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 reuturned 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. president trump has just confirmed that there was a shooting outside the white house. here's what the president had to sayjust moments ago. it looks like we're going to be topping records hopefully soon.

excuse me. he was out for a few minutes with the security detail and minutes with the security detailand an minutes with the security detail and an armed officer worked on to the stage there. within a few minutes later, president trump returned to the podium to confirm that there had been a shooting outside the white house. 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 like to thank the secret service for doing their always quick and effective work, but there was an actual shooting and somebody has been taken to the hospital.

ido has been taken to the hospital. i do not know the condition of the person. it seems that the person was shot by secret service. let's get the latest from our north america correspondent, david willis. what happened 7 what happened? it seems to be all over now but the latest pictures were seen coming in shows law enforcement swarming all around the area, around 1600 pennsylvania ave in the park at the rear. the president had just begun his televised news conference, he was in the middle of a sentence as you saw there when the secret service agent approached him and prom ptly agent approached him and promptly escorted him. he was taken to the oval office and remained there for about eight minutes and then returned to the briefing room and told reporters that there had been this shooting outside of the fence surrounding the executive office complex and mr trump

said that the suspect had been shot by the secret service. fox news reporters who were in the area at the time said that he heard two shots rang out and very quick succession and he thought that the suspect was armed and paid tribute to the vigilance of law enforcement officers. but truly an extraordinary site. the site of a president literally being escorted mid—sentence from the podium because of security concerns. so close podium because of security concerns. 50 close to podium because of security concerns. so close to the white house. i can't. but concerns. so close to the white house. ican't. but what concerns. so close to the white house. i can't. but what struck me was remembering the reaction from george w. bush when he was told as he was telling schoolchildren about 9/11. that look on his face. i suppose it is such a tricky one for the white house. you've got the public able to get very close to that building and the railings have kept them away

and you've got the security checks as you go in. but the public can get quite close to the whole of that in central washington, dc. yes and there have been some fence jumpers, the rep and some people shot before but the this played out on live television. this coronavirus briefing that the president was giving. we were told that the white house, the president was not taken to the underground bunker like he was briefly during those rather violent protests in lafayette park during the start of the black lives matter series of protests a nd black lives matter series of protests and he was kept there for eight minutes in the oval office and security service was pretty alarmed by the whole thing but they are still there

on the premise and surrounding the premises and although it does appear this incident is over, the suspect has been taken to hospital according to the president himself. thank you very much. 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 would joke that they do not know when they they do not have a government. for protesters were celebrating tonight and they see this is only the beginning of a long process. they want to speak of the problem and to go in there when the president to leave too.

my report contains images that some 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. they want to live in a country where the life savings are not wiped out by a financial and economic crisis in theirjobs and education and health care does not depend on sectarian and political pathos. clean water where the traffic lights work in the rubbish gets collected, none of that happens. most of all, they want answers as to what happened here, who was responsible for this disaster and why government after government ignored warnings? saying that there was a bad to keep tonnes, many thousands of tonnes of toxic chemicals in the heart of the city. but the lebanese did not

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. police in belarus have clashed with protestors for a second night after sunday's disputed election victory for president alexander lukashenko. police say one demonstrator died, when a bomb he was carrying went off. the opposition has rejected the election result and demanded a recount. from the capital minsk, abdu—jalil abdu—rasoo—lov reports. long live belarus, the crowd is chanting. they came out to protest against what they claim is a rigged vote. after 26 years of president lu kashenko's rule, these people want to see changes in their country. such things in what is often called europe's last dictatorship would have been unthinkable a few months ago.

but the regime here doesn't tolerate any dissent. officers are detaining people at random, often quite violently. protesters are saying this is a scare tactic to keep people off the streets. but it seems that these heavy—handed tactics are not stopping the protests. people are still gathering in the streets despite the crackdown. translation: my son is 26 years old. they arrested him just because i took a picture of a police car. they should have taken me. i'm not leaving until they bring my son back. on a visit to an agricultural facility today, mr lukashenko blamed the protesters are stoking the violence. translation: they wanted to seize government buildings in some locations. this is what i've said before, if some do not believe me, now they will. they want to start unrest here but i warned that there would be no revolution here.

massive crowds gathered outside polling stations on the election day, hoping that their votes would bring an end to mr lukashenko's rule. many said the country has stagnated under the many years of his presidency. today, the opposition leaders went to the election commission to lodge a complaint. they are calling on president lukashenko to admit his defeat in the election. officially, lukashenko has won in the elections but we know and people on the streets and in factories and in the whole of belarus, they know that he doesn't win this election. and now it's probably the most important moment in the history of modern belarus. the question is will the people be able to keep up the momentum and bring real change?

stay with us on bbc news. still to come: a race against time in mauritius, after a government warning that run—aground cargo ship, which has been leaking oil, 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. idi amin, uganda's brutal former dictator, has died at the age of 80. he's been buried in saudi arabia, where he lived in exile since being overthrown in 1979.

2 billion people around the world have seen the last total eclipse of the sun to take place in this millennium. it began itsjourney off the coast of canada, ending three hours later when the sun set over the bay of bengal. this is bbc world news. the latest headlines: president trump is escorted from a white house briefing after security shoot an armed suspect outside the building. protests on the streets of beirut — as the entire lebanese government steps down — after last week's catastrophic explosion. 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. the situation in hong kong has become increasingly intense — so much so that activist nathan law has left the country and is living in an undisclosed location. i sopke to him earlier — he had this to say about the arrest ofjimmy lai. he had this to say about first he had this to say about of all, it is definitely a first of all, it is definitely a retaliation for the sanctioning of the us on hong kong and that would be another step two squash the freedom of the hong kong people to make them silent, to create a much larger terror and political fear and hong kong stop by to encourage others not to do anything similar? we still have no a ccess anything similar? we still have no access to what the police is

accusingjimmy no access to what the police is accusing jimmy lai no access to what the police is accusingjimmy lai and the others of, but we suspect it is related to some international lobbying work and definitely showing that the chinese government has been very hostile towards those people who have been on the fronts of the movement. you left hong kong several weeks ago, i think now. has this intimidated the pro—democracy groups? has it stopped dissent now? because it is so draconian? well, i announced that i am and linda couple of weeks before it i've met up with a couple of politicians. the secretaries andi politicians. the secretaries and i have been talking about the demands and opinions of the hong kong people for the past few weeks. after my arrival in london, it is making me have more room to do international advocacy work. i think that

kind of implementation would help. these statements of angen help. these statements of anger, the statements of criticism from international governments do not seem to be making any difference.” governments do not seem to be making any difference. i think it takes a process. we have been witnessing that the change of our policies, no matter in the uk and europe, and we hope that there will be some actions and counter actions on the implementation of the national security law. how fearful are you for your friends and family left back in the territory? have you been able to contact them? of the been approached?” haven't had direct contact with them and we are very worried about the situation. there is great danger and we are aware that patient does target these

people because they have some agents and they are hong kong people who want to fight for justice and hong kong. so they are ina justice and hong kong. so they are in a dangerous situation. you have mentioned that you talk to the shutter —— shadow foreign secretary. we have seen the offer of the british government for the passports, but what more can countries do with the sanctions and identify and isolate individuals who shall i think i think it takes time to overturn this very aggressive policy and it is a definitely long journey, offering policies for now, like sanctioning under the gap, in the uk, chief

executives who should be held responsible for the human rights violations in hong kong will be a very good first contraction to be done. 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. 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 reports. it's a rush against time for crews trying to empty thousands of tonnes of fuel from the mv wakashio. days of bad weather are making theirjob harder. even though some of the oil has been removed, 2,500 tonnes remain. mauritius's prime minister is warning the boat could split, sending it all into the indian ocean. translation: we know that there are several quirks which are continuing to develop and these quirks, unfortunately, mean that there is a major risk that the carrier breaks up into two. closer to land, the damage is clear to see. a thick, toxic sludge of fuel seeping from the ship is invading endangered coral,

wetlands and lagoons. the clean—up effort here relies on volunteers. some are making these homemade brooms, filled with sugar cane stocks and even hair to soak up the oil. these waters are everything to mauritians, a source for its lucrative tourism sector, a provider of food. translation: mauritians are coming en masse to help us make the oil booms. the boatmen have voluntarily put their boats out of disposal to go and place these oil booms 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 nagashiki shipping, 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 mauritians wonder why the vessel — which ran aground on the 25th ofjuly — was left on the shoreline,

leading to the oil spill nearly two weeks later. government could have prevented this whole ecological disaster if they had acted promptly. in the next two or three days, this tank has to be emptied. the mv wakashio's wreckage lies precariously in mauritius's waters, spreading its toxic shadow over this island nation and its delicate 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 we see melting in this study are not going to raise to sea level in themselves because they're actually already sitting in the water. they're 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 changes the way it can transport heat. and that can change global climate and maybe, potentially, even change rainfall patterns around the world, as well. 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 7 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's happening to the ice at the end of the world. don't forget there's lots more on all the stories we're covering on our website — that's bbc.com/news — or you can download the bbc news app for your tablet or smartphone.

you can reach me on twitter — i'm @bbctimwillcox. 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.
