we begin the programme in sri lanka, holding a day of mourning for the victims of the easter sunday bomb blasts. more than 300 people were killed in the attacks on churches and hotels. many of the funerals are under way. a state of emergency has come into force. the country remains on high alert. on monday, more explosive devices and detonators were found. my colleague sharanjit leyl is in colombo. tell us more about today's day of mourning. well, that's right, sally. essentially it is a day of mourning. we expect to see more funerals take place. some took place yesterday, a day after the attack. it is also as you mentioned a state of emergency. that took effect at midnight, just a few hours ago. that gives the government authorities hear the

sweeping powers, in fact, to detain and arrest anyone that they consider suspect. now, sally, we know that these are the most violent, deadly attacks that shrill anger has seen since the days of the civil war —— sri lanka has seen since the days of the civil war. many questions are now being asked about why the government didn't act on warnings that an extremist group was about to attack. daybreak at saint sebastian's church. dozens were killed in the bombings here on easter sunday. today many of those victims will be laid to today many of those victims will be la id to rest today many of those victims will be laid to rest amidst tight security. the vast majority of those killed in co—ordinated suicide attacks against churches and luxury hotels were local people, but there were also at least 30 victims from overseas, eight of them were britons. ben nicholson survived the blast at the

shangri—la hotel but his wife anita, son and daughter were killed. mr nicholson said he his children shared with their mother the ability to light up the room. bill harrop and his wife sally, jp, were from manchester. died at the cinnamon grand hotel. his colleagues said he was a much loved and respected colleague who will be greatly missed. the attacks have been blamed on the local islamist group, national thowheeth jama'ath. there have been 2a arrests. but that group is said to have acted with the help of sofar unnamed international terrorists. 0ne minister called it a colossal failure of intelligence. intelligence never indicated that there is going to be an attack of this magnitude. they were talking about isolated, one or two, not like this. and besides, there is not emergency in this country. we can't

request of the armed forces to assist us. 0nly request of the armed forces to assist us. only the police. sri la nka assist us. only the police. sri lanka is wary of more attacks. this was a blast as police tried to diffuse explosives inside a van. no—one was hurt. interpol is deploying investigators to sri lanka. the us is closely monitoring the situation as the hunt for the foreign terrorists who may have masterminded these attacks gathers pace. now, of course, we know, we are getting reports that in fact the death toll from those tragic glass across columbo, there were three luxury hotels and a number of churches targeted as well —— colombo. we have had reports the death toll has risen to 319. and of course more than 500 remain critically injured as well. we are

also getting reports that nearly a0 people now have been arrested in links with this blast. we know yesterday the authorities suggesting that it was a little—known extremist group called the thowheeth jama'ath who were involved. they are still looking into that. the chief question being asked isjust how much the government knew and when. there are reports that they were warned about this as early as a month ago, but didn't act on it. all right, thank you for now, sharanjit. i will speak to you again in ten minutes for more detail on the final point that you made about what the government knew, but in the meantime let's discuss what the trump administration has declared. any country importing iranian oil after may the first will face american sanctions. the us pulled out of the international nuclear deal with tehran last year, and this puts further pressure on iran. it will also affect china, india, south korea and japan,

who were given waivers to buy iranian oil to limit market disruption. 0ur north america correspondent david willis reports. poil — poil - it poil — it is the main source of revenue for a run, a country already facing a deep recession. now, in an attempt to accelerate that decline, the donald trump administration is looking to cut that source of revenue by forcing the purchases of uranian oil to look elsewhere. —— uranian. china and india, two of iran's biggest customers, along with japan, south korea and turkey will each face punishment if they continue to buy oil from iran. each face punishment if they continue to buy oilfrom iran. as the united states seeks to turn the screws on its main adversary in the middle east. before our sanctions went into effect iran would generate as much as $50 billion annually in oil revenue. 0verall today we estimate that our sanctions have denied the regime well north of $10

billion. the regime would have used that money to support terror groups like hummus and hezbollah and continue its missile development in defiance of security council resolution 22 —— hamas. defiance of security council resolution 22 -- hamas. the us slapped iran with sanctions after stepping away from the treaty aimed at reducing iran's nuclear programme nearly a year ago, but this latest move could strain relations with some of its closest allies — china in particular — with whom the united states is still trying to strike a trade deal. china has expressed its opposition and it is not alone. translation: we are against such impositions. it is not easy for those countries including turkey that are diversifying their oil resources . that are diversifying their oil resources. the us is taking a decision unilaterally and imposing it on other countries and making them pay the consequences. one potential beneficiary of all this, saudi arabia, with whom president trump has established a burgeoning

alliance, despite misgivings over the kingdom's poor human rights record and its role in the assassination of the journalist jamal khashoggi. saudi arabia and others in opec will more than make up others in opec will more than make up the oil flow difference, tweeted the president defiantly. but a shortage of oil could push up prices at the pumps and hurt the global economy. this latest move has already sent oil prices to a six—month high. let's brief you on some of the other stories making the news. the bbc understands the white house is to announce a state visit to the uk by president trump. it's thought it could coincide with the 75th anniversary of d—day, so around june the sixth. he made a four—day official visit lastjuly. the dissident irish republican group, the new ira, has admitted killing the journalist lyra mckee in northern ireland on thursday. ms mckee was shot dead as she was observing rioting in londonderry. the group apologised to her family and friends saying she was killed while standing beside

what it called enemy force at least eight people have been killed in a powerful earthquake on the island of luzon in the philippines. dozens are feared trapped in buildings in pampanga province, north of the capital, manila. the quake, magnitude 6.1, caused structural damage to clark international airport and made office buildings sway in manila. the duke and duchess of cambridge have released new pictures of their youngest child, prince louis, to mark his first birthday. the photos show the young prince in the grounds of their norfolk estate and were taken by his mother kate. samsung is delaying the release of its folding smartphone just days after reviewers said screens on the devices had broken. samsung says it will be running

further tests on the galaxy fold. the firm has not said when the phone, which costs more than $2,000, will go on sale. independent analyst stephanie harejoins me now. it is great to see you, stephanie. we do expect hiccups with brand—new tech. what do you make of the news? the fact it has been in development for eight years and has had this problem isn't great. this is not going to be their flagship problem isn't great. this is not going to be theirflagship phone, it won't bring samsung its fortunes. that will be the 5g phone that they have released. that is where the future of technology lies. the folding phone is fun, it is a gimmick. iam folding phone is fun, it is a gimmick. i am not sure what problem it solves. the 5g phone is it. gimmick. i am not sure what problem it solves. the 56 phone is it. the problem is... if you unfold that you can watch a programme on the train. you fold it up and it is small and it fits in your handbag or whatever. your pocket perhaps. but i remember when they launched, they haven't

launched it, when they said this is in the pipeline, it is soon to be available, everybody was asking how do we know it is going to survive being opened and closed over and over again? being opened and closed over and overagain? i being opened and closed over and over again? i immediately thought of small children who are always trying to grab your devices and play with them. will it survive the toddler test? it sounds like it didn't, there is a protective peel that needs to be kept in place and people kept peeling it off and then it is possible that substances will get behind the screen and it won't survive on impact. can it survive outside the lab in real conditions? kids included. indeed, absolutely. we will watch this space. stephanie is back later. i have asked if you are is back later. i have asked if you a re early is back later. i have asked if you are early adopters of tax. most of you are telling me that you think it isa you are telling me that you think it is a bad idea to buy tech from the get go because it's so expensive as well. keep your comments coming in.

we will mention them later. let's look at some other stories now. kim jong—un will soon travel to russia for his first ever meeting with president vladimir putin, according to north korean state media. while no specific date has been announced, the kremlin has also revealed the two will meet "in the second half of april". laura bickerjoins us from seoul. so this meeting could be pretty eminent? yes, i mean, we are expecting widely reported that it could be at the end of this week. we have had no official confirmation. what we have had in the last few hours is the first north korean confirmation that kim jong—un will travel to to see vladimir putin in russia. we are hesitating to announce where it might be. at the moment what we are hearing is that it could be in vladivostok because the russian president vladimir putin is due to travel to china and it is

widely reported that he might want to stop off in vladivostok for that meeting which the border town, the port town is very near the border with north korea so it could be that thatis with north korea so it could be that that is the venue for the summit, but it is interesting timing for kim jong—un to go and meet the russian president at a time when the relationship with the united states certainly isn't great after the colla pse certainly isn't great after the collapse of those talks in hanoi. it does seem that kim jong—un might be exploring other options. we shall watch this space. thank you for now, laura bicker, in seoul. stay with us on bbc news. still to come: convenient and now eco—friendly, engineers discover a way to recycle the disposable nappy. the stars and stripes at half—mast outside columbine high. the school sealed off,

our headlines: the united states threatens sanctions on any country importing oil from iran after the first of may. tehran calls the move ‘illegal‘. and our top story — a day of national mourning is taking place in sri lanka following the deadly bombings that killed nearly 300 people. the official death toll has now reached 310. let's stay with that now. firstly, you have been looking at the newspapers of the day there. talk us through the headlines. essentially there is nothing else on the front page here and, of course, global agencies around the world continue to report on this as well. the daily mirror, the layerjust paper in sri lanka isjust all black as you can see and just these tiny

lines at the bottom that say in remembrance of all those who lost their lives on april 20 one, 2019. easter sunday, of course. and this is another newspaper here. essentially it is a financial paper but of course the blame game over terror attacks is their main headline because there are so many questions being asked aboutjust what the government knew and when and why they were unable to act on these warnings that they were given. that is the real crux of the issue. two days after the fact, people have woken up to a state of emergency. today that took effect at midnight and there are many questions being asked about what the government knew. they were warned in early april, according to reports. there we re april, according to reports. there were international agencies warning them that an attack like this was about to take place. essentially what we are being told and what we have been hearing here amongst the

cabinet, the press secretary and the spokesperson who gave the conference yesterday suggested that the prime minister was actually left out of intelligence briefings and kept in the dark along with his team because ofa the dark along with his team because of a rift with the president which developed last year. as a result he simply did not know what was going on. it is yet unclear as to what was done with that information. they obviously knew about this particular group, national thowheeth jama'ath a little—known extremist group here in sri lanka. they are thought to be behind the vandalism of some buddhist statues last year, this is a predominantly buddhist country. but nothing was done to act on this. and there are many questions being asked and a lot of anger amongst the people here, many of whom are still grieving and are in shock because

they have not seen this scale of violence for a decade now is the end of the civil war in 2009. you very much. more details online on that story. let's pause for a moment and ta ke story. let's pause for a moment and take in the latest sports news from the bbc sport centre. hello. i'm marc edwards and this is your tuesday sport briefing. we start in the english premier league where sean dyche's burnley were the party poopers at stamford bridge, putting a spanner in chelsea's quest for a top a spot. the hosts held to a 2—2 draw. it does mean chelsea are up to ath but missed the chance to go 3rd ahead of tottenham hotspur who have a game in hand now. we wa nted we wanted to win, obviously and obviously they did not want to lose. what we are unhappy is that we believe there was too much time

wasting in the second half and there wasting in the second half and there was not enough to compensate for that in our opinion. over in italy, what has happened to napoli? carlo ancelotti's side on an absolutely dreadful run of form. they lost 2—1 at home to atalanta. so it means they've now gotjust the one win in 7 matches in all competitions. but for atalanta they've really surged into contention for a top four finish. napoli remain second, six points ahead of inter milan while atalanta move level on points with ath placed ac milan. tottenham hotspur have the chance to consolidate their third place in the table when they face brighton later on tuesday. with manager mauricio pochetttino saying its in their hands to be in the top four at the end of the season. here's cheeky little stat for you — spurs haven't lost a premier league home game on a tuesday since august 2007. to the nba and it's tight in the play—off series

between the denver nuggetts and the san antonio spurs. the two teams are tied at two—games each in the best—of—seven series. the momentum is with the nuggets after their victory in game four on the road which may have turned the tide on the series and they'll hope to continue that later on tuesday. ronnie o'sullivan is in danger of falling victim to one of the biggest shocks in crucible history as he trails amateur james cahill 5—a in their snooker world championship first—round match. cahill needs five more frames for victory when the match resumes on tuesday. debutant qualifier cahill is the first amateur to play at the crucible and showed great resilience to stay in the match. o'sullivan's performance became increasingly error—strewn and he's got a job on his hands to bounce back in this one. and time to show you what's been catching our eye on social media. and it was all about team usa in the finals of the world indoor skydiving championships in lille. indoor sky diving, i hear you say.

how is that possible? well, like this. with the use of this lovely wind tunnel. more than 30 countries, and over 250 competitors took part. team usa snaffling 3 golds including one for the 12— and 13—year—old siblings noah and kayleigh wittenburg who took the title in the dynamic 2—way open. you can get all the latest sports news at our website — that's bbc.com/sport. but from me marc edwards and the rest of the sport team, that's your tuesday sport briefing. they're easy to use, relatively cheap and sold in the billions — but once disposable nappies have been used, they form one of the largest types of waste. and unlike bottles or cans or cardboard, nappies are hard to recycle. but now engineers have devised ways of recovering the plastic and other materials inside them. a pilot plant has opened in treviso in italy, backed by the world's largest maker of nappies procter & gamble, as our science editor david shukman reports.

time for yet another nappy change. this two—year—old gets a new one regularly. the world uses 187 billion of these every year and most end up burnt or in landfill. here in matt three in italy, her mother says she cannot help adding to the mountain of nappy waste. i tried organic cotton but it was difficult with three little ones to keep up with three little ones to keep up with that. just up the road there is a new attempt to do something with all those disposable nappies. they are brought to a special recycling centre. most of us would prefer not to think of dirty nappies but here they are welcomed. the first step is to reduce the smell. then there is

the task of sterilisation. nappies are put through a series of processes . are put through a series of processes. the first step is to separate their contents which i sent off toa separate their contents which i sent off to a sewerage farm. what is left is then sterilised with intense heat and steam before being dried out in this oven. i can feel the heat coming off it. the material is then divided up to be resold to different industries. at the end of the process there are three different kinds of material. amazingly, by this stage they are all clean so they can be turned into everything from plastic clothes pegs to cat litter. the man who came up with this idea used to design nappies. when i was changing my young kid i a lwa ys when i was changing my young kid i always felt i was throwing away something useful because i know as a designer of the products, i know what i put in these products in the first place. so it did not seem

right to throw away such valuable materials. another batch freshly sterilised. the project is supported by the world ‘s largest maker of nappies, procter & gamble. it is under pressure to reduce its impact on the environment. so it wants to open nappy recycling plants in britain and around the world. maddalena's nappies will soon start to be recycled in the hope is that this idea will quickly catch on. so there you have it. there is hope for all of us if we can recycle nappies. steps in the right direction, aren't they? we have more coming up in is this

—— coming up in business reefing. we've also been hearing a lot from you about whether or not you are an early adaptor of technology. well, there is some good news on the weather front if you have been enjoying the fine weather in the last few days. we have one more day of decent weather on tuesday, a lot of sunshine around and temperatures still into the 20s. after that it really will be all change. in fact, it will cool off dramatically and we have showers and thunderstorms potentially on the way. on the satellite already, the picture is looking very u nsettled. you can see clouds swirling around here. weather fronts as well, patterns actually, but these weather fronts are heading in our direction and in around 2a—36 hours time they will arrive and we will see downpours. first in the country's south—west and then in other parts of the uk as well. for the time being, tuesday

looks relatively quiet, notjust in the uk but in much of western, north—western europe into scandinavia as well. morning temperatures are between six and 12 celsius though not as chilly as it was yesterday morning. and then in the afternoon it is business as usual. a lot of sunshine around, warm south south—easterly wind, not quite as warm. we had temperatures around 25 degrees in the last few days and i think around 22 or 23 across southern and central areas. still making around 20 in the lowlands of scotland and just shy of 20 for belfast but another fine day on the way. here is tuesday night into wednesday and the high pressure that has been bringing us the fine weather slips away towards the east and this big area of messy weather with its weather fronts, this big area of low pressure is starting to push in. from the early hours of wednesday we will start to see rain moving into cornwall, devon, parts of wales as well, central and southern england and the midlands as well some could be downpours with thunderstorms and watch what happens through the day on wednesday.

difficult to say which towns and cities will get the downpours at what time but suffice to say it will be a lot more unsettled on wednesday compared to the last few days. scotland is still looking fine but the north sea coast may be a little on the cool side there. some cloud as well. that is midweek — towards the end of the week it really will be a big change because we even say goodbye to the mild air. the warm air is long gone but colder currents of air from the north atlantic arrive, breezy conditions as well, showers possible. so the outlook says it all, really — a lot of shower symbols here with temperatures dropping to below average for some of us and towards the weekend even struggling to make double figures across northern areas.

this is the business briefing. i'm sally bundock. twitter unveils its latest numbers, but will efforts to increase security and stop trolling damage its bottom line? foldable failure — is samsung's new phone a galaxy away after the korean tech giant delays the launch of its new expensive device? let's look at financial markets. you can see it is flat. a long weekend around the world. the price of oil is pushing up the energy
