking the Hawick flood protection scheme forward.
"The project team need to know the current condition of the road structure in order to take forward suitable flood defences for this part of Hawick, which has previously been badly hit by flooding from the nearby River Teviot.
"The project team, SBC roads department and Transport Scotland will monitor the closure throughout its duration to ensure the diversion route is working safely and effectively."


The Egyptian authorities have seized 9,000 tonnes (9,920 tons) of sugar in raids on factories and warehouses, amid a nationwide shortage of the commodity.

Prime Minister Sherif Ismail said the raids had had a "positive impact" on supplies, meaning there would now be enough to cover the next three months.
The sugar will be resold at subsidized prices through state-run outlets.
Sugar has all but disappeared from supermarket shelves in recent weeks, prompting widespread anger.
This crisis comes as President Abdul Fattah al-Sisi's government makes unpopular cuts to a costly subsidies programme and attempts to finalise a $12bn (Â£10bn) International Monetary Fund loan it sees as key to reviving the struggling economy.
A dearth of foreign currency and a sudden suspension of oil aid from Saudi Arabia have also led to the value of the Egyptian pound plummeting on the black market.
Edita Food Industries, one of Egypt's largest confectionary makers, told the Reuters news agency on Monday that its factory in Beni Suef province had been shut for three days after officials seized about 2,000 tonnes of sugar.
The company stressed that it had not been overstocking sugar, and that the sugar had been obtained legally from the private sector and not the black market.
In an interview with Egypt's CBC TV, Mr Ismail said: "There are some negative points that we are dealing with but they were a limited number of cases."
"We can't leave the market without supervision," he added. "Monitoring is necessary."
However, the Federation of Egyptian Chambers of Commerce warned that the seizure of commodities from the private sector would result in more shortages, as companies would be "forced to exit the market instead of expanding and investing".
"If the government has a problem, they should come and negotiate, but this way of seizing stocks and treating us as smugglers is shameful," Edita Chairman Hani Berzi told CBC.
Egypt imports almost a third of the 3m tonnes of sugar it consumes annually.
The sugar shortage had led to prices almost doubling to 10 Egyptian pounds ($1.13) per kilogram in the past few weeks, according to supermarkets surveyed by Bloomberg.
Earlier this month, the state-run al-Ahram newspaper reported that a government hotline had been set up to report hoarders, and that a man who works as a waiter at a cafe had been arrested for possession of 10kg (22lb) of sugar, deemed to be in excess of the amount reasonable for personal use.


A former soldier who was jailed for life for murdering Greenock teenager Elaine Doyle 30 years ago has lost an appeal against his conviction.

John Docherty, 51, from Dunoon, Argyll, was convicted in June 2014 and jailed for a minimum term of 21 years.
Judges have also rejected an appeal that the minimum term was excessive.
The body of 16-year-old Elaine was found in a lane close to her parents' flat in Greenock in 1986. Docherty's DNA was later identified on her body.
Rejecting Docherty's appeal, Scotland's senior judge, the Lord Justice General, Lord Carloway, said: "This was a compelling circumstantial case and the appeal against conviction is refused.
"This was a murder of an innocent 16-year-old girl making her way home along the public streets after a night out in central Greenock. It is a crime of rare callousness and brutality.
"As the trial judge records, it caused widespread public revulsion and anxiety and terrible anguish for the deceased's family over many years."
Lord Carloway added: "Although the fact that the appellant was in his early 20s when he committed the crime, and is now 51, is a matter to be taken into account, a significant punishment part was inevitable notwithstanding the appellant's unblemished record since joining the army in the year after the crime."
The former soldier was arrested in 2012 following a cold case review and found guilty of murdering Elaine as she walked home from a disco in Greenock's Celtic Supporters' Club.
Detectives arrested Docherty, of Dunoon, Argyll, after his DNA was found on sticky tape used in 1986 to lift hairs and fibres off Elaine's body,
The techniques required to match DNA were not available at the time of Elaine's death but cold case detectives reviewed thousands of statements and discovered Docherty had not been questioned after the murder.
When he was asked for a DNA sample, Docherty agreed and appeared "stunned" when he was later charged with Elaine's murder.
During his trial, it emerged Docherty, then 21, and a friend, had been at the Celtic Supporters' Club, and while the friend was interviewed and named Docherty as being with him, officers never approached him.
The ex-Royal Engineer, who moved back to Greenock after leaving the Army, was one of 722 potential suspects and he was tested in May 2012.
Docherty denied murder and did not give evidence in his defence and his QC, Donald Findlay, branded the investigation "a shambles", after hearing a blanket from a police car was draped over Elaine.
He claimed the crime scene had been contaminated and the DNA evidence was not reliable.
But the jury disagreed and found Docherty guilty.


The button from a plane used to release a "bouncing bomb" that destroyed a key dam during World War Two is to be auctioned.

The mission involving the Lancaster Bomber from 617 Squadron was later immortalised in The Dambusters film.
Its bombs destroyed the Möhne Dam in Germany on 17 May 1943.
Northamptonshire auctioneers said it was expecting the Bakelite button to fetch between £25,000 and £40,000 when it goes on sale at the weekend.
The bombs caused catastrophic flooding of the Ruhr Valley, playing a role in "almost certainly shortening the war," according to Jonathan Humbert, of J P Humbert Auctioneers.
According to Mr Humbert, the button was pressed by Pilot Officer John Fort on board Lancaster bomber ED 906 AJ-J, which was piloted David Maltby and was the fifth aircraft to attack the Mohne Dam.
Squadron Leader David Maltby, gave the button and other items from the plane to the Hydneye House school museum where his father was headmaster.
When the school closed a former pupil acquired the historic items.
They included four large marbles used by bouncing bomb inventor Barnes Wallis in the development of his weapon.
The marbles and an altimeter especially fitted at eye level to bomber ED932 AJ-G piloted by Guy Gibson to aid in low-level flying on approach to the doomed Möhne Dam will also be auctioned, together with a cockpit blackout blind from Gibson's plane.
Mr Humbert said: "These are incredibly rare and very historic items of a simply unrepeatable nature. I anticipate global interest in these evocative and iconic pieces of 20th century British history."


A man has been hit and killed by a train at a railway station near Birmingham.

British Transport Police (BTP) said it was called to Marston Green station at 16:59 BST to reports of a person being struck by a train.
Paramedics attended but the man was pronounced dead at the scene.
Services have been cancelled and delayed and travellers were warned of ongoing delays and disruption to their journey until at least 22:00.
The 16:50 Birmingham New Street to London Euston service was involved in the fatality, a spokesman for BTP said.
The death was not believed to be suspicious, he added.
Virgin Trains, Arriva Trains Wales, CrossCountry and London Midland services were affected as result.


Will Eastern Europe squander its historic opportunity to provide the next United Nations secretary-general, when Ban Ki-Moon's tenure expires at the end of this year?

Under an informal rotating principle, the ninth secretary general should be an Eastern European. But the region risks losing that chance because of lukewarm backing for national candidates at home, and a regional failure to pull together to back one individual.
An informal selection procedure, made more transparent this year by open hearings, has produced 11 candidates so far, eight of them from Eastern Europe.
The former or current foreign ministers of Moldova, Macedonia, Montenegro, Croatia, Serbia and Slovakia, plus the former president of Slovenia are all in the race.
Bulgaria has proposed Irina Bokova, current head of Unesco, the cultural and educational wing of the UN.
The other New York race
Helen Clark to run for UN top job
Close observers at the UN say the candidates risk crowding each other out - leaving the way open for other strong candidates including Susana Malcorra of Argentina, Helen Clark from New Zealand, or the tough-talking former UNHCR head, Antonio Guterres from Portugal.
In July, a straw poll among the 15 members of the Security Council should give a clearer idea of the backing, or lack of support, for each.
Even more candidates could also step forward in the coming weeks. Another Bulgarian stateswoman, Kristalena Georgieva, is widely rumoured to be on the brink of announcing her candidacy.
"I am obviously watching the race closely. A lot of people are urging me to enter. Let's see what happens," she told the BBC. Behind the scenes, several countries are said to be considering nominating her.
Ms Bokova was an early frontrunner, and enjoyed crucial Russian backing. But her chances have been harmed by a damning investigation of the inner workings of Unesco in recent months, and by her support for Palestinian statehood - frowned on by the US government.
Nearly half of Unesco's budget currently goes on staff salaries.
By way of contrast, Ms Georgieva has a strong record as an administrator at the World Bank, and as a former EU commissioner for humanitarian affairs and current commissioner for budgetary affairs.
In recent months, she led the team overseeing a new blueprint for UN humanitarian interventions which concluded that $1bn (Â£710m) a year could be saved by directing funds directly to those in need.
More information on the candidates and the selection procedure is available on the UN's website
"Insiders say that either Kristalena Georgieva or Antonio Guterres could give the UN the kind of kick up the backside it needs," said Richard Gowan, a UN expert at the European Council on Foreign Relations.
There is a consensus that the next leader of the UN should be a good manager with experience of running international organisations. Wide international backing for the idea that the next UN secretary-general should be a woman, plus Russian insistence that she or he speak Russian, could tilt the race into a battle between the two Bulgarians.
"This is such a loose process, that if it became clear that Ms Georgieva had the support of the five permanent members, there is a way to get her back into the running," said Richard Gowan.
A final decision on the next secretary-general is expected in October, when Russia presides over the Security Council.


Annual reading and numeracy tests for children aged from six to 14 will be taken online from September next year, the Welsh Government has said.

Paper tests are being replaced with personalised online assessments which adapt to pupils' skills, providing an appropriate level of challenge.
Liberal Democrat education secretary Kirsty Williams said it will benefit pupils, parents and teachers.
Plaid Cymru and the Welsh Conservatives both warned of "potential pitfalls".
UKIP has been asked to comment.
Since 2013, all pupils in Wales in years 2-9 sit an annual reading and numeracy test, which ministers say help teachers monitor progress and identify where help is needed.
According to the Welsh Government, the advantages of testing online are:
The tests have been specifically designed for use in Wales and will be phased in over three years, starting from the 2018-19 academic year.
Education Secretary Ms Williams, who sits in the Labour-led cabinet, said: "These tests are about raising standards by showing the next steps that children need to take in their learning.
"Pupils will be taking assessments that will adapt to their needs and skills. They will have the benefits of automatic marking and schools will have feedback faster than before, giving them a better picture of how they can help all their learners to move on."
Plaid Cymru shadow education secretary, Llyr Gruffydd, said teacher assessments "provide a much more-meaningful overview of pupil achievement than crude testing".
"It's teachers who are best placed to understand the progress and needs of individual pupils," he said.
"If the Welsh Government is to persist with testing, however, anything that reduces bureaucracy should be welcomed in principle but assurances need to be given that online assessments will not weaken the focus on the individual."
Mr Gruffydd added there were also "potential pitfalls" in dealing with poor broadband access in certain parts of the country.
Welsh Conservative AM Darren Millar said the tests represented a "welcome opportunity" to measure pupil progress and allow performance comparisons between and within schools.
But he said it "conveniently ignores the unacceptable fact that hundreds of children across Wales are still at an educational disadvantage because of inadequate broadband connectivity both at home and in school".
He said the Welsh Government "must take urgent steps to redress this if they are to successfully roll-out the new testing regime".
UKIP education spokeswoman Michelle Brown said: "Over the years, the government have failed to attract people to come and teach in Wales, so they are now having to move towards 'robotic' classrooms, where computers are taking the place of teaching staff.
"Education standards have continually worsened under Labour, and if I were the education minister I would concentrate more on getting the teaching side right in the first place, before trying to automate the way children are tested."


Scotland's top law officer has said it was the "right decision" not to prosecute driver Harry Clarke over the Glasgow bin lorry crash.

Lord Advocate Frank Mulholland said there was "insufficient evidence in law" to bring proceedings.
Mr Mulholland defended the speed with which the Crown Office made the decision not prosecute the driver.
He said no evidence had been heard at the inquiry into the crash that the Crown did not know at the time.
A fatal accident inquiry (FAI), which has been running for five weeks, heard that 58-year-old Mr Clarke was unconscious at the wheel when the Glasgow City Council bin lorry veered out of control in Queen Street on 22 December last year.
It also heard allegations Mr Clarke lied about his medical history to doctors, the DVLA and his employer.
Before it crashed into the side of the Millennium Hotel in George Square, the lorry had killed six people and injured 15 others.
The families of some of the victims said Mr Clarke should face criminal charges for his actions and they intend to bring a private prosecution.
The lord advocate, in whose name all prosecutions on indictment are conducted, told BBC Scotland that private prosecutions were "very rare".
He said no court would grant authority for a private prosecution unless there was sufficient evidence in law.
"The view that Crown Counsel took in this matter, together with all the people working on the case, was that there was insufficient evidence in law," he said.
Mr Mulholland said he understood the "anger and upset" of the families of the victims that no-one had been found criminally responsible for the deaths.
He said there was no dispute that Mr Clarke had been unconscious at the wheel of the bin lorry and as such he did not have the required "criminal intention".
The chief prosecutor said it would be necessary to demonstrate "forseeability".
"In other words, Mr Clarke, as a result of his ongoing medical condition, must know that he was unfit to drive on that day," the lord advocate said.
"That is what the Crown requires to prove."
The law officer said that since the blackout when he was a bus driver in 2010, Mr Clarke had experienced no other episodes for a period of four-and-a-half years.
He said that during that period, Mr Clarke was a professional driver for both First Bus and Glasgow City Council, driving PSV vehicles, gritting lorries, minibuses and bin lorries, without any episodes.
The lord advocate said Crown Counsel took this into account as well as a number of other factors.
He said: "Firstly no doctor had told Mr Clarke he was unfit to drive. In fact no doctor had told him he should notify the DVLA about his 2010 episode.
"If he had notified the DVLA about his 2010 episode, the worst that could have happened to Mr Clarke would have been that his licence was suspended for 12 months maximum and if there was no cause for concern his licence would have been returned to him.
"When he moved from First Bus to Glasgow Council, he got an acceptable reference and the occupational doctor for First Bus reviewed him.
"He was well aware of the 2010 incident, and he concluded he was fit to drive and didn't need to notify the DVLA.
"And it is noteworthy that following the events of December 2014, the DVLA were notified; full details of the George Square incident together with the 2010 incident, and as a result of DVLA procedures, his licence was returned to him.
"So if you put all that evidence together you cannot conclude in law that Mr Clarke knew or must have known he was medically unfit to drive that day."
Mr Mulholland said that was supported by colleagues of Mr Clarke, who gave evidence there were no warning signs whatsoever.
Mr Mulholland added: "The FAI is different than a criminal trial. It is there to establish causes of death then look at what recommendations can be made by the sheriff to prevent such a tragedy happening again.
"A criminal trial is different. It looks at the issue of guilt or innocence in relation to charges brought.
"No proceedings were brought against Mr Clarke. That was the right decision. It was the only decision that can be made because there is insufficient evidence in law."
The lord advocate said that to bring a case to court without sufficient evidence would be "an abuse of process" and would cause a lack of confidence in the system.
He said: "We have to take hard decisions on a cold, hard analysis of the evidence and in this case there is insufficient evidence in law to prosecute Mr Clarke."
Mr Mulholland said the decision not to prosecute was taken by a senior member of the Crown counsel cadre and he supported it.
He also rejected criticism that the decision not to charge Mr Clarke, taken within nine weeks of the tragedy, was too quick.
He said there was a "thorough and complete investigation" but it was in the public interest to move quickly because people wanted answers.
The lord advocate said there were no barriers to making the decision - unlike in the case of the Clutha helicopter disaster, which took place a year earlier but which is still waiting for the results of an Air Accidents Investigation Branch inquiry.
He added: "There is no evidence which has come out at the Fatal Accident Inquiry which the Crown were not aware of at the time the major decisions were taken."


Wales should cash in on the higher profile the European Championships has given the country, First Minister Carwyn Jones has said.

Wales finished their first major tournament in 58 years at the semi-finials of the European Championships, losing 2-0 to Portugal on Wednesday.
Mr Jones said the "big change" was that people in continental Europe no longer do not know where Wales is.
The years of having to explain Wales is not in England have ended, he said.
Mr Jones, who was speaking on BBC Radio's Good Morning Wales programme, said: "The big change is instead of people saying in Europe 'Wales where's that?'
"It's going to be 'Wales, oh yes, we know where that is, the semi-finalists of the European Championships'.
"When I was in Paris last night, I didn't get to the game but I watched the game in Paris, all people could talk about was Wales.
"I was hearing people talking about Wales on the streets. The sort of profile that it's given us has been incredible.
"We've really got to cash in on this now.
"All those years when you go abroad and you have to explain where Wales is, that it wasn't part of England. In the space of a month, five weeks, all of that has turned on its head."


The US and Cuba have struck a prisoner swap deal that involves the release of American Alan Gross and three Cubans, US officials have announced.

Mr Gross, 65, has spent five years behind bars after being accused of subversion on the communist island.
He left Cuba on a US government plane and was freed on humanitarian grounds, a US official told Associated Press.
His arrest and imprisonment has undermined attempts to thaw diplomatic relations between the two countries.
American officials told Associated Press the two countries will start talks to normalise relations and the US is looking to open an embassy in Havana in the coming months.
The three Cubans released in the US are part of the so-called Cuban Five convicted of spying.
Prosecutors said the five had sought to infiltrate US military bases and spied on Cuban exiles in Florida.
Two were recently allowed to return to Cuba after finishing their sentences.
Mr Gross, who has been in declining health, was jailed for 15 years for committing "acts against the integrity of the state".
His work in building internet access for local communities involved bringing in satellite equipment that is illegal in Cuba.
The Cuban authorities saw his activities as a covert attempt at regime change, although Washington protested his innocence.
This week, former US President Bill Clinton accused Cuba of playing a "very dangerous game to hold Gross where his health is getting worse".

The body of Manx soldier Billy Redmayne will be taken on a lap of the Isle of Man TT course ahead of his funeral later this month, it is announced.

The 25-year-old from Laxey died in hospital on 19 April after sustaining serious head injuries during a crash at the Oliver's Mount Spring Cup.
An escorted lap of the Mountain Course will depart from the TT Grandstand at 12:00 BST on 13 May.
His family said well wishers are invited to take part in the procession.
Redmayne was a serving member of the Parachute Regiment who had served three tours of Afghanistan.
He will receive a military funeral at Douglas Crematorium.
The Laxey racer won the Junior Manx Grand Prix in 2015 and was regarded as one of the brightest prospects in the sport.
He had been set to make his debut at both the North West 200 and Isle of Man TT races this summer.


(Close): Shares in BG Group soared 26.65% after it backed a £47bn takeover by oil giant Royal Dutch Shell.

BG shares were up 242.60p to 1,153p after it agreed to a cash and shares offer from Shell that would value each BG share at about 1,350p.
Royal Dutch Shell 'A' shares fell 5.3% while Royal Dutch Shell 'B' shares dropped 8.6%.
The FTSE 100 fell 24.36 points to 6,937.41, but energy shares saw gains in the wake of the deal.
BP shares rose 0.5%, Ophir Energy climbed 7.4% and Tullow Oil jumped 4.4%.
"Already the largest FTSE 100 constituent by a considerable margin, this deal will further consolidate Shell's position in that regard," said Richard Hunter at Hargreaves Lansdown Stockbrokers.
"There are clear attractions from Shell's viewpoint, including its additional exposure to LNG, almost immediate cost synergies and, in due course, asset sales from a partial break up of BG's operations."
Shares in satellite broadcaster Sky rose 1.6% following reports that French media group Vivendi was mulling a possible bid for the firm.
The Reuters news agency cited three unnamed sources familiar with the matter as saying a bid for Sky was one of a number of options being looked at to expand Vivendi's TV group Canal Plus.
On the currency markets, the pound rose 0.78% against the dollar to $1.4925 and was up 0.76% against the euro to €1.3799.


Oil exploration firm Hurricane Energy has tripled its estimate of recoverable oil from its Lancaster field in the North Sea.

The AIM-listed company said it had raised its recoverable resource estimate for the field from 200 million in a 2013 assessment to 593 million barrels.
Output from Lancaster is expected to start in the first half of 2019.
A daily production rate of 17,000 barrels is expected soon after that.
Last week Hurricane announced that it had made the "largest undeveloped discovery" of oil in UK waters.
The company said one billion barrels of recoverable oil could be contained within the Greater Lancaster Area, 60 miles (97km) west of Shetland.


Secondary ticketing websites are enabling professional touts with "preferential schemes" for power sellers, MPs have been told.

Ticket fraud expert Reg Walker claimed that some sellers were paid in advance, and given powerful software to manage their inventories.
He said sites were dependent on "bad actors" who used computers to harvest "and resell high volumes of tickets".
"Secondary sellers are covering [for touts] in some cases," he added.
Mr Walker is head of the Iridium Consultancy, which tackles ticket fraud for a number of major UK venues, including London's O2 Arena.
Speaking to MPs on the Culture, Media and Sport select committee, he said that some sellers were "courted" by sites like GetMeIn, Viagogo and Stubhub.
"And the reason is there's a finite amount of these people that harvest tickets in bulk."
Stubhub, which is owned by eBay, also gave evidence, and insisted that they carried out "due diligence on all our sellers".
However, "we do not police or monitor our site and we are not required to do so", said Paul Peake, head of the company's legal department.
You Me At Six singer Josh Franceschi was among those calling on MPs to clamp down on online ticket touts.
The 26-year-old said computer programmes known as bots, which bulk-buy tickets the second they go on sale, should be made illegal.
Those tickets often ended up being sold at inflated prices on the secondary market, he added.
"Money is been taken out of the industry and put into the hands of people who are only concerned with lining their own pockets.
"The main losers here are the fans of live music."
However, Mr Walker revealed that it is not just professional touts who exploit the system.
He said tickets for a recent Michael Buble tour had been handed directly to secondary ticketing websites by one of the star's associates.
"I believe that was done without the artist's knowledge," he said, "but it makes me wonder if there are other artists that this is happening to."
Arctic Monkeys' manager Ian McAndrew said he had been offered similar deals in the past.
"I have often been approached by one of the big four resale sites asking to enter into an arrangement where I give them inventory in return for participation in the resale profit," he told MPs.
"That is a proposal I've refused on a number of occasions - but I can understand how that would be a temptation for some who want to maximise profits for a show."
Mr McAndrew also called for greater transparency from primary sellers. He said it is often "unclear" how many tickets will be available when a tour goes on sale - as venues, promoters, bands and sponsors often receive their own allocation to distribute separately via pre-sales and promotions.
"The number of tickets that then go on sale at general sale is unknown, is unclear to us. But there is increasing evidence to suggest it is far smaller than it should be."
A limited supply of tickets helped fuel the secondary market, he said.
Chris Edmonds, Chairman of Ticketmaster UK, confirmed that up to 50% of tickets could already have been allocated when the general sale begins.
"We can have hundreds of thousands of consumers queuing on our site to buy tickets for an event, with no real visibility of how many tickets are left," he said.
"Wherever you have an instance where demand is beyond supply, it creates a concern and a frustration and a disappointment."
A government review of the ticketing market was conducted earlier this year by Professor Michael Waterson, economics professor at Warwick University.
Speaking on Tuesday, he said he was not in favour of banning the secondary ticketing market, but supported the idea of outlawing "bots".
He also called for pop concerts to introduce variable pricing - as seen in opera and theatre - in an effort to deter touts.
Labour MP Sharon Hodgson, co-chair of the all-party parliamentary group on ticket abuse, told the BBC: "Fans cannot be fleeced any longer.
"I hope the government will realise that sitting on their hands cannot go on and will listen to the chorus of concerns coming from the industry, fans and Parliamentarians and finally take action."

The RAF Tornado mission against Islamic State militants in Iraq is to be extended by an extra year, Defence Secretary Michael Fallon has said.

The jets - due to be disbanded last March - are to be kept in service until "at least" March 2017 to continue air strikes, he said on a visit to Iraq.
Mr Fallon said the air campaign against the IS group was making progress.
UK jets had pushed militants out of key towns and would maintain "essential precision firepower," he said.
Tornados began carrying out missions in Iraq last September as part of US-led air strikes against IS, an extremist group which has seized control of parts of Iraq and Syria.
The squadron of Tornado GR4 fighter bombers - Number 12 Squadron - was due to be disbanded last year and replaced with a squadron of Typhoon air defence fighters.
But, following initial air strikes, Prime Minister David Cameron announced the Tornados would continue in their specialist ground-attack role until March 2016.
Mr Fallon said this second reprieve for the eight bombers - which are based in Cyprus - would ensure the RAF retained "the essential precision firepower, intelligence and surveillance" capabilities needed for operations against IS, also known as Isil.
He denied the extension had come about because there were no other RAF aircraft capable of flying the missions.
Tornados had "proved their worth" in Iraq, he told the BBC, adding they had completed about 30% of the coalition's surveillance missions, as well as carrying out air strikes.
BBC security correspondent Frank Gardner
The announcement on Britain's ageing but effective squadron of RAF Tornado bombers has been carefully planned.
Mr Fallon announced it in Baghdad, from where he is keen to give the message that slowly but surely Iraqi forces are starting to push back the jihadists and retake territory.
He denied that Britain's contribution - of under 5% of the coalition's air strikes - was making only a negligible difference. He said the Tornados' combination of precision-guided weapons and hi-tech surveillance pods made them vital.
The painful truth for the coalition though is that for more than a year now IS has been able to hold on to most of the huge areas it has occupied in Iraq and Syria, something al-Qaeda never achieved.
It is earning estimated oil revenues of $40m a month and replenishing its ranks of recruits faster than they are being killed off.
This, admitted the defence secretary, will be a long fight.
Jonathan Beale: The UK's gap between rhetoric and reality
Speaking earlier in Baghdad, where he met Iraqi officials, he said Iraq needed British help with air support, training and equipment, but not with ground troops.
"RAF Tornados have carried out hundreds of strikes, helping Iraqi forces push back Isil from the Kurdish region and out of key towns such as Tikrit and Bayji," he said.
"We want to ensure we maintain this crucial operational tempo and so we will extend the lifetime of Number 12 Squadron for a further year to March 2017."

The GR4s operating out of Cyprus are equipped with precision-guided Paveway bombs and Brimstone missiles.
They can also be fitted with Raptor reconnaissance pods for carrying out surveillance and intelligence-gathering missions.
Together with the RAF's unmanned Reaper drones they have flown more than 1,100 combat missions over Iraq and carried out more than 250 air strikes.
They have also carried out surveillance missions over Syria but Parliament has not approved air strikes there.


Broadcasting executives are gathering in Edinburgh for the start of the annual international television festival.

The keynote MacTaggart Lecture will be given by the director general of the BBC, Mark Thompson, at what is a crucial time for the corporation.
Last year during the keynote Edinburgh speech, one of the BBC's biggest competitors, James Murdoch, launched an outspoken attack on the corporation.
He called its "dominant" scale "chilling" and said that it should be "far, far smaller".
The BSkyB chairman - who also runs much of News Corporation, the publisher of The Times, Sunday Times, Sun and the News of the World - expressed particular concern over the public funding of the BBC's news output, which he called "state-sponsored journalism".
He claimed it was a "threat to the plurality and independence of news provision", because it made it hard for commercial publishers to earn money from their own news websites.
To some of his audience, the idea of "state-sponsored journalism" was over the top.
But, worryingly for the BBC, Murdoch's general point that the corporation was too big and was harming its commercial rivals, drew murmurs of agreement from other media owners and politicians.
Since then, the BBC has found itself under almost constant fire, not least in the newspapers which now compete with it, as they extend their businesses onto the internet.
In this year's MacTaggart Lecture, Mr Thompson must try to win round the corporation's critics, including some of those commercial rivals and politicians.
But he must also set out his vision for the BBC, as a publicly-funded news and cultural organisation in a world of rapidly changing technology and behaviour - and tighter public finances.
The BBC has been widely criticised for the large sums of licence fee money it pays to its stars and top managers.
In the new age of public austerity, Culture Secretary Jeremy Hunt says much needs changing at the BBC.
He has given notice that the next licence fee negotiations - when they begin in a year's time - will be very tough.
Viewers, he says, can expect to pay less.
Belatedly, the BBC has responded to some of the criticisms.
Senior executives' pay has been published, then frozen, and bonuses withdrawn.
The highest-paid managers are giving up a month's pay for the next two years and will be asked to withdraw from a scheme which tops up their pensions.
The BBC is to publish the names of its highest-paid presenters and performers and it has proposed radical cuts to its staff pension scheme, to cope with a large deficit.
But that in turn has alienated many BBC employees, who are less highly paid.
Unions are balloting their members for strike action.
Other staff are unhappy because their jobs are moving to the north of England, while executives leading the move are keeping their own homes in the south.
Mark Thompson must address all of these different concerns and audiences.
Yet he is also expected to point out that the BBC has much to be proud of.
It still has high support from the public, and large and appreciative audiences for its television, radio and online services.
Innovations such as the BBC website and iPlayer have added to the public benefit provided by the corporation in recent years.
When, asked to make cuts, it tries to close a service such as the digital radio station 6 Music, there is an outcry.
On the eve of Mr Thompson's speech, the case for the BBC has been eloquently argued by two academics in what they call An Appeal to the New Parliament in Defence of a British Institution.
Professor Steven Barnett and Professor Jean Seaton, of the University of Westminster, call on Parliament to remember "the huge affection in which the BBC is held by the British public, the worldwide admiration which it attracts, and the immeasurable importance of the democratic and cultural contribution which it makes to British life".
The BBC director general could hardly put it better himself. Whether he does so remains to be seen.


Emre Can has played down the apparent elbow from Marouane Fellaini during Liverpool's 2-0 Europa League last-16 win over Manchester United on Thursday.

United midfielder Fellaini appeared to catch Can with an arm during Thursday's first leg at Anfield and could face retrospective punishment from Uefa.
But 22-year-old Can said: "Fellaini is a fair sportsman. He touched my throat with his elbow but it is OK.
"It was just a small fight. It was not a boxing ring punch."
Spanish referee Carlos Velasco Carballo produced six bookings in the game, but did not produce a card for Belgian midfielder Fellaini for the clash with Can.
Liverpool dominated Thursday's game and won it through a Daniel Sturridge penalty and second-half goal from Roberto Firmino.
The home side could have had a bigger lead to take to Old Trafford for next Thursday's second leg were it not for United keeper David De Gea, who made a number of good saves.
"De Gea is a very good goalkeeper but we created chances, played well and scored two goals," added Can.
"It was incredible, a very good score for the second leg and we have to keep going like that."


A Vietnamese oil tanker which went missing last week was seized by pirates who stole some of its cargo before releasing its crew, say officials.

The MT Sunrise 689, heading to Vietnam's Quang Tri port, disappeared shortly after leaving Singapore.
The crew said about a dozen men armed with guns and knives had boarded the ship and beaten them.
They siphoned off the oil before leaving the ship and freeing the crew on Thursday morning.
"The pirates broke the communication system, robbed the oil and goods on board," Nguyen Nhat, director of Vietnam's Maritime Department, told AFP news agency.
He said the pirates had taken about a third of the cargo.
Ship captain Nguyen Quyet Thang told Vietnam's Tuoi Tre newspaper that the hijackers had pulled alongside the Sunrise in a high-speed boat and two fishing boats about two hours after they left Singapore on 2 October.
The pirates then boarded the ship and took control of the crew.
Some crew members were assaulted when they tried to resist them, he said. One had a broken toe and injured kneecap, while another had an injured ankle.
Crew members were given only a meal per day, he added.
The ship's deputy captain Pham Van Hoang said he believed the pirates were Indonesian.
"They put knives on our throats and threatened to kill us if we resist," he told the Associated Press by phone from the ship.
The MT Sunrise 689, now expected to arrive in Vietnam on Thursday evening, is the 12th tanker to be hijacked in South East Asia since April this year.
The International Maritime Bureau says there has been a steady rise in piracy across southeast Asia, particularly in the busy Malacca Strait between Singapore, Indonesia and Malaysia, despite regional efforts to tackle the problem.
Globally, piracy is estimated to cost the shipping industry as a much as $8bn (Â£5bn) a year.


People of the Commonwealth should "support those in need" and others who "feel excluded", the Queen has said.

Her annual message to the association addressed its 2016 theme - inclusivity.
The Duke of Edinburgh, Duke and Duchess of Cambridge and Prince Harry will join the Queen later for the Commonwealth Day service at Westminster Abbey.
The principal reflection will be given by former UN Secretary General Kofi Annan and there will be a performance by singer Ellie Goulding.
Other guests at the multi-faith service include outgoing Commonwealth Secretary General Kamalesh Sharma; Joseph Muscat, the prime minister of Malta, which hosted the last Commonwealth Heads of Government Meeting, and high commissioners from the association's 53 member nations.
In the evening the Queen and Prince Philip will attend a reception hosted by Mr Sharma at Marlborough House, the home of the Commonwealth Secretariat, near Buckingham Palace.
BBC iWonder - What is the point of the Commonwealth today?
Profile: The Commonwealth
In the programme for the service, the Queen - the head of the Commonwealth - wrote an essential ingredient of belonging to the Commonwealth was a "willingness to share, to exchange and to act for the common good".
"By including others, drawing on collective insights, knowledge and resources, and thinking and working together, we lay the foundations of a harmonious and progressive society."
She added: "Being inclusive and accepting diversity goes far deeper than accepting differences at face value and being tolerant.
"True celebration of the dignity of each person, and the value of their uniqueness and contribution, involves reaching out, recognising and embracing their individual identity."
The Commonwealth, a loose association of former British colonies and current dependencies, along with some countries with no historical ties to Britain, represents 2.3 billion people, of which 60% are under 30.
Members include Australia, Canada, Cyprus, Fiji, Ghana, Grenada, India, Jamaica, Malaysia, New Zealand, Nigeria, Pakistan, Singapore and South Africa.
In his Commonwealth Day message, Mr Sharma, said: "Globalisation, the digital revolution and interdependence make us both a rapidly compacting but also colliding world.
"The strengths of the Commonwealth were never needed more to assert fairness in global outcomes and trust in the richness of our human identities."


George Groves is unsure if his career would recover if he fails to land a world title at the fourth attempt.

The 29-year-old fights Russian Fedor Chudinov for the vacant WBA super-middleweight crown on Saturday.
Groves' only three defeats in his 28-fight career have come when contesting world titles.
"I know it's a long road back after a loss in a world title fight, I couldn't bear to go through that again," Groves said.
The Londoner suffered two defeats at the hands of compatriot Carl Froch before losing again to American Badou Jack in 2015.
"It's the fourth time and I can't bear to come out without the win," Groves said. "I'm a better fighter than I was in those previous attempts, better prepared. I think I've learned a lot from them and that will help me on Saturday night."
Groves noticeably ended his public workout quickly on Wednesday and he and his team swiftly left Sheffield's Peace Gardens as they focus on what appears a career-defining fight at Bramall Lane, home of the city's Sheffield United football team.
Two stoppage defeats by Froch in 2014 and a loss in Las Vegas to Jack three fights later left the Briton's career in disarray. He has rebuilt admirably having scored four wins since parting with trainer Paddy Fitzpatrick to join forces with Shane McGuigan.
Chudinov, 29, lost the WBA title to Felix Sturm last year before the German vacated the strap which will be on the line. He has had just 15 fights in eight years, 13 less than Groves who has been a professional for seven months longer.
Many commentators believe this is the best chance of Groves' nine-year career and he starts as odds-on favourite with bookmakers.
"It will mean the absolute world," added the Hammersmith fighter. "I know the pressure is on.
"We've had a great camp, I'm sure this will be my time. He's competed at the highest level but is relatively inexperienced. We may not know the best Chudinov yet."
Groves and Chudinov compete in a co-main event as Sheffield's Kell Brook also defends his IBF world welterweight title against American Errol Spence on the card.


A former US professional football player whose career was cut short by disciplinary problems has been found dead inside his California prison cell.

Officials believe Lawrence Phillips, 40, killed himself early on Wednesday.
In the 1990s, he was a star player at the University of Nebraska, making him a sought-after rookie in the NFL.
Phillips played for the St Louis Rams, Miami Dolphins and San Francisco 49ers until 1999, but he was plagued by trouble on and off the field.
After his NFL career, Phillips continued to have problems with the law.
Eventually, he was sent to prison after being convicted of assault for driving his car into a group of teenagers.
In another case, he was convicted of assaulting a former girlfriend.
Phillips, who was serving a term of more than 30 years, had been placed in a cell alone after he was accused of killing his former cellmate.
On Tuesday, a judge found that there was enough evidence to try Phillips in the death of Damion Soward, 37.
It is unclear how he took his own life.
"He was an intelligent person and had some good qualities," Tom Osborne, his coach at Nebraska, told the Associated Press news agency.
"Yet he had some anger issues and couldn't overcome the demons in his life.''


Protesting outside of Philadelphia's City Hall on the first day of the Democratic National Convention, Bernie Sanders supporters were clear - they're not giving up on their candidate or his ideas.

Many were angry and frustrated at the prospect of having to choose between Republican nominee Donald Trump and presumptive Democratic nominee Hillary Clinton. Many said they would vote for Green Party candidate Jill Stein to avoid having to vote for Mrs Clinton.
Amid chants of "Hell no Hillary" and "Feel the Bern", the Sanders faithful told us they were still fighting for Mr Sanders because politics in the US has to change, and it will not change without their efforts.
For his own part, Mr Sanders has urged his supporters to vote for Clinton, but was booed for saying so during the first day of the convention.
Sue Kirby from Massachusetts, who made a paper-mache Bernie doll herself, said Mrs Clinton is "just part of the establishment".
"She's a symbol of the people who have been running this country for the last 30 to 40 years," she said.
Asked what she would do if the ballot came down to Clinton vs Trump, she said she was "getting upset" that she keeps being asked that. In the coming days leading up to the election, she said she is going to focus on making sure her local representative in Massachusetts votes against the Trans-Pacific Partnership.
"No matter who the president is, that's going to make a difference," she said. "We've got to stick together and keep building our network."
Corey Smith from Colorado said he is dissatisfied with both Mrs Clinton and the Democratic Party.
"From the beginning we thought it was unfair… I don't want to vote for a candidate that doesn't listen to the people's interests," he said, and that the recent Wikileaks hack of Democratic National Committee emails showing favouritism to Mrs Clinton proved his suspicions that the nomination was rigged.
He still holds out hope for a contested convention, but faced with a Clinton vs Trump ballot, he said he will not vote for either of them.
"A vote for Hillary is a vote for Trump and a vote for Trump is a vote for Trump," he said.
"I'm not going to pick between the lesser of two evils… With Trump, there are a lot of bad things that can happen with his presidency, but her record shows that she's already done bad things, so it's kind of picking between somebody who has done them and somebody who might do them."

Ten-year-old Max Inoue from New York, who's following a political campaign for the first time, said he's in Philadelphia to support Bernie Sanders "because he needs us".
"I support him because he knows what's right and wrong, and Hillary Clinton and Donald Trump don't," he said. The two of them are "just as bad" as one another, he added.
"She supports [the Trans-Pacific partnership] and the Iraq War, and she also lies all the time," he said.
Max's mother Mari said she would vote for Green party candidate Jill Stein, but she is still hoping there is a way Mr Sanders can run.
Of Mrs Clinton, Mrs Inoue said: "She supports war and we should not continue to support perpetual war.
"We should be investing in education and infrastructure, and healthcare."
"We're here to support Bernie Sanders and show the DNC we know what they have been up to," said Taylor Baker of West Virginia.
She said it is "absolutely not fair" that Mrs Clinton was able to "rig herself in as the nominee" and it makes her feel like her vote does not matter.
"As long as she has the election rigged, there's no democracy in that, no America in that."
Ms Baker said she does not like Mrs Clinton because she's a "fake feminist" and a "liar".
Mr Camacho (pictured left) said Sanders supporters would not be to blame if Mr Trump wins the presidency.
"Hillary became the nominee with the DNC helping her the whole time, so I don't think she needs our help," he said.
"It's just a matter of finally feeling like we're being heard, and I don't think anybody here feels like anybody is listening to us."
Ms Baker agreed: "We shouldn't be fear-mongered into voting for somebody that's equally as horrible."


Robert Lewandowski scored twice in the last 20 minutes as Bayern Munich beat Werder Bremen for a second win from their first two Bundesliga games.

Summer signing Corentin Tolisso hit the crossbar early on for the five-times-in-a-row German champions.
The opener came when Poland star Lewandowski backheeled Kingsley Coman's cross into the net.
And he scored his sixth goal in four games this season when he put a shot between the Werder keeper's legs.
Bayern goalkeeper Manuel Neuer kept a clean sheet on his return from a broken foot which forced him to miss the last month of last season.
Thomas Muller - who came on in the 73rd minute and had a hand in Lewandowski's second - was unhappy at not starting.
"Well, I don't really know what the qualities are that the coach [Carlo Ancelotti] wants to see. Obviously mine do not seem to be in 100% demand."
Elsewhere, former Bayern defender Holger Badstuber scored only the second Bundesliga goal of his career as Stuttgart beat Mainz 1-0.

A woman has been arrested in the US after allegedly locking her children, aged two and five, in the boot of her car while she went shopping.

US media report that Tori Castillo, 39, is facing child abuse charges and the children are now with their father.
Onlookers in the car park instructed the five-year-old on how to open the boot from the inside, reports say.
Passersby had noticed the car shaking and noise coming from inside where it was parked outside a Walmart.
The incident happened on Thursday in Riverdale, Utah. It is not clear how long the children were in the boot.
Local police officer Casey Warren told KTVX: "It's never right to lock a child inside of a vehicle, let alone a trunk of a vehicle.
"Obviously there's a lot of things that could go wrong."
He praised the "good Samaritans" who helped the children get out.
Under Utah state law, leaving a child under the age of nine unattended in a vehicle is punishable by a fine or jail time. The law was enacted in 2011 after repeated cases of children dying unattended in hot cars.


The new series of the BBC One hit show The Musketeers is returning with a "darker tone".

The cast have told Newsbeat that there will be a "more serialised aspect" where stories carry throughout the run.
Fans will also get to delve deeper into the back stories of each of the four main characters.
And now that the time the programme will be aired has been revealed, they can afford to show more graphic violence.
"There's a lot of death in the show. When it's an eight o'clock show, it's like bish, bash, bosh, you know, somebody's dead. And now of course you see the blade go in and you see it come out the other side," says Tom Burke, who plays Athos.
"I think a lot of the darkness is there."
Howard Charles, who plays Porthos, backs what Tom says and thinks the later time slot is "a good thing".
"It's necessary for the story," he says.
"We needed to move the story on, move the characters on and dig deeper and find those new depths and I think that the time slot is one factor that enables us to do that.
"But of course it hasn't changed from last season, it's still a nine o'clock show. It's just when we shot season one, we shot it with the view to making it an eight o'clock show.
"Whereas this season we knew it was going to be nine o'clock, so you know there are sort of CGI elements, and things like that and a bit more blood, guts. But also psychologically, it is darker and therefore fuller."
The cast also says that they were very happy with the success of the first series.
Luke Pasqualino who plays D'Artagnan says it's a good reward for their hard work.
"It's always very flattering when you put your heart and soul into something for so long, like seven months, and then you're always kind of nervous to see how the audience will react to it.
"We've all had that extra push to make it even bigger and better than the first. It's been good. We're happy."
The Musketeers starts on BBC One on 2 January at 21:00 GMT.

An investigation is under way after three prisoners gained access to the roof of Swansea Prison.

The men climbed on to the roof at 09:50 BST on Sunday, the Prison Service said.
A spokesman said the incident would be referred to the police, adding the prisoners had been moved to a segregation unit and would be stripped of privileges.
Ministry of Justice officials denied the protest had been linked to the smoking ban.
One claimed the prisoners involved were "recovering contraband items".


Joe Martin's second-half strike secured a point for Millwall as Bradford missed the chance to go top of League One.

Byron Webster's own goal from close range gave the visitors the lead just before the break.
The Lions equalised soon after half-time when Martin fired in with a fierce strike from the edge of the box.
Bradford went close to claiming all three points deep into injury time when Nicky Law's shot was turned onto the post by Jordan Archer.
The result leaves Bradford in second place, two points behind leaders Bolton, who were held at home by Southend, while Millwall are fourth.
The Lions made a bright start before Law's header was saved by Lions goalkeeper Archer.
City went ahead when Mark Marshall's cross-shot was turned away by Archer before hitting Webster's shin and bouncing into the net.
It did not take long after the restart for Millwall to equalise, as Martin fired past Doyle.
Archer then produced another fine save to deny Law at the death to ensure the Lions remain in touch with the top three.

Hartlepool have ruled out signing convicted rapist Ched Evans.

The 25-year-old was released in October after serving half of a five-year sentence for the rape of a 19-year-old woman in a hotel room in 2011.
Hartlepool manager Ronnie Moore had said he was considering signing the former Sheffield United striker.
But in a statement the club said they "do not intend signing Ched Evans" despite "his obvious ability as a football player".
Evans, who has played 13 times for Wales, maintains his innocence and has asked the Criminal Cases Review Commission to review his case.
Moore took charge of the Football League's bottom club on Tuesday.
Speaking after Saturday's 1-1 home draw with Oxford, he said of Evans: "He is a proven scorer. He's served his time and the boy wants to play football. If it could happen, I'd want it to."
Hartlepool have since announced Moore was responding "hypothetically" to an "unsubstantiated internet rumour".
In November, Sheffield United retracted an offer to allow Evans to train with them following strong local opposition.
TV presenter Charlie Webster, 60s pop star Dave Berry and Sheffield businesswoman Lindsay Graham all resigned as patrons of Sheffield United after Evans was invited to return to training. Musician Paul Heaton stood down as a patron of the club's community foundation.
Olympic champion Jessica Ennis-Hill stated that she wanted her name removed from one of the Bramall Lane stands should Evans play for the club again, while shirt sponsor DBL Logistics also threatened to end its backing of the club.
On Saturday Hartlepool's Labour MP Iain Wright said Evans was a "pariah" and signing him would send the wrong message to young fans.
Following Hartlepool's statement on Sunday, Wright told BBC Sport: "I'm really pleased that the owners of Hartlepool United have seen sense and Ched Evans won't be signing for Pools.
"It's a good message to send out that we won't have convicted rapists signing for Hartlepool United. We're a family club."


Plans to keep a record of UK citizens' online activities face a challenge from tech firms seeking to offer ways to hide people's browser histories.

Internet providers will soon be required to record which services their customers' devices connect to - including websites and messaging apps.
The Home Office says it will help combat terrorism, but critics have described it as a "snoopers' charter".
Critics of the law have said hackers could get access to the records.
"It only takes one bad actor to go in there and get the entire database," said James Blessing, chairman of the Internet Service Providers' Association (Ispa), which represents BT, Sky, Virgin Media, TalkTalk and others.
"You can try every conceivable thing in the entire world to [protect it] but somebody will still outsmart you.
"Mistakes will happen. It's a question of when. Hopefully it's in tens or maybe a hundred years. But it might be next week."
The Investigatory Powers Bill was approved by the House of Lords on 19 November and is due to become law before the end of 2016.
Now, several virtual private network (VPN) operators have seized on its introduction to promote their offerings.
VPNs digitally scramble a user's internet traffic and send it to one of their own servers before passing it on to a site or app in a form they can make sense of. A similar process happens in reverse, helping mask the person's online activity.
As a result, instead of ISPs having a log of everywhere a customer has visited, the only thing they can provide to the authorities is the fact that a subscriber used a VPN.
"We saw a boom in Australia last year correlated to when its data retention law went into effect," Jodi Myers, a spokeswoman for NordVPN told the BBC.
"And we are already seeing an increase in inquiries from the UK."
Ms Myers said her firm had just begun offering UK-based customers extra security measures - including encrypting their data twice and sending it via two servers - to address any concerns that its standard measures were not sufficient.
"Our biggest advantage is we have a zero log policy," she added.
"Our headquarters are in Panama, which doesn't have data retention laws, so it allows us to do this.
"And even in the worst-case scenario that our servers are confiscated, there would be nothing on them because of the way they are configured."
Another VPN provider said the UK government would find it difficult to prevent the use of such workarounds.
"The legislation specifically mentions connection service providers and not just ISPs, and the assumption is that VPNs based in the UK will have to give up their logs under this law," said Caleb Chen, a spokesman for Private Internet Access.
"But as a US-based company, my legal team has advised me that we would not be under any obligation to do so.
"And even if the government were to try to take it a step further and say no UK citizen could use a VPN that was not compliant with the law, those services would still be available."
He added that the widespread use of VPNs by businesses to provide staff with remote access to their email and other work-related files would also make it difficult to restrict the technology's use.
One of the UK's smaller internet providers, Andrews & Arnold, is looking into other ways to help its users circumvent the law.
"Customers can install a Tor browser, which encrypts traffic to one of thousands of different internet connections throughout the world hiding what they are doing," said  managing director Adrian Kennard.
"We are also working with a company called Brass Horn, which is planning to sell Tor-only internet access.
"In addition, we may base some of our own services outside the UK to reduce the amount of information that is logged and recorded. One possible place that we might put equipment is Iceland."
A spokeswoman for the Home Office declined to discuss ways it might tackle such efforts.
"The Investigatory Powers Bill provides law enforcement and the security and intelligence agencies with the powers they need to protect the UK and its citizens from terrorists and serious criminals, subject to strict safeguards and world-leading oversight," she said.
"Terrorists and serious criminals will always seek to avoid detection.
"To ensure they do not succeed, we do not comment publicly on the methods or capabilities available to the security and intelligence agencies."


A third series of Broadchurch has been confirmed after being revealed at the end of the show's series two finale on Monday night.

***SPOILER ALERT: If you're not up-to-date with Broadchurch series two, don't read on.***
The news was unveiled by an ITV continuity announcer as the closing credits started rolling.
The second series of Broadchurch ended with viewers finally finding out the killers in DI Hardy's Sandbrook case.
Ricky Gillespie confessed to killing Lisa Newberry while Lee Ashworth was revealed as Pippa Gillespie's murderer.
At the beginning of the final episode Danny Latimer's alleged killer, Joe Miller, was found not guilty.
Creator and writer Chris Chibnall said: "We've been overwhelmed that nine million people every week have continued to join us on the twists and turns of Broadchurch.
"This third chapter has been a glint in my eye for a long time and I'm thrilled to be writing these characters once again."
No details about the other cast members who will be joining Tennant's DI Alec Hardy and Colman's DS Ellie Miller have been revealed and filming dates will be confirmed at a later date.
So where does the show go from here? Here are the loose ends that need tidying up in series three.
So it was a case of community justice after Joe Miller was found not guilty of Danny Latimer's murder.
After being released from custody, Miller made his way to Reverend Coates' church.
But rather than allowing him sanctuary, Rev Coates rings up Danny Latimer's father Mark who brings his building partner Nige Carter round to the church.
They take him in their van to the chalet on the cliff where it's thought Danny Latimer was killed.
There he's told to leave Broadchurch forever by the whole family and his wife PC Ellie Miller.
The Rev Coates says he's got him a space at a halfway house in Sheffield. But will he go there?
At the end of the second series, DI Alec Hardy tells PC Ellie Miller he's not going to stay in the Dorset seaside town and wants to move closer to his daughter.
But at the end of the episode, Hardy is seen just about to get into a taxi presumably going to the local train station.
But does he get in or does he decide to stay?
If series two is anything to go by, it's not a done deal that Ricky Gillespie, Lee Ashworth and Claire Ashworth will be found guilty.
Despite confessing one after the other to being involved in Lisa Newberry and Pippa Gillespie's murders, in the world of Broadchurch that doesn't mean anything.
In a gripping finale, Lee Ashworth confesses to killing Pippa after her father admits killing 19-year-old babysitter Lisa.
He'd come home early from a wedding and walked in on her and Lee Ashworth having sex.
Claire Ashworth admits to helping cover up the whole thing.
Rev Coates consistently refuses to believe Joe Miller after he denies killing Danny Latimer in court.
He finally gives him up to Mark Latimer and his mate Nige after he's found not guilty of Danny's murder.
But will he go through a crisis of confidence after getting Joe Miller a place in a halfway house?
They're accused of having an affair in court by Joe Miller's defence barrister Sharon Bishop.
But PC Ellie Miller and DI Alec Hardy never actually get close to getting together.
At the end of series two, Miller refuses to hug Hardy despite being emotional after the conclusion of her husband's trial and helping to crack the Sandbrook murder case.
After losing the Joe Miller murder trial to Sharon Bishop, her former boss Jocelyn Knight offers to work with her again and help with her son's case.
But will she accept?
It doesn't look like it at the end of season two but that could change.

The joint leaders of Turkey's pro-Kurdish opposition party, People's Democracy (HDP), have been arrested along with at least nine other MPs.

Selahattin Demirtas and Figen Yuksekdag are accused of spreading propaganda for militants fighting the Turkish state.
Hours after Mr Demirtas was arrested in Diyarbakir, a car bomb killed eight people and injured more than 100.
Militants have been fighting for years to achieve independence for the Kurds, Turkey's biggest ethnic minority.
Turkey remains under a state of emergency that was imposed after a failed military coup in July.
The emergency allows President Recep Tayyip Erdogan and his cabinet to bypass parliament when drafting new laws and to restrict or suspend rights and freedoms.
The government says those detained had failed to respond to a summons for questioning and issued an arrest warrant for two other HDP MPs currently abroad.
This is a major escalation of a clampdown that has seen Kurdish media closed down and the mayor of Diyarbakir arrested.
Hopes of an end to Turkey's decades-long Kurdish problem have evaporated since a ceasefire with the [Kurdistan Workers' Party] PKK broke down in 2015, leading to a wave of tit-for-tat attacks.
Mr Demirtas elicited international support with his liberal politics but critics say he has failed to distance the party sufficiently from the PKK. Friday's detentions are likely to provoke more tension among Kurds - and more violence too.
The government says they were detained for failing to co-operate with a counter-terrorism investigation, which the two leaders vowed to boycott in June.
Defending the arrests, Justice Minister Bekir Bozdag said: "They did not respect the law."
The MPs are also accused of spreading propaganda for the PKK, the Kurdish group suspected of a wave of recent attacks including Friday's car bomb.
Deemed a terrorist organisation by the US, the EU and Turkey, the PKK has been fighting the state since the 1970s in a war which has claimed at least 40,000 lives.
Turkish politicians normally have immunity from prosecution but this was removed from the HDP and some other MPs in May.
Last month, the joint mayors of Diyarbakir, Turkey's largest Kurdish-majority city, were also arrested as part of a terrorism investigation.
While commonly seen as the main pro-Kurdish party, HDP is an eclectic grouping which also appeals to leftists, liberals, environmentalists, gay rights activists and pious Muslims. That explains why it is Turkey's third-largest party.
It entered parliament for the first time last year, winning 59 seats.
During the election campaign, it carried a moderate message despite dozens of attacks against party supporters and offices, culminating in a deadly attack on its largest election rally in Diyarbakir two days before the vote.
The party strongly denies any links to the PKK.
Mr Demirtas and others accuse President Erdogan of seeking to push the party out of parliament and increase his own power.
One MP, who is currently abroad, told the BBC the government was acting like Nazis.
"This crackdown tonight is nothing to do with procedural law, criminal law, any law whatsoever or the constitution," Ertugrul Kurkcu said. "This is an unlawful hijacking of HDP parliamentarians."
Turkey's HDP party goes mainstream
