on the island of mykonos. hello and welcome if you're watching in the uk or around the world 7 and stay with us for the latest news and analysis from here and across the globe. supporters of the russian opposition leader, alexei navalny, have described his condition as very worrying. the longstanding critic of president putin is receiving hospital treatment in berlin. he was flown to germany after suspected poisoning in russia. but moscow has denied targeting him. our correspondent in berlin, jenny hill, has the details. oblivious to the political storm around him, alexei navalny, arriving in berlin for treatment. the man who took on vladimir putin is in a coma. he collapsed on thursday during a flight over siberia after drinking what his supporters claim was a poisoned cup of tea.

i'm sure that they can treat him and do everything to eliminate maybe this toxic agent from his body, i hope that the germans, with a high level of medicine... we have no such opportunities in russia as german doctors have. mr navalny is one of vladimir putin's fiercest critics, an anti—corruption campaigner with powerful enemies. his supporters claim he was poisoned last year but lived to tell the tale. now they believe the russian authorities have tried to silence him again. that is something the kremlin denies. it was a german ngo which organised mr navalny‘s transfer to berlin, though it is believed western political intervention finally persuaded russia to let him go. he is a healthy, strong man with a good constitution. the night before the attack, whatever you want to call it, he was swimming in a river,

and there is this media we have all seen from the plane where he gets this incredible pain and is screaming. doctors here say it will take time to examine mr navalny. it may now be too late to establish whether he was poisoned and harder still to discover by whom. it's not the first time an opponent of vladimir putin has come to berlin with suspected poisoning. two years ago, a dissident was treated in the very same hospital. this could be the latest in what some here say is an increasingly provocative pattern of behaviour. tonight, as a man fights for his life, that is putting pressure on what is already a tense relationship between russia and the west. no statement yet from the german hospital on whether mr navalny was poisoned or not. let's speak professor alastair hay, a toxicology expert from the school of medicine at the

university of leeds. it is very good to have you with us, professor hay. first of all, how will the german medical team establish whether alexei navalny was poisoned or not? they will be taking blood and you're in samples from him and subjecting them to be the most wide—ranging screening process possible. —— you're in samples samples. they will be looking for families of chemicals and if they identify any of these they will do more specific tests. it is long process when you don't really know what they're looking for. it is better for them to identify a chemical if they can because this can then lead to more specific treatment. they have been some

questions over how and whether i should say a toxic substance will still be detectable. yes, i think if it was something that was highly toxic there is a good chance of still finding it but of course it varies hugely according to the individual substance. some are present for a very short period and some have really quite extended stays in the body, so they will be doing as much as they can to try and identify something. they still have a good chance and particularly if they were able to get any blood or urine samples from him that were taken soon after he was admitted to hospital. a lot of focus now is a mess navalny‘s tell. how might doctors in germany be treating such a poisonous substance in his body? -- is a poisonous substance in his body? —— is on mr navalny‘s health. a poisonous substance in his body? —— is on mr navalny's healthlj think it really would want to be in

an intensive care unit and that is where he is. it is about maintaining life so all the services that you get in intensive care, additional respiratory support, checking and maintaining his blood electrolytes, keeping track of his fluid status, checking sugar levels, the whole works really, and function of the hearts to maintain life, and then once they can identify aces specific substance if they are able to do that then that can lead to more direct treatment, more specific treatment for an agent. now, direct treatment, more specific treatment foran agent. now, russia is denying any accusations that have been out there that they are behind this poisoning. russia has used or been accused of using various toxic su bsta nces been accused of using various toxic substances in the past, polonium and of course another chalk which was in the salisbury poisoning. —— novichok. are there other particular su bsta nces

novichok. are there other particular substances that you might be looking for is agency may have used. for is agency may have the substances that you might be looking for is agency may have the doctors treating mr navalny will have tried to focus on what signs and symptoms he might have been displaying at the time and this will lead them to focus a bit more intensely on a particular range of substances. at this stage it is really quite difficult and i imagine that they probably have an open mind but they will be screening for a wide range of things, as i said. this is generally the approach. you look for families of chemicals and then if you find that family you can then focus on more specifically on a particular substance to identify it. they will be looking at the science, obviously, he is displaying at the moment, and trying to from there. just make the signs he is displaying. we will have to leave it there, professor, but thank you very much for your insight. three countries have been added to the quarantine list in the uk. anyone arriving from croatia, austria, and trinidad and tobago now

has to isolate for 14 days. in scotland, the measures also apply to arrivals from switzerland. many people on holiday in these countries, which have seen a spike in coronavirus cases, tried to change their flights after weeks of uncertainty and changes to quarantine rules in popular tourist destinations, flying out of gatwick airport this evening, there is relief. these holiday—makers finally have somewhere to go, portugal. we initially wanted to go to spain, then we rebooked for croatia because spain went into lockdown. then croatia got put into quarantine yesterday so we quickly switched to portugal. we had to pay quite a lot extra. on thursday night, it happened really quickly, so the flights were

booking up really fast were started off relatively low level prices and, by thursday evening, they had skyrocketed about £1000 for a villa of ten. the minute the quarantine was lifted, that was it. we booked that day. we did. within about two hours. for those who had already taken the chance and headed to towns in croatia, as they return, they now face 14 days in quarantine. after france and now croatia, no holiday can be guaranteed as being safe and, if you go outside the uk this summer, or this year, even, you can expect something like this to happen. most of the flights are on saturday morning. if they'd given 48 hours, we'd all be back, but now we all have to quarantine for two weeks, so it's a pain. some haven't yet made it back from the country. it shouldn't be 14 days. we should probably stay at home for seven to ten days and then get tested. if you are not positive, let us back to work and kids to school. this way, we feel

like it's a punishment. despite packed beaches in croatia, it's the spike in coronavirus cases which led to the restrictions there as well as in austria and trinidad and tobago. many will now question, is this worth it? or should they risk the british weather instead? frankie mccamley, bbc news. the world health organization has recommended that children aged 12 or over should wear face masks under the same conditions of adults. the guidance applies in areas where there is high transmission of covid—i9, and where social distancing cannot be maintained. the number of people who have died from covid—i9 around the world has now risen to more than 800,000. our correspondent imogen foulkes sent this update... this latest advice from the world health organization comes just to schools around the world, especially here in europe, about to reopen after full some here in europe, about to reopen afterfull some of them here in europe, about to reopen after full some of them anyway, months and months of closure, and

what the who says is that children over the age of 12 should be following the same kind of mask etiquette as adults. that means if distance can't be maintained in places like public transport, in shops, and of course in classrooms, they should be wearing masks. children aged six to 12 should also wear them under certain circumstances, for example very crowded areas, when they are in contact with vulnerable groups, that could be the elderly like their grandparents, but those younger children shouldn't wear them without aduu children shouldn't wear them without adult supervision. under the age of six, the who says no, they should not wear them at all. but the who says this is not a substitute for the rest of the stuff. hand hygiene, keeping your distance wherever possible, and really, really being aware over time that you're doing your to protect yourself and protect

others. the governor of california has appealed for assistance from canada and australia, as hundreds of wildfires continue to spread in searing summer heat gavin newsom said the two dozen biggest blazes were stretching resources, despite the deployment of twelve— thousand firefighters. other us states are sending fire trucks and planes to help. more than a hundred thousand people have been evacuated. we can speak now to our north america correspondent, peter bowes. help from australia and canada to fight these fires, but what is the condition at the moment? the conditions are not good. it is still extremely hot all the way to california. the worst affected areas are in the north of the straight, east of palo alto in the san francisco bay area and then in wine country to the south of sacramento and the firefighters are fighting

really difficult conditions. it has been quite windy also and these fires by and large were started by lightning strikes. very unusual, happens about once every 20 years these dry lightning strikes, and the forecast, sadly, is far more of these lightning strikes in the next 24, 48 these lightning strikes in the next 2a, 48 hours, these lightning strikes in the next 24, 48 hours, so it is these lightning strikes in the next 24,48 hours, so it is going to be extremely difficult for at least the next week. if you have reported on wildfires in california for many, many years. how do these wildfires compare with previous ones? they compare with previous ones? they compare pretty badly. i don't really remember a year when we have had so many fat wildfires at the same time and of course every summer seems many fat wildfires at the same time and of course every summer seems to get and of course every summer seems to get slightly hotter, the conditions, the bushes tinder dry and it creates this kind of perfect storm scenario for these fires to spread very quickly, and bear in mind, it is still, really, right at the beginning of the fire season. later in the years when the winds get

stronger, the santa... wins coming from the east, they create different conditions as well so californians are conditions as well so californians a re really conditions as well so californians are really bracing for many months ahead of these difficult conditions. of course, all of this while the state is also grappling with coronavirus. peter boaz, thank you very much. the manchester united and england footballer, harry maguire, has been released from police custody, and has been cleared to fly home, after he appeared before a greek prosecutor. he was one of three men arrested thursday in connection with a disturbance at a bar on the greek island of mykonos. police allege the altercation led to several officers being assaulted. in a statement, manchester united said the 27—year—old has pleaded not guilty to all charges, and would not be commenting further whilst legal proceedings take place. anthee carassava is a journalist in athens. she has been following this for us and has this update. well, he was released from police custody and this after a very lengthy testimony that he provided

doctors, but often they are afraid to report to police because they are afraid of further contact with police, and that's's the fact, that the people are feeling contact with the people are feeling contact with the authorities and the police. you mentioned human rights groups there. have a doing anything to kind of increased international pressure and awareness around this? yes. what i know that the organisation called spring 96 and a... committee and other groups as well are working ha rd to other groups as well are working hard to document the tortures and they are collecting evidence for the international human rights cults and they also repulsing that, as broad as they can, to the international
