hello and welcome to world news today. a couple in california have been sentenced to life in prison for starving their 13 children. david and louise turpin pleaded guilty to m counts of cruelty, torture and false imprisonment, in february. they were arrested last year after their 17—year—old daughter managed to escape the family home and raise the alarm. before the sentencing some of the turpin‘s children read out statements in court, which reduced their parents to tears. sophie long was there when thejudge gave his ruling. both david and louise turpin were sitting in the courtroom behind me and they were both sat there crying as if to let their children read written statements to a packed courtroom. the first, a very frail young woman visibly upset, walked past her parents to the podium and she said that my parents took our life from us, but we had taken aback. she said i am a fighter and i am strong. after that, when of their sons

made his way to the podium and he read a statement on behalf of of his sister and then in his own words, he said that it's hard to put into words what their parents put them through, but that is the past and this is now. he said he still has nightmares about what happened, namely his siblings being changed to their beds. but he said he had learned so much since january when they were freed. he said he learned to ride a bike, which he enjoys and he learned to swim as well. another one of their children said she loved her parents very much and believes they did everything that they did to protect them. after they heard from dick chilton, luis turpin and her —— children. seat and said she was sorry for everything they had done and they loved their children more than they could ever know. the judge told the parents he sentenced them, that the only thing they had done right was to plead guilty to those 1a counts so that the children were spared reliving the trauma they separated over many years. —— suffered. and as you correctly say, the outside world was only alerted to the horrendous abuse

at these children suffered in january of last year when one of their daughters, 17 at the time, escaped through a window and she used a deactivated southbound to call the emergency services. —— cell phone. in the 911 call, you can hear her tell the operator that we are a family at 15, 13 children. our parents at dss. she said that two of my little sisters are chained to the beds right now. she said the still filthy sometimes she couldn't breathe and she did not know what medication was. now when the police arrived to the property, they found 12 of the children where it severely malnourished. now, some of the siblings were in their late 20s, but prosecutors said they looked like young teenage children because they had been starved for seven years. so many years. now both parents pleaded guilty to 1a counts, including adult abuse, child endangerment, torture, and 90 counts of false imprisonment. it's likely they will spend most of the rest of their lives in prison. sophie, that'sjust a staggering list of details. and very distressing, some of them, the numbers involved here the number of children is so large,

but i be any questions now about how this was allowed to happen and did the authorities need to answer any questions? we are expecting to hear from the authorities, one of them has been making a speech just outside the courthouse now, but that sentencing hearing has just come to a close. but of course there are many questions being asked of the authorities and the local community. this all happened in a town called paris, halfway between san diego and los angeles, a sleepy suburban town. and this abuse, the counts they admitted to took place between 2010 and last year, years these children were starved and found to be severely malnourished when they were rescued atjust over a year ago. so i think community, and authorities as well are all asking themselves, how possibly this level of abuse to so many children, 12 and 13, aged between 2—29 suffered this abuse. many questions being asked now.

sophie in california, going to washington now. robert mueller‘s report into russian interference in the us 2016 presidential election seems to have created even more questions and congress is determined to get answers. the democrats who control key house committees are using their powers to try and receive a full unredacted copy of the special prosecutor's findings. but as laura trevelyan reports, this legal and political battle could stretch on for quite a while. less than 2a hours after the attorney general released a redacted version of the mueller report, congress stepped in. thejudiciary committee issued a subpoena for the full report, saying lawmakers should not be kept in the dark. and they want it by may one. we need the whole report. we need the whole report, including underlying documents unredacted as has been the case and every previous situation similar to this, has congress got it all. the 4118 page report contains 90 redacted sections relating to

intelligence material and ongoing court cases. but it's the public bits of the report which had infuriated the president. he is angry with former white house officials who told robert mueller how he tried to thwart the investigation. this morning, he tweeted... the muller report finds no evidence of criminal conspiracy between the trump campaign in russia. but does not exonerate the president on obstruction of justice. the white house has said that he is in the clear. there was no collusion with russia and it should be a day that every american can celebrate and not be sorrowful like we have seen the last 48 hours from the democrats that are actually side the president did not work as a foreign agent. the president wants to focus on the 2020 election and what he hopes will be a second term, but with subpoenas

flying and some democrats under pressure from their base to impeach him, the saga of the mueller report is far from over. let's take a look at some of the other stories making the news... ukrainian president petro poroshenko squared off against comic and frontrunner volodymyr zelensky, in a theatrical televised presidential debate held in the country's olympic stadium. the two men traded barbs in front of thousands ahead of sunday's election. zelensky, who has no political experience, vowed to dismantle ukraine's political system. 13 people have been killed after a church wall collapsed in south africa. the accident, in kwazulu—natal province, followed heavy rains. one of the victims is reported to be just 11—years—old. thousands of people in peru have turned out for the funeral of the former president, alan garcia. the politician shot himself after the police tried to arrest him on bribery charges. the peruvian government offered the former

president a state funeral, but his family declined. a journalist has been shot dead in londonderry in northern ireland. 29 year old lyra mckee was struck by a bullet as she was observing an outbreak of violence in the creggan district on thursday night. a vigil for her has been attended by politicians on both sides of the community. her partner sara canning has paid tribute to her as a tireless advocate and activist, and described her death as senseless. police have started a murder inquiry and have blamed dissident republicans for her death. here's our ireland correspondent emma va rdy. shots ring out, a frightening throwback as violence erupts in derry. here, you see a gunman firing at police lines. then, they appear to try to remove the evidence. more than 50 petrol bombs were thrown, say police, and officers were shot at up

to ten times. journalist lyra mckee was hit as she stood beside an armoured police vehicle. a reporter nearby tried to help. i could see a land rover and there was a young woman lying on the ground beside the land rover, unconscious, and her friends were beside her. they hadn't realised what had happened. someone turned around and saw her on the ground and theyjust started screaming. it's a sound i'll never forget. described as a rising star, lyra mckee was a gay rights activist and freelance journalist. within the lgbt community we have a saying that we tell people. we tell them "it gets better". and what i realised that day is it gets better for some of us. it gets better for those of us who live long enough to see it get better. just after 11 o'clock, lyra mckee was taken to hospital in a police vehicle, but died of her wound. officers are treating her death as a terrorist incident and say

a murder inquiry has started. this morning, there was dismay that tensions continue to resurface. this city already harbours many memories from northern ireland's bloody past. it's terrible. i felt ashamed to be a derry man. those sort of things should be long gone, should not be happening now. and we need people like lyra i'm sorry. i couldn't believe it. itjust feels to me like we've gone ten steps back again, you know? so, just that type of violence in this town and the loss of a young life... it's very sad and i'm very sad because this is a lovely town. police believe the violence was orchestrated by the group known as the new ira. police say dissident republicans have been planning to attack officers over the easter weekend. yesterday, they carried out raids here on derry‘s creggan estate, looking for firearms.

the response was the violence which led to lyra mckee‘s death. this is an horrendous act, it's unnecessary, it's uncalled for, it's totally unjustified. but not only is it the murder of a young woman, it's an attack, again, upon the people of this city. hundreds lined the streets as political leaders from all the main parties and both sides of the political divide came together in a show of unity. we are political leaders, religious leaders, civic society and we all stand shoulder to shoulder to say we do not want to see this, we're not going backwards. we all have to stand against theirs. this is an attack on democracy, it's an attack on everybody that standing here today. lyra mckee‘s partner publicly grieved. it's left me without the love of my life, the woman that i was planning to grow old with. we are all poorer for the loss of lyra. despite the gains derry has made, today there is a deep sense of loss. many hope to see a renewed stand

against those who threaten to take the city back to its violent past. stay with us on bbc world news, still to come... the troubling legacy of the columbine high school shooting, 20 years on. sta rs & stars & stripes at half mast outside columbine high school, the school is sealed up, bodies of the dead still inside a. i never thought they would go through with it. when at the most successful singer—songwriter it's about time, american pop star prince has died at the age of 57. he was a great

musician and a genius stoplight millions of americans, that gap at richard nixon in a new york hospital has meant conflicting emotions national debt morning, sitting uneasily with the abiding memories of the shame of watergate stoplight and lift off, discovery with the hubble space telescope, our window oi'i hubble space telescope, our window on the universe. this is bbc world news today. the latest headlines... an american couple who tortured 13 children in a so called "house of horrors" are sentenced to life in prison. donald trump says it's game over, but democrats in congress issue a subpoena to see the full mueller report on russian interference in the 2016 election. climate change activists across europe have stepped up their protests against what they say is government

inaction against global warming. simultaneous protests took place in several european capitals. in paris, demonstrators cordoned off corporate headquarters with police—style tape. brandishing slogans they demanded action from president macron. in rome the swedish teenage activist greta thunberg addressed a packed rally. she said adults had given "false hope" to the young. and in london the oscar—winning actor emma thompson joined a mass protest in a show of solidarity. hundreds of police officers closed in on protesters as demonstrations entered a fifth day. sangita myska reports. following five days of disruption, the police began the work of removing the pink boat, the rallying point for climate change protesters in the heart of the uk's busiest shopping district, oxford circus. earlier today, 1000 police officers had poured onto london's streets, drafted in to end the climate change protests that had brought parts

of the capital to a standstill. the home secretary says he expects the police to use the full force of the law to end that disruption. it's certainly different from the sort of protest we're used to and we are an organisation that learns and we will debrief this operation once it is finished and we will learn what works and what didn't work, so if groups choose to take this approach again in future, we will be better placed to deal with it more swiftly. at waterloo bridge, a stone's throw from parliament, it's a game of cat and mouse. campaigners are lifted and removed by officers, some to return hours later, to do the same again. in five days, nearly 700 arrests and no end in sight. i've come out to do my bit and we're going to come back on monday and we'll be getting arrested again and may be locking on here again, doing what's necessary until the government is prepared

to speak with us. back at oxford street, retailers claim the disruption has cost them millions of pounds in lost trade, but campaigners say it is a price worth paying until their calls for radical government action to combat climate change are acted on. sangita myska, bbc news. it's emerged that president trump has spoken by phone to the libyan general, khalifa haftar, whose forces are attacking the country's capital, tripoli. the white house said that on monday, the two men discussed a shared vision for libya's transition to democracy. libya's un—backed prime minister has condemned the silence of the international community over general haftar‘s assault on tripoli. our international correspondent 0rla guerin has this report. in tripoli, once again it's time to bury the dead. mourners blame the military strongman

besieging the city, general khalifa haftar. critics say he wants to be a new gaddafi. libya's internationally recognised prime minister has held him off for two weeks with the help of a loose alliance of militias, but he's sounding worried. translation: this is a dangerous turning point, it's a confrontation to supporters of democracy and authoritarian rule. i'm astonished by the stand the international community. it's less a matter of taking a stand and more of dodging a bullet. these battles are raging around seven miles from the prime minister's office, but the international

community which was so hands—on during libya's revolution now has little to say. translation: there are divisions within the international community. some countries support the government. they recognise that there is an attack taking place. other countries don't have the courage to acknowledge that. we do not want this division to cause the international community to abandon libya as it did in 2011. what's the risk now that so—called islamic state can exploit this vacuum? they were driven from their stronghold at the end of 2017 but nobody imagined that they were gone completely. definitely, there is a fear that extremist elements, terrorist elements, may return. some cells are left and will certainly take advantage of the security vacuum. we fought and vanquished isis, now the

attack on tripoli has given these sales opportunity to reawaken. what about your personal safety? what do you think might happen to you if khalifa haftar manages to take over? i am living in the capital among 3 million libyans who are defending their city. what happens to them will happen to me, but we will fight to the death to defend our dream of establishing a democratic civilian state. the battle for tripoli may have an impact far beyond libya's shores. the prime minister says it's threatening the lives of 800,000 migrants here and could spark a flood to europe. saturday marks the 20th anniversary of the shooting at columbine high school. and for the final time, the city of littleton, colorado is holding events

to mark the tragedy. 13 people died, and more than twenty were injured, when two heavily armed students opened fire inside the school before killing themselves. that troubling legacy has had a lasting impact on the community. the bbc‘s nada tawfik travelled to colorado to see how the shooting shaped the lives of survivors and the nation. at this quiet memorial in littleton colorado, lies a lost piece of america's innocence. 13 crosses bear the names of the students and teacher who died on april 20, 1999. their lives taken suddenly went to high school seniors opened fire inside columbine high school. they had been laid to rest, while those who survived still carry the trauma of that day. a couple of us in the speech team started travelling to

speak to other students to tell our story. it took samantha more than a decade to seek help for ptsd and survivor's guilt. she managed to escape the shooting, but her close friend rachel did not. i could not even bring myself to personally give her things back to herfamily. because i did not know how to say... that i'm sorry that i survived. at the time of columbine, school shootings were rare. and so when the horrific news spread of what happened here, it was a genuine shock to the nation. now though, they are all too frequent. the current generation of students run drills on how to survive if their school is next and columbine isn't even among the ten deadliest mass shootings in the country. columbine, we are back! as principal, he let his school through a very public reading process. one that continues until today. i say with great pride... and every time there is another shooting,

he makes it his mission to call the principal at that school to lend his support. i know what they're going through and even though they are kids from parkland or newtown connecticut, they are all of our kids. i think we need to rise up as a nation and i really get credited to the kids from parkland last year when they basically said enough is enough. fight for your lives before someone else'sjob. in the immediate aftermath of the shooting in parkland florida that killed 17 people, the students became out outspoken activist, titling that killed 17 people, the nation. but the loss of to my classmates to a apparent suicide has left many survivors realising they need to look after themselves as well. on the positive side, we have gone to achieve national change so that it never really happens to anyone else or we had done our best to take steps in that direction, but from a personal perspective, we have really largely ignored the treatment at ourselves and we are suffering now at this point because we need

help and we are not getting it or giving it to ourselves. generations of americans had been permanently scarred by the travelling legacy at school shootings. 20 years on from columbine, survivors want to know how many more have to suffer before something changes. the international climbing community is in shock after the loss of three highly experienced mountain athletes. jess roskelley, david lama and hansjorg auer are all missing, presumed dead, after an avalanche swept down their route in canada's rocky mountains. the three men climbed mountains professionally and between them had conquered some of the toughest routes around the globe. earlier i spoke with their friend and fellow climber francis sanzaro. we don't have much more information to what happen conditions are pretty bad, but the fog and snow in that area particularly an avalanche standards are high to get rescue operation, as to where it their

bodies were found or at least one body was cited from the helicopter, so body was cited from the helicopter, so not much more information but however it's pretty much agreed upon that they did not survive the avalanche stoplight this is, you know, three people who really were experienced when they? absolutely, these were young strong, cutting—edge, they wanted to be in one very quick you know, having them all the sudden hearing about the debt there are no longer alive it just happened to like that, that's how it works in climbing, so it's very tragic for our community, we suffer a lot of depth as it is in the alpine community and to have three of our leading climbers though, we are absolutely heartbroken stoplight that must be a strange situation for you and your community to be in, what looking

from the outside, there are such high risks and this is something that everyone takes part, knows that telling and, it must be strange and very difficult for you guys to co nsta ntly very difficult for you guys to constantly have to receive news like this. it's a great point, all your long we have to report on the death of friends, it's a small community, but unfortunately the mortality rate is not in the favour of especially when you're in the elements, it extremely risky, there is a lot of things that are out of control for you, and it's very, very dangerous despite being taken many precautions that you can, it'sjust despite being taken many precautions that you can, it's just a despite being taken many precautions that you can, it'sjust a dangerous game we all they say we have to deal with it all the time stoplight that was francis. that's it for me, i'll be back with the headlines in a few minutes. don't forget you can get in touch with me and some

of my team on twitter, i'm @ lvaughanjones. you're watching bbc news. that evening. we had seen plenty of sunshine across the board through the day today, and temperature is hot responded. at times, fungi and turn hazy certainly not spoiling the feel of the day and all that sunshine how to get temperatures and extra boost of foreign nations have recorded the highest temperatures of the year so far, and more weight to come from most of us as we head into the weekend. an area of high pressure setting up a scandinavian settled story there, but we have a well—defined working its way in atlantic, it will make progress in introducing more cloud into price of northern ireland and western fringes in scotland overnight, cutting more breezy here but elsewhere, right winds and clear skies we see
