tonight at ten — police use water cannon in belfast during another night of violence in northern ireland. firework screeches. these are the scenes in west belfast this evening — where fireworks and more petrol bombs have been thrown, despite calls for calm. it comes after violent clashes last night between catholic and protestant communities at the so—called peace wall. the scale of the disorder last night was at a scale that we have not seen in recent years in belfast or further afield. more than 50 police officers have been injured in the past few days. also tonight: the health secretary insists the oxford—astrazeneca vaccine remains safe — with the risk of a blood clot the same as going on a long haulflight. the chancellor, rishi sunak, releases text messages he sent to david cameron after the former prime minister asked the government

to help a finance company he was involved with. the mother of a 19—year—old student found dead in essex says his disappearance wasn't taken seriously enough by police. if richard was a different colour, if he wasn't black, i know it's hard to say that, but the discrimination was quite obvious. and heading back to some sort of normal — why some are finding rolling back restrictions daunting after a year of lockdown. and coming up in the sport on the bbc news channel: the masters is underway at augusta, but it's been frustrating first round for rory mcilroy. he finished with a 4 over par 76. good evening. police in northern ireland have used water cannon tonight as more petrol bombs and fireworks were thrown on the seventh night of violence

on the streets of belfast. the renewed unrest comes despite a plea for calm from the british and irish prime ministers, who issued a joint statement this evening. police say the clashes between catholic and protestant communities last night were some of the worst violence they have seen in recent years. during an emergency session of the northern ireland assembly today, politicians on all sides lined up to condemn the attacks. our ireland correspondent emma vardy has the latest. on an already febrile situation, now more fuel on the fire. at one of belfast�*s peace lines last night the peace was broken. in the hands of teenagers, petrol bombs, thrown in both directions over the wall. each

night these gates are locked to keep the mainly catholic and protestant communities apart. now forced open, rammed by cars and battered closed by police, amidst a running battle. it is hard to control. when kids see one side doing it theyjoin in. who one side doing it they 'oin in. who eneeueesg it h one side doing it they 'oin in. who encourages it the _ one side doing it they join in. who encourages it the loyalist - encourages it the loyalist politicians, _ encourages it the loyalist politicians, because - encourages it the loyalist politicians, because they| encourages it the loyalist. politicians, because they got encourages it the loyalist - politicians, because they got brexit in and it is not working. it will take months to repair the damage to this community, if it is ever repaired. fies this community, if it is ever repaired-— this community, if it is ever reaired. �* , repaired. as the fighting continued, local priests — repaired. as the fighting continued, local priests tried _ repaired. as the fighting continued, local priests tried to _ repaired. as the fighting continued, local priests tried to warn _ repaired. as the fighting continued, local priests tried to warn young - local priests tried to warn young people of the danger, themselves in harm's way. the attacks which lasted over an hour have been interrupted by the arrival of a police land rovers who have pushed the crowd back from this side of the wall. earlier, on the other side of the

our medical editor fergus walsh reports. business as usual in north—east london. headlines about blood clots didn't put people off getting the astrazeneca vaccine. the thought of catching covid is more risky than having a blood clot. any medicine has a side effect so i wasn't unduly concerned. 79 rare blood clots have been identified out of 20 million doses of the astrazeneca vaccine. the link isn't proven but in future the under 30s will be offered a different vaccine. for nearly all age groups, the benefits of the oxford—astrazeneca vaccine far outweigh any potential harms. for people in their 60s, with the current low level of virus circulation, for every 100,000 vaccinated, ia icu admissions would be prevented. at the same time, there would be a 0.2 or one in

500,000 risk of a rare serious plot. 500,000 risk of a rare serious clot. for people in their 20s, it's a finejudgment. there, less than one icu admission would be prevented but there would be just over one serious blood clot per 100,000 immunised. if we look at a period of high virus transmission, such as january, there, among the over 60s, 127 icu admissions would be prevented and nearly seven in the over 20s. neil aster began suffering headaches and nausea a week after having the astrazeneca vaccine. he died of a blood clot on the brain on easter sunday. his sister, a pharmacist, says he was extraordinarily unlucky. despite what has happened to neil and the impact on ourfamily, i

still strongly believe that people should be going ahead and having the vaccine. if you have had one dose, go ahead and have your second. if you haven't had a dose yet, make sure you do. overall, we will save more lives by people having the vaccine than not. the government says there will be enough pfizer and moderna doses for 8.5 million 18 to 29—year—olds to be vaccinated. the message from ministers one of reassurance. we know the roll out's working, the safety system is working and we are on track to meet goal of offering to all adults by the end ofjuly, and the speed of the roll—out would be affected by these decisions. when you get the call, get the jab. scientists tracking the epidemic in england say vaccines are weakening the link between cases and deaths. there are now far fewer fatalities per infection, because so many of us are protected.

a reminder why all of this really matters. fergus walsh, bbc news. let's take a look at the latest government coronavirus figures. there were 3,030 new coronavirus infections recorded in the latest 24—hour period. on average the number of new cases reported per day in the last week is 2,865. across the uk, an average ofjust over 3,000 people are in hospital with coronavirus. 53 deaths have been reported, that's people who died within 28 days of a positive covid—i9 test. on average in the past week, 31 deaths were announced every day. the total number of deaths is now 126,980. as for vaccinations, in the last 2a hour period, 99,530 people have had theirfirst dose, taking the overall number of people who've had their first jab to 31.8 million.the number of

people who've had their second dose of the vaccine in the latest 2a hour period is 408,396. that takes the overall number of people who've had their second jab to more than six million people. now to the lobbying row surrounding the former prime minister david cameron and the finance company, greensill capital. in a highly unusual move, the chancellor rishi sunak has made public two text messages he sent to david cameron last year. mr cameron had tried unsuccessfully to ask for help for the finance company where he was working as an advisor. here's our deputy political editor vicki young. former prime ministers don't have much trouble finding work after they leave number ten and david cameron is no exception. he served out the two—year required lobbying ban that ministers must stick to when they leave office, then ended up working for financial firm greensill capital as a paid employee. this, like so many other lobbying controversies, is a story about who has access to power, how they use it, and how the powerful respond.

mr cameron's relationship with lex greensill goes back to 2012. according to this business card passed to the bbc, the australian banker worked for him as a senior unpaid adviser in downing street. 12 months ago, at the height of the covid lockdown, mr cameron tried to persuade the treasury to increase greensill capital's access to government backed loans. sources say he sent multiple text messages to the chancellor rishi sunak�*s private phone. these haven't been released, but today, two replies have. on april the third last year mr sunak thanked mr cameron for his message but said he was stuck back to back on calls and would try him later. the two did then speak on the phone. the reply on april the 23rd rejects mr cameron's proposal and goes on to say, i have pushed the team to explore an alternative with the bank that might work. no guarantees, but the bank are currently looking at it and charles should be in touch. best, rishi.

charles roxburgh was a senior official at the treasury. david cameron hasn't commented on any of this since questions were first raised in two newspapers several weeks ago, but ministers reject suggestions of wrongdoing. the former prime minister made contact with the treasury, the treasury throughout the pandemic have worked with a whole range of different businesses and stakeholders, but the correct processes were followed and in the end no money was provided to the company. it was turned down as a result of officials meeting them in the correct way. the chancellor insists he acted with integrity and propriety. labour disagrees. this is a complex story but it's been made more straightforward this evening with the publication of text messages. we need to see real answers from the chancellor as to exactly what has gone on. we need full transparency. we're concerned that he may have breached the ministerial code and we need an investigation to get to the bottom of that. david cameron once warned about the far too cosy relationship between politics and money.

there are rules about lobbying, but critics say they're not tough enough. tonight labour is piling the pressure on the chancellor, saying this raises questions about his integrity and his objectivity and even suggesting he might have broken the ministerial code. now, rishi sunak suggests any idea that he's done anything wrong, he says it is right that he and the treasury were listening to all sorts of ideas about things that might help companies during the pandemic and of course in this case what david cameron was suggesting was turned down. of course, when it comes to lobbying, all sorts of people make their case to politicians and government departments and of course not for the first time, many are now wondering whether all this is transparent enough. thank you. the mother of a 19—year—old student who was found dead in a pond in essex two weeks after being reported missing

says his disappearance wasn't taken seriously by police. richard okorogheye's death is currently being treated as unexplained. his mother, evidencejoel, claims her son was discriminated against because he was black. today, the police watchdog opened up an investigation as a matter of course. sangita myska reports. the search for richard okorogheye, accompanied by desperate pleas from his mother for his safe return, captured the country's conscience. the 19—year—old university student went missing two weeks ago. richard had sickle cell disease, yet he left his west london home on 22nd march, without a coat or his medication. he caught a bus at 8.45pm and was next seen on this cctv footage a short distance from epping forest in essex at 20—to—1 in the morning. his body was eventually found in this large pond. i worshipped the ground he walked on...

today his mother, who works night shift as a nurse, described the last time she saw her son. he said to me, "if you're going to work tonight, well drive safely, don't drive too fast, ok, drive safely, mummy." i said i would. he said, "i love you," i said, "i love you too." he held the door. he said, "mummy, i'll be going to my friend's." the metropolitan police say richard's death currently remains unexplained and that his body shows no signs of injury. his mother says that concerned about his vulnerability, including his need for regular blood transfusions were dismissed by the police. the way they treat me was disgusting. that's a very strong thing to say, why do you say that? everything i do was dismissed. it meant nothing. i was told by one of the officers i called, "if richard is in pain, as you say, he will find his way to the hospital." i said, "hold on a minute,

if richard is in pain, he can't move." richard's mother claims that his race was the reason for the alleged slow response by the police. because if that was somebody else, i feel that they would have acted... ..quicker, or quickly. when you say that, what do you mean, if he was someone else? if richard was a different colour, if he wasn't black, i know it's hard to say that, but the discrimination was quite obvious. responding to the allegations, the metropolitan police say they have worked tirelessly on richard's case, using the full range of their resources, including work behind the scenes. richard's mum does not believe he took his own life, describing him as happy and aspirational. richard was her only child. she is bereft. it's a big hole, a massive hole that can never be covered again. especially learning that maybe he will not walk through

that door any more. he will not walk through that door, my baby will not walk through that door again. to see him, to embrace him, say, "my mummy". oh, richard! richard had so much to live for. he had so much to give. richard's mother, evidencejoel, ending that report from sangita myska. president biden says he will introduce a series of measures to try and reduce gun violence in the united states which he says is at epidemic levels and an "international embarrassment". let's speak to our north america editorjon sopel, who's at the white house for us. always an incredibly difficult issue for a us president. what could he do differently? just for a us president. what could he do differentl 7, , ., differently? just look at the scale ofthe differently? just look at the scale of the problem, _ differently? just look at the scale of the problem, sophie. - differently? just look at the scale

of the problem, sophie. they - differently? just look at the scale l of the problem, sophie. they have already been 11,000 gun deaths so far this year already been 11,000 gun deaths so farthis year in already been 11,000 gun deaths so far this year in america, so 11,000 deaths at the hands of a gun in just over three months. now, you would have to say that whatjoe biden has proposed it's pretty cosmetic. he is saying you should know longer be able to buy a gun kit where there is no serial number and untraceable. an accessory for a revolver should be banned from sale. this is that the edges of the scale of the problem and joe biden would concede that. he wants more far—reaching legislation, but what he can do byjust signing a piece of paper is very limited. he needs to get congress to act and he says they should act now, but they won't. there are not the numbers there to get this legislation through so you have the american public saying for example, on whether anyone should have a comprehensive background check before they are able to buy a gun, well, the american public says, yes, they should, but the power of the gun lobby means that's not going to happen. the president is calling for action now. i think the chances of

that happening are slight in the extreme. jan that happening are slight in the extreme. , ., , ., ~ i. more than 320,000 people are now thought to have died in mexico with coronavirus. the authorities have updated their figures, which are some 60% higher than previously admitted. mexico has the third highest number of covid deaths after the us and brazil. our latin america correspondent will grant reports now from mexico city. ivan sanchez often takes his wife and children out to eat in a local cafe in mexico state. but these days someone is missing from their regular family lunches — ivan's father, mario. he fell ill from covid shortly after ivan got the disease. unwilling to go to hospital, he tried to ride out the virus at home — and died on this very sofa. ivan grapples with the grief and the guilt of having infected his father every day. many thousands in mexico have died like mario — untested, under the radar, and not included in

the official statistics. translation: after he died i asked a friend to help me l with the paperwork so his death wouldn't be registered as covid but as a respiratory collapse. we did it so we could give him a proper wake at home. as government data suggests a staggering 320,000 have died from coronavirus in mexico, public health experts believe cases like mario's mean the true picture is even worse. most families extra officially are arguing our number could be higher than that 320,000, that we may be about half a million dead. if such a dire estimate is true, mexico needs to vaccinate its people soon. in one of the worst hit municipalities, there was tentative hope and optimism as the most vulnerable received theirjabs. but nationally the criticism is there simply aren't

enough doses to go round, and there has never been a proper strategy in place to cope with the scale of the problem in mexico. veronica saw her parents vaccinated — a huge relief after her brother recently died from coronavirus. veronica blames president manuel lopez obrador for underestimating the pandemic from the start. translation: with elections coming he doesn't care about the virus. - he just wants to keep the economy moving because shutting it down would turn even more people against him. but keeping tourism afloat has had deadly consequences and now a new spike is expected after the easter break. social distancing at prayer, face masks at mass. as mexico mourns its dead only the us and brazil may have lost more. yet the final figure here may never truly be known. will grant, bbc news, mexico. a murder investigation is under way

after one of the uk's richest men was stabbed to death at his home in dorset. the hotelier sir richard sutton, who was 83, died yesterday evening. a woman in her 60s was also stabbed and remains in a critical condition. a 34—year—old man has been arrested on suspicion of murder. dorset police say he and the victims were known to each other. a doctor has told a court in america that the way police restrained george floyd against the street during his arrest in may last year meant he could not take in enough oxygen leading his heart to stop beating as he was pinned against the ground. martin tobin, an intensive care doctor, was giving evidence at the trial of the former police officer derek chauvin in minneapolis. mr chauvin was filmed kneeling on mr floyd's neck for more than nine minutes. derek chauvin denies the charges against him. tomorrow the trial is expected to hearfrom the medical examiner who carried out

mr floyd's autopsy. the foreign secretary dominic raab has condemnded what he's called the "bullying actions" of myanmar�*s military regime after the country's ambassador to the uk was barred from entering his embassy. kyaw zwar minn was locked out last night, saying the building in london had been taken over by the burmese military. but the foreign office said it had to accept the decision by the generals to remove the ambassador after he criticised the coup. as elections to the scottish parliament draw closer, young people across the country are considering which party they'll back on may the 6th. 16 and 17—year—olds are eligible to vote, and as our scotland editor sarah smith found, they're eager to hear bold ideas on education and climate change. they're also hoping to see more diversity in scottish politics. over 100,000 young people, like paisley art student 17—year—old isla, will be voting for the first time next month. like most of their age group, they support independence

for scotland and want more political focus on the environment. you need to get young people on your side so, number one, they don't lose interest in politics. and, number two, if you have a young person on your side, they have the probable pattern that they'll continuously vote for you. you know, who wouldn't want that under their belt? on the same day, the weather is radically different in aberdeen, where16—year—old david is concerned by the economic future and opportunities for those who risk becoming part of a lost generation. when i go to the polling station, i'll be thinking about a number of things, but mostly which party is going to rebuild scotland for the better as we exit this pandemic? who can lead the country out of the pandemic, focusing on the economy, jobs and opportunities for young people? we gathered together a group of under—18s, including david and isla, from all over scotland to explore their priorities in this election. after a year of school closures, education's high on the list. the big problem i have with it is the inability, it seems,

to reduce the attainment gap between the rich and the poor, the affluent and the less affluent, and that was compounded by the manner in which results were awarded last year after the coronavirus cancelled the exams. it was quite frankly shocking. education in this country is undoubtedly good, but there is always room for improvement. we now have the opportunity, as we recover from covid, - to take a look at our education system and say, what - is important in it? is it more about- learning about values? is it about learning how. to use your brain to make the world a better place? is independence a big issue for you? will it determine how you vote? i believe the union isn't working, although independence isn't the only solution to this problem. we could consider a new style of union. the main point that would lead me to support a second referendum is that decision for brexit. i'm in favour of remaining part of the united kingdom. - i believe there's many benefits to it and i wouldn't vote -

for a party that goes against that. these voters want to see parliamentary candidates from a more diverse range of backgrounds. we need people who are from poorer areas, we need people who are asian, black, trans, more gay people in politics. we don'tjust need more young people, we need more people of every type. the majority of people we listen to are middle—aged, white men who are straight and cis. what's the deal with that? the deal is, it seems, these under—18s know very well what they want and politicians would be well advised to listen. sarah smith, bbc news, glasgow. golf now and at the first round of the us masters — the first major of the year — conditions have been tricky and many of the favourites have struggled. among the uk contingent, rory mcilroy endured a frustrating day, finding the water here on the 13th on his way to finishing his round on four over par. lee westwood, bidding to become the oldest

winner of the tournament, fared even worse, finishing on six over par. the leaders are currently on three under par. next week more covid restrictions will be rolled back. you can go to the hairdresser at last in england. pubs and restaurants can start serving again outside, and in wales more shops will open and travel in out and of the country will be allowed. but shifting back to our old ways may not be as easy as we think, and for some, the weeks ahead are both exciting and daunting. daniela relph reports. i think i'm on the thin line between cautious and optimistic. come on up, get your cheese now. we just need the general public back to make the market blossom again. i i can't imagine going to the pub and mingling with everyone. i always have this thought in my head that, oh, my god, there are people too close to me. i think the whole population has been suffering - from lockdown fatigue. the regular rhythm of our everyday

is slowly returning. the familiar routines resumed. but for many, their mindset has shifted. i think there are some people who we probably will never see in church again because of what we've gone through as a society. it will be very hard for them to get their confidence back and going and doing normal things once more. memories of a life without restrictions — as freedom beckons, some find themselves conflicted. i think i feel a bit more anxious but i still like the idea that i can go out for drinks with my friends again, but, strangers, please stay away, you know? yeah, i definitely feel a bit anxious but i'm not too bad. normality will mean readjustment, especially if you feel forever changed. i think it's made me a bit more introspective, ifanything.

it's made me value friendships a lot more. enticing the crowds back in. it comes with responsibility and a need for reassurance. it's hard to imagine so many people close up together as scenes you would have seen in the past, and i do think we need to demonstrate that we have a safe environment, that we've thought about those issues. a thriving business and long waiting lists, but even then the weeks ahead will be edged with restraint. we're going to be busy. it's certainly going to be a change of pace because i have gone from not working at all to back into six days a week, full—blown life again. so i am a little bit nervous, i'd be lying if i said i wasn't, but i am trying to be optimistic — i think it's the best way to be. the message is both hopeful and careful, both optimistic and cautious, but everyone has that

thing that they crave.
