welcome to bbc news. the family of shamima begum — one of three british school girls who left britain to join so—called islamic state — say they've been told that she's given birth. shamima, who's now 19, was found last week in a syrian refugee camp by the times newspaper. she said she wanted to bring up her baby in britain, as she had lost two other children while living with is. it comes as president trump warns the uk and other european countries to take back hundreds of members of is, captured in syria and iraq, and to put them on trial. jane frances kelly has more. the teenager, shemima begum, who travelled to syria to join the islamic state group as a schoolgirl of 15 four years ago is thought to have given birth to a son. a statement from the family's lawyer said mother and child were believed to be in good health, but they were still trying to make direct contact with her.

the birth comes as debate rages about the best way to deal with those returning from the is caliphate. 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 did not 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, so they're only citizenship is british citizenship, we are obliged to take them back. that does not mean that we cannot put in place the necessary security measures to monitor their activities and make sure that 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. we'll make that contribution. whether that's collectively, the hague, or bringing them back here, we've got to step up to that responsibility. i would rather they were under lock and key than 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, this is going 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 that to ignore them is to create an even bigger threat in the future.

jane frances kelly, bbc news. our home affairs correpondent daniel sandford explained to me what's known about shemima now and how the authorities may handle her case in the future. the information came to the lawyer who is currently representing shemima begum's family, and he said they had information that she had given birth, and he went on later to say that it was a baby boy. they said they had not had direct communication with her, so they were trying to verify the information themselves. butjournalists in the camp have seen what appears to be a baby in the room with shemima begum, so it does looks as if it's possible at least that she has given birth overnight. the only information that she was pregnant in the first place came from her, in her interview with the times. there's no certainty in this, but it does look as if she has had a baby. she's a british citizen.

presumably there is a question mark about the rights of the baby to come to this country, brought back to britain. clearly, mum wants to come back. what are the options for the authorities, in terms of admitting her and what they do with her if she comes back? first off, the home secretary, sajid javid, has said he will not hesitate to try and stop people coming into the country who have gone to join terrorist organisations. that's easy to say. it's actually not quite as easy to implement, because if someone does not have any other option in terms of citizenship, you cannot take away their british citizenship, not a 19—year—old... that means you then have to kind of accept that they might be british and therefore you might have to allow them back into the country. that does not mean they are allowed to come back and resume their lives, though, because that return can be managed using what is called a temporary inclusion order. they can be told they're not allowed to come back until things have been put in place. and what might be put in place is for the police to meet

someone on a plane, interview them, held in custody if they have been charged. they could be put under a degree of control, either using the measures or police bail measures. so someone would come back and be heavily investigated, and — to a degree — controlled for a while. there are other options around the security service monitoring people's behaviour. depending on who it might be, shemima begum may not fit into this category... there's also what is known as the returning families project, which is an attempt to try and reintegrate these sorts of people back into society. though, so far, a very, very small number of people have really gone through that. it is not clear yet how successful that may or may not be. home affairs correspondent daniel sandford. passengers with flybmi have been speaking of their frustration at the airline's abrupt collapse. the company announced last night that it was calling in administrators and cancelling all flights with immediate effect. in a statement, flybmi said it had

run into financial difficulties, partly because of brexit. stuart flinders has more. it's half term and some travellers have begun their holiday not sure how it will end. i'm in a lay—by off the autobahn in munich. we've been caught up in the bmi saga today. we arrived at bristol airport to catch a flight, only for it to be cancelled at very short notice. we are now off into austria for ourskiing trip, but there is a real concern as to how we're going to get home. flybmi say they can't organise travel with other airlines themselves, nor will passengers be refunded. there are unfortunately going to be a lot of people out of pocket. for those of you, for those people who aren't able to get a refund through their credit card holder, you may also be entitled to claim something back through your insurance. flybmi operates from regional airports, including newcastle

and bristol, flying to 25 european cities. the company blames rising fuel and carbon costs for its problems, but in a statement says... the futures of nearly 400 employees both here and abroad are also in doubt. this is flybmi's headquarters at east midlands airport. only one flight due out here today, and that has been cancelled. the advice from flybmi, if you've booked a flight with them, is to consult your insurers or your credit card company, because they can't organise an alternative flight for you. the company blames rising fuel costs, uncertainty over brexit for its problems, but you only have to look at their figures for last year. 29,000 flights, 522,000 passengers. it sounds a lot, but it works out on average atjust 18

passengers on every plane. that's a lot of empty seats. stuart flinders at east midlands airport. earlier, i spoke to former virgin atlantic director paul charles and began by asking him if he was surprised by flybmi's collapse. it's been a basket case, really, in the industry for some years. it emerged out of the carcass of british midland in 2012, which was sold to lufthansa and then to british airways. and then, in fact, what happened was that its new owners tried to make a great strategy of being a regional player. now, its hallmark was in being a regional player but it simply didn't have the strategy on destinations that people wanted to fly to. and it had planes that were very expensive to run and there were not enough passengers to fly on the routes that it was flying. so when you combine all of that and a rise in the fuel price in recent months which has hit several airlines, then it was no surprise that bmi was going to go under.

why would it go under when, for example, flybe have managed to survive? flybe has a different model, a very focused regional operation. the planes, in fact, were re—leased. it renegotiated the leases on the aircraft. but flybmi was never actually a strong brand, so it wasn't able to compete against the bigger players in the industry with a consistently strong brand and strong marketing message. and in the aviation industry, which chews up players like there's no tomorrow and spits them out very quickly if they're not strong players, then in fact, you'll find that flybmi was not able to survive in such a ferocious market. what threat does this raise beyond just the company itself, which has obviously gone under? it's possible that somebody else will step in and try to preserve something from this and bring it out of administration, but leaving that point aside, what about the future of our regional air links in this country? we have quite a number

of regional airports. some of them operate on very, very small returns. it's a really good question, because it throws into question the very essence of regional transport strategy in this country. first of all, i think there will be some airlines that do pick over the bones of flybmi. already you're seeing loganair, which was part of the same group, coming forward to say it's going to run some services that used to be flybmi from the beginning of march. you may see some others — possibly even somebody like virgin atlantic — who say they may be able to do something with a new cooperation with flybe. but from a regional airport point of view, yes, they rely on these tiny players to produce the revenue. a lot of regional airports — as a result of this weekend's saga — will actually be saying, "can we find replacements for the revenues we were getting in from flybmi?" they have huge expansion projects in some cases,

such as at bristol airport, in their planning. and if they can't get these revenues from these regional airlines, they won't be able to expand so fast. you can't go by train as easily, you can't go by road because it is too long a journey for some people who want to do business meetings or short leisure hops. so without these regional airlines in place, it's certainly going to lead to fewer passengers making short trips. paul charles there, former director of virgin atlantic. police are investigating the murder of a 22—year—old man who was attacked in a car in brighton in east sussex. abdul deghayes was found stabbed in a crashed car in the early hours of the morning which crashed. sussex police said he died from his injuries at the royal sussex county hospital. it's emerged that two of his brothers were killed fighting for islamists in syria. his father has spoken of his shock at losing a third son. millions of workers could see their take—home pay fall from april

when the amount they have to put into their pension pot increases. a bbc analysis of earnings suggests higher contribution rates for those in auto—enrolment pensions will hit pay packets, despite an imminent tax cut. here's our business correspondent rob young. building a pension pot, sacrificing part of our wages today to pay for a more comfortable retirement. since 2012, ten million eligible workers have been automatically enrolled in a workplace pension. from april, many of those employees will have to pay a bigger proportion of their pay into their auto enrolment pension pot. according to an analysis of earnings carried out for the bbc, the annual take—home pay of someone earning £15,000 a year will be £49 lower. someone on £30,000 will take home £253 less. in a few weeks' time, many workers currently contributing 3% of their pay will have to put in 5%. this is quite a significant increase relative to what they have

been paying to date, and this is going to affect up to ten million people who have been auto enrolled in the last few years. so, the potential impact of this change is quite substantial. the hit to net pay could have been bigger. a tax cut for most earners — also due in april — will soften the blow. some in the industry worry the hit to pay could lead people to opt out of saving for a pension. but speaking on a recent visit to this electronics factory, the minister in charge said she hoped that would not happen. we need to encourage people to save more, and we need to encourage employers to take more of a role in doing that. and i think that's exactly what we're seeing, and we're going tojust increase it slightly this year. the government regards auto enrolment as a huge success. it says it will closely monitor what happens in a few weeks' time. some in the industry say workers' contributions may have to rise even

further if they want a decent retirement income. rob young, bbc news. the headlines on bbc news: the family of shemima begum — the british teenager who ran away to syria to join the islamic state group — say she has given birth to a boy. president trump warns the us will have to release hundreds of islamic state fighters unless the uk and other allies take reponsibility for those jihadists who came from their countries. hundreds of passengers are left with plane tickets they can't use and hundreds ofjobs are at risk as flybmi collapses. many thanks indeed. good evening to you. there were no major upsets in the fifth round of the fa cup, with crystal palace, swansea and wolves all reaching the quarter—finals with wins today. palace progressed 2—0 thanks to jeffrey schlupp‘s early goal against doncaster, a lovely strike with a little help from a deflection. max meyer's effort on the stroke of half—time doubled their advantage, and the league one side couldn't find a response. palace, remember, finalists

in the fa cup back in 2016. swansea are also there — into the quarter—finals for a second successive season. they fell behind against brentford, though. 0llie watkins with the goal. but two goals in four minutes gave swansea the edge. danieljames with the second of them. brentford had ezri konsa sent off as swansea scored a third through bersent celina, before george byers sealed victory late on with a composed finish. and wolves beat championship side bristol city 1—0 at ashton gate, this one in the early game. ivan cavaleiro with the decisive goaljust before the half—hour mark. city, who'd won nine games in a row in the lead—up, improved dramatically after the break. jay dasilva wasting their best chance as wolves hung on. we played really well.

well organised and good combinations, and a lot of chances that can kill the game and put the game to bed. knowing that after we are going to suffer, bristol city is a tough team, a very good team. and when they start putting balls around the box, it is very tough. and they put us against the ropes. 0ne one more tie to play. celtic are eight points clear at the top of the scottish premiership tonight after a 1—0 win at kilmarnock. have a look at this. scott brown with a late winner in the 90th minute when his shot deflected off alex bruce. jubilant scenes. however, his joy soon turned sour when he was shown a second yellow card for over—celebrating. it still means they maintain their 100% start domestically this year. in the women's fa cup, chelsea are a step closer to succesfully defending their title. they're through to the quarter—finals after beating

arsenal 3—0 in a repeat of last year's final. beth england scored twice for chelsea, but it wasjonna andersson with the best goal of the game with a long—range effort. have a look at this one. chelsea to the next round. elsehwere, super league leaders manchester city won 3—0 at tottenham from the league below. liverpool and manchester united are also through with wins over millwall and london bees. the biggest win, west ham beating the lowest—ranked side remaining huddersfield 8—1. to the welsh 0pen snooker final. australia's neil robertson is leading stuart bingham five frames to three in their best of 17 heading into the evening session. robertson raced to a two—frame lead before piling the pressure on bingham with four wins in the opening five. bingham, the reigning english 0pen champion, ended the afternoon session with his 11th century of the tournament to reduce robertson's lead to two. play resumes at 7pm tonight.

the big—hitting batsman chris gayle will retire from one—day internationals after this summer's world cup. the announcement was made by cricket west indies a short while ago. the 39—year—old will solely concentrate on t20s, a format in which he shines, holding the record for the highest individual score — 175 off 66 balls. super league early pace—setters salford red devils lost to leeds rhinos, who were bottom coming into their match this afternoon. salford managed wins in both of their opening matches, but came unstuck at home, losing 14—46. that win lifts leeds up to seventh. while hull kr beat london broncos 22—12. that, shaun, is all for now. we'll have more in sportsday at 7:30pm. thanks very much. in our top story.

the family believes she has given birth. the news comes as president trump is the main european countries to come hundreds of islamic state fighters captured in syria and put them on trial. a little earlier, macer gifford came into the studio. we cannot use his real name for legal reasons. i begin by asking him about his thoughts on the case. she is certainly unrepentant. i see no evidence that she is any less of a threat now than she was when she first went out. i want the british government to treat her with extreme caution. we can't get this wrong. people's lives are at stake. a lot of people are going to be in the situation where they went out for whatever reason, some idealistic, but the reality of what they have seen and experienced might not only

have an impact, a deep psychological impact, but their views may not have changed. what do you make of donald trump's suggestion that it is down to us as european countries to, if necessary, bring these people back and put them on trial and punish them? i do think we do have a responsibility. what i want to see is the british government reintroduce legislation. at the moment, it's far too broad. we need to tackle isis and their supporters. the priority of government has to be justice to the victims, the thousands of people that have died, but also they have a responsibility to keep us safe. as i said before, we can't get this wrong. ifjust one of them comes back to commit a crime or an atrocity, then would we ever forgive ourselves? the ideology is the question here, isn't it? because what they like to call the caliphate is now shrunk to a square kilometre, if that. 0nce that's all gone, presumably the dilemma is not only ideology, but many of the people disperse, and arguably are more of a threat

than when they are concentrated in one bit of territory. you're right. at the moment, we are defeating the physical islamic state. but actually, the real challenge is easing the tension within the communities. people have seen syria ripped apart. isis have done untold damage to generations of young syrian people, so the next phase of the anti—isis fight — as it were — has to be investment, make people feel liberated, build schools, introduce a new type of democracy to syria that makes all people feel like they are properly represented. won't there not be a reluctance, particularly from the united states, the uk, other european countries, when they see that will involve effectively a kind of making peace, breaking bread with president assad? there's no sign that the assad regime is going anywhere. well, yes, assad is a brutal dictator. he's done terrible damage. much of isis's early growth is down to his decisions. the tragedy is the civil war has dragged on for many years. he's won.

he beat the rebels in aleppo, he's got the backing of the russians. what we need is a pragmatic approach to all of this. we need to get all the parties, including sdf, the group that i was with, in geneva and come up with a solution that actually works for everybody. theresa may has called on conservative mps to put "personal preferences" aside and get her brexit deal through the house of commons. in a letter to every tory member of parliament, the prime minister said "history would judge us all" over the handling of brexit. she also set out what the government would be doing in the coming days to secure a withdrawal agreement that will get parliament's backing. the brexit secretary stephen barclay is due to be back in brussels tomorrow, meeting with eu chief negiotator michel barnier. later this week, the attorney general, geoffrey cox is expected to make a rare speech in which he will outline how

the government will eliminate any legal risk to stop the irish backstop becoming indefinite. and mrs may herself is scheduled to have another meeting with the president of the european commission, jean claude—juncker. earlier, i spoke to our political correspondent pete saull, who explained more background on the prime minister's call for party unity. theresa may is trying to act as a peacemaker. the rhetoric has really intensified ever since that vote in the house of commons on thursday, particular on the former remain side of the conservative party. increasingly exasperated with their colleagues in the european research group of pro—brexit tory mps. theresa may is saying to her colleagues, think about our place in history here, let's come together, put our differences to one side and act in the national interest. she's also insisting that there's not going to be any change of tactics. she still intends to go back out to brussels. she has got a meeting with jean—claude juncker this week, in which she will again try to get the european union to reopen negotiations on that thorny issue

of the northern irish backstop. it's quite interesting to hear today from one of her ministers, the culture secretary, jeremy wright, who suggested that the necessary changes to that backstop could be made without reopening the withdrawal agreement. as i say, i don't think it's the mechanism that matters, it's the objective. if you can get to a place where the potential longevity of the backstop, the potential that the backstop lasts forever, can be adequately dealt with, that's what we are all seeking to do. that's what parliament have been very clear that it wants. it'll back this deal if we can do something about the backstop. the mechanism is what we are discussing at the moment, but parliament needs to give the prime minster the space to have that conversation with brussels, to see what we can achieve, and if we can do something about that, i think it's very clear that parliament will be prepared to support this deal. although it was not entirely explicit from jeremy wright, the idea that

you could sort this issue out without reopening the withdrawal agreement probably will not go down well with a lot of conservative brexiteers who would like the government to take a pretty hard line on this. also interesting to note today that that fragile truce in the tory ranks is indeed very, very fragile. the defence minister saying today that if it came to it, he thinks there should be a free vote on whether no—deal brexit should be taken off the table. he thinks, frankly, that would be a catastrophe — again putting himself very much at odds with the other wing of the tory party. that raises the possibility of some of these people having to resign or be sacked if they stick to their word on this and the government won't give way on leaving no—deal on the table. what about labour? in a sense, labour could be the cavalry for theresa may riding over the horizon, couldn't they, if they were willing to lend her enough votes to get her deal through and cancel out the hard line brexiteers and the dup? labour have made it clear

that they will not accept a brexit deal unless the uk joins a customs union with the eu, but it is also fair to say that labour has its own divisions over brexit, of course, and a lot of talk around westminster about a potential rupture within the labour party. we know for some time that some backbenchers have been unhappy with the leadership. and it's notjust brexit. it's anti—semitism issues, venezuela more recently, that has caused some concern. the shadow chancellor was asked about this this morning on the andrew marr programme, and he said that all of that potential split would be pretty counter—productive. we really do not see why there is a need, because all the issues that people have raised is the potential for a split, we're dealing with. 0n brexit, we are holding the party together. those saying we'll split without a people's vote, we have still kept that option on the table and it might come about. why split over that? that's ridiculous.

this debate continues on social media, because labour activists have been trying to persuade mps to sign up to a pledge which basically says that an mp would work for the achievements of a labour—led government under whatever leadership members elect, and they accept a labour—led government is infinitely better than any other election outcome. lots of labour mps have signed up to this pledge, put forward largely by supporters ofjeremy corbyn, but other labour mps notably have decided not to sign up, some making it clear that their pledge is their membership card which they have held and worked hard for for many years. also today, a former, quite big figure in the labour ranks, a former vice chair of the party, has decided that he is resigning his membership after 28 years, saying that it pains him to see what the labour party has become. us airforce transport planes carrying humanitarian aid for venezuela have landed at the colombian border, where food and medicine is being

stock—piled for distribution. president maduro has refused to allow the aid in, accusing the us of trying to organise a coup. american officials say the aid had been requested by the venezuelan opposition leader, juan guaido who declared himself interim president last month. jon ironmonger reports. it is an operation that is 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 shipment — not only from the united states but we know that 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.

and 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, three million venezuelan migrants have fled the country since 2015. us aid drops are intensifying the stand—off with nicolas maduro,
