the headlines: more than 2.5 million people have tested positive for covid—19 in the us. some of the worst affected states are reimposing restrictions they had lifted. they include florida and texas. some business owners say it is a devastating blow. malawi's newly elected president, lazarus chakwera, says his victory is a win for democracy and justice. the election result is being seen as a democratic first in sub—saharan africa. last year's flawed election was overturned, with the opposition going on to win power. here in the uk, the government is to ease travel restrictions, meaning arrivals from certain european countries will no longer have to self—isolate. the 14—day quarantine will be scrapped for passengers coming from places including spain, france and greece. the new rules apply from 6july. a resident at a glasgow hotel where six people were stabbed on friday says the man who carried

out the attack had warned he planned to hurt people. the 28—year—old, who was shot dead by police, has been named as badreddin abadlla adam, who was from sudan and believed to have been an asylum seeker. alexandra mackenzie reports. the cordon remains in place around the park inn hotel, a grim reminder of yesterday's multiple stabbing. armed police arrived within minutes, shooting dead the attacker. he was 28—year—old badreddin abedlla adam, from sudan, who was living in the hotel during the coronavirus lockdown. suraj, who was also living there, said the attacker warned him that he wanted to hurt people. to be honest with you, before he did that, he said that to me. he said, "i will attack." i thought that he was joking. i said, "no, it's fine, you don't need..."

he said, "i hate them, they hate me." and that night, i complained to the hotel reception. and the man in the reception, he said, "i will take it seriously," and he make the complaint. completely, i didn't imagine that he will attack on the next day. others described him as quiet, and said he struggled with life in the hotel. i was so surprised, because to me, i didn't know that that guy — because he was so quiet, i didn't know that he was able to snap. constable david whyte, one of the six people who were stabbed, said in a statement: two members of staff at the park inn hotel and three asylum seekers who were staying there were also stabbed. they are all being treated in hospital. scotland's first minister said:

the scottish refugee council said they have expressed concern about the use of hotels for people in the asylum system. the home office said tonight that, throughout the pandemic, they have prioritised providing asylum seekers with somewhere free and safe to live. alexandra mackenzie, bbc news, glasgow. now it's time for our world. in december last year, locusts started swarming across east africa. now, hundreds of billions of these tiny creatures have invaded the region from somalia to uganda.

it's the worst locust outbreak that kenya has seen in 70 years... ..threatening to destroy the livelihoods of millions. if nothing is done, each generation of locusts multiplies by 20, so the race is on to stop them breeding again. i'm anne soy, the bbc‘s senior africa correspondent, and i've spent the past few months stuck in nairobi, covering the impact of the covid—i9 pandemic.

today, i'm leaving the city to find out about another crisis which has the potential to be even more destructive than covid—i9 for some areas of my country. nairobi is one of the hotspot areas for covid—i9, and so movement in and out of the metropolitan area is forbidden, except for essential services — that includes journalists like us — but we still had to get this letter from the media council of kenya, just to certify that we are allowed to travel outside the metropolitan area. and we also have our press cards, to show the security officers who are making sure that there's no movement in and out of that area. we are travelling to northern kenya, where they reported a swarm of locusts almost the size of moscow at the beginning of the year.

albert lemasulani's family have lived on this land for generations. they are samburu nomadic herders, who rely almost entirely on their animals. taking care of their livestock is not only their way of life, but crucial for their survival. but these vast swarms of desert locusts threaten the vegetation they rely on to feed their animals.

albert took an extraordinary decision. he has spent the last five months and much of his personal savings tracking the locust swarms and sending coordinates to the teams working to prevent a plague. now they call him ‘the locust man'. the original migrant locust swarms came to kenya from the southern arabian peninsula.

extreme weather conditions there allowed at least three generations of locusts to breed undetected. despite international efforts, months later, a new generation of kenyan—born locusts hatched. now it's a race against time to stop them breeding another larger and more destructive generation. it's early morning and albert is with a government surveillance team tracking the latest swarm. swarms of desert locusts can contain tens of billions of individuals and travel up to 150

kilometres a day. they need to pinpoint the current swarms so the spray planes can cover the area with pesticides. they've found the swarm. albert's firstjob is to enter all the information in an app designed specifically for people to input data and track the swarms.

a member of the grasshopper family, these normally shy, solitary insects become gregarious mini—beasts when vegetation starts to dry up and they are crowded together. each locust can eat its own body weight daily. even just an average swarm can destroy crops sufficient to feed 2,500 people for a year injust a day. hello! the team has called in their location to the spray planes. but if it doesn't get here soon, the locusts will start moving again.

it looks like time is running out to tackle this swarm. ..trying to spot where they can be able to... they didn't manage to spray the swarm in time. albert now relies on motorbike scouts to do much of the ground tracking. it's all rough roads here, and hard to access.

when he started out, albert was doing this work alone. but with the support of an international ngo, he's trained a group of young men who shared the geo coordinates and information on the swarms on the app tracking desert locusts, so now, they know where to spray. albert has asked one of his spotters to go and check a site that was sprayed last month.

luckily, it appears to have been a success. that swarm was destroyed. it's a new day and albert has found the biggest swarm he's ever come across. all across north of kenya, trees that look burnt but when you get closer, you realise they're just full of locusts. when locusts hatch, they first form hopper bands, a stage where they are unable to fly, that lasts about six weeks.

then, they turn pink in colour, start flying and form swarms. when they mature, they turn yellow and they are ready to lay eggs. the whole process takes about three months. this is what albert fears most — this swarm is almost ready to breed. an average female lays 150 eggs in her lifetime.

if a second kenyan generation hatches, it could be devastating. so, captain... yes. this is captain neepe. he flies one of the surveillance helicopters for the un food and agriculture organization.

as we are filming, they get more bad news. heavy rain means the spray planes further south cannot take off. this enormous swarm of mature locusts is able to fly again and they are one day closer to breeding the next generation. albert is going home to see his family for the first time in two weeks. but the threat of covid—i9 means family reunions are difficult.

albert has not spent more than one week at home since his youngest son was born. albert's wife angeline is looking after their four children and albert's ioi—year—old grandmother. despite the sacrifice,

albert is determined to help his people. it is dawn in lewa conservancy, in laikipia, northern kenya. this is one of the operation‘s bases for tackling the locusts. the un food and agriculture 0rganization works with the kenyan government to manage aerial and ground spraying. but kenya only has five spray planes, and it's one of the most equipped countries in

the region battling locusts. this is the only way the locust swarms can be controlled, using these pesticides. kenya has stockpiled them but because of the covid—i9 pandemic, the global supply chains have been disrupted and that means it's becoming increasingly difficult to import more chemicals, and that's the big fear now. with chemicals scarce, it's crucial that they are accurate where they spray. and it's albert and the surveillance team's job to get the information to the pilots.

today, spraying has been a success. but to stop the devastation, they need to destroy the majority today, spraying has been a success. but to stop the devastation, they need to destroy the majority of the swarms before

they breed a new generation. over the next two weeks, albert keeps tracking the swarms as they travel north. he sent us his reports. when they are mature, the locusts dig holes to lay eggs in the earth. they are hard to spot and even harder to destroy. then, the moment they had all been dreading — the next generation hatching. enormous hopper bands are discovered all across the desert areas of marsabit, northern samburu and into turkana.

we join albert again and travel north to the county of turkana. it's the end of the rainy season here and the crops are almost ready to harvest.

it doesn't take long. 0ur drive up to turkana is interrupted by a massive band of hoppers crossing the road, taking over everything they can. rebecca and her eight children grow maize and beans on their farm, just a few kilometres from the border with uganda. heavy rains meant they were expecting a good crop. they are trying everything to defend theirfarm from invading hopper bands.

the only hope now for rebecca is that pesticides will work, if they get here in time. while we were with rebecca, we heard of anotherfarm in turkana that had already been taken over by hopper bands.

albert and the teams are fighting as hard as they can to prevent a plague of locusts

through the region. but with this generation likely to be the biggest of all, the future looks very uncertain for millions. hello. well, the fresh weather is here to stay for the foreseeable future, at least the next week or so. so, plenty of showers in the forecast, and on top of that, it's also going to be windy, particularly on sunday. really quite blustery for the time of the year. now, the reason for it is this low pressure that swung out of the atlantic is being propelled by a jet stream. that jet stream has also introduced that much fresher air,

and it's here to stay. this is what it looks like through the early hours. so, the possibility of catching showers almost anywhere through the early hours, but more especially, i think, across the north—west of the uk and really across parts of northern ireland, the north—west of england, and the south—western as well as western scotland. it could be really quite wet during the course of sunday. you can see these weather fronts spiralling into the area of low pressure, and around it, we've also got those strong winds circling. you can see those winds circling about scotland. this low pressure is also quite slow—moving, which means that this weather is just going to carry on for the next 48 hours or so at least. and you can see where the heaviest the rain but those winds will be strong. gusting in excess of a0 mph in places. that's near gale force — a real bluster out there. let's have a look at the weather

around 4pm in the afternoon. so, actually not looking bad at all for the south, the london area, east anglia and much of the midlands, and then we get into wales and further towards the north and west, you can see the pulses of heavy rain. now in scotland, it looks as though these more eastern areas will probably be a little bit drier and brighter. so, let's have a look at the forecast, then, as we go through the course of monday. the low pressure is still very much with us. you can see heavy rain affecting parts of northern britain once again, but to the south, so the further you are away from that area of low pressure, you can see it's drier and brighter with temperatures getting up to around about 19 degrees celsius. so not even making 20 early in the week. now, the temperatures will probably creep up a little bit into the low 20s through the course of the week, but plenty of showers, i think, on the cards across more northern parts of the uk. so, as i say, the fresh weather is here to stay.
