the region — which you can see here in red — is officially part of azerbaijan but it's been controlled by ethnic armenians since the collapse of the soviet union. in azerbaijan's second city, ganja, which is outside the region, at least seven civilians in a residential area have been killed by rocket fire. in nagorno—karabakh, damage to the main city, stepa na kert, continues, with air—raid sirens sounding. this video is running on armenian state media. our international correspondent orla guerin sent this report from azerbaijan. "let me see his face," she begs. "one last time." she is not alone in this desperate search. "let me see," says this woman. "is he from my family?"

"may the armenians die", she cries. this is what's left of her neighbourhood in ganja, azerbaijan's second largest city. far from the front line, but not far enough. at the scene, remnants of what baku says was a ballistic missile. it is accusing armenia of a war crime. this was clearly a civilian target, apartment blocks, flats, where people were living. there is bedding and blankets and mattresses strewn among the rubble here. the attack happened at about 2am. now, this is supposed to be a ceasefire, but it looks more like all—out war. and what happens next? is there worse to come on both sides?

standing here now, in the rubble, is the ceasefire dead? actually, it's hard to assess the situation. therefore, currently we are considering the situation. if armenia continues to attack azerbaijani civilians, then azerbaijan will be obliged to take necessary measures against legitimate military targets. you are saying that they have fired at you, and you are also saying that you reserve the right to retaliate. so, which is it, are you sticking to the ceasefire or are you going to retaliate for this attack? at this stage we are trying to stick to the ceasefire regime, but of course, if they continue to do so, attacking azerbaijani civilians, as every nation, we also have a right to self defence. we were shown the destruction here in ganja, but azerbaijan too is accused of breaching the ceasefire by shelling civilian areas in nagorno—karabakh. "we are all mothers," this woman told me. "there and here —

and our hearts are aching." armen is a armenian american surgeon. he travelled from los angeles to nagorno—karabakh to work in a hospital and criticised political leaders on both sides. it political leaders on both sides. doesn't matter if y( medical, it doesn't matter if you're a medical, politician, engineer or a pilots, no—one wants to have to have war or have kids die. it takes one relative of yours to use lie or a limit for you to stop thinking about it. people have read power, they don't send kids to war, the sensibly else‘s kids to war. they don't care how many families are involved in this tragedy, they simply want to prove their point. if the presidents of these countries who are starting the war, if they send kids to the

front line, then i would understand what everyone else will go to war too. on to the latest on coronavirus, and here in the uk, the bbc understands that the liverpool city region is expected to be the first part of the uk to be put under the tightest coronavirus restrictions, under a new three—tier system for england to be announced by the prime minister tomorrow. with extra measures expected to apply to the north of england, the government has been under pressure from local leaders, and from some mps, to give them more detail on its plans and to offer more financial support to business and individuals who'll be affected. on the loudest, liveliest streets, people worry about what's to come. and they want to be listened to, to be understood. all the things that are getting cancelled, the things we enjoy this time of year — halloween, bonfire night, christmas — these are the things that we are going to have to compromise with. if he'd have done it earlier, i think we wouldn't have got this far. the only way you're going to do it is total lockdown. once you've got total lockdown, you've got it under control.

we were doing really well before... ..all of this happened. but listen to conor — running a pub already quietened by local restrictions. we're not even breaking even at the minute, never mind being able to pull back all the rent that we still owe or pay back the wages that we topped up, and further restrictions will just. .. it could be a final nail in a lot of people's coffins, unfortunately. i would say our sales are down 50%. and jonathan is wondering whether restaurants will be hit by new tiers of rules. you know, liverpool has known tough years. i've been here when it's been tough, but, you know, over the last 10—15 years, it's been a brilliant place to be and it worries me that rug could be pulled. consider too the challenge of enforcing even tougher restrictions that have so far been rumoured, floated, leaked, but still not confirmed. i haven't felt anger like this towards the government since i was growing up

here in the 1980s. people feel that they haven't just been abandoned by the government, they now feel that the government is actively working against us. it wasn't just liverpool busy at ten o'clock. look at london's leicester square. and in peckham, they were playing cricket. the government denies it is unfairly targeting northern cities. you say that there is anger in the north. there is. but the measures we are bringing in here are universal. these apply across the whole of the united kingdom, and there is nothing that we would ever do that penalises one part of the country over another. after the curfew came in, it was just game over. but think aboutjoe, still paying for the taxi that no longer covers his bills. have toxic you don't know where you're going to be in four weeks' time. am i going to be driving a taxi, or going to be working in a factory or living on the dole with no money?

these are delicate decisions, but in this city and others, people wonder how much they are about to be silenced. our political correspondent chris mason says the situation is still evolving. occasionally come up little correspondence may sit here on a sunday night and give the indication that everything is moving when actually it will start again tomorrow morning. this evening, it really is happening now, the negotiations are ongoing between civil servants in regions of the north of england and their cou nterpa rts north of england and their counterparts in whitehall. there is also been political conversations as well between mayors and council leaders and ministers and senior representatives in the government. what we're going to get tomorrow from the prime minister is the setting out of these tiers that have been widely trialled over the last three weeks that will classify england into three different tiers. however, what's important to stress is tomorrow as the start of this

process , is tomorrow as the start of this process, not the end, so i don't think we will get a map like the one thatjeremy vine strike surrounds on election night where england turns to three different colours that might happen eventually but not straightaway, because negotiations and discussions between local leaders and government take time and are not ready to be signed off yet. president trump has claimed it looks like he's now immune to coronavirus. here's what he told fox news earlier today. it seems like i'm immune. so, i can go way out of a basement, which i would have done anyway, and which i did, because you have to run a country, you have to get out of the basement, and it looks like i'm immune for maybe a long time or maybe a short time, it could be a lifetime, nobody really knows, but i'm immune. so, the president is in very good shape. mr trump's comments come a few hours after his personal physician released a letter saying the president is no longer considered

a transmission risk to others. let's speak to susan butler—wu, a microbiologist and associate professor of clinical pathology at the university of southern california. good to speak to you and i do want to bring up the doctor's letter, but first, i would like to ask you what you hear when the president to say is, i'm immune. i don't think the president is any proof he's immune. the bottom line is, the president was given a cocktail of antibodies which themselves, depending on whatever test was used, could actually cause false positive is. so without knowing what test was used, we can't conclude he has antibodies present that he made himself. furthermore, the presence of antibodies does not correlate immunity and it is important to say, evenif immunity and it is important to say, even if you have antibodies detected, you should not conduct yourself any differently. let's look in more detail at this latest memo

from mr tom's doctor. it says the present rack is no longer considered at risk of transmission to others. does that mean it is safe to be around him? i don't think that is how i would interpret what has been put in place. i think the cdc uses criteria for deciding that someone is no longer infectious and that would be something to discuss with an infectious disease physician, but the number of days where the bare minimum, we know they president was given cortisone steroids which prolong the shedding of the paris. i don't think we can conclude that without knowing what sample was tested. we know patients have actively replicating virus in their sputum that can be present when negative in nasal specimens, so we need more information to conclude that, and an infectious disease physician to actually know the information. the radiographic findings were never released, we don't know what the ct values are

and they currently recognise standards—based and diagnostic testing is incorrect, there aren't any at the moment. make you feel better if we at another part of the memo which says there is no longer evidence of actively replicating virus. i'm lost, is that the same as a negative test? there are several different test for covid. what they referring to here, because they are not providing the specific information about what the advanced diagnostic tests are, but pcr, the standard covid test you would get if you are symptomatic, you can be positive for that for some time after you are infectious, so i think that's why they pursued a different testing, which is a research protocol not available any clinical diagnostic lab in the us. it is among the replication of the virus, so among the replication of the virus, so the problem is, without knowing what specimen was tested, without knowing what lab it was done in awe

of the protocol, we can't conclude that. the other typical wayward with the cell culture, but there is been issues with that in some controversy. is a reading between the lines, i would infer he is probably still testing positive by pcr and ten days is the bare minimum with the cdc for patients with coronavirus and it should be longer. i think coronavirus and it should be longer. ithink an coronavirus and it should be longer. i think an infectious disease physician we need to look at that data to make the call, it is concerning. thank you. now for a full round—up from the bbc sport centre. good evening. lewis hamilton has equalled michael schumacher‘s all—time record of 91 formula i victories. the championship leader won an action—packed eifel grand prix at the nurburgring, overtaking his mercedes team—mate team—mate valetrri bottas, who then had to retire. hamilton's championship lead over bottas is now 69 points meaning he's within just a couple of races of matching schumacher‘s

seven world titles. i don't think anyone, especially me, imagined i would be anywhere near michael in terms of records, so it's an incredible honour and it's going to take some time to get used to it. honestly, as i came into the pit lane, that's only when i realised i'd equalled it. i hadn't even computed it once i crossed the line. meanwhile, there was tennis history in paris today as rafael nadal equalled roger federer‘s record of 20 grand slam men's singles titles. he beat the top seed novak djokovic in straight sets to win the french open for a 13th time.
