earlier us president donald trump urged europe — and the uk — to take back and put on trial, hundreds of so—called islamic state members captured in syria and iraq. mr trump warned that if nothing was done, america would be forced to release the is detainees. it's thought almost 6,000 nationals from western europe travelled to syria and iraq tojoin the militant group. on friday, mr trump predicted the final defeat of is, on the ground. as jane frances kelly reports that battle is not quite over. us—backed kurdish forces are continuing their assault on the final part of its territory in eastern syria. in a series of tweets, donald trump urged britain, france, germany and other european allies to take back over 800 isis fighters that were captured in syria and put them on trial. he said the caliphate was ready to fall and if they didn't act, america would be forced to release the fighters, warning they would permeate europe.

culture secretary and former attorney generaljeremy wright agreed that britain would have to deal with its own citizens. if you are dealing with a british citizen who wants to return to this country and they are not a dual citizen, so their only citizenship is british citizenship then we are obliged, at some stage of these, to take them back. at some stage at least, to take them back. that doesn't mean that we can't put in place the necessary security measures to monitor their activities and make sure they are not misbehaving. the shadow chancellor agreed with trump that britain should take responsibility for its citizens. we have to make sure we respond to our international duties of bringing war criminals to book and we will make that contribution. now, whether that's collectively and it's the hagel whether it's and it's the hague or whether it's bringing them back here, whatever, we got to step up to that responsibility. i'd rather they were under lock and key than they were somewhere else, potentially a threat to this country. a former head of the british army said it was a mistake to think

is had been defeated. it's not 100% victory. we may well complete the recapture of the territory that they had, but the ideology, the thinking, the support behind it, that is going to continue and that will remain the struggle for this generation, perhaps even the next generation as well. accepting fighters and their families back creates security issues and is often unpopular, but many argue to ignore them is to create an even bigger threat in the future. the young british woman who ran away tojoin is in syria, shamima begum, says she's given birth in a refugee camp. the 19—year—old says she wants to return to the uk with her baby boy. she's been at the centre of a debate in britain about her possible return, with many arguing she should not be allowed back. ms begum left four years ago aged 15 to join the militant group. a fire has swept through more than 200 slum dwellings

in southern bangladesh. police and firefighters say at least nine people were killed and more than 50 others injured in the city of chittagong. sodaba haidare reports. the fire broke out in the early hours of sunday morning, when the slum dwellers were asleep. more than 200 shanty homes were destroyed. the houses of bamboo, tin and tarpaulin never stood a chance. these people are already amongst the country's tourist. now they have nothing. a mother shouts "everything is gone!" they can only comfort each other. amongst the dead, four members of the same family. more than 50 others were injured. the death toll is expected to rise.

0fficials death toll is expected to rise. officials are investigating the cause of the firebird say it may have been generated by a short circuit. fires regularly break out in bangladesh's slums, where many grid millions live in squalid conditions. safety regulations are rarely followed and accidents like these kill hundreds every year. let's take a look at some of the other stories making the news. the saudi crown prince, mohammed bin salman, on a visit to pakistan, has announced investment agreements worth $20 billion, including an $8 billion oil refinery. he described it as just the start of an economic tie—up. pakistan's prime minister, imran khan called saudi arabia a friend in need. protestors are back on the streets of paris again, after police used tear—gas to try to control them on saturday night. the gilets—jaunes — or yellow vests — as they're called, started as a protest against high fuel prices. the prime minister of poland, mateusz morawiecki, has cancelled a visit to israel

in a growing row over anti—semitism. mr morawiecki was angered by comments from the israeli prime minister, benjamin netanyahu, that poles had been responsible for the killing of jews during the second world war. the former acting director of the fbi says the deputy us attorney general, rod rosenstein, considered measures to remove president trump from office in 2017. andrew mccabe told cbs television that mr rosenstein discussed with him how many cabinet members would support such a step after mr trump abruptly dismissed the fbi director, james comey. here's a bit of that interview. the discussion of the 25th amendment was simply... rod raised the issue and discussed it with me in the context of thinking about how many other cabinet officials might support such an effort. rosenstein was actually openly talking about whether there was a majority in the cabinet

who would vote to remove the president? that is correct. for more on this, i'm joined by our washington correspondent, chris buckler. chris, what is the mechanism, then? is this something that was technically possible for them to do? so the 25th amendment is away, essentially, replacing a president and there has to be that mechanism in case a president dies, in case he resigns or in kc isn't able to do hisjob and resigns or in kc isn't able to do his job and it resigns or in kc isn't able to do hisjob and it has been resigns or in kc isn't able to do his job and it has been used resigns or in kc isn't able to do hisjob and it has been used in the past, for example when people have gone for a medical operation. temporarily, power is passed to the vice president and that is what the 25th amendment is there to do but it is also there should the president no longer be able to fulfil his duties and that needs the cabinet to really weigh in and give their support to it. essentially, it needs

the support of the vice president and the majority of the cabinet and what andrew mccabe, former deputy director of the fbi and at one stage acting director of the fbi is claiming is that at one stage, rod rosenthal, the us deputy attorney general, had a conversation saying, listen, the 25th amendment, could we potentially use this and with the cabinet supported? potentially use this and with the cabinet supported ? that potentially use this and with the cabinet supported? that is obviously something very serious to allege about the us attorney depth —— deputy attorney general and in the past, he has made it clear that if he ever made those comments, he was onlyjoking and he ever made those comments, he was only joking and is he ever made those comments, he was onlyjoking and is denying he ever meant anything like what is being suggested by andrew mccabe. has there been any response to this by there been any response to this by the white house yet? we have had a response more from republicans. these kind of conversations have been happen sometime, suggestions that rod rosenstein had made these kind of allegations and also suggesting that even at one stage he may have suggested secretly

recording donald trump. what republicans have said as they want to try and put this in some sort of contexts, they want to potentially subpoena rod rosenstein and andrew mccabe to try to get to the bottom of what conversations were being had in the department ofjustice in the time afterjames comey was fired as fbi director and replaced by andrew mccabe. and what was it in particular about the dismissal of james comey that would have triggered these conversations? because there were various senior level people who were dismissed by the president. yes, you have to put all of this into context. this is also relating to robert mueller‘s investigation which, of course, started as an fbi investigation. the special counsel is looking into allegations that russia interfered in the 2016 election and claims of potential collusion involving the trump campaign. what is being suggested here is their conversations were being had at that time about whether or not james

comey was removed as a result of concerns about president trump and what was then an fbi investigation, and now the department ofjustice afterwards were looking at what president trump was doing, what president trump was doing, what president trump was saying and whether or not it was impacting on theirjob. 0f whether or not it was impacting on theirjob. of course, these conversations we will learn something about in andrew mccabe's interview tonight on 60 minutes and also in his book, which is being released, called the threat. chris, thank you. the british prime minister has called on conservative mps to put aside "personal preferences" and support a brexit deal in the house of commons. theresa may's plans were rejected in a vote last week but today one of her senior ministers indicated that there might be a solution to the disagreements within the party, that doesn't involve reopening the withdrawal agreement. ben wright reports. the lobbying of eu leaders will continue apace this week as theresa may tries to deliver on her pledge to secure legally binding changes

to the irish backstop, the most contentious part of the brexit deal, there to ensure no hard border on the island of ireland. but today, one cabinet minister said changes could be made without reopening the whole agreement. if there are other ways of doing it that are just as effective, that perhaps we haven't explored... so you think a legal letter or codicil or something... ? well, as i say, i don't think it's the mechanism that matters, it's the objective. many brexit enthusiasts on the tory backbenches will not like that. they want the withdrawal deal rewritten or the backstop ditched altogether. well, the european union has said that it won't reopen negotiations at all, but that is what you would expect them to be saying until the government goes with a very firm plan. i think the ball is in the government's court. the ayes to the right, 258. the noes to the left, 303. last week, divisions in the tory party were on full display when the prime minister lost another big vote on her brexit strategy. last night, she wrote to all tory

mps appealing for unity, asking them to put personal preferences aside for the national interest. labour has divisions, too, and today, there was this appeal from the leadership to mps thinking of quitting the party. we are holding the party together on brexit. those who are saying, "well, we'll split if we don't get a people's vote," well, we've still kept that option on the table. it might come about. why split over that? meanwhile, businesses watch the political limbo with alarm. what we're concerned about is the prospects of a no—deal. there's no such thing as a managed no—deal. it is absolutely catastrophic for us. the prime minister's missive to her warring party warns that a no—deal brexit will disrupt the economy and damage jobs. and it is the default position if parliament doesn't approve a deal by the end of march. but will theresa may really let that happen? it's one of the biggest unknowns in this crisis.

what is clear is that soon, some mps, maybe even some ministers will try again to shut down the option of a no—deal brexit and force an extension to the brexit talks if the prime minister can't get a deal through. and today, president macron echoed what other eu leaders have said all along — the withdrawal deal is not renegotiable. this week, again, the prime minister's room to manoeuvre looks very tight. stay with us on bbc world news, still to come... spectators in venice look to the moon, as the world—famous carnival gets underway this year with a lunar theme. nine years and 15,000 deaths after going into afghanistan, the final

soviet troops were coming home. withdrawal completed in good order but the army defeated in the casket was sent to perform. it had a terrible effect on the morality of the people and repercussions in the street. 0ne the people and repercussions in the street. one wonders who is next. as the airlift got under way, there was no letup in the eruption itself. lava streams from a bent low in the greater blow down to the sea on the east of the island, away from the town for the time being but it could start flowing again at any time. the russians heralded a new generation space station with a spectacular night launch. they call it mir, the russian for "peace". this is bbc world news today. the latest headlines... president trump has demanded that

europe takes back more than 800 islamic state fighters captured in syria to put them on trial. a fire in the south of bangladesh has swept through more than 200 slum dwellings. police say at least nine people were killed and more than 50 others injured. the aberdeen—based airline loganair has said it will take over some of the services provided by flybmi. hundreds of passengers were left stranded after the company filed for administration and cancelled all flights last night. thousands of customers have been affected, as stuart flinders reports. it's a sign of how vulnerable small airlines are. 17 aircraft, 25 european destinations, not enough passengers. john carney did use flybmi for business travel. after spending £1,500 with them last week, he received a text message yesterday saying his flights had been cancelled. the phoneline is now dead.

it's annoying. 0bviously, they must have known on wednesday that they were not going to be in business for very much longer and they were still happy to take bookings on wednesday. it's just a shame that they didn't give us more warning. flybmi says it can't organise alternative flights or give refunds. flybmi has blamed rising fuel and carbon costs for its problems, but also uncertainty about brexit, which it says has prevented it from negotiating contracts to fly between airports within the eu. but you only have to look at the airline's own figures from last year. 18 was the average number of passengers on every plane. and that's a lot of empty seats. this isn't really because of brexit. flybmi is not disappearing simply because of that. it's going because the brand wasn't strong enough and not enough people wanted to choose to fly bmi. also the balance sheet was weak. they simply didn't have

the cash to keep going. so when you combine all of those you have a very turbulent melting pot for an airline. flybmi operated from small regional airports including bristol, newcastle and aberdeen. the route between the city of derry airport and stansted received a public subsidy to promote trade and travel between northern ireland and the rest of the uk. nearly 400 jobs here and elsewhere in europe are now also in doubt. us airforce transport planes carrying humanitarian aid for venezuela have landed at the colombian border. president maduro has refused to allow the aid in, accusing the us of trying to organise a coup. us officials say the aid has been requested by the venezuelan opposition leader, juan guaido. jon ironmonger has the latest. it is an operation both humanitarian and highly political. arriving on the colombian border, three us cargo planes carrying food, medicine and clothes for the people of venezuela.

this is not the first shipment, nor will it be the last, not only from the united states but we know many other countries arejoining as well. aid packages are being stockpiled at the request of the venezuelan opposition leader, juan guaido, in colombia, brazil and the caribbean. speaking at a rally in caracas, the self—proclaimed interim president appealed to new volunteers to help carry supplies over crossings next saturday. he restated an ultimatum for the armed forces to back down. translation: once again, the message to the venezuelan armed forces, seven days for humanitarian aid to enter, a week for you to do the right thing and put yourselves on the side of the constitution. we are authorising the entrance of not only humanitarian aid but also humanity.

us officials say venezuela is in the grip of an economic crisis, leading to widespread hunger and a critical shortage of basic medicines. according to the united nations, 3 million venezuelan migrants have fled the country since 2015. us aid drops are intensifying the stand—off with nicolas maduro, who has called the operation a disguise for an invasion. maduro's still loyal military have barricaded bridge crossings and show no signs of giving way. time to get all of the latest from the world of sport and we can join john watson. many thanks indeed. we begin with football, no major upset in the fifth round of the english fa cup to tell you about with premier

league side crystal palace and wolves reaching the quarterfinals and avoiding the embarrassment of that comes with losing to lower league opposition. alice won 2—0 thanks to jeffrey schlupp's league opposition. alice won 2—0 thanks tojeffrey schlupp's early goal against third tier doncaster, a strike with the aid of a deflection to put them on their way. they doubled the advantage through max meier on the stroke of half—time, a nice head after the ball came back across the goal. doncaster couldn't find a response and so palace march on. beaten finalists twice before in the fa cup. i thought that they did a fantasticjob really, and they must be very proud, i would think of their performance because it was certainly an even sort of game for long periods but luckily we scored two good goals and that saw us through, so we got to be very happy with that and these matches are real ba na na with that and these matches are real banana skins, really, because people don't give doncaster rovers and this type of team the type of credit that

they should do. high-flying wolves b championship side bristol city 1—0 in the early tie of the day. ivan cavaleiro with the decisive goal just before the half an hour mark. bristol city have won nine games in a row in the lead up to this one, so the upset was on and improved dramatically after the break. dasilva wasting their best chance and wolves hung on. and it could be said the game of the day was in south wales between championship sides of swansea and brentford. swa nsea sides of swansea and brentford. swansea coming out on top, despite benford taking an early lead through watkins. but two goals in four minutes after the interval swung the match in swa nsea's minutes after the interval swung the match in swansea's favour. minutes after the interval swung the match in swansea's fav| a r. minutes after the interval swung the match in swansea's fav| a great james with the second, a great breakaway run. brentford were reduced to ten men before celina made it 3—1 and they sealed the win late on, byers picking his spot for

swansea's fourth, as they reach the last date for the second year in a row. so this is the quarterfinals are shaping up, these are the teams in the last eight. five premier league sides currently, it will be six but who willjoin them, chelsea manchester united ? arguably six but who willjoin them, chelsea manchester united? arguably the standout tie still to be played, that matches on monday night. real madrid captain sergio ramos received the 25th red card of his career as real madrid suffered a shock home defeat to girona. it was a bad day at the office all round for sergio ramos, he gave away the penalty from which girona scored and equalised and then after they had scored the winner, he was subsequently sent off in injury time for a second yellow card. this is how those dismissals have stacked up. 20 of them have beenin have stacked up. 20 of them have been in the spanish league. in all of the major european leagues, no one has been sent off more. he overta kes

one has been sent off more. he overtakes the previous record holder cyril rool. duncan ferguson, richard dunne and patrick vieira with the worst disciplinary record in the premier league, but nowhere near sergio ramos. the big hitting batsmen chris gale will retire from one—day internationals after the summer world cup. the announcement was made by cricket west indies a short time ago. the 29—year—old —— 39—year—old will focus on 2020 cricket, format he excels in, holding the record for the highs to individual score, 175 ofjust 66 balls. america's nellie korda added another chapter to her family's incredible sporting success story with victory in the women's australian open. she carded a final round of 67 to finish 17 under par, two shots clear, to claim her second lpga title. she is the latest in her

family to win an aussie open of some kind. her sisterjessica won the same tournament seven years ago. and thatis same tournament seven years ago. and that is all the sport. thanks, john. thousands of people have lined the famous canals of venice for the launch of the traditional carnival — which will run for two weeks. the water—based parade produced a certain wow—factor — which is unique to the city. freya cole has more. gracefully floating above the famed canals of venice, a woman performs in the annual floating parade. above her, the mysterious man on the moon, a symbol of this year's carnival theme, "blame the moon", marking 50 years since the first landing. the venice carnival tradition dates back centuries and is famous for the stylised masks donned by revellers. translation: this event is wonderful because it is a way to express yourself to bring joy,
