we start in northern ireland where detectives are questioning two men in connection with the murder of the journalist lyra mckee. the 29—year—old was shot dead as she was watching rioting in londonderry on thursday night 21 years after the good friday peace agreement was signed. the suspects, who are 18 and 19, were arrested under the terrorism act. officials say they believe a dissident irish republican group, the new ira, was behind the killing. from belfast, louise cullen reports. a journalist, campaigner, beloved partner and devoted daughter. the police today said they'd met lyra mckee‘s family to try to answer their questions and they said the killing had united the community against the dissidents. my broader concern is that

what we're seeing is a new breed of terrorists coming through the ranks. and that, for me, is a very worrying situation. there is a real sense that what happened to lyra marked the sea change, and i want people to have the confidence to come forward. in connection with the murder of lyra mckee. they were brought here to belfast for questioning at the psni serious crime suite in musgrave police station. they're being held under the terrorism act. the police were carrying out a search operation targeting dissident republicans in the creggan area of derry on thursday night when rioting flared. in cctv footage, a masked man steps out from behind a wall. he disappears. then a few minutes later, a man with a gun fires shots towards police and onlookers. lyra mckee was rushed to hospital where she died from her injuries. police believe a group calling itself the new ira was behind the shooting. one of the things that's worrying about this organisation is that they do have people

who were experienced in the dark arts of bomb making, when they were in the provisional ira, and some of those people have gone over to the new ira in the last decade or so. for friends of the journalist and lg bt activist, reality is just beginning to sink in. when i woke up this morning, i did think that i dreamt all this, it hadn't really happened. i'd dreamt the vigil, i'd dreamt everything and then i heard the news and i realised that it wasn't some awful nightmare, it was true. and people across northern ireland are standing with lyra's family and friends with books of condolence being signed and vigils held in a number of towns and cities. everybody should show their condemnation of this murder in some shape or form. we need to move forward, and that nobody wants to go back to those dark days, and that our children deserve the opportunity to never be brought up in that, the way we all were. the community has been brought together to stand against that possibility by the killing of a woman who called herself

a ceasefire baby. louise cullen, bbc news. there've been clashes between demonstrators and police in paris on the 23rd saturday of yellow vest protests. officers fired tear gas and arrested nearly 200 people. the protesters have been banned from the area around the champs elysees and notre—dame cathedral. our europe regional editor danny aeberhard reports. chanting it's week 23 of the yellow vest protests, and the first since monday's catastrophic fire in notre—dame cathedral. but if the authorities hoped that that disaster heralded a moment of newfound unity, they were wrong. political tensions continue to smoulder, erupting into clashes on the streets of paris. a group of protesters set motorbikes alight in one area. the violence was nothing like the scale of the riots in december. one protester said radical elements had hijacked a mostly peaceful demonstration.

translation: you can see that there are people who are not necessarily here out of the same convictions we have, for peaceful reasons. we should be able to move around everywhere, but it's true, it's not very pleasant doing this. we can't protest as we would like, so it's getting tense. anger remains, though. some of it this week was directed against the colossal sum, about $1 billion, raised in just days to restore notre—dame. demonstrators have criticised the ease with which billionaires and corporations have funded huge donations for the fire—damaged cathedral rather than to alleviate poverty. danny aeberhard, bbc news. meanwhile, hundreds of extra police officers have been drafted into central london to help clear climate change protesters from the capital's roads. more than 750 people have been arrested since the demonstrations began on monday. the metropolitan police have defended their handling of the situation, describing the operation as unprecedented.

jon donnison reports. the extinction rebellion has life in it yet. for a sixth day, climate change protesters targeted central london. yesterday's pink boat at oxford circus was replaced by a green hammock. their message: they're not going away. if there were a better way, please, somebody tell us because we've tried the suggested ways. we tried writing to mps, we've tried doing petitions, we've tried just standing in the street with banners. it clearly hasn't worked. cheering she was eventually arrested, as were others, but they're not making it easy for the police. some protesters had glued themselves together with their arms encased with piping. a cheer goes up now as one protester has been released. here at oxford circus, the police are using bolt cutters, angle grinders and special chemicals

to break through the glue that protesters have used to stick themselves together. cheering there were similar scenes at waterloo bridge. we were here to protect our kids and to protect our future kids and their future kids, and you don't have to understand science to understand that. the metropolitan police have had to request 200 extra officers from neighbouring forces, but deny they're struggling to cope or that cells are full. it's been a really challenging operation. they're using very dynamic communications and very dynamic tactics. i think many people would say we haven't seen anything quite like this in this city or around the country before. by late afternoon, the last of the protesters at oxford circus had been removed and traffic was flowing again. you are suffocating me. you are drowning me. but as dusk fell at waterloo bridge, some demonstrators were preparing

to bed down for the night. in the morning, they'll be back. jon donnison, bbc news, in central london. let's get some of the day's other news. authorities in the us have arrested a man suspected of belonging to the militia group, which has been stopping migrants trying to cross the country's border with mexico. 69—year—old larry hopkins has been charged with illegally possessing a gun and ammunition. it comes just days after a video was released of a vigilante group detaining dozens of migrants in the desert. they have been widely condemned by civil rights groups and local officials. commemorations have been held in the us state of colorado to mark the 20th anniversary of the mass shooting at columbine high school in which 13 people were killed. the gunmen, who were students at the school, finally turned their weapons on themselves. flowers and cards have been laid at a memorial to the victims in the suburb of denver. there's been heavy fighting south

of the libyan capital, tripoli, after soldiers loyal to the un—backed government said they had launched a counter—offensive against general khalifa haftar‘s forces. more than 200 people have died since general haftar began his attempt to capture tripoli two weeks ago. rami abukalam has the story. this is south of tripoli on saturday as forces loyal to the internationally recognised administration tried to push back against general khalifa haftar bosman troops. it followed days of fighting in which neither side made significant advances and in which more than 200 people were killed. as the counter—attack was under way, fighters loyal to the government spoke of theirfires. translation: today we and fads - in advance. moral of fighters is really

good and god willing we will advance and reach general khalifa haftar‘s home. i have condemned the muted international response. russia, egypt and the united arab emirates are all supporting general khalifa haftar who also appeared to receive the backing of donald trump in a phone call earlier this week. many foreign powers think he has the potential to stabilise libya from its post— revolution chaos. some libyan people feel the same, but others think he is just another wardlaw determined to win power by force. meanwhile, the fighting intensifies with each passing day. a un resolution drafted by the uk calling for a ceasefire was rejected by both the us and russia. people in ukraine will vote on sunday in a presidential election that could see a comedian and tv

star become their new leader. volodymyr zelensky, who until this campaign, had no political experience, is challenging the current president, petro poroshenko, who's been in power since 2014. the bbc‘sjonah fisher reports on what's been an extraordinary campaign for the ukrainian presidency. singing just like at a football match, the supporters are being segregated. this is where they split them up. there is a sign here. if you are for volodomyr zelensky, the comedian,

you go to the green side. if you support petro poroshenko, the president, the fan zone, it's the purple on the right. this is the olympic stadium in kiev, where the champions league final took place last year. it has now been split in half. on that side are supporters of ukraine's president, petro poroshenko, and then there is a line of police and on this side here, supporters of volodomyr zelensky. chanting as you might expect,

when you hold a debate in a football stadium, well, the crowd are getting involved. every time one of the candidates says something which the other supporters do not like, very loud boos and big reactions. after 60 minutes, less than the duration of a football match, this debate is over. going into this, mr zelensky was the big favourite to win on sunday. we will have to see whether what happened here makes any difference to that. we will keep an eye on that, and bring you all the updates as they happen. stay with us on bbc news. still to come, alive and buzzing: how 200,000 bees, living on the roof of notre—dame cathedral, survived this week's inferno. the stars and stripes at half—mast outside columbine high. the school sealed off,

this is bbc world news. the latest headlines: police in northern ireland warn a new breed of terrorist is coming through the ranks. they're questioning two men in connection with the killing of thejournalist, lyra mckee. french police fire tear gas and arrest more than 100 people during the latest anti—government yellow vests protests in paris. in sudan, the country's public prosecutor has begun an investigation into former president omar al bashir on charges of money laundering. millions of dollars in cash were allegedly discovered, hidden in sacks of grain at his home. mr al—bashir was ousted from power last month, following months of protests and a military coup. meanwhile there are reports military authorities have arrested several of the most senior figures from the party of the deposed president. a little earlier i spoke to suliman baldo — a sudanese academic that served as an adviser to the un on the darfur conflict. i began by asking why omar al—bashir

would have such large quanitites of cash one major reason president bashir was very stubbornly resisting stepping down despite all the rejection by the population is that he didn't want it to be exposed as to how much level he is involved personally, and members of his family, in massive, mega corruption. that is a major reason for the economic crisis in the country. that's why he was fighting to the bitter end. however, this stash cash that was discovered in his home would be only the first, i am sure, given how deeply he is involved in corruption at that level. what would he have done with it? was he keeping it in case he needed it? would he have used it

to run the country? he would have used it to maintain a very elaborate patronage system, buying loyalties of tribal chiefs, of warlords, so that they remain loyal to him and to the money they are receiving from the regime, to also divide armed groups that are resisting government in peripheral areas of sudan and to split up and break up opposition parties that are standing up for their principles. these are the traditional, well—established political parties in sudan who have been weakened over 30 years of manipulation through these attempts of patronage and buying of influence among the influential members. well, omar al—bashir remains injail. meanwhile, there are discussions between civilians and the military for a transition to civilian rule. is there a chance that the military is going to lose patience with these

discussions and simply unilaterally decide to maintain rule over the country? i don't expect that to happen. the military council has pledged to the population and to the international community that it will not dissolve the force to try and break up the civil protests that are continuing even as they took power and deposed bashir. they did depose bashir i believe in an attempt to change figureheads but to maintain the system of corruption, of repression of the sudanese people by their own army. however, the population is not buying that and that's why the protests are continuing, they have succeeded in deposing bashir, they have succeeded in deposing the general who succeeded him within 2a hours, and general burhan who is the head of transitional military council today is on notice. and the head of the council today is on notice. either he responds to the people's demands for a transfer to a transition led by civilian

authority, or there will be general disobedience in the country that has paralysed the country for the last few months. this is what you are going to witness over the coming days. kosovo has allowed a group of its citizens to return home from syria. four men suspected of fighting for the so—called islamic state were arrested when they landed. the collapse of the group has cast a spotlight on the issue of repatriation for many countries. kieron mirchandani reports. from the rubble of syria to a caged playground in kosovo. 110 people, mostly women and children returned home on saturday, swapping the desert of the caliphate for metal wiring as their cases are processed full of kosovo is the latest country forced to deal with issues of repatriation of citizens who now wish to return home. while islamic

state has been virtually defeated, many worry that those who return may still retain the destructive ideology. kosovo's top officials say returning them home — make allowing to return home is an important step. translation: will not stop before bringing every citizen of the republic upon kosovo back to their country. and anyone who has committed a crime or part of these terrorist organisations will face the justice. since 2012, terrorist organisations will face thejustice. since 2012, over terrorist organisations will face the justice. since 2012, over 300 kosovo and is made the journey to syria according to government figures. police estimate that 30 people remain. those are returned on saturday were alleged fighters, a0 of them. they were arrested on arrival. kosovo was not the only country dealing with the issue of repatriation. the uk government allowed to return a british bride to return to the uk, stripping her of her citizenship. france has allowed the children are fighters to return.

for many countries, the question is how to deal with returning members of the caliphate while maintaining security of the state. it is a quandary you have an answer to. —— if you have an answer to. nearly 10% of heart attacks and strokes could be prevented in england and wales — if health checks were tailored to individual patients. currently people over the age of a0 are eligible for a heart check, every 5 years. but new research from university college london, suggests that high risk people should be screened more often — and low risk patients much less. our health correspondent, james gallagher reports. somebody‘s risk of a heart attack or stroke can be worked out by looking at risk factors such as their blood pressure, cholesterol levels orfamily history. doctors use the information to give advice on lifestyle changes or to prescribe drugs like cholesterol—lowering statins or for blood pressure. the study followed 7,000 people to see how their risk changed over time, and then investigated whether there was a better way of performing routine check—ups. currently, people should be

seen every five years, but the study suggested the healthiest people could be seen every seven years, the less healthy, every year. the ucl team predict 8% of heart attacks and strokes will be prevented with tailored testing. that works out at about 5,000 fewer heart attacks and strokes a year in england and wales. the researchers say these personalised checks would not cost the nhs any more money. the british heart foundation said the approach could potentially save lives, but warned it could be hard to implement and that too few people were having the current assessments. james gallagher, bbc news. ajapanese sailor has become the first blind person to sail a yacht across the pacific ocean. mitsuhiro iwamoto left california in the united states forjapan two months ago. caroline rigby tells his story. it came into view as a small dot on the horizon, a a0—foot yacht carrying the first blind person

to sail across the pacific, nearing the end of an epic 1a,000—kilometre journey and two months at sea. as they neared dry land, people gathered at the dock at fukushima in japan to welcome them. mitsuhiro iwamoto, a japanese citizen who lost his sight at the age of 16, set sail on february 2a from san diego, where he now lives. thank you for coming. he steered the vessel, a sighted navigator doug smith assisted him with verbal guidance on potential hazards and wind direction. mr iwamoto's first attempt at the crossing ended in disaster in 2013 when his yacht sank after being hit by a whale. so the 52—year—old was overjoyed to finally complete the challenge. translation: it was really tough and i realised that the pacific ocean is boundless. i've had enough, so i will not sail yachts for a while. they celebrated reaching land

with a hot shower and a cold beer, safe in the knowledge they've also raised money for charities to help prevent diseases which cause blindness. caroline rigby, bbc news. close to 200,000 bees that live on the roof of notre dame cathedral in paris have survived the devastating fire which destroyed much of the building on monday. three hives are still intact — experts say that the smoke is likely to have made them "drunk". hugh schofield reports from paris. for six years, they've been keeping bees on the roof of notre—dame. the inferno, one might have thought, should have reduced the three hives to a large pool of wax, but no. this brief video taken this afternoon shows that all is still in order. the day after, we had pictures taken by drones, and i could see the three dots made by the roof of the hives, and nothing was in front, nothing that looked like melted wax. and then on thursday, nicola, my boss, met andre on the pavement and he said he'd seen bees going back and forth into the hives.

luckily, the hives were not on the part of the roof that burned, but on the sacristy, a much lower level, visible here in the foreground. night was falling when the fire broke out, so the bees should have been settling down to rest. i was first very pleased, but facing them, they were on earth before us and they will be after us, i am definitely convinced of that, even with whatever we do, pesticides, i am always positive and i know that they will survive definitely. christian writers of antiquity saw bees as an inspiration for the church, a community of workers toiling for a common good. easter time at notre—dame, they are providing another symbol of life and hope. iam sure i am sure those beekeepers are

thrilled. stay with us here on bbc news, we have more coming up but you can reach us on twitter in the meantime. hello. after two days of easter weekend warmth, you may be watching this to see if it is set to continue for the rest of the weekend. the short answer is yes but keep watching now for the longer answer. this is the view from oxfordshire earlier where it was a chilly start for saturday. warm in the sunshine again and the weather front close to north—west scotland, giving some outbreaks of rain and more cloud to parts of ireland, but that backs away by monday. even here, we will see the return of the sunshine. this is how we start easter sunday, still with some outbreaks of rain in the northern and western isles, maybe a few mist and fog patches towards eastern parts of england, but where some spots will start the day close to freezing for a touch of frost. temperatures rebound in the sunshine

across england and wales, the hazy sunshine for northern ireland and for some of those in scotland, the vast majority is dry for the northern and western isles, again, some outbreaks of rain a time. breezy here, cooler than elsewhere in the breeze still keeping some north sea and english channel coasts cooler than elsewhere but you have the sunshine, most of us high teens and low 20s, some spots near the mid—20s, giving the warmest easter sunday on record a run for its money. pollen sufferers, though, know it is quite high out there for tree pollen so, yes, some of us are suffering as a result. this is how it looks through sunday night and into easter monday. still with outbreaks of rain towards the western isles keeping it breezy here as well. elsewhere, though, it is mainly dry and clear and low single figures in cooler spots in parts of eastern england and, again, it could turn misty in a few places. easter monday, this is how this is shaping up. notice the difference between northern and western scotland. that weather system, as we saw earlier, has backed away, so we are back

in the sunshine here. there will be an increasing breeze and more in the way of high cloud pushing in from the south during easter monday so sun will be increasingly hazy. temperatures for some of us may not be quite as high so much as many of us will notice. it will still be a fine, warm day for getting out and about. now, this is how it looks as we go through the next few days after easter. notice we start to get low pressure taking over, weather fronts heading our way from the and that will bring a change after the easter weekend. more cloud around, increasing chance of showers and thunderstorms and we'll start to see temperatures coming down. but that will be a gradual process. you can see it all under way here. if you want some rain on the garden, there is hope, especially during the second half of the week.
