:00:19. > :00:22.President Obama has warned that the possibility
:00:23. > :00:24.of so-called Islamic State obtaining a nuclear weapon
:00:25. > :00:27.is one of the greatest threats to global security.
:00:28. > :00:30.Speaking at the end of a nuclear security summit in Washington,
:00:31. > :00:32.he insisted that concrete steps must be taken
:00:33. > :00:37.to prevent nuclear terrorism, as Sophie Long reports.
:00:38. > :00:39.Good afternoon, everybody. If we could get started...
:00:40. > :00:44.President Obama said they gathered here not just to talk but to act.
:00:45. > :00:47.More than 50 world leaders came together.
:00:48. > :00:50.They pledged to do more to stop nuclear terrorism -
:00:51. > :00:53.attacks that he said would change our world.
:00:54. > :00:57.At the forefront of his mind, the so-called Islamic State,
:00:58. > :01:01.the organisation already accused of using chemical weapons in Syria.
:01:02. > :01:08.There is no doubt that if these madmen ever
:01:09. > :01:10.got their hands on a nuclear bomb, or nuclear material,
:01:11. > :01:13.they most certainly would use it to kill as many innocent
:01:14. > :01:18.And that is why our work here remains so critical.
:01:19. > :01:21.The single most effective defence against nuclear terrorism
:01:22. > :01:24.is fully securing this material so it doesn't fall into the wrong hands
:01:25. > :01:28.The world leaders also expressed concern at the prospect
:01:29. > :01:32.of North Korea developing a workable nuclear weapon.
:01:33. > :01:35.Pyongyang test-fired a missile during the Washington summit,
:01:36. > :01:39.underlining its determination to go its own way,
:01:40. > :01:43.and blamed the US for the tensions on the Korean Peninsula.
:01:44. > :01:48.The United States is trying to turn the white into black,
:01:49. > :01:56.describing as if the counter measures taken by the government
:01:57. > :01:58.of the DPR Korea is a provocation, is a threat.
:01:59. > :02:00.They said it is a threat and a provocation,
:02:01. > :02:06.Much will depend on the attitude of China's President Xi.
:02:07. > :02:09.He was urged by Barack Obama during the summit
:02:10. > :02:11.to impose new sanctions and put pressure on Pyongyang
:02:12. > :02:14.to end their nuclear weapons programme.
:02:15. > :02:17.This is the last of these summits in their current form
:02:18. > :02:20.as President Obama prepares to leave office.
:02:21. > :02:22.He said they had made meaningful progress
:02:23. > :02:28.As the summit closed, they reaffirmed their commitment
:02:29. > :02:31.to fight nuclear proliferation, saying it still posed the greatest
:02:32. > :02:42.The UK steel industry is coming to terms with another setback,
:02:43. > :02:45.following the news that China is to impose a 46% import tariff
:02:46. > :02:46.on certain types of high-grade steel.
:02:47. > :02:50.Britain is among one of only a handful of countries
:02:51. > :02:54.which produces the steel, mainly used for electrical transformers.
:02:55. > :02:56.Let's speak to our political correspondent Carole Walker,
:02:57. > :03:11.This is terrible news. Making in Britain, but also for the
:03:12. > :03:13.Government. That is right, and a spokesman at the business department
:03:14. > :03:17.has said it is clearly unwelcome news but that exports of the
:03:18. > :03:22.particular type of steel that would be hit from South Wales are only
:03:23. > :03:28.about 1000 tonnes a year, so the impact on British industry is likely
:03:29. > :03:31.to be minimal. Nonetheless, this is embarrassing for the Government,
:03:32. > :03:34.particularly as the Chinese simply slapped on these new tariffs within
:03:35. > :03:42.hours of David Cameron raising concerns about the issue when he met
:03:43. > :03:44.President Xi at that nuclear summit in Washington. And as the Government
:03:45. > :03:47.is facing accusations that it is not taking sufficiently robust action on
:03:48. > :03:52.the steel issue because it is more concerned with wooing Chinese
:03:53. > :03:55.investment in other industries. It does, of course, underlined the
:03:56. > :03:58.speed and the scale with which other countries are acting to save their
:03:59. > :04:03.own steel businesses at a time that Britain is not only trapped in this
:04:04. > :04:07.rather slow and cumbersome EU process, but has argued against some
:04:08. > :04:11.higher tariffs because it says they would hit other parts of British
:04:12. > :04:19.industry. Certainly, there are many in the steel business here to say
:04:20. > :04:21.the Government cordoned should do more if it is to save the British
:04:22. > :04:24.steel industry and keep alive the prospects of finding a buyer for the
:04:25. > :04:29.huge steel plant at Port Talbot. Carole, thank you.
:04:30. > :04:32.The Syrian Army says it's discovered a mass grave with around 40 bodies
:04:33. > :04:34.in the city of Palmyra, according to state run media.
:04:35. > :04:36.Palmyra was recently recaptured by government forces
:04:37. > :04:37.from the so-called Islamic State jihadist group.
:04:38. > :04:39.International monitoring groups say IS was reported
:04:40. > :04:42.to have killed a number of civilians and soldiers some time ago.
:04:43. > :04:44.Three employees of an Indian construction firm
:04:45. > :04:46.are due to appear in court today, charged in connection
:04:47. > :04:49.with the collapse of a flyover in Kolkata on Thursday.
:04:50. > :04:54.as a section of the flyover fell onto the road below.
:04:55. > :05:00.Five other staff from the company are being questioned.
:05:01. > :05:03.There are concerns that neither Greece or Turkey are properly
:05:04. > :05:06.prepared to begin the return of migrants from the Greek Islands
:05:07. > :05:11.The deportations follow a EU agreement to try and stem the flow
:05:12. > :05:15.of migrants into Europe from Syria and elsewhere.
:05:16. > :05:21.Our correspondent Mark Lowen is in Dikili, northern Turkey.
:05:22. > :05:29.He joins us by webcam. Mark, how prepared is Turkey for what is a
:05:30. > :05:34.very complicated process? It is a huge task, Gavin, it does not seem
:05:35. > :05:38.that it is prepared at all. We are in Dikili, just across the Aegean
:05:39. > :05:41.Sea from Lesbos, where the first batch of 500 migrants are supposed
:05:42. > :05:44.to arrive on Monday, but we have been to the field which has been
:05:45. > :05:54.earmarked as the registration centre, and there is nothing there
:05:55. > :05:58.at all. Added to that, there is a lot of anger from locals at the idea
:05:59. > :06:01.of any camp at all, and there was a protest in the main square about an
:06:02. > :06:03.hour ago by people saying they do not want a refugee camp. Local
:06:04. > :06:06.people are saying they could stay here temporarily before being
:06:07. > :06:10.relocated to other parts of Turkey. And there are real concerns among
:06:11. > :06:13.aid agencies and EU countries that those being sent back could have
:06:14. > :06:18.their rights violated if they are sent back to their countries of
:06:19. > :06:21.origin. It is a mad panic rush to meet the Monday deadline and major
:06:22. > :06:23.concerns over whether it can work. Thank you very much.
:06:24. > :06:26.A British woman taking part in a round-the-world yacht race
:06:27. > :06:27.has died after being swept overboard.
:06:28. > :06:30.Tributes have been paid to Sarah Young, who was from London.
:06:31. > :06:32.The founder of the Clipper race said safety was the first priority.
:06:33. > :06:35.He warned other crews that she was not tethered to the boat,
:06:36. > :06:38.as the usual safety procedures require.
:06:39. > :06:41.The fact of the matter is, people have a harness
:06:42. > :06:42.and don't clip on, they are endangering themselves,
:06:43. > :06:45.and I'm afraid that's what's happened on this occasion.
:06:46. > :06:48.You can tell them to harness on, we do the whole time,
:06:49. > :06:53.but if they haven't done it, I'm afraid this is what can happen.
:06:54. > :06:56.You can see more on all of today's stories on the BBC News Channel.
:06:57. > :06:59.The next news on BBC One is at 5:50 this evening.
:07:00. > :07:23.Hello! Lovely warm Springs signs for some of us today, but for others it
:07:24. > :07:24.is rather less inspiring, particularly if you are sitting
