and, new research suggests so much ice has melted in antarctica since the mid nineties, it could fill the grand canyon. hello, we start with breaking news from washington. president trump has just returned to the press room at the white house after he was suddenly told to leave mid—way through a press conference. this is what happened. it looks like they are just about going to be topping records... excuse me? president trump has just confirmed that there was a shooting outside the white house. here's what the president had

to sayjust moments ago. so, thank you very much. sorry for that. there was a shooting outside of the white house and it seems to be very well under control. i would like to thank the secret service for doing their... always quick and very effective work, but there was an actual shooting and somebody‘s been taken to the hospital, i don't know the condition of the person. seems that the person was shot by secret service. let's get the latest from our north america correspondent, david willis. david, what more do we know? the secret service has confirmed what they call an officer involved shooting at the corner of 17th street and pennsylvania avenue. that is

the eisenhower executive building, which is next door to the white house. quite a dramatic scene where the president literally midsentence, when he was approached by a secret service officer and escorted from the podium. our reporter who was nearby quoted the secret service agent as saying, in his words, step outside, so, we are going to have to step outside. now, the president wasn't taken to the underground bunker that exists at the white house, as indeed he was briefly at the height of those quite violent demonstrations at lafayette park near the white house at the height of the black lives matter demonstrations copy he was taken to the oval office where he spent eight minutes, and then was told he could go back and resume the press conference which he did, a wide—ranging press conference lasting about an hour thereafter, but it is highly unusualfor thereafter, but it is highly unusual for this sort of thing to unfold right in front of the television cameras. this was a

televised press briefing and the president led away, as i said, midsentence from that briefing. just help us with the geography here, how close did all this come to the president and we know anything more the actual incident? it seems to have happened outside the walls of the white house, and according to the president himself, mike, this was a suspect who was shot by the secret service and taken to hospital. the president thought that the suspect was armed and he paid tribute to the vigilance of law enforcement, but fox news reporter who was quite nearby at the time reported hearing two shot in rapid succession. now, all we know from the secret service themselves as i've mentioned was that there was an officer involved shooting. it does appear, even though there is a large presence still of law enforcement in that area, that the incident now has been resolved. david, thank you very

much for that. more on that as soon as we have more that we can confirm. the entire lebanese government has stood down following last tuesday's catastrophic explosion in beirut. the prime minister said it was the result of endemic corruption which is "bigger than the state" itself. angry protests have continued at the government's handling of the crisis, as the country faces economic collapse and food shortages. our middle east correspondent, quentin sommerville is in beirut. some lebanese would joke that they can't tell the difference between when they have a government and when they don't have a government, the stated though absent people's lives out but protesters were celebrating tonight. they see this at the beginning of a long process stopping they want the speaker of the parliament to go and the president as well. my report contains images that some viewers may find disturbing. inch by inch, lebanon is falling apart. they knew their government was finished but still, they want more.

even among the tear gas, these protesters can almost smell the government's downfall but they've brought down governments before and there's been little change here. a reshuffling of the same old faces at the top isn't going to solve lebanon's crisis. when the end came, there were cheers. and riot police. the prime minister gave his resignation to the president but his government remains until a new one can be found. the state is out in force in a shattered capital, carrying guns, though, not brooms. the lebanese are famous for their determination, but people here are sick of being left to fend for themselves. nobody else but the youth is going to help here. as you see, you can see some people from the government here and theyjust

sit and do nothing. it's not fixing. we do a revolution, it doesn't help. we become more aggressive, it won't help either, so what else can we do other than clean at the moment? some bonds in beirut remain unbroken. this man lived in this beirut flat for 70 years. just two blocks from the port. he and his wife were here during the explosion. this is our kitchen. most of the doors and windows are gone. is it time to leave, i ask? no, no, no, no, no. i stay with the tent here. gemmayzeh is a tight neighbourhood. a dozen people died on this one corner, and everybody here knows exactly where their neighbours were when the blast hit. but some are in no position to help.

their wounds are too raw. romy zakhour lauret was in her car on the highway by the port. she and her husband filmed the fire before the explosion. when we arrived to the hospital, it was like a movie. i had more chance than others because i saw that people on the road, people lost their eyes. today, she's having plastic surgery. drjoe baroud is offering his services to the wounded for free. it's my god telling me that if you can at least offer some kind of your expertise to help the people because if i'm going to go and work on the streets in five months and see people with bad scars on theirface, i'm going to feel directly responsible for it. fireworks explode. and tonight, tear gas and fireworks as lebanon slips further into the void.

this disaster brought the lebanese people together but it's also tearing their country apart. the lebanese people want to live in a country where their life savings aren't wiped out bya life savings aren't wiped out by a financial and economic crisis, where theirjobs and education and healthcare doesn't depend on sectarian and political patronage stopping they want to live in a city where there is 24—hour power, clea n where there is 24—hour power, clean water, whether traffic lights whether rubbish gets collect it. none of that happens but most of all they wa nt a nswe rs happens but most of all they wa nt a nswers to happens but most of all they want answers to what happened here. who was responsible for this disaster. weight government after government ignored warnings saying it was a bad idea to keep many thousands of tons of high explosive chemicals right in the heart of the city's. but the heart of the city's. but the lebanese don't expect that they will get answers to those questions because they have no

faith in their institutions and they realise that change happens here very, very slowly. let's get some of the day's other news. police in chicago will limit access to the city's downtown area, after a night of violence and looting. there will also be a ‘heavy police presence' until further notice. videos from the weekend showed hundreds of people raiding stores and confronting police following an altercation involving a suspect with a gun. more than 100 people have been arrested. at least one person has died and a number of others were injured after an explosion in baltimore. three houses were virtually flattened, in what the city's fire deparment has called a major gas explosion. the local gas and electric company says the cause of the blast has not yet been determined, and has cut supplies to the area as a precaution. thousands of students have taken part in an anti—government demonstration in thailand. in the biggest protest so far they again called for the thai prime minister, prayut chan—o—cha to resign. he first seized power in a coup in 2014. more rallies are planned for

wednesday which is a national holiday in thailand. it's been one of latin america's success stories when it comes to dealing with covid—i9 but on monday cuba reported a record number of new cases, with a surge in the capital, havana. restaurants, bars and pools have been closed in the area once again, with public transport suspended and access to the beach banned. let's get the latest from our cuba correspondent, will grant who's in havana. what is going on? you are right in saying, mike, that it was the success story and in many ways it still is. cuba has com pletely ways it still is. cuba has completely gotten on top of the outbreak in many parts of the island. it is just havana that has seen quite an uptake but that up tech does include the highest number of deaths registered on a single day, just 93 cases and obviously 93 cases would be seen as a good victory for some of the countries around the world but

here it has created a situation where they have started clamping down in the capital again. as it clear why the surge has happened? because cuba has such an excellent reputation generally on healthcare, doesn't it? it does. a lot of the accusation is that people have been gathering. things began to be relaxed in the main city, then gatherings for either religious reasons or for parties and so on started happening. and to use a very typical word of the cuban government there was a lot of indiscipline in the city. people started to get relaxed and i think that is human nature to an extent however the consequences have absolutely been seen, we're talking about 88 deaths in total in cuba stopping the great fear among the authorities is that this starts getting out of control because the healthcare system here

simply wouldn't be able to cope. with got some problems with the connection but let's press ahead if we can stopping the worry must be of the surge spreads outside havana. cuba really needs to open up again soon if it can. it needs the tourism dollars, it needs the euros from tourists heading backin euros from tourists heading back in this direction. 2020 is going to be an economically disastrous year for the island, so if they can start began opening parts of a backup they wa nted opening parts of a backup they wanted to, the problem is of course they really need to get havana back up and running and thatis havana back up and running and that is going to take a while longer and require the residents of the capital city to lock back down again, really towards the end of the year, maybe towards christmas stopping there might be able to salvage something of the tourism year. let's leave it there for now, thank you very much. the actor antonio banderas says he's tested positive for covid—i9 and is in

quarantine in southern spain. writing on twitter, he said he was feeling relatively well, but a bit more tired than usual. he's the latest film star to announce they have coronavirus. tom hanks, his wife rita wilson as well as the bollywood stars amitabh bachchan and aishwarya rai bachchan and british actor idris elba have all had covid—i9. stay with us on bbc news, still to come: a race against time in mauritius, after a government warning that a run—a—ground cargo ship, is about to break apart. the big crowds became bigger as the time of the funeral approached. as the lines of fans became longer, the police prepared for a hugejob of crowd control.

a leading pro—democracy campaigner in hong kong, agnes chow, has become the latest figure detained under the new national security law. it follows the arrest earlier of the prominent activist and media tycoon, jimmy lai, who was detained over allegations of collusion with foreign powers. in total eleven people were arrested on monday. joining me now to discuss the situation is hong kong based writer and lawyer antony dapiran, who is the author of ‘city on fire: the fight for hong kong'. what do you make of the latest developments? well, this really is continuing, this ongoing crack down but most shocking of the events yesterday was this really direct attack on hong kong's three press with the arrest ofjimmy lai and a large police raid on the offices of his newspaper. and do you

expect the people to be held for some time or do you think this is in some way a warning to others? well, under the new national security law, suspects can be held without bail so it's highly likelyjimmy lai, agnes chow and the others arrested yesterday will be held without bail until their cases come to trial which could be some months away and i think there is no sign that this ongoing crackdown is going to stop, especially in the context of wider ongoing tensions with the us and china and hong kong right in the middle of that. and do you expect china just to press ahead with it testing the water in some way, seeing if there is meaningful international reaction? well, we really haven't seen any backing from china all, notwithstanding consistent strong international pressure on the issue of hong kong. every week seems to bring new moves by the international community including of course the most recent sanctions from the most recent sanctions from

the us but that does not seem to have dissuaded china at all with the latest arrests, the sign that this seems to be continuing. i don't think there is any sense they are going to back off. do we know anything about how the people arrested are being treated because the chinese authorities are pretty rough with people in tibet and xinjiang. we do expect that here in hong kong, people will be receiving treatment in accordance with international standards of human rights. they are being held by the hong kong police, we understand they have not been handed over to the mainland authorities or ta ken across the border but that possibility is therefore more serious cases but we expect they do have access to their lawyers and they are being treated in the appropriate way but it's unlikely they are going to be given bail or singled out anytime soon. further to the future, how do expected to develop. we know that several democracy activists have left the country, do you think many

people will or will a lot of people will or will a lot of people behave as so many do on mainland china, that they have political opinions and certainly not voicing. that certainly not voicing. that certainly would be a very sad future for hong kong. we really are in transition. people trying to understand what the para meters trying to understand what the parameters of the new environment are, many people will take that option to leave, others will stay and try to fight on, as bravejournalists did yesterday and today, continuing to live stream the parade on the police headquarters and putting out the addition today is that they will be testing the limits and seeing what they can make of life in the new hong kong. you talk about the new limits, the new national security law is very broad, isn't it? yes, indeed, it is very broadly drafted, deliberately so, to enable the authorities to target any person they fight to be an irritant and that indeed is what they've done so far for

jimmy lai and agnes chow and i'm sure we will see others to come as they make use of this tool in their toolbox. thank you. the government of mauritius has warned that a huge cargo ship which has been leaking oil after running aground two weeks ago is likely to break apart. the prime minister said his country should prepare for the worst. the japanese owned ship mv wakashio, began leaking oil on thursday after it ran aground at the end ofjuly. the government declared an environmental emergency at the end of last week, but has been criticised for acting too slowly. our africa correspondent, catherine byaruhanga has this report. it's a rush against time for crews trying to empty thousands of pounds of fuel from the mv wakashio. days of bad weather are making their job wakashio. days of bad weather are making theirjob harder. even though some of the oil has been removed, 2500 times remain. mauritius's my minister

is warning it could split, sending it all into the indian ocean. translation: we know that there are similar quirks which are continuing to develop and these quirks unfortunately mean that there is a major risk that the carrier will split into two. closer to land, the clear to see. i think, toxic sludge of fuel, seeping from the ship, is invading endangered coral, wetlands and lagoons. the clean—up efforts here rely on volunteers. some are making these home—made booms filled with sugarcane stalks, tights, and even how to soak up the oil. these voters are everything to motions, a source of its lucrative tourism sector, a provider of food.

translation: mauritian succumbing en masse to help us. the men have voluntarily put the boats out and placed these out at sea. the government says it doesn't have the equipment or expertise to handle the oil spill. france and japan are offering assistance. the japanese company which owns the vessel has apologised for the accident and is sending a team of experts to help with the clean—up effort. but some mauritian ‘s wonder why the visual which ran aground on the 25th ofjuly was left on the shoreline leading to the oil spill nearly two weeks later. the government could have prevented this whole ecological disaster if it had acted promptly. in the next two or three days, this tanker has to be emptied. the mv wakashio's wreckage lies precariously in mauritius's waters, spreading its top six shadow over this

island nation and its delicate ecosystems. catherine byaruhanga, ecosystems. catherine byaru hanga, bbc ecosystems. catherine byaruhanga, bbc news. the ice shelves in antarctica have melted to such an extent that since the mid—nineties they've produced enough water to fill the grand canyon. a study released today has put it all down to higher temperatures in the ocean and warned of the consequences of climate change and increasing melting of the ice. our science and environment correspondent victoria gill has more. ice shelf seems a very humble term for the huge masses of floating ice surrounding antarctica. and to study these vast frozen platforms, scientists had to zoom right out into space. using satellites to make precision measurements of the thickness of the ice shelf showed that in 25 years it lost enough mass to fill the grand canyon with water. the ice shelves that we see melting

in this study are not going to raise to sea level in themselves because they are actually already sitting in the water. they are already floating. the sea level rise comes when those ice shelves reduce the restraint that they exert on the rest of the antarctic ice sheet, which then flows faster into the ocean, causing sea level rise. the effects of all this cold, fresh water entering the deep sea around antarctica are likely to be felt far beyond the polar south. the ocean plays a major role in just controlling the climate around the world. adding a lot of cold fresh water to the ocean kind of changes the way it can transport heat, and that can change global climate and maybe potentially change rainfall patterns around the world. is that what scientists mean when they describe antarctica as the world's thermostat? that what happens to that ice and in that ocean is shifting weather patterns all around the world ? yeah, exactly.

with many of the world's biggest cities by the coast, modelling future sea—level rise accurately is crucial. this study reveals just how much of that accuracy depends on understanding what is happening to the ice at the end of the world. victoria gill, bbc news. and you can get in touch with me and most of the team on twitter, i'm @bbcmikeembley. the white house has been placed on lockdown after secret service agents shot unarmed suspect. he was approached by secret service agent and a bru ptly escorted secret service agent and abruptly escorted from the podium. minutes later, he did return and told reporters that unarmed suspect had been shot and taken to hospital. the president said he did not think the perimeter fence of the president said he did not think the perimeterfence of the high towers had been breached. secret service later treated a mail subject was taken to hospital at 17th and

pennsylvania avenue. that is one block from the white house. more on that as soon as we have it, more on the bbc website. thank you for watching. hello. the heatwave will continue for a few more days for many of us. we had temperatures on monday again of 35 celsius, the fourth consecutive day where temperatures were above 3a celsius. this was the picture in west sussex, lots of sunshine there, but we've also already seen lots of heavy showers and thunderstorms. and tuesday brings us a similar day, hot again with the chance of those thundery downpours. we've got very warm air with us at the moment, as there is across much of central and western europe. but bubbling up in the afternoon, we are set to see those torrential downpours. in fact, we start off tuesday morning already with some really heavy showers, particularly across the northern half of the uk.

a hot, humid start to the day, especially further south. there will be a good deal of sunshine in store for tuesday, but especially during the afternoon, we'll see more of those showers popping up. they could be heavy and thundery with some hail and squally winds with some of those downpours. but as is the nature with these sort of showers, they will be hit—and—miss and there will be long spells of hot sunshine. in the south east, we're likely to see 3a or 35 celsius once again. it's a little bit fresher for scotland, northern ireland and the south west of england, typically the low to mid—20s here. now, through tuesday evening and overnight into wednesday, most of the heavy showers and thunderstorms die away for a time. there could be quite a bit of mist and murk as we've got quite humid airaround. to start off wednesday, a little less humid across the far north of scotland, but for most of us, we are in for the high teens, possibly 20 degrees once again to start the day. so, wednesday a similar day, hot sunshine and scattered showers and thunderstorms as well. it's parts of northern england, wales, central and southern england that are at most risk of catching those thunderstorms through the day on wednesday. fewer for scotland and for northern ireland,

but hot once again, with temperatures up to about 35 celsius in the south east, the mid to high 20s further towards the north and the west. and then heading through wednesday night into thursday, we'll start to draw in this area of low pressure, and it will bring a change into thursday. that's going to be drawing in some fresher air and also further scattered heavy showers and thunderstorms, too. it'll be driest across parts of scotland, northern ireland and northern england, typically the low 20s here. still, we could see 30 celsius down towards the south—east, but not quite as hot as the next couple of days. so, the heat continues, thundery downpours are likely and then things turn a little fresher as we head towards the end of the week. bye for now.
