mosul? the us says it is now investigating, but admits coalition forces were carrying out air strikes where many people have been killed. the fight to retake the city from the group calling itself islamic state began last october. the iraqi army is being supported by us—led coalition airstrikes. they have reta ke coalition airstrikes. they have retake in all of eastern mosul and have now made key gains in the western half of the city. they are now closing in on the densely populated old city. this area in red is still being held by the so—called islamic state. the united nations says it is stunned by the terrible loss of life caused by recent airstrikes. eyewitnesses say many victims are buried under the rubble. other residents say is is using civilians as human shields, but blamed indiscriminate airstrikes for many of the deaths. translation: blamed indiscriminate airstrikes for many of the deaths. translatiosz is iraqi and coalition aircraft is, is snipers positioned themselves on top of buildings. when these

buildings are hit, everybody is killed, the sniper and the families who live than that. —— live there. jeremy bolan sent this report. thousands of people have arrived, have walked out of those parts of mosul still controlled by islamic state. they need food, they need water, they need shelter. it's a massive humanitarian challenge, and not nearly as big as the one that may literally be coming down that road in the next few weeks. from where the black smoke is, which is where the islamic state positions are here in mosul. this is very much a theatre of war. the people who have been coming in have been talking about what they have been through.

they have talked about air strikes that have come in in the last few days and killed, as well as killing people from is, have killed hundreds of civilians. they have complained that the jihadists have used them as human shields. but they have also, in tears and anger, spoken bitterly about the effects of air strikes on civilians. i spoke to multiple witnesses who said that there are perhaps hundreds of bodies still lying in the rubble, that people cannot get to. if you take it all together, the effects of the war, the wounded and the dead, military and civilians, and the massive humanitarian needs

of the people displaced by the fighting, it comes together as a great big humanitarian emergency. it is worsened by the fact that it is happening in a country which was already broken into pieces by war. it isa already broken into pieces by war. it is a huge challenge. it is really ha rd to it is a huge challenge. it is really hard to think of a bigger one anywhere in the world at the moment. jeremy bowen, bbc news, mosul. i have been speaking to kenneth roff from human rights watch. i asked him if he thinks a full and just investigation will be conducted by the us. we don't know. this, and have to say, is part of a pattern that we have seen in the last couple of weeks. there have been american attacks which have caused substantial civilian casualties in rural aleppo and outside raqqa in syria, and now this awful tack in western mosul in the iraqis up we know that president trump came into office and said he wanted to ease

the rules of engagement that the obama administration have used. he felt they were too concerned with preventing civilian casualties. the pentagon insists the rules have not yet changed, but something seems to be happening. we know, for example, there does seem to be a push down there does seem to be a push down the chain of command to apply those rules of engagement. so lower—level officials are making decisions which, under obama, were made by more senior people. frank, we also don't know how those lower officials are taking the signals from the white house that it is time to be so worried about civilian casualties. —— time to not be so worried. i think it is urgent to get to the bottom of what is going on and quickly tighten up the way that us forces are behaving. there is no evidence yet, is there, that the us and its coalition forces are responsible for any of these airstrikes? well, the united states has come out and said that it does believe it was responsible for the airstrike that hit western mosul.

they made that announcement today. they made that announcement today. the force may say they did not know they were civilians on the ground, but why didn't they know? why weren't they observing? it is the real question. it is worth noting the claim that isis is using civilians as a human shield, that may well be true. there is certainly evidence of that. but that doesn't excuse an evidence of that. but that doesn't excuse an attack of this sort. the us should have been closely monitoring the situation, and frankly, having a few snipers on top ofa frankly, having a few snipers on top of a roof does notjustify destroying an apartment building if you know that there are civilians in the basement. maybe they didn't know, but why didn't they know? this goes back to the question of how careful they are being. why are they deviating from what was sure much more successful practice in avoiding civilian casualties under the obama administration? this is what we have to look at quite urgently. even so, this part of the operation is the most difficult part, the old city, the most in part of the operation.

—— most dense part. isn't it understandable they would have been casualties? well, of course you expect casualties. but it is the duty of the attacker to minimise civilian casualties. it is worth saying that this was not a close call. this was not a civilian who happened to run in front of a firefight. this was a bomb dropped ona firefight. this was a bomb dropped on a series of residential buildings. we do not know what the us knew, but we do know now, after the fact, that there were perhaps hundreds of civilians harbouring in those buildings. so the real question is, why didn't the us know? why did it feel that it was sufficient that there were a handful of snipers on the roof to justify an attack of this sort, without being more careful about civilian casualties? yes, urban warfare is difficult, but it doesn't mean you can throw the rulebook out the window. you still have to do everything feasible to spare civilians the hazard of war. kenneth roth, reporting there from human rights watch. in rome, eu leaders have stressed

the need for unity in a celebration marking 60 years since the treaty of rome was signed. that to the founding of the original european union. 27 eu countries signed a new declaration, but significantly, the uk was absent. damian grammatik as reports from rome. this gathering was the eu's concert to brexit. 27 leaders from across europe returning to rome, to where the first steps to the creation of the first steps to the creation of the eu were taken, to reaffirm their vows the eu were taken, to reaffirm their vows of unityjust as the uk prepares to quit. i do think that brexit, the exit of britain, is a tragedy. the leaders were marking exactly 60 years to the day from the signing of the treaties of rome, in the very same room where they stood now. back then, just six nations match to create an economic partnership. countries who had

fought each other putting aside differences to rebuild europe. today, in a lastly expanded union, 27 prime ministers and presidents signed a new rome declaration, pledging to continue to co—operate, even as they face challengers all around. they are countries are emerging from the economic crisis, but there are fears about jobs, terrorism, migration, and divisions amongst the leaders too. europe as a political entity will either be united or will not be at all. only a united or will not be at all. only a united europe can be a sovereign europe, in relation to the rest of the world. and only a sovereign europe guarantees independence for its nations, guarantees freedom for its nations, guarantees freedom for its citizens. and on this anniversary there were marches around europe today by eu

supporters. this was in london, more than 20,000 estimated to have taken part. and in rome, the gatherings we i’e part. and in rome, the gatherings were small. what worries eu leaders is that in the wake of brexit, their opponents, eurosceptic nationalist forces, a re opponents, eurosceptic nationalist forces, are energised now. with this summit, eu leaders are trying to find a new impetus for their project, to confront brexit on the other challenges they face. the problem they have, how to rekindle enthusiasm for the eu across europe. meanwhile, thousands have been taking part in protests here in london against the triggering of article 50, which is the official pi’ocess article 50, which is the official process of the uk to leave the eu. the marchers want britain to remain in the eu and to fight a hard brexit, which would mean britain leaving the single market. while a pro— european family also took place in berlin, where those taking part held up banners saying that the eu is not dead, reflecting fears that

brexit could result in more countries leaving the 27 nation bloc. in rome itself, police clashed with anti—eu demonstrators. officers seized iron bars and knives, and there were scuffles in the street. around 1000 people have marched through the streets of hong kong in a pro—democracy march ahead of sunday's chief executive election. lies, coercion and whitewash were just some of the words printed on the banners. people are furious they will not get to decide who their next leader will be. that role will be fulfilled by hong kong's 1200 be fulfilled by hong kong's1200 seat election committee, a mostly pro— beijing body. it will choose from those candidates to succeed the outgoing leader, steve either. —— see outgoing leader, steve either. —— see why long. —— cy leung. outgoing leader, steve either. —— see why long. -- cy leung. this is not democracy. this is a small circle election. we would like to

have an assembly, we want universal suffrage. let's get some other news you. security forces in bangladesh are continuing to surround an apartment block the north—eastern city of sylhet, where is alarmist militants have been holed up since friday. —— islamist. nearly 80 hostages were rescued on monday. in a show of the fires, extremist set off bombs killing at least four back people in a large crowd which had gathered to watch the siege. police in london say the westminster attacker, khalid masood, who killed four people on wednesday, acted alone. khalid massoud drove a car into civilians before stabbing a police officer to death outside parliament. he was later shot dead. china has lifted a ban on meat imports from brazil imposed after federal police closed plants and accused senior inspectors of taking bribes to approve on safe produce. —— unsafe. more than 20 countries

have put restrictions on brazilian meat in the past week. a ban on laptops and tablets in hand luggage on flights from turkey and several other middle eastern countries have come into effect. it is on flights to and from the us and uk. officials say it is because of an increased risk that such devices could contain explosives. but turkey has responded angrily, describing the move as unfair. wrapped up, ready for the hold. security at this airport in istanbul has just got tighter. no laptops, ta blets has just got tighter. no laptops, tablets and e readers allowed in hand luggage on flights to the us and the uk. some passengers preparing for a long journey were not impressed. this airport is so secured. the security level is so high, compare to other airports in the rest of this part of the world. so why are they doing this from here? if you see it like this, you

will say everybody can be a terrorist. it is not respectful of turkish people. i think it is not good. the countries affected by the uk laptop ban are turkey, lebanon, jordan, egypt, saudi arabia and tunisia. the us ban covers turkey, morocco, jordan, egypt, the united arab emirates, qatar, saudi arabia and kuwait. what has been worrying the us and the uk is a device like the us and the uk is a device like the one that blew a hole in the side of the somali airliner last year. a small bomb in a laptop. only the bomber was killed. the theory is that a small device going off in the hold, rather than the cabin, gives the pilot a better chance of successfully leading the plane. but turkey has urged the lifting of the ban as soon as possible, saying it creates unfair competition. translation: we respect security measures. we must take security measures. we must take security measures. security measures are measures. we must take security measures. secui’ity measures are more important than passengers' comfort.

but if you impose security measures in one place and do not implement them in another place, we would interpret that differently. we would think that there are other intentions behind this ban. for business travellers wanting to do work, forfamilies business travellers wanting to do work, for families wanting entertainment, it is going to be a big and for many unpopular change. there is no end date for the ban, but officials say that security must be the top hierarchy. —— priority. uber technologies has suspended its pilot programme for driverless cars after a vehicle equipped with the technology crashed on an arizona roadway. the accident is the latest involving a self—driving vehicle operated by one of several companies experimenting with them. no one was seriously injured. stay with us on bbc news. still to come: as thousands of migrants remains stranded on greek islands, we look at the growing challenge of handling migration at the edge of europe. let there be no more war

or bloodshed between arabs and israelis. so proud of both of you. with great regret the committee have decided that south africa be excluded from the 1970 competition. streaking across the sky, the white hot wreckage from mir drew gasps from onlookers in fiji. this is bbc news.

the latest headlines: the us says it is investigating whether coalition aircraft carried out strikes in an area of mosul where many civilians have been killed. as the eu celebrates its 60th birthday in rome, thousands take to the streets to celebrate, and to protest. president donald trump put on a brave face on saturday after accepting that he failed in his election promise to overhaul president obama's health reforms. republicans withdrew their health—care bill shortly before a vote in congress, after it became clear they didn't have enough votes to get it through. mr trump says he's learned a lot during the process. he blames the minority democrats for the failure. us vice president mike pence told a crowd in west virginia that congress wasn't ready to pass

the legislation but both parties will come together and end obamacare. yesterday wasn't a victory for the american people, it was a victory for the status quo in washington, dc, and it was a victory for the disaster of obamaca re. but i promise you, that victory won't last very long. applause the american people want obamacare gone and as the president said today, don't worry america. he just tweeted this morning. obamacare's going to continue to explode and when republicans and democrats finally decide to come together and repeal and replace obamacare, we'll be ready to get the job done. gwenda blair is a political author and has written a biography on donald trump. she joins us from seattle.

you have studied him. how will donald trump take this failure? well, he's —— he would prefer to be winning and getting even with anyone who opposed him, but he didn't win this round, so what to do about the getting even part? at the moment he seems to have decided not to go for getting even, at least not publicly. so he did not go after speaker of the house paul ryan, he did not go after the house freedom caucus, the ones who said they were not getting onboard, he said instead it was the fault of the democrats, which was a little laden because of course the democrats weren't going to get on—board something that was going to replace obamacare. —— a little lame.

he also said that he didn't promise within 64 days, the this is the 64th day of the administration, which we could also call lame. but the important thing is he didn't get even this round and that's because he is looking for the lawn game here andi he is looking for the lawn game here and i think getting even was not going to serve him. —— long game. what serves him is what he has a lwa ys what serves him is what he has always focused on. you say he is shrewd. interesting how he went about this. he wanted to force through the vote on friday and push people to vote for it. how do you think he is adapting from being this property magnate to being a politician? well, his m0, in real estate and casino gambling, always to get himself and one other guy in

the same room and then proceed to get the best possible deal to extra ct get the best possible deal to extract as much as he could for himself, to lead as little as possible for the other guy, in other words bullying. but at the freedom caucus he had two dozen other people who were very used to bullying in the room and they didn't back down. so he had to readjust to that one. but he is an adaptive guy. in his first... we've got to remember, this isa first... we've got to remember, this is a guy who had four corporate bankruptcies and managed to emerge not losing a dime, with his brand evei’ not losing a dime, with his brand ever enhanced, and being able to write off his own personal income tax for many years later against those losses. he is very shrewd. he is going to keep looking for the loopholes, the way around, and i don't dig anybody should count him

out yet. —— i don't think. but he did have to back away from his usual response, which would be to get even. and we should look for the next destruction, let me add. that's the thing to watch. what will be the next distracting thing that will pull our attention away from what just happened with the healthcare bill? thank you very much for being with bbc news. president erdogan says turkey might hold a brexit—style referendum on whether to pursue eu membership. turkish attempts to join the eu have stalled since 2005. his comments come a year after the eu and turkey agreed a deal to stem the flow of migrants entering europe. but bureaucratic delays have left thousands stranded. paul adams sent this report from the greek island of kos. one year ago these waters fell silent. a deal was struck,

enforcement follow. europe breathed a sigh of relief. but it is not ovei’. a sigh of relief. but it is not over. on this island the camps are overflowing once more. a surge of new arrivalsjoining overflowing once more. a surge of new arrivals joining those who have been trapped here for months. abdullah arrived here today the eu — turkey deal went into effect. one day earlier and he could have moved on, but he has been stuck for over one year. long enough to draw unfavourable parallels with life back home. ijust unfavourable parallels with life back home. i just want to live like a human being. here, they let you live because there's no to kill you. but they kill your hope, they can your dreams. the government run campy was supposed to be a model reception centre, but secret filming from inside shows are placed migrants call the cage, where new arrivals are held for the first few

hours. an intimidating first glimpse of europe and the start of a long bureaucratic process that seems designed to halt them in their tracks. people that are expected to spend herejust a tracks. people that are expected to spend here just a few days as stranded here for months, which has impacted on the psychology of the people. they don't have the perception that tomorrow the situation will be solved. they think this thing could go on for years. the damage is not hard to find. this man left aleppo last year. in january he learned his mother and sister were killed in an air strike. he feels utterly lost. i want a safe country for me because i have lost everything. everything... future and family. my life. the principal at the heart of the eu — turkey deal is that turkey, just over the water, is

a safe place for refugees and other migrants to return to. the syrians in particular dispute that and say that turkey is not safe for them. a greek court is due to rule on this soon. much will depend on the outcome for the migrants stuck on it islands. clarity is badly needed. as the philippines marks earth hour, star wars fa ns as the philippines marks earth hour, starwars fans in as the philippines marks earth hour, star wars fans in manila engaged in an historic fight to save the earth. around 60 people from philippine lightsaber guild marched and held lightsaber duels to urge filipinos to be heroes for the environment. one of the event's organiser stressed on the importance of its message. don't forget you can get in touch with me on twitter. good morning. it was a lovely start

to the weekend and there is more sunshine to come on sunday. these we i’e sunshine to come on sunday. these were saturday's blue skies, taken by a weather watcher in aberdeenshire. here, the temperature rose to 19.1 c, making it the warmest day of the year so far. closely followed by west wales, northern ireland and into cumbria. similar temperatures again on sunday. but it is pretty cold out there at the moment, especially underneath the high pi’essui’e, especially underneath the high pressure, where we've got no wind to speak of. maybe a couple of mist and fog touches just shortly that. not as cold to the south due to the wind, but across the northern isles where we have a touch of frost already, especially chilly in the glens of scotland, parts of northern ireland. it will warm up quickly in the sunshine. a lot of sunshine, almost wall—to—wall. still clouding shetland, perhaps orkney, little bit of light cloud across the english channel. on the wind still blowing

in southern parts of england and wales. light winds further north. lots of sunshine across the bulk of scotland, away from the northern isles. the highest temperatures in scotla nd isles. the highest temperatures in scotland further west in western scotland. we could get up to 80 degrees in parts. 18 possible in the north and west of wales. generally about the need teams. the edge taken off the sunshine by the stronger winds in southern england. it could bea winds in southern england. it could be a touch cooler than saturday in devon and cornwall and temperatures pegged back on the coast with the onshore breeze. a lovely evening if you are heading to wembley for the football on sunday. but once the sun goes down we could find those temperatures falling very quickly. that's not quite so though, because on monday there will be a bit more cloud around, especially moving northwards into northern england and southern scotland, northern ireland. still a lovely day in the north—west of scotland. for most of england and wales there will be sunshine. not as windy in the south. still 16— 17 degrees. not as warmer we have a

cloud. things gradually change as we look towards the south—west. we push away the high pressure that's keeping it fine and sunny and we will introduce some showers perhaps across northern ireland, wales, or western parts of england. further east it may well be dry and across scotla nd east it may well be dry and across scotland it is largely dry, but more in the way of cloud here. but the slowest thing we will develop over the weekend. cloud increasing. the chance of some rain as well. but we will have the wind from the south, so will have the wind from the south, so with the sunshine it will still be on the warm side and it won't be as cold as —— at night. the latest headlines from bbc news. the us says it will investigate after confirming coalition aircraft did carry out strikes in an area in mosul where many civilians have been reportedly killed. there's growing concern over reports of air strikes causing mass casualties. as the eu celebrates its 60th birthday in rome, thousands have been celebrating and protesting.
