our north america correspondent nomia iqbal sent this report from nashville — a warning, it contains some distressing footage. this is the moment when audrey hale prepares to kill. the 28—year—old turns up at the school in a car, shoots the glass to get inside, and then stalks the halls with a rifle. minutes later, police officers michael collazo and rex engelbert arrive. let's go! footage released by police shows when officer engelbert enters the school. after a room—to—room search of the ground floor... sounds like it's upstairs. ..they hear gunfire upstairs and head to intercept. as he rounds the corner, one of the officers spots the attacker and takes the shot. gunfire police say the assailant, audrey hale, carefully planned the attack, and that she was born a woman but recently identified

on social media as a man. her victims were nine—year—olds evelyn, hallie and william, and three staff members — cynthia peak, mike hill, and katherine koonce, the head teacher. police say audrey hale was a former student here at the school, had no criminal record, and that resentment may have been a motive. a friend of hale's has told the bbc tonight they communicated moments before the attack. i received an instagram dm from audrey, basically stating that i would see her on the news later on this evening, and that something tragic was about to happen. i was just speechless. like, i'mjust like... i'm sorry, like, i'm still trying to wrap my head around what we're going

through as a city. officers say hale had a manifesto and could have killed more people. we've determined that audrey bought seven firearms from five different local gun stores here legally. three of those weapons were used yesterday during the horrific tragedy. she was under care, a doctor's care for an emotional disorder. law enforcement knew nothing about the treatment she was receiving. it's caused president biden to renew his call to ban assault rifles — the type used in this shooting. he and lawmakers from both sides passed major gun safety legislation last year, but many republicans say a ban goes too far. the grief here is unimaginable, but it's all so familiar. mass shootings are now a regular occurrence

here in america. i've reported on a few, and what i tend to hear from people, and what i've have been hearing today, is they say, "we don't do politics, we do prayers." but guns are political. this is a deeply conservative state, and even the republican lawmaker who represents the district here published a christmas card last year which appeared to show him with his family, including young children, proudly holding assault rifles — the type of rifles that president biden has once again called to ban. but when you talk about a ban — when you mention that word, when you even talk about restrictions — people here don't want to hear it. they believe a ban or a restriction would be an infringement upon their constitutional right to bear arms. and what people here are much more focused on is praising the police officers for their quick reaction in shooting the assailant. hundreds of thousands of protesters in france have been staging another day

of strikes and rallies against the government's pension reforms, with some demonstrators clashing with riot police. people are angry after legislation to raise the retirement age in france from 62 to 64 was forced through by president emmanuel macron�*s government. our paris correspondent, lucy williamson, sent this report. the temperature rose as the sun went down. across france, fires burned like beliefs as bright as fever. young protesters with their rocks and bottles, disappearing in clouds of tear gas fired by riot police in bordeaux, in nantes, and in paris. it took minutes for this peaceful protest to turn violent. hidden amongst the main demonstration, masked protesters who are now taking on the police. running through the lines of police, the white and black helmets of the specialist units known as brav—m — rapid reaction teams, tasked with stamping out trouble.

a new target for protesters after growing allegations of abuse. a video emerged last week apparently showing brav—m officers hitting a protester in the face. and an audio recording appears to have captured threats, intimidation, and racist insults against a group of student protesters. "next time, you won't be going to the police station, you'll be going to the hospital," one officer is heard saying. salome was one of them. she's since filed a complaint and was back out protesting today. it is important that police can contain violence and protect people — but in that case, the violence was against us and they were not protecting us. we must be protected from them. that is really worrying to me. the protests across france today were, as usual, largely peaceful, and smaller than last week — but police say some mainstream protesters are joining agitators in attacking them.

after covid, after everything that happened in france, inflation and everything, people started to be really tense and that does not help to reduce the violence against the police because the police are representing the state, so in a way when you attack the police, you might feel you are protesting against the state. tonight, fires are burning across france as president macron struggles for a way out of this crisis, with political negotiations frozen and the streets on fire. lucy williamson, bbc news, paris. let's get some of the day's other news. the political party of the burmese nobel laureate aung san suu kyi has been dissolved by myanmar�*s military rulers. the national league for democracy had refused to re—register as a party under strict new rules introduced by the military. the terrorism threat level in northern ireland has been raised from substantial to severe, meaning an attack is considered highly likely. the british security service

mi5 say its assessment follows a rise in dissident republican activity, including a recent gun attack on a top police officer. this decision reverses a downgrade from last march, the first change in 12 years. the president of the international olympic committee has defended plans that would allow russian and belarusian athletes back into international competition as individual neutral athletes. thomas bach said allowing their participation "works" despite the ongoing war. the ioc had placed sanctions on russia and belarus following the russian invasion of ukraine in 2022. two women have been stabbed to death at a muslim religious centre in the portugese capital, lisbon. police shot the suspect in the leg and were then able to detain him. the attacker is believed to be of afghan origin, but the motive is unclear. both victims were portugese. one had taught the attacker english at the centre, and the other was a classmate.

at least 39 people have died in a fire at a migrant processing centre near the us—mexico border. mexico's president — andres manuel lopez obrador — says the migrants caused the fire, which broke out during a protest against their impending deportation. nickjohnson has the details — but a warning that you might find some of the images in this report distressing. this woman, from venezuela, frantic as her husband is taken to hospital. "i saw many people laying on the floor," she said. "i didn't know what to think. "they tell me nothing." dozens have been killed in the fire at this facility, which is used for processing migrants and sits just metres from mexico's border with the us. it's thought the fire broke out just after midnight, prompting the mobilisation of firefighters, ambulance and military personnel. the city ofjuarez is one of mexico's border towns, where many migrants remain stranded while they attempt to seek refuge

in the united states — the city of el paso, in texas, the other side of the border. the mexican president, andres manuel lopez obrador, claimed the fire started during a protest by migrants at the prospect of their deportation. translation: they put mats at the door of the shelter - and set them on fire as a protest and did not imagine that it would cause this terrible tragedy. the number of migrants from latin america heading to the mexican border towns has increased in recent weeks, as they anticipate the end of a trump era policy which gives the us government the power to quickly expel migrants trying to cross its border. as the number of migrants continues to increase, it's hoped further tragedies such as this can be avoided. nickjohnson, bbc news. joining me now is luicy pedroza in mexico city. she's a professor at the college of mexico. she's conducted research into the experience of migrants in the americas and other

parts of the world. thank you for taking the time to come onto the programme. what has been your reaction to the loss of life at this micro facility? the mexican president says it was started by migrants themselves.— themselves. well, first of all, thank you _ themselves. well, first of all, thank you very _ themselves. well, first of all, thank you very much - themselves. well, first of all, thank you very much for - themselves. well, first of all, thank you very much for this i thank you very much for this invitation to answer your question. i am appalled as a human being and very ashamed as a mexican citizen and i am enraged as an expert has observed migration policies developing over the last years. and especially i am enraged that the president has used the word shelter to describe a detention facility where people are kept, locked in a jail —like facility. this is not a shelter. we have seen the signs of these come in for some time.

you mention the signs of this coming for some time, were there any warning signs that this potentially could happen, especially considering the number of people who lost their lives? , ., ., , lives? yes, unfortunately there have been _ lives? yes, unfortunately there have been warning _ lives? yes, unfortunately there have been warning signs, - lives? yes, unfortunately there have been warning signs, just i have been warning signs, just in 2020 there was also a mutiny inside a detention facility of the same agency, but that was at the southern border of mexico. one person lost his life and that of course was very regrettable, but it pales in comparison to the loss of life that we have suffered from the night of yesterday. after today, 29 people are still in a critical condition, so we have known for years that the conditions inside these detention centres are inhuman, that there is a lack of hygiene, sanitation, that people are kept for hours on

end without food or water, that they are deprived of their personal belongings, their cell phone, no communication from the outside world, and to me that sounds more like jail and a shelter, in migrant shelter. so we can imagine five people were starting to rebel against this kind of detention and these appalling conditions. once more, what more is known about the people that were at this particular migrant processing centre? it is reported they were from different south american countries such as guatemala, honduras, el salvador. what more is known about them? most of these peeple — more is known about them? most of these people came _ more is known about them? most of these people came from - of these people came from central america, actually came from guatemala in the second largest group was from honduras. third was el salvador. there are also some nationals from venezuela. and even some nationals from

colombia. most of them if not everyone were men, because for families and women and children there are other detention facilities. this was one designated for men. thank you very much _ designated for men. thank you very much for— designated for men. thank you very much for your _ designated for men. thank you very much for your time. - designated for men. thank you j very much for your time. thank ou. stay with us on bbc news, still to come: a guided tour of london's new £5 billion super—sewer — aimed at cleaning up the river thames. the accident that happened here was of the sort that can, at worst, produce a meltdown. in this case, the precautions worked, but not quite well enough to prevent old fears about the safety features of these stations from resurfacing.

the republic of ireland has become the first country in the world to ban smoking in the workplace. from today, anyone lighting up in offices, businesses, pubs and restaurants will face a heavy fine. the president was on his way out of the washington hilton hotel, where he had been addressing a trade union conference. the small crowd outside included his assailant. it has become - a symbol of paris. 100 years ago, many parisians| wished it had never been built. the eiffel tower's birthday is- being marked by a re—enactment of the first ascent by gustave eiffel. j this is bbc news, the latest headlines: police in the us say the suspect involved in a mass shooting at a school in nashville had legally purchased seven guns. clashes have erupted in france between police and protesters angry with president macron's pension reform plans.

more action is planned for next month. president biden says he hopes that the israeli prime minister will abandon the judicial reform law that has sparked weeks of protests and a political crisis. benjamin netanyahu delayed the proposal on monday after large numbers of people took to the streets. speaking from the tarmac before boarding air force one, president biden said he hoped mr netanyahu would try to work out a genuine compromise. like many strong supporters, i'm very concerned. and i'm concerned that they get this straight. they cannot continue down this road. and i've sort of made that clear. hopefully, the prime minister will act in a way that he's going to try to work out some genuine compromise, but that remains to be seen. let's cross to our north america correspondent, peter bowes.

peter, we have heard some farmers from president biden, is american getting firmer on israel? it is american getting firmer on israel? . , , . , is american getting firmer on israel? ., , , ., , ., , israel? it appears to be the case, president _ israel? it appears to be the case, president biden - israel? it appears to be the case, president biden is . israel? it appears to be the i case, president biden is using stronger language. what's interesting about this is that there is somewhat confused. 2a hours ago, the beginning of the week, after benjamin netanyahu announced he was delaying those controversial plans to reform the judiciary, controversial plans to reform thejudiciary, the line controversial plans to reform the judiciary, the line from the judiciary, the line from the white house in washington was that there should be compromise on those proposals. now we have president biden still talking about compromise but also saying that mr netanyahu should walk away from those plans, that there should be abandoned altogether. so it's difficult to proceed at the moment in terms of where the moment in terms of where the president draws the line, does he think there is any credit in those, at least part of those reform plans, the basis for a compromise, or

should they be thrown out altogether? i think way it is significant that he is in this way criticising what mr netanyahu is or had been hoping to achieve. netanyahu is or had been hoping to achieve-— to achieve. has to be any reaction _ to achieve. has to be any reaction to _ to achieve. has to be any reaction to president - to achieve. has to be any - reaction to president biden's comments?— reaction to president biden's comments? ., , , comments? -- has there been. it's a while _ comments? -- has there been. it's a while since _ comments? -- has there been. it's a while since he _ comments? -- has there been. it's a while since he made - it's a while since he made those comments but i think what is interesting is howjewish groups here in the united states have been responding not just in the last 2a hours but over the several days that we have seen these protests intensifying in israel. these are pro—israeli government groups in the united states, that under normal circumstances would want to try to be speaking with a uniform voice, but there are differences emerging in terms of the message that they are sending. it's actually quite similar to the differences we are seeing in the messages coming out in the white house. we are seeing and hearing some criticism,

yes, what the protesters are doing but we are also seeing some praise of those protesters in terms of the stance they are taking. in terms of the stance they are takina. . ~ in terms of the stance they are takina. ., ~ i. ., taking. peter, thank you for that update. _ if approved, will ban the production and sale the italian government has introduced a draft law that, if approved, will ban the production and sale of synthetic foods — including artificial meat. the bill would ban the sale, production and importation of food "from cell cultures or tissues derived from animals". if the ban is approved by parliament, penalties for violators would include fines of up to $65,000. sophia joins me now. what is this ban about? this sophia joins me now. what is this ban about?— this ban about? as you mentioned, _ this ban about? as you mentioned, plant - this ban about? as you i mentioned, plant -based this ban about? as you - mentioned, plant -based meat, mentioned, plant —based meat, which is made using soya, this has been around for years, but this new legislation, or the plan for the legislation, is

banning the use of synthetic products that are made in laboratories. the way that works is that you take living cells from animals, you grow them in a laboratory, and you produce food that tastes like meat without having to actually slaughter any animals. this is seen as hugely, having huge potential because it's a way to produce food that tastes like meat, that looks like meat, but it doesn't involve the killing of any animals. that's why this new ban in italy has attracted quite a lot of criticism from animal rights groups, because they are saying that lab grown meat is more sustainable, it's a good option and it could be the future. a good option and it could be the future-— a good option and it could be the future. �* , .., . the future. are they concerned about... the future. are they concerned about- -- why _ the future. are they concerned about... why is _ the future. are they concerned about... why is the _ the future. are they concerned about... why is the talent - the future. are they concerned about... why is the talent and | about... why is the talent and introducing this ban? about. .. why is the talent and introducing this ban?- introducing this ban? they haven't identified - introducing this ban? they haven't identified any - introducing this ban? they. haven't identified any major concerns and some say this is a political move. the italian government is a right—wing nationalist government and they

have pledged to protect italian food, which of course in italy is seen as a national treasure, from technological advances that could be harmful. in this case they are seeing synthetic meat as a threat to the traditional link between agriculture and food production. and so, italy is seen by the italian government as being on the forefront of food safety and food quality, so they are very careful about what they are allowed in. now, synthetic food is not widely available yet, but there has been quite a lot of promising research into how to produce it in last year, the us deemed synthetic meat safe to eat. so is very possible that in the next couple of years, this could be available to buy in supermarkets, because it is more sustainable and environmentally friendly, could become quite popular. interesting stuff, thank you very much. for decades london's victorian—era sewers have

discharged raw sewage into the river thames after heavy rain. but that could be about to change, thanks to a vast tunnel that's been built underneath the river — seven metres wide and 25km long. our environment correspondent jonah fisher was given a rare opportunity to ride a bike along the tunnel before it fills up with sewage. just looking for history. looking for stories, really. lara is a mudlark, forever searching the brown banks of the river thames. ifound a complete iron age pot, a tudor shoe... but alongside the treasures are more familiar items that have been flushed away. condoms, tampax applicators, sanitary towels, wet wipes. we are spoiling it, you know? we are pouring our waste into it and just destroying it. but deep beneath the river, the clean—up plan is nearly ready to flow. a £5 billion tunnel, the largest and deepest the capital has ever seen.

the reason we are riding on bikes through this tunnel is because it'sjust so big — it's 15 miles long, all the way across london, under the river thames. and the idea behind it is, well, that it will collect the sewage and storm water that at the moment goes into the river, and take it downhill to east london where it can be processed properly. here we are at the victoria interception point, which is this connection tunnel here. we believe that we'll capture 95% of the volume of spills into the river, and that will all be because rather than going into the river it's coming through a tunnel like that into this tunnel. this will clean up the river quite significantly? absolutely. not far upstream, what we throw down the loo is actually changing the course of the river. after years of abuse, just maybe the tide has turned. jonah fisher, bbc news, on the

banks of the river thames. authorities in amsterdam have launched a new initiative to try and deter british holiday—makers from visiting, if they just want to party. two new warning videos have been programmed to pop up if people search online for things like "pub crawl amsterdam" or "cheap holiday amsterdam". the ads, targeted at young males would show the risks and consequences of anti—social behaviour and excessive drug and alcohol abuse, including fines, arrest, criminal records and health issues. the city has long been trying to curb rowdy behaviour, especially near the famed red light area, where sex workers operate. now then, it's been a while since we did a proper animal story to end the programme, so here goes. they may look small, but one day these dragon hatchlings will grow sharp teeth — and possibly tower over us humans, at nearly ten feet tall.

hello again. after the sunny weather most of us had on monday, tuesday's weather was, well, a little bit disappointing, wasn't it? it was cloudy, it was wet, and it was quite cool — but temperatures will be rising into wednesday. we had a lot of cloud around and outbreaks of rain. so quite a damp start to wednesday, i think, with a few mist and fog patches around the coast and hills

in the west, but temperatures starting off wednesday at around 10—11 celsius in places. now, for wednesday itself, we've got several weather fronts that will be pushing across the uk, each bringing episodes of rain. so, a cloudy and damp start to the day, then we get these bursts of fairly heavy rain working in from the southwest — some of the wettest weather through the morning across northern ireland and western scotland, then later in the day, wales and parts of southern england could get some really heavy rain, might even see some localised surface—water flooding. it's unsettled, but it is mild, temperatures up to around 15, maybe 16 celsius. those gusty southwesterly winds continue then through wednesday night, and into thursday, it's a slightly less damp day, i'd say. brighter skies, there'll be a bit more in the way of sunshine around, but it is a day of sunshine and showers. and come the afternoon, the showers are going to be quite widespread — some of them heavy, the greatest risk of seeing thunderstorms stretches from southwest england towards the home counties and east anglia. temperatures, though, could hit 16 or even 17 celsius, which would make it one of the warmest days of the year so far.

from thursday into friday, well, we get more rain. the rain will be widespread across england and wales, some of it'll be really heavy. across more northern areas into scotland, perhaps the far north of england, you're escaping with some drier and brighter weather here. a few spots of rain across eastern areas. those temperatures, though, won't be as high — 12—13 celsius, but those rainfall totals mounting up on the last day of the month. heading into april, well, it's unsettled still — "april showers" pretty much sums it up. expect a bit more rain this weekend.

this is bbc news, the headlines... police in the us city of nashville have said the suspect involved in a mass shooting at a school had legally purchased seven firearms. audrey hale, a 28—year—old former pupil, shot six people dead, including three children, before being killed by officers. paris police say 27 people have been arrested in the french capital during clashes between police and protesters angry with president macron's pension reform plans. there was further violence after the government forced through the legislation without a vote in the lower house of parliament. at least a0 people have died in a fire at a migrant processing centre on the mexico—us border. many of the victims are thought to have been central and south american nationals trying to reach the united states.

dozens of people were also injured in the incident.
