residents be allowed to return to homes that are now in israel. at least 15 palestinians have been killed — and 350 wounded — in clashes with the israeli defence force. a 16—year—old boy is said to be among the dead. the israeli military oversees a no—go zone along the gaza border, citing security concerns. palestinians have pitched five camps near the border — seen here in yellow. israel has deployed tanks and snipers and is using tear gas to force palestinians away from the border. the bbc‘s yolande knell is injerusalem. this was one of the largest demonstrations that has taken place along the israel/gaza border in recent yea rs. along the israel/gaza border in recent years. an israeli official told me about 30,000 people took part. there was some family entertainment in the encampments

that have been set up. but as the day went on, many palestinians approached the perimeter fence and the israeli forces who were waiting there. a chaotic rush to the hospital. with hundreds of palestinians injured in gaza. a call for peaceful marches turned to violence. as protesters headed to the israeli border. israel's military says it used tear gas and opened fire to stop anyone illegally crossing into its territory or attacking soldiers. this was just the start. palestinians are planning protests until mid—may that. will be 70 years from the creation of the state of israel. palestinians see it as their catastrophe, when hundreds of thousands of people fled their homes. and many here have never given up theirclaim homes. and many here have never given up their claim to the land. translation: we are here to stress

oui’ translation: we are here to stress our right to return. sooner or later we must go back. translation: we wa nt we must go back. translation: we want to tell the world that returning to our land is non—negotiatable. returning to our land is non-negotiatable. but israel says gaza's leader are exploiting ordinary people to stir up unrest. translation: hamas and others are calling this the march of return, but it is the march of chaos. these are aggressive riots. families are being urged to stay at protest camps along the border. that will ensure that tensions here remain high in the weeks ahead. you mentioned the protests are scheduled to take place for six weeks? that's right. it is because in the middle of may it will because in the middle of may it will be the 70th anniversary of the

palestinians call the catastrophe. it is important for palestinians in gaza. there are about two million people in gaza and 1.3 are classed as refugees. they are the descendants of people who flod. so there is a consciousness of what happened in 19118 and many of the tents have the names of palestinian villages that people have been, see as their homes. let's speak to aaron david miller who is from the woodrow wilson center think tank. he's a middle east analyst and former state department negotiator. given the series of anniversaries that are coming up, land day, the creation of state of israel in six weeks, given the deteriorating

conditions in gaza are the scale of the protests inevitable do you think? they occur against the backdrop of a conflict that is simply not resolvable. we are going to function for the future between in the space between a two—state solution that is too important to abandon and one that it is impossible to implement. you have a perfect storm — aggrieved conditions, humanitarian conditions, which from the perspective of the palestinians is an open air prison. you have hamas under pressure from abbas. terrible rivalry. squeezed by the egyptians, looking for a way to break out and capitalising on what was a grass roots movement to protest. but exploiting it and you have got an israeli reaction that is

determined to ensure that there is no penetration of the border under what circumstances these deaths, these 15... males were killed is unclear. i doubt whether the lives of israeli soldiers were threatened. so the israelis are prepared i think to send a signal that since this is the beginning of the protests, they're creating a pre—emptive deterrence. it is a disaster. in the end i cannot imagine it is going to get worse before it gets worse of and it is going to continue to escalate without any political solution or any de—escalation that is capable of calming it down. this is capable of calming it down. this is day one, we are talking of a projected six—week process. there must be some resolution. who should be involved in negotiations in this?

remember, you have seen three in the last decade, three cross—border confrontations between israel and hamas. in 08 and 12 and 1a and these we re hamas. in 08 and 12 and 1a and these were simply the... interludes of violence sandwiched between prolonged periods of instability. frankly right now the trump administration has taken itself off the front line as a credible mediator. the international community failing to respond to an even worse situation in syria, seems to have no capacity to deal with the situation. the israelis and palestinians fundamentally mistrust each other and you have the perverse dance between the occupier and the occupied. so again i wish i could

offer some... route out of this. but i don't see. the problem between israeli and palestinians, dormant for the last five years as the world focussed on other issue from the arab spring to the iran nuclear issue, has now reasserted itself. i don't think frankly there is enough pain and the prospects of gain that either side is prepared to inflict upon one other to create the urgency required to get the parties to own this and take responsibility for de—escalating it. it is a very grim prognosis. i'm sorry to you know... my prognosis. i'm sorry to you know... my analysis is annoyingly negative, but it reflects a very grim situation. we value your analysis. thank you for your time. in an afternoon of tit—for—tat

diplomatic expulsions after the salisbury nerve agent attack, russia has sent home dozens of embassy staff from 23 different countries. and it says it reserves the right to take action against a further four. in the past hour france has confirmed that four of its diplomats have been expelled too. russia has also given britain one month to cut its diplomatic contingent in moscow to the same size as the russian diplomatic mission to britain. from moscow, sarah rainsford reports. it was quite a sight. a stream of ambassadors summoned to russia's foreign ministry. they came from more than 20 countries to hear their punishment. each one had backed britain, and accused russia of the nerve agent attack in salisbury. the german ambassador emerged to say moscow still has questions to answer over the poisoning. but his country is now losing four diplomats here. in total, well over 100 willjoin a mass exodus from moscow. there have been extraordinary

scenes here all day. as, one by one, ambassadors have been called in to the foreign ministry. the timing of this, the choreography, seemed meant to send a message — that russia will hit back at any moves made against it by western governments. and today moscow decided to escalate. the british ambassador was summoned again, ordered to cut his staff even further. it's important to bear in mind why this crisis has arisen in the first place. it is the use of chemical weapons on the streets of the united kingdom that has threatened the lives of a number of people in my country. 23 british diplomats have already left this embassy. now the uk has the match its total diplomatic presence here to the russian headcount in the uk. this move is a clear sign that vladimir putin is determined not to give in under pressure. expulsions look so easy. you don't have to pay a high price on either side for expulsions, but it is not the case.

i'm afraid if the whole fabric of the relationship gets thinner and thinner, we have a real problem. that problem is already here. western countries seem determined to show russia it has crossed the line, but the kremlin still calls the accusations against it is outrageous, and warns that further sanctions could follow. mark zuckerberg, the chief executive of facebook, says he strongly disagrees with a leaked memo from 2016, written by a top executive at the company. the memo, which was first published by the buzzfeed news website, described what it called the ‘ugly truth', that anything it did to grow facebook was justified. in the leaked memo, andrew bosworth apparently wrote that connecting people can be bad if they make it negative. maybe, he writes, it costs a life

by exposing someone to bullies, or someone dies in a terrorist attack co—ordinated on our tools. he goes on to say that: "we will still connect people" and ‘anything that allows us to connect more people more often is de facto good.‘ earlier i spoke to ryan mac — from buzzfeed news. i asked him more about andrew bosworth‘s comments in response to the leaked memo. probably after we published the story, he said something to the extent of, "i didn‘t agree with what i wrote, even when i wrote it." which was a kind of interesting take. but what‘s interesting about this memo is that for so long facebook has said that facebook is really the best place for people to connect, for the whole world to connect, whoever you are. and they really haven‘t expressed this idea publicly that they‘re grappling with all the fundamentally bad things that could happen on their platform. this memo shows that they were thinking about those things even back injune 2016 that fundamentally bad things, whether that‘s the organisation of terrorism plots, or suicides could happen

on its platform and it is quite telling. this is the type of memo that would have gone to the whole company, to all employees, would it? yeah, it was a post sent to employees only. as i understand it, there was quite a bit of debate in the comments section as well of that post. it caused quite a stir i believe and a lot of people didn‘t agree with it. even at the time when it was posted. but it has only come out now, that is quite interesting, why do you think that is? well, facebook, like a lot of technology companies, has a culture that frowns upon leaks, frowns upon internal information getting out into the public and these cultures are very protective of what they say internally and they have kind of bred their employees to act in certain ways. so this is kind of one of the first cracks we have seen in facebook‘s

armour in quite some time. stansted airport in london has cancelled all departing flights after a bus caught fire outside the terminal building earlier today. flights arriving at the airport have also been significantly disrupted. stansted is to the north of london, it‘s the city‘s third largest airport after heathrow and gatwick. the fire service says the bus has been totally destroyed and the front of the terminal building has been damaged by smoke. it‘s thought the fire started by accident. earlier we spoke to a bbc producer who is stuck at stansted airport.|j was due to fly to shannon and i like

many others, hundreds, well into the thousands here at least a thousand people i would say, in the departure area in sta nsted, people i would say, in the departure area in stansted, who on this good friday evening is stranded at sta nsted. basically friday evening is stranded at stansted. basically what‘s happened in the last half an hour, that initially it said on the board, people were all congregating around the board. we will continue to monitor that. stay us with. stay with us on bbc world news, still to come... 220,000 people from el salvador are facing deportation from the us next year. we‘ve got a report on those that have already returned — and the challenges they face the accident was of the sort that can produce a melt down. the

precautions worked, but think didn‘t work well enough to prevent old fears about the safety feature of these stations from resurfacing. the republic of ireland has become the first country in the world to ban smoking in the work place. anyone lighting up will face a heavy fine. the president was on his way out of washington hilton hotel. a small crowd included his assailant. washington hilton hotel. a small crowd included his assailantm washington hilton hotel. a small crowd included his assailant. it has become a symbol of paris. a hundred yea rs become a symbol of paris. a hundred years ago many wished it had never been built. the eiffel tower‘s birthday is being marked. this is bbc world news today.

the latest headlines: at least 15 palestinians are reported killed and hundreds injured as israeli security forces confront protests along the gaza border. western ambassadors have been summoned to the russian foreign ministry as tit—for—tat expulsions continue over the poisoned spy the trump administration recently announced it will lift "temporary protected status" or tps for around 220,000 people from el salvador next year, who will then face deportation from the us. with limited support networks in place, el salvador is already struggling to cope with so many deportees. and the returnees are also trying to manage in a country many left decades earlier through poverty or gang—related violence. will grant reports the trump administration said it has sent these deportees home. but for many, home was the united states. they‘re met with a little kindness —

a meal, a chance to call family, medical attention. and they‘re reunited with their possessions removed from them in us detention centres — from the most basic to the most cherished. these are the first steps of rebuilding their lives in in el salvador — a country some left a few months ago, but others haven‘t seen since they were small. this man has no one in el salvador. instead he turned to the man he was shackled to on the plane. he opened his home and his family to a stranger. sharing what little they have. translation: these people are my only support, i have nowhere to go. the situation here is so bad and dangerous, you could easily be killed. so when i arrived at the airport my only plan was to try and head straight back to the us through mexico. translation: he told me his story that he was coming back to nothing and had no one to support him back here. so i told him, look, i'll help you,

don't worry, somehow we'll get by. they have found work through the church, butjose‘s predicament is common — many deportees return to hostile and unfamiliar surroundings, a place president trump recently described in the crudest terms. politicians in el salvador know much needs to be done to create conditions in the country to prevent the exodus. some are urging the trump administration to change its thinking and its language about immigrants. when you have that kind of discourse you reinforce stereotypes and division and you reinforce — in many cases it essentially the politics of fear. still the waves of deportees return. 0ften having left children, spouses, homes and businesses behind. this man hasn‘t stepped foot in el salvador in 1a years and his kids remain in the us.
