they say it happened while special agents tried to serve arrest and search warrants at a home this morning in provo. president biden is scheduled to visit utah this week. let's go to our north american correspondent who has the details. what can you tell us? reporter: the details that we've got so far is that the individual, the suspect is named craig robertson. we understand he was 75 years old and there's a criminal complaint that -- complaint that shows that he was being invested for a few things, notably for making threats against president biden and f.b.i. agents had conducted surveillance on his home back in march. they wanted to talk to him about thinks social media posts. he told them, according to the criminal complaint to come back with a warrant, which they did. in terms of the social media posts, reading the criminal complaint, it's full of really dark messages, his social

media. violence towards president biden, other notable democrats, also galorifying gurns. just to read you one thing from the criminal complaints that's a message that f.b.i. agents obviously took very seriously. he put i hear biden is coming to utah so i cleaned the dust off the m-24 sniper rifle. we don't know the details of what led to the shooting. some law enforcement sources say there was a gunfight of some kind and the f.b.i. is now reviewing the case. as you mentioned, president biden is due to visit john thompson. the first time he'll be visiting the state since he became president. no comment from him or the white house yet on this. >> thank you. let's go to the u.s. state of hawaii where wildfires have turned deadly on the island of maui. at least six have died and authorities warn that number could go up.

several wildfires are burning cross parts of maui and the big island. eyewitnesses describe the scenes as apock littic. evacuations are underway for more than 13,000. the u.s. coast guard says it rescued 14 people including two children after they tried to escape the fire by jumping into the sea. about 2,000 travelers two and fro maui had to shelter in the airport overnight. the fires are fueled by winds from hurricane dora, which is passing hundreds of miles south of hawaii. fire crews are tackling fires on multiple sites but one gusts of up to 80 miles per hour have grounded firefighting helicopters. the governor of the state has issued an emergency dollar declaration. >> anytime things like this that shake our community, it's the communities and it's our

families, it's our people that help each other and this is a time we need help. we need to stand together, be brave for each other but at the same time it's just with sadness and just -- so we are just struck by the devastation felt in maui. >> governor josh green is returning home to the islands but wrote in a statement that he has been in touch with the white house. he said we expect to submit a request for a presidential disaster declaration in the next 36 to 48 hours once we know how vast the damage is. our state appreciates the incredible outpouring of concern and prayers from the mainlyland. we won't forget the aloha you have already begun to share with us. those wildfires and nose raging in portugal are the latest in a series of fires we've seen around the world this summer. last month on the greek island

of rhodes, thousands of tourists had to three their hotels has wildfires averaged the holiday hot spot. la palma fires forced thousands from their homes there and smoke from wildfires in kan drifted down as far as new york where the sky turned orange. so just what's the science behind these fires and what impact are rising temps having on their size and location? here's our environment correspondent. >> from siberia to spain, across parts of china and the u.s., severe wildfires have raged this year as never before. in 90 locations around the world this year lives have been lost as fierce flames have push turned holmes, holds and businesses into ashen cinders. often the spark of ignition comes from a human hand or a national event like lightning

but scientists are clear that rising. the are increasing the conditions in which these fires can thrive. the times classified as when vegetation can grow most slowly and fires the burn more fiercely. most clearly in the mediterranean region where fires driven biheat and winds are turning forests into dark, burning landscapes. >> we're not only seeing one of the fastest increase of temps in the world but a lot of future deforestation. we have less grazing, more vegetation growth and that makes the landscape even more flammable. >> closer to home, all parts of the u.k. are expected to come become more susceptible to wildfire as the climate changes. here in wales, they've already seen over00 quite fiers this

year. including here on revis mountain. >> the fires before were milder. now we're moving into summer fires. the fuel and ground dries out. we're having long periods of low rain and the fires become a lot harder to put out. >> forest fires also release huge amounts of carbon back into the atmosphere in. kan, c02 emissions from wildfires from january to july were more than double the previous record for a whole years. that extra car born boosts warming and likely exposing millions more people around the world to this growing threat of wildfires. >> staying with environmental matters, let's go to south america where the second and final day of the amazon summit, aimed at protecting the rain forest is ending. on tuesday, the eight countries sharing the amazon signed a

declaration agreeing to work together to fight illegal logging, mining and organized crime but there was no date set to end deforest station as the brazilian perspective had advocated. in his closing remarks on wednesday. lula pledged that the eight amazon countries will work together to fulfill their financial pledge to help protect the environment. >> it's not brazil that needs money. it's not colombia or venezuela that needs money. it's name. that industrial development over 200 years has polluted that needs them to pay their share now for us to recompose part of what was damaged. it's nature that needs money and financing. >> i'm joined by the bbc south america correspondent katie watson who is in the land where the conference is taking place. very strong words today from

president desilvia taking aim at the world's wealthiest countries. take us through what he said. >> i think he makes the point that a lot of people feel here, which is that the likes of the u.s. and europe like to say there are big problems here with the amazon and actually brazil needs to fix this, if you like. and what he's trying to do is say the amazons speak to the amazons. the region as a whole has got together. this has been a really important step and that there can be solutions that come from in liege region and that's not brazil's problem that it's a world problem. a message i think for many people here really resonates. a developed country that has prospered is now telling a lot of countries that programs are having problems because of climate change that they need to do something. this is a problem for the whole world.

as opposed to just a problem for brazil. >> the declaration that that agreement concerns the amazon fell short of the expectation, how big a disappointment is that? >> it was a big promise made during the campaign and once lula took power here a few months ago. zero des from station by 2013 was an objective they wanted to make. the president said yes, this was a consensus. we didn't have negotiation but brazil wants to power through on that. they want to bat defirst -- deforestation by 2013, not -- 2030, not necessarily zero deforest station. they have made big steps to

reduce it. deforestation down 66% compared to the same time in july of last year so they're moving in the right direction. >> so setting the stage for the conference in 2025 that will be back there. >> absolutely, the objective for him is to put the amazon on the map hosting a summit here in the amazon as opposed to somewhere like sal paulo oreo which is very far away. that was the objective he wa wanted. he's it's been in the spotlight. in two years' time far more people will be back here and once again talking about the amazon and the people living there. looking after them, they'll look after the planet too. >> katie watson in brazil, thank you. there's a new front in the tech war between two global powers as the biden administration is tightening restrictions on

certain american investments in chinese technology. it's doing so it says because china is one country that has exploited and can exploit, it says, american investments. the new order would prohibit some u.s. funding of sensitive technology in china. the order requires that the u.s. government be notified of other investments in chinese tech so why is president biden taking this action? well, the goal is to prevent u.s. money and knowledge from helping to develop certain technologies as much as those that could support the modernization of china's military and tech developments that could threaten u.s. national security. the biden administration said the order restricts u.s. investments in the following sectors -- semiconductors, quantum information technology and certain artificial intelligence systems. now in russia, officials say an explosion out of molls cow area factory on wednesday injured at least 56.

footage captured the moment of the explosion. officials did not say what caused the blast. but the explosion comes as alleged ukraine drones were intercepted on their way to moscow. our will vernon reports on the latest developments. reporter: just a few months ago the very idea that the usual aren capital could be hit by drone attacks or explosions was almost unthinkable but now it's becoming almost a daily -- occurrence here the russian defense mini city industry said that two ukrainian drones had been shot down by russian air defenses in the moscow region. they said there were no casualties or damage. we heard from the mayor's office who said that to combat drones had been brought down, one of those in the area of the city where there's an international

airport and russia social media channels posted video which showed explosions lighting up the night sky. you might be thinking this is all sounding rather familiar. position cow has been hit by a whole string of drone attacks in recent weeks. we all saw that video of skyscrapers in the moscow business district being hit by drones. that explosion. quite shocking for residents to see in the center of moscow. it's worth mentioning that these incidents are really incomparable to the depth and destruction brought to ukrainian cities by russian forces. on monday, russian missiles hit the eastern ukrainian city of pokrovsk and today it was confirmed that the official death toll from that incident has reached nine people. >> turning to the ongoing

migrant crisis in europe and yeted a tragedy. some 41 migrants died in last week's shipwreck off the italian island. the only four to survive the disaster told rescuers that their boat has set off and sank within hours after aparting. the survivors reached land on wednesday. the ruth is a major pathway into europe for asylum seekers and other migrants and israel's interior ministry reports it has seen nearly 750 arrivals by sea so far this year. our reporter has the latest. reporter: this is another tragedy in the mediterranean sea. there were only four survivors, 20's and a 13-year-old boy. they told rescuers that they were on a boat that are carrying 45 people, including three children. they described it as a very small metal boat, about seven

meters long. they said that only after a few hours at sea, the boat capsized and sank, apparent because of a big wave that threw everybody onboard into the water. the survivors said that only 15 people were wearing life jackets and according to the red cross, they survived by language on to life jackets and other inplatable devices. they then found another empty boat at sea and they got onto that boat and managed to survive for several days without food or water. they were finally rescued by a cargo him and brought to lampadusa on wednesday. migrant arrivals in italy have gone up. this year nearly 94,000 have reached italy so far by sea. this is by far the most dangerous migrant crossing in the world and that's because,

according to the u.n., since 2014, more than 17,000 people died or disappeared in the central mediterranean trying to get to europe in search for a better life. >> the world bank is cutting off any new funding to uganda because of the country's tough anti-gay law. the east african country enacted the bill earlier this year. the financial institution says the law is not in line with its values and was highly concerned about its adoption in the country. ugandan officials called it unjust and hypocritical. homosexual acts were already illegal but the new act can lead to death in some cases. yemen, the poor i guess so country in the -- poorest

country in the arab world has been brought to the edge of collapse by the civil war. the coalition supported by britain and america intervened but the europe he'll still shovels most of the north. our senior international correspondent spent several days in the city's main hospital. >> every second counts. and war has taught them to be quick. it has honed their skills. at this hospital, doctors patch up some of the latest broken bodies. this time it's government troops hit by a drone. one soldier called omar could not be saved.

another is rushed away for treatment elsewhere. anyone can be a target here. not just men in uniform. nearby, we meet hanati. every painful step reminds her of the war. her father struggles to pay for her treatment. she was shot in the back by a sniper, he tells us. that was in 2016 and the bullet is still lodged inside her. are you very worried about the future for hanati? >> yes, he says, i am worried about her because she's a girl. i wish it happened to me and not her. i wish the sniper had shot me and not her. >> this is the biggest hospital in a city that has been a battle ground for years.

these days it's not all-out war but it's not peace either. the guns are quieter but this hospital is still receiving plenty of patients wounded by the conflict. like muhammad, who is 7 and crying for his mother. his dressing needs to be changed. it's hard for his father, alwan, to watch. muhammad lost three fingers when he picked up an explosive device. he was playing on the roof of his home. >> he's scared because his hand is gone. he's very scared. he can't do anything. he can't even hold a pen. >> in the hospital's busy prosthetics clinic, they try to replace what war has taken away but these artificial limbs are

basic and it's traumatic, even for the doctors. it must be very, very hard for you to see the children like this. >> it's so bad. >> it's very upsetting. our hearts ache when we see yuck children who are still looking forward to living and enjoying life. needing amputations. >> next door, a regular physio therapy session for shala, who has been walking this path for years. a land mine took her leg and killed her friend. she is determined to be a lawyer and at 12 years old, she is the voice of a generation in yemen. >> children here suffer. they've lost their arms and legs.

they won't go out and play like other children around the world. they play in comfort but they play in fear. we just stand by the doors of our homes. when we hear shelling or gunfire, we run back inside. >> what would you like to say to the international community, to the world about what is happening here in yemen? >> why don't you see the children of theis? why all this neglect? are we not humans in your eyes? >> across town, an honor guard for omar, the soldier killed in the hussi drone strike. one more depth in a long war and few here see a chance for peace. "bbc news."

>> to some other news. heavy rains on wednesday caused a norwegian dam to partially collapse, sending water gushing and causing widespread floods. rivers reached their banks. and a power plants along norway's longest river ended up flooded. pakistan's president resolved to the parliament. the disillusion allows an interim government which is yet to be established to oversea -- oversee the next gen election by november. the former president was sent to prison and barred from politics for five years. a u.s. nurse and her child were safely released after their kidnapping in haiti. she and her child were kidnapped nearly two weeks ago. the u.s. state department become welcomed the report of the pair's release. the eldest member of the u.s.

senate, california lawmaker dianne feinstein was taken to hospital on tuesday after what her offers described as a minor fall. she's since been released from hospital and is recovering at home. it's the latest health-related incident for the 90-year-old senator. before we go, it's something we've all heard for years, that goal of 10,000 steps per day as the ideal number to stay healthy and fit. but a new study shows that as few as 5,000 steps may be enough to show a benefit. a study showed that 4,000 steps a day helped to reduce the risks of dying prematurely of any cause and if you can't manage that. one study said just 2300 were enough to benefit the heart and blood vessels. thank you for watching. take care. ♪
