rescue teams in colombia are searching through mud and debris for survivors of huge mudslides which have killed more than 250 people. hundreds more are injured or missing. the mud engulfed the town of mocoa, where rescue efforts are being hampered by bad weather. keith doyle has the latest. a wall of water, mud and debris swathed large parts of the town of mocoa. thousands have lost their homes, hundreds have lost their lives. this mountainous region has had unusually heavy rain in recent months. further downpours caused the mocoa river to unleash a devastating mudslide. witnesses say people were running for their lives as the mud pushed cars into buildings and ripped trees from the ground. streets were left littered with huge

boulders and people have been picking through crumbled buildings, trying to find the missing and salvage any possessions. hundreds of people are still missing, many of them children. lists of their names and ages are scoured by anxious relatives. translation: we have lost a baby who has gone missing. the rest is as you can see. a little baby, we can't find him anywhere. translation: we do not know how many deaths there are going to be. we're still searching, but the first thing i want to say is that my heart, our hearts, the hearts of all colombians, are with the victims of this tragedy. many roads have been washed away or are blocked, making it difficult to get aid into the area, which is without power and running water. troops and volunteers are searching for survivors. heat—seeking cameras and drones are being flown over the debris. the red cross says it's crucial to find survivors within the first 72 hours. three days on, the death toll

is expected to rise. keith doyle, bbc news. six people are being questioned over an attack on an asylum seeker who was standing at a bus stop in south london. the 17—year—old boy, who is kurdish—iranian, was left with a fractured skull after being subjected to what police say was a savage attack, in croydon on friday night. the teenager remains in hospital in a critical condition. lydia wilkinson has paid tribute to her mother and younger brother, who were stabbed to death in their home in stourbridge earlier this week. she laid flowers outside the house, accompanied by her boyfriend. she said her mother, tracey, had always put others before herself. 23—year—old aaron barley, of no fixed address, has been charged with their murders, and with the attempted murder of lydia's father peter. he is known to the family and will appear in court again in the morning.

lydia wilkinson arrived at the family home where her mother and brother were killed clutching flowers. she weighed them alongside floral tributes left by friends and family. each message, including her on, described how much mother and son were loved and beauty contest. overcome by grief, she was comforted by her boyfriend. the house remains a crane seen. it was here that her mother and brother, seen on the left—hand side of this photograph, we re left—hand side of this photograph, were fatally attacked. their father was left critically injured, but is now ina was left critically injured, but is now in a stable condition in hospital. today, a 23—year—old homeless man appeared at court, where he was remanded in custody and charged with murder and attempted murder. in a brief written

statement, lydia wilkinson described her brother as a fun loving boy and her brother as a fun loving boy and her mother as someone who had was put others first. the family have asked for procedure ring this difficult time. —— privacy. the government is facing pressure to guarantee that migrant workers will still be able to work in the nhs after the uk leaves the european union. a cross—party group of mps is warning that brexit will cause a critical shortage of doctors and nurses. it comes as the defence secretary, sir michael fallon, declined to rule out the possibility that freedom of movement could continue until the next general election and beyond. ellie price reports. the brexit negotiations got under way this week to great fanfare — and letters. theresa may wrote to the eu to trigger article 50, the eu in turn published draft guidelines on its negotiation strategy, but as expected there was no more detail on the content of a deal, and this morning sir michael fallon would not be drawn on whether the uk would have full control

over its immigration system by 2020. well, you're speculating about the course of the negotiations, which haven't even started yet. well, you can rule it out. we've made clear that we are not expecting to take advantage of the four great freedoms, including the freedom of movement of people, because we're not going to be members of the european union. i'm talking about transitionally, now you can't give me any timetable. we can't give a timetable on negotiations that haven't even started. the uk is set to leave the eu by the end of march 2019, just over a year later the country will have a general election. the government will want to avoid setting time limits on such a thorny issue as immigration. but today, a group of cross—party mps wrote an open letter calling on the rights of eu staff in the nhs to be protected. because we have 140,000 eu nationals working in our nhs and social care sector, caring for our sick and elderly, we think they should be given an nhs guarantee that they will be able to carry on working in the nhs.

they need that certainty and they need those rights. theresa may has made it clear she wants the rights of eu nationals in the uk, and uk nationals living in the eu, to be a priority in these negotiations. immigration was a key issue in the referendum campaign, it will be again. elli price, bbc news. the triggering of article 50 has also raised questions about the status of gibraltar. our political correspondent ellie pricejoined me a little earlier to explain more. theresa may wrote a letter triggering article 50 on wednesday in which she didn't mention the issue of gibraltar. that might not have been an issue had the eu not replied with its draft guidelines in which it said the spanish government would have a veto over any future trade agreements that britain had with the eu specifically relating to gibraltar. what this has set in motion is a lot

of newspaper headlines and lots of people talking about it. today we see downing street trying to dampen it down, we understand theresa may has spoken to the chief minister of gibraltar on the phone to reiterate her position that the uk remains steadfastly committed to gibraltar, its people and its economy. this morning we heard from the defence secretary, michael fallon, who was also reiterating that gibraltar is a key priority for britain in these negotiations. the letter was about notification, the formal notification we are leaving, and about the process of negotiation, how we want the talks to be handled, but the letter referred to the brexit white paper and gibraltar is firmly in the white paper. you will find eight separate references to gibraltar in the white paper, and all the different issues we have got to deal with are set out in that white paper, whether it's the position of the city of london or fisheries policy, gibraltar and everything else. the key issue being gibraltar

will not be used as a bargaining chip, the government saying these negotiations haven't started yet so let's calm down. then we had the former conservative leader michael howard seemingly ramping up the rhetoric again. i think there's no question whatever that our government will stand by gibraltar. 35 years ago this week, another woman prime minister sent a task force halfway across the world to defend the freedom of another small group of british people against another spanish—speaking country, and i'm absolutely certain that our current prime minister will show the same resolve in standing by the people of gibraltar. is mr howard there really talking about going to war for gibraltar? that's how some of the critics have interpreted it. we have had tim farron, the leader of the lib dems, say it is unbelievable there are conservatives already discussing potential wars

with our european neighbours. i suspect not, but it is strong rhetoric from the former conservative leader, and i suspect also these are comments which will not be particularly welcomed by downing street today. the writer, broadcaster and civil liberties campaigner darcus howe has died at the age of 7a. his was most well known for organising the 20,000 strong black people's march in 1981 claiming neglect and insufficient policing of the investigation into the new cross fire which killed 13 black teenagers. iamjoined by i am joined by representatives from the society of black lawyers. he made a significant contribution

to the black community, especially the caribbean community, in the uk over the years. he had a fantastic and very heavy, resonant trinidad accent, and he waxed lyrical on a whole host of subjects at a time when it was unfashionable to talk about racism, claudio was in britain. how closely did you work with him? i worked with him over the yea rs with him? i worked with him over the years from ten to ten, appeared on his television shows on channel 4 and others. sometimes we were at odds. i remember one particular meeting in brixton where he called foran meeting in brixton where he called for an uprising of young people in brixton, and he received some criticism from the audience saying that he was not going to be arrested but it was an impact that would fall heavily on our young people. but generally speaking he was a very

popular advocate. he came with a new, academic and often challenging approach to the british establishment and was a key figure at the time that you mentioned, and then played a leading role in transforming the documentary agenda about our communities, with fantastic discussion programmes covering the breadth of the country, doing reports from the caribbean and africa, to my recollection, at a time when there were not very many black journalists time when there were not very many blackjournalists performing that role, given that opportunity. what you think are the highlights of his career? i think really the television series that he produced through channel 4. and the discussions he held on a variety of subjects, from deaths in custody to the growth of a black middle class.

he also commented on the anti—apartheid movement. there were anti—apartheid movement. there were a number of different highlights. our thoughts go out to his friends and family at this time. what challenges did you face when he first came from trinidad, to study law to begin with. what sort of environment did he find himself in? any person of colour trying to study law at the time, in the 1960s or 19705, law at the time, in the 1960s or 1970s, his colleagues, one of them was the former kenyan lawyer, he could not get training at the time, they were rejected by the establishment —— ghanaian. you are regarded as more likely to be an defendant and advocate when you

walked into the court. he was one of the pioneers, he did not return to the pioneers, he did not return to the caribbean but stayed and fought the caribbean but stayed and fought the struggle from the united kingdom. thank you very much for your time. remembering darcus howe, who has died at the age of 7a. police in pakistan say that at least 70 people have killed in punjab. our islamabad correspondent has more. 20 bodies were brought to hospital last night after four people managed

to escape. the killer is thought to be this man, the custodian of the shrine, arrested by police along with two alleged accomplices. translation: the three accused to under arrest indicted the disciples to the shrine. as they kept arriving, they were torturing murdering them. in islamabad, mourners gathered to pay their respects at the home of one of the victims. the shrine where this attack happened was dedicated to someone of whom the suspected killer was a follower. what was he thinking, what was in his heart? we do not know. there had been reports that evil cheese at this shrine would be regularly beaten either man that they followed —— that devotees at

this shrine. dramatic video posted on social media showed a fire exploding seconds after the fuse was ignited, sending debris into the crowd. police said that a wooden effigy had been dosed with petrol before it was lit. so much sport today, let us get a full round—up from the bbc sport centre. we have been very busy. thank you. there was one win for oxbridge and one for cambridge. cambridge won the women's race after a terrible start for oxford, but then they were out of contention before it even began. but oxford's men had no problem, as

they led from start to finish. our correspondent is on the banks of the river thames. iam here river thames. i am here at the start of the race on putney embankment. it is much quieter now. the men's race came to an end about 20 minutes ago, it was oxford who were victorious. it was a battle at the start but then oxford took control using their experience, their power. they were the favourites going into the race. they took back the title the wasp last year and getting even closer to the overall standings but cambridge have 82 wins and no oxford have 81. the women's race was a little disappointing. it was almost over before it began when the oxford crew caught the war in the first stroke that the took. they lost all of their momentum and rhythm and

cambridge fully categorised on that. the poor number four just cambridge fully categorised on that. the poor number fourjust could not get her oar out from the bottom. it is one apiece. oxford won the men's race, cambridge won the women's race. it had been a beautiful day here. they were worried that the race would not be able to take place at all, but it did and it has been a wonderful day. celtic clinched the six consecutive scottish premiership title this afternoon after beating heart of midlothian 5—0. brendan rodgers's side i know —— are no clear of aberdeen by more than 20 points at the top of the table.

a 5-0 the top of the table. a5—0 win the top of the table. a 5—0 win wrapped it up in some style, pretty much indicative of the season as style, pretty much indicative of the season as a whole. they have been ruthless, efficient, hungry, and brendan rodgers. there will be talk about a lack of competition in scottish food, but take nothing away from this celtic side under the former liverpool manager. a massive gap between them and aberdeen in second place, and they have finished this with eight games to spear. in terms of the ambitions between now and the end of the season, they have two particular ambitions, the scottish cup would complete the domestic treble and they have the chance to go on unbeaten and become invincible. the way that they are playing today and this season, you would not bet against it. there were two premier league games today. swansea and middlesbrough ended goalless. that does not help either side as they fight

relegation. there was a huge opportunity for the top four at the emirates, but it finished 2—2. arsene wenger says that he wants to stay in management next season, even though he has yet to reveal whether it will be with arsenal. for old people, retirement is dying, he declared before the match with manchester city. well the frenchman is very much alive, his side were lacking inch wide vivre. for a while, manchester city looked like they might get another tier. theo walcott worked ha rd they might get another tier. theo walcott worked hard to draw them level. u nfortu nately for walcott worked hard to draw them level. unfortunately for him it took just two minutes and 11 seconds for his efforts to be undone. sergio aguero found himself on the sidelines at city until gabriele ——

gabriele who is this was injured. arsenal were brought back into the game early in the second—half. but a bit like arsene wenger‘s future, there was no way of knowing which way this would go. so it was perhaps unsurprising that it ended in stalemate, leaving arsenal fans hoping for a more definitive result on dear manager's future sooner rather than later. saracens will be the only british side in the semifinals of rugby union's champions cup after they beat glasgow 38—15. they have on unbeaten record year in the champions cup and that continued today as they ran in four tries. they will now travel to dublin to play munster in the last four. that is all of the sport. next up it is the weather. a decent start the weekend for the

vast majority. we did see some thicker cloud across eastern areas, but for many it was a lovely day. clear skies overnight, last night was similar, it will turn chilly. some patchy rain in the western isles by the end of the night. temperatures will remain about eight 01’ temperatures will remain about eight or nine celsius. in the country it will be lower than that, at its chilly first thing but bright start for much of england and wales. workload and breeze and patchy rain for northern ireland and western scotland. for the bulk of england and wales it is a decent day. not quite so warm and choose day, quite green the south—east with early patchy rain, but that does not last too long. places will be dry and bright. a race against time in colombia as rescuers search for survivors of devastating mudslides. at least 200 people have been killed

after a torrent of mud and debris engulfed the town of mocoa in the amazon basin. the prime minister tries to reassure the people of gibraltar, saying britain will work with the territory to get the best possible brexit outcome. a teenage asylum seeker remains seriously ill in hospital after being attacked by a group of people at a bus stop in south london. and celtic celebrate a sixth successive scottish league title. good evening. rescue teams in colombia are continuing to search through tonnes of mud and debris for anyone who survived devastating mudslides in the amazon basin.

at least 200 people have been killed but with hundreds of others injured or missing, the colombian president says its impossible to know what the eventual death toll will be. the torrent of mud engulfed the town of mocoa, where rescue efforts are being hampered by bad weather. richard lister reports. this is a place of mud and misery. houses and cars, trees and people we re houses and cars, trees and people were swept away. whole families died here. the painstaking search for survivors is continuing. rescue workers moving quietly through flattens neighbourhoods hoping for a sense of life in the wreckage. nothing here. with every hour that passes, hopes of finding more people

live diminish. within hours of the deluge, message boards went up listing the dead and the missing, many of those unaccounted for our children. —— our children. we are searching for a baby, she says, a little baby, we cannot find him anywhere. this man has lost his daughter. i hope somebody has her, he says. she is cold louisa. closest to the river, people are trying to retrieve what they can of their lives. the shock of this disaster is still sinking in. the rains that caused this flood were unusually heavy, but deforestation upstream played a part as well. this tone of 40,000 people is still without power 01’ 40,000 people is still without power or freshwater. the 40,000 people is still without power orfreshwater. the homeless need

housing, infrastructure needs to be restarted and the debris cleared. deepin restarted and the debris cleared. deep in the amazon basin, it was ha rd to deep in the amazon basin, it was hard to reach before. now with roads and bridges washed away, the challenges even greater. the prime minister has told the people of gibraltar that the uk would never allow it to slip from british control against their will. in a telephone call aimed at reassuring gibraltar about its future after brexit, theresa may said britain was steadfast in its commitment. here's our political correspondent iain watson. legend has it when the apes leave gibraltar, the british will not be far behind. they are still here. but the residents who want to remain british are worried that the spanish government could soon have more say over their lives. the eu have said that after brexit london will have to top directly to spain about the territory's future.

another woman prime minister sent a task force halfway across the world to protect another small group of british people against another spanish—speaking country. but do not panic. four days after triggering the brexit process there is no seediest talk of conflict within nato ally. spain seems more interested in talking about trade than seizing territory. the bbc has been told that gibraltar did ask downing street specifically to mention its interests in the letter sent to the european union triggering the brexit process. we know that that did not happen, but today theresa may got on the telephone to gibraltar‘s more senior politician, and pledged her steadfast support, not just for

there it's our country but for the economy. and the minister of gibraltar seemed reassured. when the time comes, we will be making tactical negotiations and interest of the people of gibraltar and in pursuit of wishes. but there could still be an economic risk for gibraltar. how will the deal affect the gibraltar economy? the economy could be strangled as the negotiations go wrong. this isjust be strangled as the negotiations go wrong. this is just the be strangled as the negotiations go wrong. this isjust the start of be strangled as the negotiations go wrong. this is just the start of the process of leaving the european union. downing street has
