Its are you reelin in the years . In the groups heyday in the 1970s, it scored hits with reelin in the years, do it again, and deacon blues. And in sport, britains Lewis Hamilton celebrates after winning this afternoons italian grand prix in monza. Good evening and welcome to bbc news. President trump has warned that the United States is considering cutting economic ties with any countries that do business with north korea. He issued the threat in a tweet after pyongyangs latest nuclear test, and says hes holding an urgent meeting with his National Security team. When asked if he would attack north korea, President Trump replied well see. The latest missile test is claimed to be a Hydrogen Bomb many times more powerful than those used in previous tests, and north korea said it was a perfect success, hours after seismologists had detected an earth tremor. The test took place at a site in the north east of the country. Analysts say the claims should be treated with caution, but that north Koreas Nuclear capability is clearly advancing. From seoul, in south korea, Yogita Limaye sent this report. State television, proudly announcing that the country has conducted another nuclear test. It was a perfect success, the newsreader said. Pyongyang claims to have detonated a Hydrogen Bomb at its Nuclear Testing site in the north east of the country. Hundreds of miles away in china, people say they witnessed tremors caused by the explosion. Experts believe it could be the most powerful weapon north korea has tested so far. Earlier in the day, these photographs were released of north Korean Leader kimjong un inspecting what is claimed to be a bomb. The country says the Nuclear Device its tested can be fitted onto an intercontinental missile. A serious threat, because it means pyongyang can arm these long range rockets it tested in july, missiles that put the us mainland infiring range. In south korea, an emergency meeting was held. Translation i cant help but be disappointed and outraged. North korea has made an absurd tactical mistake by creating a series of provocations such as launching icbm missiles and conducting a nuclear test, which has heightened tensions on the peninsula and is threatening world peace. It will isolate them further. Injapan, the Prime Minister called the latest test unacceptable. Translation if north korea forcibly conducted a nuclear test, its absolutely unacceptable and we have to strongly protest it. It comes less than a week after north korea launched this rocket. But its the us that north korea considers its biggest enemy, and the latest test is a step forward in its goal towards making weapons that could strike america. Regarding the United States, i think it could be a game changer, because the Hydrogen Bomb is sometimes 1,000 times more powerful than a nuclear bomb. That means kim jong un will threaten the United States that if you do not leave south korea, north korea would attack seattle, la or San Francisco with Hydrogen Bombs. Kim jong un has finally started respecting us, President Donald Trump has said just in the last fortnight, when it seemed as though the rhetoric from pyongyang had died down. Today, north koreas leader has shown that he has no intention to stop. Following President Trumps condemnation, the Prime Minister theresa may issued a statement deploring the missile test as reckless. She said it posed an unacceptable further threat to the international community, which must now come together to continue to increase the pressure on north koreas leaders to stop their destabilising actions. Well, so far, a series of us and un backed sanctions against the north have had little apparent effect on pyongyang. The us treasury secretary Steven Mnuchin told fox news that his department was preparing potent new measures that would completely cut off north korea economically. Idid speak i did speak with the president. Its clear that this behaviour is completely unacceptable. Weve already started with sanctions against north korea, but i am going to draft a sanctions package to send to the president for his strong consideration that anybody who wants to do trade or business with them would be prevented from doing trade or business with us. We are going to work with our allies. Well work with china, but people need to cut off north korea economically. This is unacceptable behaviour. In a moment, well be live in washington to speak to our correspondent richard lister. But first, lets hear from hamish de Bretton Gordon a former British Army Officer and chemical weapons expert. Hejoins me on webcam from bangalore in india. How disturbed are you by north koreas claims, firstly . The first thing to state is that everything that kim jong un has said thing to state is that everything that kimjong un has said he thing to state is that everything that kim jong un has said he will do in this nuclear crisis, he has done. And its pretty clear that he now has an Intercontinental Ballistic Missile with a range of over 4000 kilometres that he can probably put an atomic bomb, a much lesser bomb, but potentially with a yield of 20 kilotonnes, 20,000 tonnes of high explosive, to that missile and could fire it to the areas we have talked about guam and possibly mainland usa. When it comes to the h bomb test that allegedly happened today, from what i understand, although it was 6. 3 on the richter scale, i gather seismologists have decreed thatis gather seismologists have decreed that is probably a yield of 100 kilotonnes, much bigger than the atomic weapons he has already tested, but way short of a Hydrogen Bomb, a thermoNuclear Device. So in some, i think he does not possess a viable Hydrogen Bomb that he could put on his current missiles. But we have so underestimated his capability thus far that if we dont do something soon, he will have that ultimate capability. That has raised the suggestion which was made by the republican senator Lindsey Graham in an interview with Stephen Sackur from the Bbcs Hardtalk programme this weekend that unless something changes, it is inevitable that the United States would have to consider a first strike. Presumably, that option is one that nobody wants, but the range of options seems to be narrowing all the time, given that dialogue doesnt appear to have worked. Sanctions dont appear to be effective, given that this country is relatively primitive economically doesnt have many trading partners, and china doesnt appear to be prepared to cut ties with north korea, not least because it is worried about the korean regime collapsing and the chaos that would follow. Do you see any other options . I think youre right. Kim jong un has absolutely got to believe that there will be a us and coalition of the willing first strike, predominantly the permanent five, and i would like to see russia and china be far more demonstrative in this. Of course, we want a diplomatic solution. But as you said, nothing else is having a great effect. Sanctions are not necessarily going to have an impact, and unless he believes his Nuclear Capability is going to be taken out, we are going to continue down this line. And as i said previously, all the time we give him will allow him to develop terrifying h bomb which he desires, and in h bomb would flatten a city like london or mumbai 01 flatten a city like london or mumbai or new york, whereas his current atomic capability would just flatten atomic capability would just flatten a few blocks. Thanks very much for being with us. As i mentioned, senator Lindsey Graham thinks the us might have to make a first strike u nless might have to make a first strike unless something changes. This is what President Trump had to say on the matter when he left church a couple of hours ago. Mr resident, with the attack north korea . Will see. So he leaves the option open. Let me bring you some breaking news from the United Nations, where the secretary Antonio Guterres has condemned north Koreas Nuclear test is profoundly destabilising for regional security. We expect a further meeting of the Un Security Council as sooner such a meeting can be scheduled. Lets cioss meeting can be scheduled. Lets cross to washington and our correspondent richard lister. Things are developing fast in terms of the us reaction. Can you sum up what we have heard from washington in the last few hours . Yes, we heard that clip of the president clearly keeping his options open. That is to be expected. He has been very bellicose in recent weeks and months about the prospect for north korea, should it pursue its Nuclear Weapons programme, that the United States could react with fire and fury, that American Forces are locked and loaded. But realistically, the sense in washington at the moment is that there has to be more done short of military option before it comes to that point. So most of the rhetoric from washington today seems to be about enhancing sanctions, with some tough talk both from the treasury secretary and from President Trump, both of whom say they are considering sanctions against any country that trades with north korea. That talk is clearly aimed at china, which is responsible for about 90 of north koreas international trade, washington making clear that it is thinking seriously about whether to put a trade embargo in place that would affect china and other nations that trade with north korea. The whole Us China Relationship is fascinating under this administration. This morning, to trump was talking about north korea embarrassing china and china not prove incapable of doing much about it. This is another kind of poking china with a stick, but also saying, we want that a corporation. Is there much hope in washington that the chinese will respond positively to that kind of pressure . Well, there is recognition in washington that chinas view is that frankly, it would rather have a Nuclear Armed ally on that border than a failing state evolved into economic chaos, with the potential for millions of refugees pouring over the border into china, which is why china has resisted enforcing the kind of tough sanctions United States would like. It simply isnt in chinas best interests. Washington seems to be saying now, look, it is in your best interests, because if you decide not to enforce the toughest sanctions that might make some progress, you will find yourself having a difficult time trading with the us, which is one of chinas biggest trading partners. Trade between the two countries is worth 650 billion last year. That seems to be the choice that washington is putting before beijing. Let me ask you about lindsey gra hams intervention. Beijing. Let me ask you about Lindsey Grahams intervention. He is attending a summit in italy and Stephen Sackurfrom attending a summit in italy and Stephen Sackur from hardtalk was there yesterday, speaking to him. The interview goes out tomorrow on bbc news. Mr graham had this rather controversial quote about saying it is tough, but if there were to be a first strike by the us, the people who would die would be in north korea, and therefore we dont feel the same as if we were contemplating something that might mean people dying in the United States. It is not a pleasant idea under any circumstances, but what he has said in response to having it back at him is, dont this understanding, but if something doesnt change, it is inevitable that america will have to engage in a First Military strike because north korea seems hell bent on developing technology. Is there a kind of drumbeat towards this in washington that you are detecting . dont think there is a significant drumbeat, no more than there has been. There are plenty of people who, and this is particularly true of republicans in congress, who say, we cannot allow north korea to get to the stage where it has a fully functional Intercontinental Ballistic Missile system with Nuclear Armed warheads which it is able to fire with impunity at cities across the us. They say at the moment, they are moving towards that, but is it better to risk a first strike against north korea now before we are fully confident that they have that capability, or is it better to wait until we know they definitely have that capability, perhaps in a years time, at which point we are at greater risk . That is the calculation by many people like senator graham. At the moment, the calculation from the white house is that it is better to pursue other measures short of military action. But that calculation will certainly have to be refined the closer that north korea gets to developing a system which has the ability to fire on the United States with impunity. Thanks.

The brexit secretary, david davis, says the European Commission is making itself look silly by claiming that little progress is being made in talks with britain. Hospital chiefs warn that the nhs in england may suffer its worst winter in recent history if it does not receive an emergency bailout. The brexit secretary, david davis, says the European Commission is making itself look silly by saying that talks with britain arent making progress. The eus chief negotiator, Michel Barnier, says he doesnt want to punish or blackmail the uk, but the british people need to understand the extremely serious consequences of leaving. All this as theresa may, later this week, faces a parliamentary battle with the first commons vote on brexit legislation. Emma vardy reports. After three rounds of talks, the two sides still appear some way apart. Theres disagreement over the size of the so called and eus chief negotiator, Michel Barnier, said this week that no decisive progress had been made on key issues. Today, a defiant david davis said the uk would not be pressured into paying more than its fair share. We are basically going through this very systematically, very british way, very pragmatic way of doing it, and of course hes finding it difficult and he wants to put pressure on us which is why the stance this week in the press conference. Bluntly, i think it looked a bit silly because there plainly were that things we had achieved. Meanwhile, Michel Barnier has said he does not want to punish or blackmail the uk, but that he will use the opportunity to teach british people and others what leaving the eu means. His remarks were made in an off camera briefing in which he said there were extremely serious consequences to leaving the single market, and that it could never be better than being a member of the club. On thursday, mps will debate the withdrawal bill, which will convert thousands of eu regulations into british laws, but labour has said it will vote against the bill unless substantial changes are made, warning it could erode rights and freedoms that workers currently enjoy. I flagged these points up at the beginning of the summer and said if you dont address them, we will vote against it. I havent reached that stage yet but ive been very clear whilst we accept the result of the referendum, we are not giving a blank cheque to the government to do it in whatever way it wants, because its not in the public interest. Theresa may has appealed for unity. Any potential rebellion from just a handful of tory mps could derail it. There is a crucial week for brexit ahead, marked by division in westminster, and in brussels. Emma vardy, bbc news. Hospital managers in england have called for an emergency financial bail out, saying they are bracing themselves for the worst winter in recent years. Nhs providers which represents the vast majority of health trusts says at least £200 million of extra funding is needed to pay for more staff and beds. But the department of health says the nhs is better prepared for winter this year than ever before, as Angus Crawford reports. Winter puts hospitals under pressure. Each year, there is an increase in demand, more patients needing a wider range of treatments in an already stretched service. After Serious Problems last winter, theres been intensive planning to deal with this
