are battling to reach people trapped in wreckage, after a bridge over a motorway collapsed as a train was travelling on it. several carriages plunged onto cars below, at 10pm local time. at least 23 people are known to have died, and dozens have been injured. you may find some of the images in will grant's report upsetting. residents of mexico city are all too accustomed to this sort of scene, emergency services working through the night. emergency services working through the ni . ht. �* , emergency services working through the niuht. �* , ., w the night. attempting to reach in'ured the night. attempting to reach injured victims _ the night. attempting to reach injured victims trapped - the night. attempting to reach | injured victims trapped beneath the night. attempting to reach - injured victims trapped beneath the rubble but this was not another earthquake in the capital, rather it was an overpass in the city �*s busy subway system. it collapsed as a train travelled over it, bringing a tangle of wreckage, concrete and metal crashing onto the cars below. at that hour, the train with the most likely have been taking workers home after a late shift, a quiet night turning into tragedy in an

but supposedly not on line 12. yet many have said there were issues with its construction from the start. among them, local residents who complained about the endless expansion of the subway across the sprawling city. many of the tough questions ahead will be directed at the city �*s a former mayor, marcelo ebrard, now mexico �*s foreign minister maher chung can't line 12 and on twitter he said he would fully comply with the investigation into what happened. but such investigations will have to wait. now, the city is solely concerned with rescuing those trapped, attending to the injured, and the bereaved. will grant, bbc news. we can speak to will now at the scene. bring us up to date with everything that the emergency services are doing. figs that the emergency services are doinu. �* , , ., that the emergency services are doin., �*, that the emergency services are doini, �*, , that the emergency services are doin. a , , that the emergency services are doing. as you can see, they are busy behind me, —

most important part of the subway system, it can happen to other bridges and parts of the infrastructure. any questions for the authorities here. still many hours ahead, terrible and deeply upsetting wait for the families. thank you. foreign ministers from the world's leading economies are meeting in london for theirfirst face—to—face talks in more than two years. the g7 is expected to discuss new ways for the group to defend international rules. our diplomatic correspondent, james landale, is following the meeting. over the years, lancaster house has been the scene of some historic negotiations. this is a building where new nations have been formed and created but today, its playing host to a new form of what i think you could loosely call pandemic diplomacy. it is constrained, secure, but for the ministers who had spent months talking to one

another on video link, it is, at least, at last, face to face. diplomacy is slowly emerging from the virtual world. staff at lancaster house are remembering how to roll out the red carpet. visiting ministers are wearing masks and practising their awkward elbow bumps with the foreign secretary. but the crucial point is that they are here, in person, meeting face—to—face for the first time in more than two yea rs. much has been done to keep them safe. the delegations have been kept small, there are 35 litres of hand sanitiser here, and they will talk to each other through the transparent screens. and they have much to discuss, notjust the pandemic itself but also the state of the international order, as the foreign secretary and his us counterpart made clear ahead of the meeting. our societies, our economies have been shocked and shaken by coronavirus. at the same time, we are responding to a situation where our values are being challenged, the international

architecture is, at least in some respects, being weakened. the foreign secretary wants like—minded nations, largely liberal democracies, to form loose, agile alliances to better defend open societies from the threat of authoritarian states, including russia and china. and the americans are on the same page. what we are trying to do is to uphold the international rules—based order that our countries have invested so much in over so many decades, to the benefit, voting today is very much the start of a big diplomatic ear for the

united kingdom. there is the heads of government g7 taking place in cornwall injune and later in the yearin cornwall injune and later in the year in glasgow, the big united nations, 26 climate change summit, so this is the start of some main negotiations. decisive action as promised here today, that will be the test, probe the excitement about ministers meeting face—to—face, what exactly do they agree, notjust ministers meeting face—to—face, what exactly do they agree, not just to defend democracy but also deal with more immediate threats, for example, what did they agree on how to help poor countries get better access to covid vaccines? james, thank you. the official number of coronavirus cases in india has now topped 20 million. there's been no let up in the rate of infection, with more than 300,000 positive tests recorded for the 13th consecutive day. there are still reports of oxygen shortages in the capital, delhi, and the army has been asked to set up medical facilities to take the strain off hospitals. devina gupta sent this report.

desperate hope. that's what family members in this hospital in delhi are holding onto. it is a fight for life saving oxygen that some are losing fast. translation: | came - here because a man died. his death freed up a place and oxygen for my mother. translation: they put us in a shed when she needs i to go to intensive care. this oxygen bottle came from my house. we bought it ourselves. as india crosses over 20 million infected cases, many hospitals are choked like this. struggling with scarce resources. translation: the situation is really critical. _ there are no beds available. we are under pressure — the doctors, nurses, the orderlies. even the patients. we are all under pressure. for some hospitals, it's already too late. at least 26 lives have been lost in the last 72 hours in such hospitals that exhausted their oxygen supply.

just this morning, a tragedy was averted when a children's hospital in delhi only had two hours of oxygen left but the government so far denies any oxygen shortage. global aid is coming but the challenge is to ensure speedy distribution. so the indian government has roped in the army for better management. but with unabated chaos, many indians are providing help themselves. people like mohammed, an auto driver in bhopal, are pitching in with the little they have. translation: | made an auto - ambulance because i saw that people were carrying their sick mothers and fathers on their shoulders. sometimes, carrying an oxygen cylinder alongside. they can't afford ambulances. covid is not sparing sport either. the massively popular indian premier league cricket tournament has been postponed after at least four players tested positive.

it's a huge disappointment here for millions where cricket is almost a religion. however, the goal of saving lives has proved too important as india faces the darkest test for decades. devina gupta, bbc news. as covid restrictions across the uk continue to ease, mps are discussing whether vaccine certificates — which prove that someone has had a jab — would help life return to normal. obliging people to show they've been vaccinated before attending major events is controversial — but it's expected to be a feature of foreign travel this summer, with eu countries likely to require it. here's our health correspondent, anna collinson. as more than 3a million people in the uk will now know, when you get your coronavirus jab, you should receive a vaccination card. but it is likely that soon there will be an even easier way to know someone's vaccination status, or whether they have recently tested negative. while covid passports

or certificates may not be needed for essential shops or public transport, the government in england believes it could help crowds return to large events, like the trial of 21,000 fans due to attend the fa cup final here in wembley later this month. but for many, it is a controversial idea. i think the problems come once covid passports, whatever form they take, begin to be perceived as compulsory, once people begin to think that, in effect, this means that we've got to get vaccinated. and the danger with that is it can actually undermine people's willingness to be vaccinated. the professor is one of those giving evidence to mps and peers about the use of covid passports, both here and for international travel. the european union is holding its own talks about lifting restrictions on nonessential travel. suggested proposals include allowing british people who have had both jabs to visits by the summer, with the option of applying restrictions quickly if required.

a senior scientific adviser believes there should be no risk visiting countries like france or italy if infection rates fall to uk levels. the risk comes from going from a place like the uk with very low infection levels, and going to a place with much higher infection levels, and therefore having the risk of bringing infection back. if the two places are at comparable levels, and that is what the eu is saying, then there is no particular risk associated with travel. portugal is one country hoping to welcome back british tourists, but the government is urging people to be patient until they are satisfied it is safe and an official announcement is made. we don't want to reimport the virus, we have had a huge success in terms of our vaccination programme of bringing down the levels of covid here in the uk, so we need to be cautious. it is also a cautious message from the labour leader, who welcomes the prospect of foreign travel, but not if it would mean another lockdown. there is evidence across the world of the virus being out of control and increasing.

we've got to be very, very careful. we won't be safe here until, broadly, the virus is under control across the world. but do i want to see things return to normality? of course i do. as we enjoy new freedoms, transmission rates are expected to rise, although not to the levels we saw over the winter. the main concern is vaccines possibly not working as well against new variants. but, for now, the data is promising and the hope is for a much more normal summer. anna collinson, bbc news. people who live in care homes in england can now go on some trips outside — without needing to quarantine for a fortnight afterwards. new guidance allows walks or garden visits, but campaigners say the changes don't go far enough. our social affairs correspondent, alison holt, is with me. change in the guidance which takes effect today?— effect today? that's right, when someone goes _ effect today? that's right, when someone goes out _ effect today? that's right, when someone goes out of _ effect today? that's right, when someone goes out of a - effect today? that's right, when someone goes out of a care - effect today? that's right, when l someone goes out of a care home effect today? that's right, when - someone goes out of a care home it means they won't have to spend 14 daysin means they won't have to spend 14 days in the room in quarantine although i have to say, today being so raining and blowing, i suspect there will be many venturing out and

begin the most of that. they are allowed to go with a nominated visitor or a care worker, to a public space like a park, or to someone �*s garden. and i think it's worth remembering, the guidance was published on saturday so a lot of care homes won't have had time to take on board what it means. they have to do risk assessments, they have to do risk assessments, they have to do risk assessments, they have to make sure there are enough staff to support any visits out, so it's going to be something that is likely to ramp up as time goes by, and the weather gets better. but it is an important step forward. there's been increasing angerfrom families who feel as the rest of society opens up, the restrictions in care homes have gone on for too long and when you have for instance, someone with learning disabilities who is desperate to get out, spend time with theirfamily, who is desperate to get out, spend time with their family, i'm sure for many, it's felt like it's been rather a present for the last year. and families want to make sure that those limitations are not kept in

place for too long, there are some homes which have not followed guidance, they have still restricted people so today, a petition is being presented by campaigners to the prime minister and it's calling for each resident to have one name to relative or friend legally recognised as part of that essential care teams so whatever happens in the future, that person will still be able to have contact with the person they love. alison, thank the person they love. the time is 13:17. our top story this lunchtime. a desperate search for survivors in mexico city where at least 23 people are dead after a railway bridge collapses onto a busy road. and coming up, hull's year—long art project, inviting people to spend time reflecting in a glass—fronted box — hundreds of feet above the city. coming up on the bbc news channel, why world snooker champion mark selby could go on to challenge stephen hendry�*s record after winning his fourth title in front of a full house at the crucible theatre last night.

voters go to the polls across scotland, wales and england on thursday, in the biggest test of opinion outside the general election. more than 100 councils are being contested in england, and the members of the welsh and scottish parliaments will be elected. my colleague clive myrie is at holyrood for us. hello from a rather soggy edinburgh. actually, it's only northern ireland that won't be going to the polls on thursday. everywhere else in the uk, elections will include local councils, police and crime commissioners as well as the welsh senedd. the results across the country will show what impact keir starmer�*s leadership of labour is having. and here in scotland, elections to the holyrood parliament, that could see an snp overall

majority and possibly a mandate, the party says, for another independence referendum. our correspondent lewis goodall has this assessment of all thursday's votes. we've got a mammoth set of elections on may 6th. let's have a look at the different contests that are happening in different parts of the country. well, for a start, to look at england first, lots of elections taking place in england this time around, 143 councils, 5000 seats, two lots of elections because, of course, one set of those english council elections didn't take place last year as a result of the pandemic. all 129 members of the scottish parliament in holyrood up for election, all 60 members of the welsh senedd up for election. really, really important, those elections, given the huge powers that those devolved authorities, those parliaments have. all 39 police and crime commissioners up for election as well in england, important for policing in those areas. london assembly, 25 seats. the london mayoralty as well, lucky us, but notjust the london mayoralty but 13 directly elected mayors across england as well.

now, let's have a think about what victory might look like in the different places. obviously loads of attention going to be on the scottish parliament. snp currently have 61 seats, they need 65 seats to get a majority, that's what they really, really want. if they don't get it, they'll argue that if the scottish greens take them over the line for a pro—independence majority, that that would give them a reason, a mandate, to have another referendum. the other parties trying to stop them achieving that. in wales, labourjust trying to hang on, really. they've been in power since 1999, over 20 years, in wales, trying their best to keep as many of the 29 seats, almost a majority, that they currently have. conservatives, after a very good 2019 election performance, really trying to expand their numbers there as well. and if we think about england, what victory for keir starmer? his first test before the voters, of course, keir starmer, what that might look like. well, we could compare him to other leaders of the opposition in their first years, the increase in seats that they had. tony blair had a very good performance back in his first election in 1995, for example, 32%. william hague, 23.5%.

all of them have done reasonably well apart from jeremy corbyn, who went backwards, as you can see. where keir starmer fits on that list will be a reasonably good indication of how good a night he and labour have had but, of course, labour very nervous about the apparent vaccine polls bounce the conservatives apparently appear to be enjoying. our political correspondent nick eardley is with me. arguably, of all the elections this thursday, the race for seats for the holyrood parliamentjust over there could well be the most significant, particularly longer term? i could well be the most significant, particularly longer term?— particularly longer term? i think this is right- _ particularly longer term? i think this is right. this _ particularly longer term? i think this is right. this matters - particularly longer term? i think this is right. this matters not i particularly longer term? i think | this is right. this matters notjust to people in scotland but potentially to the whole uk. the big question being asked in the campaign trail is can be snp win an overall majority and control the scottish parliament on their own? if so, they will see that as a cast—iron mandate

to hold another referendum even if downing street still intends to say no to another referendum. nobody knows for sure if the snp will win that, it is very difficult to do under the hollywood system, some in the party are nervous about the results on thursday but even if they do not have that majority on their own, if you factor in the scottish greens, potentially alex salmond's alba party and the independence question will be a big part of the next parliament here. unionist parties want to stop the overall programme for to majority, there is a race for second between the conservatives who overtook labour last time and labour, who feel that campaign is going pretty well. there is the scottish liberal democrats too. at the election is notjust about independence, we saw during the pandemic the big health decisions, and that will be the

post—pandemic recovery on the minds of voters, but independence is a big issue closely watched notjust in edinburgh but from downing street. thank you, nick eardley, our political correspondent. for a round up of everything you need to know about the elections,?there's a guide on our website with much more information about who is standing where. that's at bbc.co.uk/news, or on the bbc news app. from here in edinburgh, back to you, jane. thank you, clive myrie at holyrood. the prosecution has opened its case against a west mercia police constable accused of the murder and manslaughter of the former aston villa footballer, dalian atkinson. pc benjamin monk has denied any wrongdoing leading to mr atkinson's death in 2016. our correspondent phil mackie is at birmingham crown court. yes, many people will remember dalian atkinson, a very well—known professional football with a long

and successful career, not least here in birmingham with aston villa. he retired in aylesham, and by the time of his death in 216 he had high blood pressure, heart disease and was on dialysis. it was on the eve of a hospital appointment that his behaviour became to become quite agitated and erratic, in the early hours of the morning he left his girlfriend and flatmate to drive to his father ernest's house in telford, appeared outside, shouting, ranting and bashing on the door. neighbours said they reported back to the police, who arrived soon after. pc benjamin monk and his colleague arrived. during the confrontation material atkinson, pc monk twice fired his taser unsuccessfully, the prosecution says that dalian atkinson died as a result of a third deployment of the

taser during which mr atkinson was incapacitated. the prosecution alleges that the police then acted beyond reasonable force in that he was kicked in the head by pc monk, they allege that that left an imprint on his forehead and that pc monk beat him with her tongue while he was lying on the ground. the trial is due to last another six weeks and both of those officers denied murder and assault. police have urged people living near aylesham in kent to remain cautious and vigilant following the murder of a community support officer a week ago. detectives say they haven't established a motive forjulia james' death, and have made no arrests. our correspondent simon jones is in aylesham. julia james was working from home last tuesday, she went out to walk her dog when she was attacked. she

had suffered head injuries which were very severe. hundreds of officers have been involved in the investigation since, but as yet there is no key suspect and no motive the police have been able to establish. no arrests have been made. the chief constable of kent police today visited the scene to get an update on what had been happening. he realises that this is a difficult time for kent police given they are now investigating the death of one of their own officers and he realised too that local people are feeling shocked and concerned. you've seen the previous interviews by mr richards, our assistant chief constable, so i repeat those messages, that is exactly what people should be doing. being vigilant, of course, thinking very carefully about their own safety and making sure that if you go out alone, telling people where you are, where you are going and suchlike. simonjones reporting for us from kent. bill and melinda gates have announced they are divorcing after 27 years of marriage. in a statement, the couple stressed

they would continue to work together on the charitable foundation that they set up to help tackle global poverty. peter bowes reports. one of the most famous and highest achieving couples in the world. wealthy beyond imagination, bill and melinda gates met at microsoft, but they are best known as a power couple for the work of their charitable foundation. the news that they are planning to separate came out of the blue. they both tweeted a statement: "after a great deal of thought and a lot of work on our relationship, we have made the decision to end our marriage." the couple will continue to work together at their foundation, but they say, "we no longer believe we can grow together as a couple in this next phase of our lives." the bill and melinda gates foundation has had a huge impact on the world of philanthropy, with billions spent fighting causes such as infectious diseases and encouraging vaccinations in children. they already had been developing

kind of the state philanthropic persona in a very public sense. bill with a focus on global health and climate change with a kind of technocratic approach. melinda with a focus on gender equity, a more community—centred approach. in a sense, i think their decoupling had already occurred. bill gates, who founded microsoft in 1975, is the world's fourth richest person, with a net worth of more than $100 billion. there is no word on any financial agreement between the couple. they have asked for space and privacy for theirfamily as they begin to navigate their new lives. peter bowes, bbc news, los angeles. hundreds of people in hull are taking part in a year—long art project which aims to give people time to reflect on their lives — without distractions. volunteers will be invited to spend an hour alone

in a glass—fronted box — perched hundreds of feet above the city. here's our arts correspondent, david sillito. it's been a really tough year for a lot of people. i'm really looking forward to it as being, really, a new beginning. we're in hull, or maybe more accurately, we're looking over hull. this is kate, one of the first visitors to a new arrival in the city. the hull vigil. wow. wow, it looks so blue. this is not how i expected it at all. i thought i was going to be terrified. she and more than 700 others will stand here for an hour at a time over the next 365 days,
