tonight at six — just two days on from the notre dame fire and thoughts are already turning to its restoration. a few moments ago, at the same time monday's fire started, church bells have been ringing across france. new images from inside the devastated cathedral. firefighters say they arrived at the scene within ten minutes of the first emergency call. translation: i went up into the towers. it was only when i got to the top that i saw how daunting it was. at some point, we heard an enormous noise, which must have been the spire falling down.

the french government has launched an international competition to find the best way to rebuild notre dame. also tonight. new plans to stop under—18s viewing porn. online sites could be blocked if they fail to check the age of those logging on. a third day of protests in london — activists say being arrested is part of their campaign to highlight climate change. i'm here because humanity's facing extinction and ecocide. i'm here as a peaceful protester, the government must take action. teenager amy el—keria took her own life in a psychaitric hospital. today, a private health care firm is hit with the biggest fine of its kind. new evidence about the link between bacon and bowel cancer — even sticking to nhs guidelines may put you at risk. and coming up on bbc news, it's advantage spurs going into tonight's champions league quarterfinal, but can manchester city turn things around at the etihad?

good evening and welcome to the bbc news at six. just a few minutes ago church bells rang out across france to mark the moment when notre dame cathedral caught fire. that was two days ago but already attention is turning to its restoration. the french government says there will be an international competition to find the best ideas for rebuilding the iconic building. fire fighters have denied suggestions that they were late to the scene — saying the first teams arrived within ten minutes of the first emergency calls. let'sjoin lucy williamson in paris. well after all the shock and leaf of the past two days attention is switching to what happened in that

cathedral on monday night. how the fire started, and how it was put out. today, fire crews have been speaking for the first time about the operation, and we have managed together the first few details of who was work on site that day, and what they were notre dame today is a cathedral divided by the fire. marks of tragedy surrounded by tranquillity. this video, given exclusively to the bbc by a member of the police, shows stained glass intact under a jagged hole where the roof used to be. polished pews lined up before piles of charred timber. that so much survived is perhaps extraordinary. the local mayor said there was a moment that night when fire crews told president macron they were not sure if notre dame could be saved. it is a very difficult site to attack. they couldn't get there, up there, with their scales. the normal scales are not large, they are not tall enough will stop

so they had to use other devices. they had to get into the building, they had to check the building was safe. they went in there and they did not have 100% certainty that they would be able to get down and get out. this is what firefighters faced that night. today, one of them spoke publicly for the first time. translation: i went up into the towers. it was only when i got to the top that i saw how daunting it was. it was extremely hot and we had to keep moving back, moving back. it was spreading very quickly. at some point, we heard an enormous noise which must have been the spire falling down. investigators have so far interviewed around 30 people. early reports suggest the fire began at the base of the cathedral‘s central spire, where a major restoration project was starting. the main contractor involved in the restoration work told us they were the only ones in the building on monday and had been putting up scaffolding, not doing anything involving heat or sparks.

they left at 5:50pm, he told us, turned off the electricity, and handed the keys to the caretaker. along the banks of the seine today, artists came to record a rare change in the city landscape. the prime minister has announced an international competition for architects to design the cathedral‘s new spire. lucy williamson, bbc news, paris. from july, people who try to view pornography online will have to verify that they are over eighteen years old. checks will include submitting id such as credit cards or passports. but as our media editor amol rajan reports, there could be ways round the new checks. like so many industries, porn has

shifted online in recent years, dragging with it concerns about who is using it. these changes are significant, but is there any prospect of them actually working? drew? hello mate, lovely to meet you. good to see you. drew wylie uses pornography. at 23, he belongs to a generation for whom porn has always been instantly accessible. everyone can basically now has access that from a very, very early age, so i think that the level of exposure is much more extreme. do you think that is dangerous? i mean, do you think a lot of young people are seeing stuff online they shouldn't have? i do. it's dangerous, because young people are learning about sex through pornography, which isn't — i don't feel that's how young people should be learning about sex. from july, users will have to prove their age using a variety of methods, such as with a credit card or passport, or with an age verification card bought over the counter. the aim is to block or find sites that don't comply, but this will prove tough in practise. a generation ago, if you wanted to buy some porn, you probably had

to go into a newsagent, reach up to the top shelf and encounter some pretty awkward questions. what the internet specialises in is removing that human friction and replacing scarcity with abundance. but as ever with the web, there needs to be a balance between the gains and freedoms and convenience and the risk of harming vulnerable people. that is what these reforms are aimed at. no wonder children's charities, who worry about the exposure of young minds, consider this new law an important step. what this piece of age verification works to do is to try and prevent the accidental exposure of young people to this content, because we are particularly worried about young people seeing this when they are not expecting to see it. amid the impulse to project children, many adults wanting to view legal pornography will be terrified about data leaks in the future. this academic at sunderland university has two main concerns. young people won't be put off looking at porn, they willjust go into different spaces to find it, so they'll be moving away from the spaces we have understood to be legal, into possibly more illegal spaces.

secondly, we have no idea what might happen to people's details, once it's entered into that database. there are grounds for thinking these changes may not work — at least immediately. younger internet users are often the most technically astute, able to circumvent blocks, and many sites in breach of the new rules will be based oversea, making them harder to reach and punish. amol rajan, bbc news. for a third day in a row, climate change activists from extinction rebellion have been protesting in central london. a goup gathered outside jeremy corbyn‘s home while others glued themselves to a carriage on the docklands light railway. so far, some 300 of them have been arrested. tom symonds is at oxford circus. this is normally one of the busiest bridges across the thames. extinction rebellion, a new, direct action protest group, hoped to take control of this

and other key london locations for up to two weeks. well, today, the police moved in. we have an emergency here and i don't think we are causing any harm. using powers designed to balance the right to protest with the need to reduce disruption. the police are taking this extremely slowly, not least to keep the temperature under control. but also because they are starting to run out of police cells. we are here because humanity is facing extinction. i'm here as a peaceful protester. the government must take action. their demands? the declaration of a climate emergency, radical cuts to carbon emissions. "we are sorry for the disruption", they say. the fact of the matter is, we have tried things that are less disruptive for over 30 years. we have been petitioning, marching, writing letters, nothing has been done. but they also brought a busy rail

line to a halt, the docklands light railway, using unusual tactics. cue angry commuters and this from london's mayor. i am worried about protesters that are targeting public transport because i am trying to encourage more and more londoners to use public transport because it is good for the environment. another target was oxford circus, used by 23 bus routes as well as black cabs. it is getting about, people can protest but for two weeks, i think it is too long. scotland yard appears intent on making sure that does not happen but then everyone sitting here has said they are prepared to be arrested. they believe we should all be more worried about this issue and they say their protests will continue. teams of fife officers going in at a group ata teams of fife officers going in at a group at a time and taking one person out each time, which is

taking an awful long time and they are being brought down to the police va ns are being brought down to the police vans here, it will take time and the protestors say they are intent on staying here, because that is how they will be noticed. the private mental health care group, the priory, has been fined 300,000 pounds following the death of a fourteen—year—old girl in its care. amy el—keria killed herself while a patient at a psychiatric hospital in east sussex in 2012. it's the largest fine of its kind imposed on a private health company. our health editor, hugh pym, reports. ijust remember her belly laugh, you know, how she loved her sisters. tania's happier memories of her daughter amy, but she won't ever forget the day amy died in the care of a private hospital. all i think about is when i met her in that hospital that night, and her laying there, pale, and i expected her to say "hi mum, i'm 0k", and she didn't. amy had a known history of suicide attempts. she was referred by the nhs to this mental health facility,

part of the priory group. but she was found dead in her room in november 2012. the company was taken to court, facing a health and safety prosecution, and pleaded guilty. passing sentence here at lewes crown court the judge, mrjustice dingemans, said the risks associated with patients like amy had not been considered, and that staff had not been suitably trained to deal with emergencies requiring resuscitation. he noted that priory health care had worked hard to improve service since amy's death. he said any penalty he imposed could never reflect the loss suffered by amy's family. amy's mother was highly critical of the company. public‘s eye have been finally been opened to what the priory stand for — profit over safety. today is an historic day in our fight for justice for amy. the priory group said it extended sincere apologies to the family, and would carry out a review of all services for young people.

it's not about money for me. it's about stopping these children and that these vulnerable people dying unnecessarily. amy's death was avoidable. in the words of her mother, amy was alone, far from home and her family when she died. she felt she owed it to her daughter to fight for justice. hugh pym, bbc news, lewes crown court. you can find details now to some cutting edge research that might open new ways to study brain disorders. scientists have managed to partially revive pig brains, four hours after they were removed from the body. the research at yale university could raise ethical questions about what it means to be alive and conscious. 0ur medical correspondent

fergus walsh explains. the brain is the most complex organ in the body. it was always assumed it gets irreversibly damaged within minutes of blood flow stopping. now, a remarkable study in the journal nature challenges that view. the scientists at yale school of medicine used brains from farm animals bred for pork. in all, 32 brains were collected from an abbatoir. four hours after death, the organs were placed in specially designed tanks and synthetic blood was pumped round at body temperature for six hours. remarkably, despite being dead for hours, cells within the brain started to function. there was activity in synapses. some brain circuits started to work. the brains began to use energy and oxygen, and blood flow was restored. this video shows some of the blood vessels of the partially revived organs. but there was no whole brain activity that might signal awareness.

what this indicates is individual neurones are viable, but are not capable of forming an organised global activity, this is not a functioning brain, but a cellarly active brain. when the brains were tested there was no global electrical activity on an eeg. researchers had been ready to anaesthetise and cool the organs if they had showed any science of consciousness. they didn't, so the brains were not alive, a crucial ethical point. it looks like this technology even if it could bring individual cells back to life, it can't bring the person back to life. it can't make the brain function as a whole, in the way that we think is important. what is ethically significant about brain death is that the person who was there, their personality, their thoughts, their memories, is gone forever. first, it gives scientists a new way of studying the brain,

where it's been damaged by diseases like alzheimer's or a stroke. in the long—term, it might allow them to revive parts of an injured brain. but it doesn't mean anyone declared brain dead can be restored to life. the idea of a brain kept alive and conscious outside the body remains science fiction. the time is 6.16pm. our top story this evening. church bells ring out across france at exactly the same time as monday's fire started at the notre dame. also tonight: iamat i am at the etihad, where manchester city's dream of an historic quadruple is on the line tonight. they face spurs in the second leg of the champions league quarterfinal and need to come back from 1—0 down.

coming up on sportsday on bbc news. liverpool take their 2—0 first leg lead to porto, butjurgen klopp insists his side will fight with all they have to reach the champions league semifinals. even small amounts of red and processed meat, such as an extra rasher of bacon a day, can increase the risk of bowel cancer. that's according to the latest study led by oxford university and funded by cancer research uk. the link between these meats and bowel cancer is not new, but the impact of the amount eaten is. nhs guidelines recommend no more than three rashers of bacon a day, but this research shows that even a small quantity of processed or red meat can increase the risk of bowel cancer. 0ur correspondent sima kotecha reports from birmingham. there's nothing quite like a bit of bacon and sausage... or is there?

medium breakfast, bacon well done... at this cafe, for some diners, it's a must, especially at breakfast. i enjoy it, i don't see anything wrong with it. i'll probably eat bacon and sausage four or five times a week. and it's the ideal start to the day. i'm not one for cereal, but i feel i'm quite healthy, active, at the age of 46. but now, this — further evidence suggests red and processed meat such as salami, bacon and hot dogs can be harmful if eaten regularly, even in small quantities. the six—year study showed that for those who ate the equivalent of one rasher of bacon per day, four out of 1,000 developed bowel cancer. and for those that ate three rashers of bacon per day, five out of 1,000 developed the same cancer. the advice is, the less you eat,

the lower the risk. this doesn't mean that you have to completely give up bacon or go vegetarian if you don't want to, but simple ways that you can cut down on the amount that you are eating can all make a big difference in your risk of bowel cancer. it is thought the chemicals associated with processing meat could increase the risk of cancer, and high—temperature cooking can also create carcinogenic chemicals. here, we have pork, beef and lamb, and there are suggestions that the protein in meat like this, which gives it its red colour, can damage the gut when it is broken down. but this butcher says there are always two sides to every story. good things in red meat, all the essential vitamins and minerals that you cannot get anywhere else, so a good, balanced diet. my grandfather used to swear by it and he lived a long and healthy life. processed and red meat is part

of many people's daily diet. whether today's findings influences what's on their plate in the days and weeks to come remains to be seen. but the advice from experts — don't eat too much and if you do, cut back. the court of appeal has rejected a challenge by the royal opera house, against a previous ruling in favour of a viola player, whose hearing was damaged during a rehearsal. christopher goldscheider was sitting in front of the brass section of the orchestra. our legal correspondent clive coleman is outside the royal opera house. what are the implications of this? george, they are massive. for years, there has been protection from noise regulations for workers but there has been a kind of myth that somehow they don't apply in live music and entertainment venues. this ruling blows away the myth and puts venues like this on the same footing as

perhaps a factory floor. it ensures that employers, whether they are employing orchestra members or any other staff members have to take a reasonably practicable steps to make sure they are not damaged through noise so that means dynamic risk assessments, anticipating, as happened in this case, a spike in the noise levels. if they don't do that, they can get sued. i don't think this ruling means the music will be turned off but i think it means it will be played a lot more quietly at times. thank you very much. the former president of peru, alan garcia, has died in hospital of gunshot wounds. he had shot himself in the head shortly after police arrived at his home to arrest him in connection with a bribery investigation. he had always denied any wrongdoing. mr garcia, who was 69, was alleged to be implicated in a scandal involving a brazilian construction company. a man has been arrested following an alleged altercation between joey barton, the boss of fleetwood football club,

and barnsley head coach daniel stendel at the 0akwell ground last saturday. the man attended a police station on wednesday where he was arrested on suspicion of a racially aggravated public order offence and racially aggravated assault. he remains in custody for questioning. south yorkshire police say inquiries are ongoing. dozens of academics at uk universities have told bbc news they've been "harassed" out of theirjobs and signed to stop allegations of bullying, discrimination or sexual figures obtained by the bbc show a total of £87 million has been paid out as part of the deals. victims say they are being silenced. rianna croxford reports. how do you solve a problem you can't see? nondisclosure agreements were designed to protect business secrets, but now, the bbc has found they're being misused by universities, keeping a lid on allegations of

bullying, discrimination and sexual misconduct. and this academic has broken her nda. she signed one during ongoing grievances relating to her disabilities, teaching and research role, particularly following her cancer diagnosis, and she felt pressure to sign. i had no choice, absolutely no choice, because without the money, we couldn't have paid our mortgage, we couldn't have put... i mean, mine was the sole income in the family, there was nothing we could do. the university of liverpool said it refutes these allegations in the strongest possible terms. since the bbc broke the story this morning, more than 50 people have come forward with allegations of bullying, gender and disability discrimination, and dozens of them are men.

one man said he was "reduced to a suicidal mess" after being bullied, and signing an nda ended his career. others said whole groups of staff had been gagged for trying to whistle—blow on malpractice. when you speak out, you don't just speak out, you basically destroy your career. emma chapman thinks she has a solution. she refused to sign an nda after claiming she was sexually harassed by a man at university college london. she fought for a confidentiality waiver, meaning she can speak out. but the pain is still there. it disturbs me that he could know my address, and i had nightmares of my house being set on fire, for example. emma took her case to a tribunal, but didn't win. as soon as it was over, she received several of these untraceable voicemails from an unknown caller in the middle of the night. so this goes on... police never found the caller. ucl is believed to be the only university to have taken action to end the use of ndas for misconduct cases.

it hopes other universities will follow suit. rianna croxford, bbc news. manchester city take on tottenham tonight in the decisive leg of the champions league quarterfinal. tottenham are currently 1—0 up. katie gornall is at the etihad stadium. this is a huge game for both clubs but there is an added incentive for city because they are chasing an historic quadruple trophies, something that has never been achieved before. if they are to keep the dream alive, they know they have to beat spurs tonight at the etihad. ahead of the game, city manager pep guardiola has called on notjust his players but the fans to prove to him that they want to be in the semifinal. you could say he's been deliberately provocative to try to create a more raucous atmosphere at the etihad as they look to overturn the etihad as they look to overturn the 1-0 the etihad as they look to overturn the 1—0 deficit from the first leg. the goal was scored by son heung—min of spurs, who will be a key player for spurs tonight, as they try to

cope with the absence of the injured harry kane. it is finely poised but livable are more comfortable in porto, 2—0 an aggregate, they are favourites to go through to the semifinals where they would face barcelona. time for a look at the weather. here's ben rich. yes, the rise in temperatures is under way, today we got up to 19 degrees, just above in places, fast forward to saturday and those temperatures are going to fly much further, up to 25 degrees in some places and that will put us well ahead of some places further south where you would expect it to be warmer. 19 in malaga and just ten in istanbul as we start the weekend. back to the here and now, it is dry out there and we have some clear spells with a bit of fog lapping on to the south coast. that will continue to drift westwards and we are likely to develop some cloud and fog across eastern parts of the uk as well. generally, a fine night, not especially cold. you may get a

pinch of frosted to the far north—east of scotland. tomorrow sta rts north—east of scotland. tomorrow starts off with areas of cloud and may be misty and murky in places but that should tend to burn away and clear and then we are looking at sunny skies. you will notice the strength of the breeze, a south—easterly, which will keep it cool along some north sea coasts. just 10 degrees in dundee for example at hartlepool. a similar story for the english channel coast, where the south—easterly wind is exposing, 12 in portland. coming on line, some real wants to be had, temperatures up a notch on today, 17-21 temperatures up a notch on today, 17—21 perhaps in that process continues on friday. good friday of course looks like blue skies from dawn until dusk in most places. even the north sea coasts not quite as chilly by this stage. the best of the temperatures, 21 in glasgow and birmingham. as we go through the easter weekend, high pressure will try to hold on. frontal systems are making attempts to push in from the north—west but they are not expected to make much progress so most of us

will stay dry and at least for a time, the temperatures up to 2a and maybe 25. that's all from the bbc news at six, so it's goodbye from me, and on bbc one, we nowjoin the bbc‘s news teams where you are.

hello, you're watching bbc news with me, shaun ley. the headline starc church bells have been ringing across france following the fire at notre—dame cathedral on monday. new images have emerged from inside the cathedral. firefighters say they arrived at the scene within ten minutes of the first emergency call.

i went into the talents, it was only when i got to the top that i saw how daunting it was. at some point we heard an enormous noise which must have been the spire falling down. people who watch pornography on the web will have to prove they are at least 18 years old from july this yearin least 18 years old from july this year in new measures helped to make the internet safer for children. a third day of protest in central london, activists say being arrested as part of their campaign to highlight climate change. the royal house loses its claim over hearing damage caused to a viola player at one of its rehearsals. ina player at one of its rehearsals. in a moment, time tojoin player at one of its rehearsals. in a moment, time to join the sportsday team, first a look at what is coming up on bbc news this evening. in beyond 100 days we will be looking ahead to the release of the redacted version of special counsel robert mueller‘s account
