in a protest against new police powers, it was soon police themselves who became the target. vans and a police car set on fire, fireworks thrown into the crowd as around 1,000 protesters gathered in bristol city centre in what has been, police say, the worst violence the city has seen in years. there's a row of police blocking off what is the central police station here in bristol, but you can see at the end of the road, they've also blocked off now the end of this city centre street, but also the side roads too, and they're doing it from behind, but there are still about 1,000 people here and now they are being left with nowhere to go. protesters here holding banners, concerned, they say, that the uk is becoming a police state. the kill the bill march started in the early afternoon, but as night fell, the clashes began. projectiles thrown at officers in riot gear. we saw several people with head injuries being helped from the crowd. i think it's horrible, and i agree with the cause of the protesters, but i don't

think this is going to do anybody any good. ——of the protesters, but i don't think this isn't going to do anybody any good. several officers have been injured, some reported to have broken bones. the chair of the avon and somerset police federation said people's right to protest had been hijacked by protesters hell—bent on violence. heavy rains have triggered the worst floods for a century in parts of australia. thousands of residents in the state of new south wales have been told to leave their homes. forecasters are warning that more rain is expected. to give you an idea ofjust how saturated the ground is, take a look at these pictures filmed at 0xley island, about 250 kilometres north of sydney. the water simply has nowhere to go, and that's led to images like this — a house literally floating away. it's believed it belonged to a couple who were due to get married on saturday. the river is peaking nearly six metres above normal. it's already burst its banks.

things are so serious that prime minister, scott morrison, has put the australian defence force on standby. well, communities along the hawkesbury river near sydney risk losing their homes and vital utilities could be disrupted for months. earlier i spoke to resident lucy hughes — floodwaters have separated her from her family. currently on the city side of the hawkesbury river and my family, my parents, my brother, they're currently in north richmond. my parents live in sackville which is just down from windsor bridge. and what's happening? what's the threat level to your childhood home, the home that you grew up in? currently it's major flooding. our home is currently sitting on its own little island, it's currently surrounded by water. my parents, my brother, we tried to take what necessities, what sentimental stuff that we could, they evacuated down to north richmond,

which is also in a majorflood zone as well. we can just see the pictures from you, actually, just seeing how close the water is to the house there. just give us a flavour of what emotions you are going through at the moment. my whole family is devastated. we are beyond the level of shock. those photos were taken about an hour ago and this weather and the flood levels are only expected to rise even more, and so we have had to come to the realisation and acceptance that the water is going to rise and it's going to rise into ourfamily home, into a property that's been in ourfamily for two generations. there's a lot of memories in that place and a lot of valuable, sentimental things that we own that we are going to lose and my parents are going to lose. we are going to have to start over again and we are currentlyjust in a mood of complete devastation.

my thoughts of course are with you and your family as you try to just wait and see what happens, what have you been told about what is going to happen in the days to come and weeks to come? we only know what we have heard from the news as well. i have been refreshing floodwater websites hourly to get flood levels. my brother and father returned back to the property by boat because it is the only way to find out what is happening and what is going on in the area and as you can see those photos were only taken an hour ago after having access to that area by boat. so for now it is just wait and see. we know the next 2a hours is going to be more water. the warragamba dam in sydney is continuing to spill and dump water equivalents of sydney harbour into this river system and the level of water is only going to rise so right now we are holding onto the hope for a miracle because miracles can happen

and it is all we can hope for. let's get some of the day's other news the trial of michael kovrig, the second of two canadians detained in china for more than two years, is underway in beijing. the hearing comes days after the closed—door trial of michael spavor, both of the men were detained in apparent retaliation for canada's arrest on a us extradition warrant of huawei executive meng wanzhou. the us defence secretary, lloyd austin, has called for a reduction in violence in afghanistan during a brief, unannounced visit to kabul. speaking after talks with president ashraf ghani, mr austin, refused to be drawn on whether the biden administration still planned to withdraw troops from afghanistan by may, as stipulated in the us agreement with the taliban last year. nawal el saadawi, the pioneering egyptian doctor,

wejoined sergeant roger rich as he patrolled the vast scrubland along the river that separates texas from mexico. before the new president took office, we didn't have these types of numbers coming across. we see unaccompanied children all the time. we caught one on monday that was coming in from bolivia, that was ten years old, by himself. as every day ends here, a waiting game begins. soon, emerging from the banks of the rio grande, eight scared, bewildered and exhausted boys. they left guatemala weeks ago, coming without parents or passports, just plastic packages protecting birth certificates and crucial phone numbers. so, he's going to somebody who's going to help take care of him. milken is 17. he tells me he came here

because he wants to study. at home, there's only crime and gangs. the boys are directed to this temporary processing site from which we were evicted and told we couldn't film. it's likely some will be sent here. dallas convention center has been converted to hold up to 3,000 unaccompanied children. media are not allowed in. families are coming too. some say they come because the cartels that control the mexican side are telling those desperate to hear it that the new president has opened the border. with this new administration, numbers are starting to go up because they feel that possibly they have a chance to be heard, to be allowed to be inside. the previous administration had the same problem, not because they were very kind and wanting to welcome everybody but it was because they had hopes that "maybe i'll get in before he kicks us out". why did you decide to leave your mum, your brothers? milken tells me he's run from violence and poverty.

he doesn't even know who president biden is. all he knows is how hard it was to say goodbye to his family. i give him my phone so he can call the uncle he's desperately trying to reach. but he's thousands of miles away in seattle. these boys may have made it to the promised land, but their journey is far from over. their future now as uncertain as the day they left home. sophie long, bbc news, the rio grande valley. stay with us on bbc news, still to come... the largest asteroid to pass earth this year provides the chance to see a space rock from the dawn of the solar system.

this is bbc world news, the latest headlines... violent clashes on the streets of bristol, after thousands protest against proposed police powers to control british demonstrations. mass evacuations — as south—east australia is struck by the worst floods in a century — the prime is struck by the worst floods in a century. the prime minister offers emergency funds to those affected. in syria, seven people have died in an artillery strike on a hospital in a cave in a rebel—held town in the aleppo region. 14 medics were also injured. turkey's defence ministry said a child was one of those killed in the attack, which it blames on forces backed by the syrian government. mark lobel�*s report contains some distressing images. the remains of a hospital. once a place to get better.

it suddenly became a target, shelled by syrian government backed forces. during the shelling, the hospital director runs for cover. urging people around him to keep calm. he already knows of seven casualties in his hospital, and that it's no longer safe. translation: stay calm! stay calm! as you can see, the shelling of the hospital has been going on until now. we came here for our own safety. we asked the medical staff to leave. the hospital is out of service. there is meant to be a ceasefire in this area. this hospital's co—ordinates have been shared by the un to avoid making it a target. but it's the fifth such attack this year according to the international rescue

committee. also struck, this fuel depot in bab al—hawa near the turkish border. crucial rebel fuel supplies decimated by suspected russian jets. the human cost of this ongoing war is all too real. syria and its ally in this conflict, russia, says it only targets militant islamists, not civilian areas. but the un says this attack on a hospital is an alarming development which has devastated those burying their dead. now to the southern philippines and an area rarely visited by the western media. the newly established

bangsamoro autonomous region of muslim mindanao is the product of a recent peace deal between separatist fighters and the philippine government. after decades of conflict, the moro islamic liberation front is now transitioning to politics, helping to establish a fledgling regional parliament in return for the decommissioning of firearms. but with other factions still at war with state forces, can the peace hold? 0ur correspondent howard johnson visited the region, with the westminster foundation for democracy, to take a closer look. the dimaukom mosque was painted electric pink to promote peace and love in an area beset by violence. we've come here to meet umi and comenie, two former fighters of the separatist group the moro islamic liberation front. i ask umi why shejoined the group. translation: i saw my parents being hit by some soldiers. - they killed my uncle who was tending to his water buffalo on his farm when they passed by. another relative

was also killed. they threw their bodies into the river. the bangsamoro, meaning nation of the moro people, say that this is part of decades of religious discrimination from catholic—dominated manila. first established as the moro national liberation front, the milf split away to form the region's most dominant insurgency in the 1990s. the group that once trained with al-qaeda now say they reject that violent ideology, hoping to build a better future for their people through a fledgling regional parliament. translation: the ethnic cleansing back then - was during the times of my parents. the difference now — i am myself an employee of the government. i became one of the instruments to continue to fight for the bangsmoro cause through the government. and it appears that the peace is holding. the milf have publicly decommissioned hundreds of firearms. the organisation international alert say overall violence

in the region has declined year on year since 2016 but intensified in some localities. although the peace process appears to be taking root, there are factions here that never wanted to be part of it in the first place. so that's why we're travelling with a police escort because in recent weeks, there have been roadside bomb attacks, skirmishes between local clans, and there remains a kidnapping risk for westerners like me. but in the main market of the regional capital cotabato city, there's a palpable sense that things are changing. translation: we want peace. we muslims and christians come from the same place. stop the war, stop the misunderstandings. the peace deal agreed full elections for parliament next year but the region's chief minister says he'd like to push back the vote until 2025 because of setbacks caused by the pandemic. what do you say to those critics who say, "could this be "seen as a power grab?" there's nothing wrong

in the extension because we see the failure to properly implement the agreement will result in failure of the peace process. for years, umi and comenie were enemies of the state. a family outing like this would have been impossible. but now the police turn a blind eye to them. the mosque's appeal for peace seems to be working. howard johnson, bbc news, maguindanao. the largest asteroid to pass by earth this year has just reached its closest point, giving astronomers an opportunity to observe a space rock that formed at the dawn of the solar system. the asteroid — which was first discovered 20 years ago — is about 900 metres in diameter. the american space agency nasa says that at its nearest point, it will still be two million kilometres away. jeffrey hoffman is a former nasa astronaut, who is now a professor of aeronautics and astronautics at massachusetts institute of technology. he told me what these near—earth asteroids could mean.

well, knowing how big it is, it is over half a kilometre asteroid, so i mean, it's a planet killer, if it were to hit the earth. whether it's too close or not, as long as it misses us, it is far enough away. where are we on mapping all these objects out there which could actually hit us and do us some damage? well, it's been a long term project of nasa to try to map all of the so—called near earth asteroids, down to a certain size. i don't know, something on the order of 150 metres. but you know, this big asteroid is not the only one passing by us today. there's another one,

the big one is about two million kilometres, another that is only about 30 metres across, which is going to miss us by about 1.5 million kilometres. that is closer! it can do a lot of damage and it was only discovered two days ago, last friday, so there are still surprises out there. that's worrying that it was only discovered two days ago and there are still surprises of that size out there! things can come at you out of the sun, fighterjets in the movies, in wars, what we really need is a dedicated satellite which will be able to do an even deeper survey of these objects. nasa is in fact working on this. do we have a plan in place if we discover one is coming a bit too close for comfort?

well, if you can get it early enough, there are many things you can do. if it's far enough away from you and you know about it in advance, and you can fly up to it with a spacecraft and give it a little push, that's enough to change the orbit so it will miss us. but if you only see it two days before it's going to hit us, unfortunately, there is probably not much we could do. we have been warned! and finally wales has found itself welcoming an unexpected visitor. a giant walrus has been spotted in pembrokeshire, thousands of miles from its home in the arctic circle. it's thought it's the same animal that was spotted off the coast of county kerry in ireland last week. biologists believe there's a chance it fell asleep on an iceberg and was then carried south.

no chance, he knew exactly where he was going, the greatest country of them all! hello there. it looks like our weather pattern is going to change over the week ahead. for the past few days we've had quiet, settled weather. it's been warm when the sun has been out. high pressure in charge. let me show you the upper level winds, the jet stream, that's the position of the jet stream and you can see how undulating that pattern is right now. but as we head into the week, we get more of a zonal flow. west—to—east wind coming in and bringing in air from the atlantic, and lower pressure means the weather is eventually going to turn more unsettled. fairly quiet at the moment, still. we've got a chilly start underneath those clearer skies. more cloud coming into northern ireland, north west england and especially western scotland. a little light rain or drizzle here. elsewhere it looks like it's going to be a dry day. some sunshine at times, light winds, temperatures again peaking at 13 or 14 celsius through the midlands, south east england, east anglia and the north east of scotland. moving quickly onto tuesday,

and we've got a fresher breeze picking up. south or south—westerly wind, looks like it's going to bring in a lot of cloud. maybe some dampness in the air out towards the west ahead of a band of rain that comes into northern ireland, western scotland later. temperatures again are perhaps 13 or 14 in the east where skies should be a bit brighter. we start to see the weather changing, though from midweek. that weather front bringing rain down from the north west into england and wales, not going to amount to very much at all. still dry in the south east for a while. after that band of patchy rain, we get some sunshine and then the weather turns wetter in the north west, especially into western scotland. the winds are bit stronger here. elsewhere, the winds should be fairly light which is why that band of cloud and rain isn't moving very far. temperatures not changing very much, again, on wednesday. the winds continue to pick up though, i think, during thursday and we start to see some mixture, really, of sunshine and showers. some wetter weather, though, a band of rain coming

into northern ireland, into western scotland through the day. and temperatures of 12, 13, maybe 14 celsius — near normal for this time of the year. but as we head towards the end of the week, we've got low pressure in charge. that's coming down from greenland, settling between iceland and scotland and that's going to bring colder air across the uk together with some much stronger wind. and we're looking at some bands of rain or showers and it's cold enough for those showers to be wintry over northern hills, perhaps even down into parts of wales as well. temperature wise, 7 celsius in the north, maybe making double figures in the south east.

this is bbc news, the headlines.

several police officers have been seriously injured during violent protests in bristol. thousands of people gathered to oppose the uk government's proposed police and crime bill — which would give forces in england and wales more powers to curb protests. clashes then broke out at a city centre police station. parts of new south wales in australia are suffering their worst floods in a century. torrential downpours have caused dams to overflow and river levels to surge. around a thousand people in the western suburbs of sydney are the latest to be urged to evacuate their homes. city officials in miami beach in florida have approved an extension to a state of emergency after thousands of tourists descended for the annual spring break holiday, risking the spread of coronavirus. the decision means that a night—time curfew will continue for at least three weeks. now on bbc news, it's time for hardtalk.
