this is bbc news. the headlines: india has now registered 4 million cases of coronavirus, with figures reaching record levels almost every day. among the world's most affected countries, the number of new infections is growing fastest in india by some margin. india is currently recording almost 82,000 new cases per day. people in lebanon have observed a minute's silence a month after a massive explosion in beirut killed almost 200 people and left 300,000 homeless. rescuers are continuing to search in the rubble for possible survivors after some signs of life were heard on thursday. there's been condemnation of the appointment of the former australian prime minister, tony abbott, as an advisor to the new uk board of trade. he has previously been accused of homophobia and misogyny. downing street said that he negotiated a number of trade agreements while pm.

it's been a confusing day for british tourists, struggling to work out whether they will need to quarantine themselves when they get back from holiday. from today, scotland, wales, england and northern ireland are imposing different quarantine periods for travellers who arrive from portugal and greece. 0ur europe ccrrespondent gavin lee reports from southern portugal. back to britain from faro airport this morning. where you're going back to now dictates whether you have to self—isolate. there's been no clarity from the government as to what we were doing. karen and mick are heading to birmingham. they don't need to quarantine, but they bought early tickets home because they thought they did. obviously not very happy. we feel as though we've lost two days of our holiday. it's cost us an arm and a leg and... we're just very disappointed. as more and more british tourists return home,

it's clear to me how confusing many people find the new rules. for example, if you're an english traveller flying to cardiff today, you can then drive back, won't have to self—isolate. but if you're welsh and, say, land at birmingham today, you'll then go back and have to spend the next two weeks in isolation. and this new way of travelling has just become even more complicated. so just how do the uk nations differ on quarantine? if you live in scotland and are returning from portugal or greece, you have to self—isolate for 14 days. for portugal, that will kick in at 4am tomorrow. if you're arriving back in wales from portugal, self—isolation started today. but from greece, the welsh government only requires you to quarantine if you're coming from specific islands. in england and northern ireland, there are no restrictions. portugal has seen a rise in coronavirus cases in recent days, going just above the uk's margin of safety of 20 cases per 100,000 people. but the tourist destinations of

the algarve aren't the problem. so why are politicians taking such different approaches? we look at the data, and then we do speak, but i'm afraid quite often coming to slightly different outcomes. hugs and relief at glasgow airport this afternoon as travellers made it back before their isolation deadline. but few are smiling about the decision here. we had to change our flight. we were just disappointed that scotland obviously had to quarantine but england don't. it was a risk. we knew that we were making a risk anyway, so we only lost a day. it is annoying, but i'm just glad we made it home in time. it's estimated that more than 30,000 uk holiday—makers have headed out here since the travel corridor opened two weeks ago. golf and good weather — a magnet for older travellers, for so—called ‘silver season'. 0n the streets of faro, the usual rhythm of the night is quieter. the attraction of a late summer break here may have lost some of its allure. with fewer british arrivals today, the risks and unpredictability of travelling

to these shores is perhaps too much of a gamble. now on bbc news, 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, 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.

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 organization 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 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 another farm 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 there. it's going to feel rather cool this weekend, certainly for the time of year, and that's because of where our we and that's because of where our have low pressure north—east we have low pressure to the north—east of the uk, high—pressure to the south—west, this is why we got a run of cool north—westerly winds that feed showers into northern and western areas. into the afternoon we could see an area of more cloud and longer spells of rain pushing to north—west england and north wales, there will be showers running through the chester gap into the midlands. best of the sunshine in the south—east, 18 degrees here, otherwise, mid—teens over the north and west. through saturday night this feature will spread across the irish sea, bringing patchy rain stop if you itemise on the charts for sunday so lighter winds but it looks like most of

the showers on sunday will be across england and wales, the heavier one around. view of the showers for northern wales, sunshine here, and because the winds will be lighter, it might feel a touch warmer on sunday afternoon.
