border during a mass protest. mahmoud abbas also called on the un security council to take action. the israeli army said the protesters had been throwing stones and fire bombs at its soldiers. yolande knell reports from jerusalem. a chaotic rush to the hospital, with hundreds of palestinians injured in gaza. a call for peaceful marches turned to violence, as protesters headed towards 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. and this was just the start. palestinians are planning a series of protests until mid—may. that will be 70 years on 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 their claim to the land. translation: we are here to stress our right to return. sooner or later, we must go back. translation: we want to tell the world that returning to our land is non—negotiable. but israel says gaza's leaders are cynically exploiting ordinary people to stir up unrest. translation: hamas and other palestinian groups are calling their protest "the march of return". however, as events unfold, it's the march of chaos. these are aggressive riots. gazan families are now being urged to stay at protest camps along the israeli border, and that will ensure that tensions here remain high in the weeks ahead. yolande knell, bbc news, jerusalem. russia has told britain it must further reduce the number of diplomatic staff it has in the country. the move is the latest development in the escalating row over the poisoning of a former russian spy in the uk.

the kremlin has also expelled diplomats from 22 other countries including the us, germany and spain. sarah rainsford reports from moscow. 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. we arejust dropping we are just dropping out of that report early, we are going to take you to a live news conference where the cricketer david warner is now speaking after the week of controversy in australian cricket. let's listen to what he is saying. controversy in australian cricket. let's listen to what he is sayinglj apologise for my actions and i take full responsibility for my part in what happened on day three of the test. to cricket australia, i

apologise for my actions and be a fa ct apologise for my actions and be a fact it has had on my game —— via fa ct fact it has had on my game —— via fact it has had on my game —— via fact it has had on my game —— via fact it has had on our game under your ca re fact it has had on our game under your care and control. —— the effect. i fully support your review into the culture of the australian cricket team. to south africa, the players, administrators and fans, i apologise unreservedly for my part in this and i am sorry. i brought the game into disrepute on your soil. south africa is a fine cricketing nation and deserves better from its guests and from me. to all australians, whether you are a cricket fan or not, i apologise for my actions. and i am sorry for the impact those actions have had on mike —— on our country's reputation. ican mike —— on our country's reputation. i can honestly say i only ever wa nted i can honestly say i only ever wanted to bring glory to my country through playing cricket. in striving to do so, i made a decision which

has had the opposite effect. and it is one that i will regret for as long as i live. i do realise that i am responsible for my own actions, and the consequences that that brings. it is heartbreaking to know that i will not taking the field with my teammates i love and respect, and that i have let down. right now it is hard to know what comes next, but first and foremost... cries. is the well—being of my family. in the back of my mind, isuppose of my family. in the back of my mind, i suppose there is a tiny ray of hope... that i may one day be

given the privilege of playing for my country again. but i am resigned to the fact that that may never happen. in the coming weeks and months i am going to look at how this has happened and who i am as a man. to be honest, i am not sure right now how i will do this. i will seek out advice and expertise to help me make serious changes. i want to apologise to my family, especially my wife and daughters. your love means especially my wife and daughters. youi’ love means more especially my wife and daughters. your love means more than anything to me. i know i would not be

anything without you. i'm very sorry for putting you through this and i promise you that i will never put you in this position again. before i ta ke you in this position again. before i take questions, i want to again say thank you. i take full responsibility for my part in what happens and i am deeply sorry for the consequences of what i was involved in. i failed the consequences of what i was involved in. ifailed in my responsibilities as vice captain of the australian cricket team. i will now answer your questions. in inaudible question. it is tough for me to talk about,

where my thoughts base was on that day, given the circumstances that happened in durban. —— thought space. i am happened in durban. —— thought space. iam here happened in durban. —— thought space. i am here to take full responsibility of my actions. of the pa rt responsibility of my actions. of the part that i played in, that happened in day three, in cape town. i am extremely sorry and i really, really regret that. it is going to be a decision that will stick with me for the rest of my life. who else was involved? you the rest of my life. who else was involved 7 you were the rest of my life. who else was involved? you were involved, steve smith was involved, cameron bancroft was involved. inaudible. the players, the coach, who knew... inaudible. i am here today to accept my responsibility for my part, my

involvement, in what happened in cape town. it is inexcusable. i am deeply sorry. as i said, i will do everything i can to learn that respect back from the australian public. sorry, sorry, excuse me, one question each. was it your idea? as isaid, i'm question each. was it your idea? as i said, i'm here to take full responsibility for the part that i played in this. it is extremely reg retta ble. played in this. it is extremely regrettable. i'm very sorry. i really wa nt regrettable. i'm very sorry. i really want to just move on from this. inaudible. missjudged the mood, or were surprised by how the public took it? —— misjudged.” mood, or were surprised by how the public took it? -- misjudged. i am not surprised at all. we let our country down. we made a bad

decision. i played my part in that. asi decision. i played my part in that. as i said, it is going to take a long time to learn that respect back from the australian public. it is really ha rd to from the australian public. it is really hard to sit here today knowing, seeing, my friends and my family, who are playing in south africa at the moment, india's fourth test —— in this fourth test, which i wish i was part of. inaudible. on your rhone in this crisis? —— on your own. the australian cricket tea m your own. the australian cricket team are my family. i really regret what happened on day three. as i said, ijust really wish i could either today, on that field with them. that is one thing i am really

going to miss, this next 12 months. sorry, mate, you have had your question. at the time, the icc said it would be a one match ban and cricket australia did nothing. did you realise how serious the crime was at the time, or was it all too late, once it happened? this... we know what the consequences are when you make horrible decisions like this. as i said, i'm extremely

sorry for my part and my role that i played in this. and i really wish and hope that steve and cameron have the same support that i have with me, because it is going to be a tough and emotional time, these next 12 months. dave, you considering retirement? -- are you. that is something that i'll continue to sit down with my family, and weigh up all my considerations before i make any decisions. can you say that you have never done this before in any match that you have been involved in... inaudible. asl match that you have been involved in... inaudible. as i said before, i am here to accept my responsibility for the part that i played in day

three of the cape town test. inaudible. dave, what is your relationship with steve, cameron, do you think it can be repaired? we are mates. we have grown up with each other. we have played on the field for a long time with each other. it is... it is going to be really tough, not being able to partake in the next 12 months, notjust with the next 12 months, notjust with the rest of the team, but with steve and cameron. because we made a decision that was inexcusable and extremely regrettable. last question. do you feel you are being made a scapegoat? are you being singled out? as i said before, i am here to speak about myself and take

responsibility for the part that i played in this... whose idea was it? that's it, thank you. thank you. was it your idea? so, that was another very emotional press conference from an australian cricketer, this time david warner. that was to sore speaking just then, he along with his teammates steve smith and cameron bancroft have been banned for ball tampering in a test match against south africa. —— who you saw speaking. they were using sandpaper to rub the ball, which would then affect its flight. that was david warner saying he would regret his decision for as long as he lived, apologising to his family, taking full responsibility, saying that he failed in his responsibilities as vice captain. a very difficult week for australian cricket. let's move on. all flights from stansted airport have been cancelled after a shuttle bus caught fire just outside the terminal building. passengers were asked to leave the airport and re—book

with their airline. the fire caused smoke damage to the front of the terminal, but no one was hurt. thomas magill reports. pa rt part of the terminal was evacuated devastating start to the holidays are many. is due to the hugh shannons, and are, many other hundreds are well into the hundreds, perhaps a thousand, i would say, in that departures area, it is sad to hear. some abandoned cars and left the airport had nowhere to go. the bus was completely destroyed by the

blaze. officials say it was caused bya blaze. officials say it was caused by a knowledgeable fault. tonight, passengers are being told to go home and rebook their flights with their airlines. thomas magill, bbc london news. let's speak to grace corcoran. she'd arranged and paid for her sister to fly from ireland to london for her birthday, when they got caught up in the chaos at stansted. good to have your malign. grace, it is your sister, louise, that went to the airport in court. —— good to have you on the line. tell us what happened. she was basically at the airport for about four hours. and thatis airport for about four hours. and that is the time when the departure screens kept changing scene the fate would be leaving later and later. —— flight. would be leaving later and later. —— flight. there was no one there to direct anybody. we were checking the twitter updates and speaking on the

phone, and after about four hours of waiting, and aer lingus member of staff told in their flight had been cancelled. this put some passengers on ryanair flights, as cancelled. this put some passengers on ryanairflights, as many as they could. and passengers were left to go to security. they had to queue up a couple of hours at the ryanair desk in the arrivals hall, to try and rebook their flights. desk in the arrivals hall, to try and rebook theirflights. now, my sister was chewing for flights to gatwick. but i had to pay full price. the flight prices were going up price. the flight prices were going up by price. the flight prices were going up by about £50 every ten minutes. they are basically capitalising on the fact that this incident happened and judging people through the nose,

getting new flights. i then contact ryanairand getting new flights. i then contact ryanair and there were not responding. i applied for a refund and they refunded me i think to do bounce out of the money i paid. —— they refunded me i think £20 under they refunded me i think £20 under the money paid. she is to pay for taxis. we miss out on tickets that we have pay for fortunata and brunch tomorrow. she is flying in tomorrow, but it would dampen on the weekend. it is not ryanair‘s fault, but their lack of customer service, and the fa ct lack of customer service, and the fact that they did not— i didn't even get a text at a vocation saying the flat had been cancelled. i did discover that on twitter. it is not good enough. it is really bad customer service. yes, it is not a cce pta ble customer service. yes, it is not acceptable at all. i can hear the frustration in your voice, great. it is off and communication that is the

keeping of these events. —— it is often communication. and you are not getting it in ireland or england, is that right? exactly. we got the information through other sources. as esso, through aer lingus staff, but via ryanair, we received nothing. —— as i said. we got no communication whatsoever. to be honest, i hate seeing, buti communication whatsoever. to be honest, i hate seeing, but i fly with regularly back and forth to ireland, andi with regularly back and forth to ireland, and i think out of the last 15 flights i have had, many have been cancelled. customer service — that have taken it. so it is just kind of— it is rather we can, i suppose. it was the people who have families. all the flights will be go tomorrow, so a lot of people will

not be a will to get to london for the weekend. sorry, greece, we are up the weekend. sorry, greece, we are up against the clock. but we hope your submissions to govern we appreciate you speaking to us here in bbc news. —— we hope your problems are dealt with, and thank you for speaking to us here in bbc news. stay with us on bbc news. still to come, scientists in denmark make a quantum leap in the race to build the world's fastest super—computer. the accident that happened here was of the sort that can, at worse, produce a meltdown. in this case, the precautions worked but they didn't work quite well enough to prevent some old fears about the safety features of these stations from resurfacing. the republic of ireland has become the first country in the world to ban smoking in the workplace. from today, anyone lighting up in offices, businesses, pubs or restaurants will face a heavy fine. the president was on his way out

of the washington hilton hotel where he had been addressing a trade union conference. the small crowd outside included his assailant. it has become a symbol of paris. a hundred years ago, many parisians wished it had never been built. the eiffel tower's birthday is being marked by a re—enactment of the first ascent by gustave eiffel. this is bbc news. the latest headlines: at least 15 palestinians are reported killed and hundreds —— 16 palestinians are reported killed and hundreds injured as israeli security forces confront protesters along the gaza border. another day of diplomatic expulsions after the salisbury nerve agent attack stokes east—west tensions.

scientists say it's the technology that could revolutionise computing. it's called quantum computing and for years companies have been vying to build a fully operational quantum computer, which could process information much faster than today's most powerful super—computers. now scientists at microsoft say they're on the verge of a major breakthrough. our technology correspondent rory cellan—jones explains. copenhagen, and it's pretty cold outside, but inside a university lab, there's a place that's even colder. if you look right up here on this gauge, you'll see that the inside of that refrigerator is sitting at three hundredths of a degree above absolute zero. that's 100 times colder than deep space. this may be the coldest place in the universe. and this is why. embedded in this chip is a qubit, the building block for the computer of the future, which will only work under these extreme conditions. microsoft is working with scientists here and around the world to build a quantum computer. they're confident they're about to make a major breakthrough. if they succeed, there's a huge prize. quantum really represents

a giant leap forward from today's technology. we can begin to solve problems that would take us today more than a lifetime of the universe to solve, in seconds, hours or days. so how does a quantum computer work? drill down into a conventional computer and you'll find the bit, the basic unit of information, which is either a zero or a one. think of it as a switch which is either on or off. but at the heart of a quantum computer is the qubit, and the magic here is it can be both one and zero at the same time. the switch can be both on and off. this supercharges any computer programme, making impossible problems easy to solve. we could find answers to climate change, make rapid progress in artificial intelligence, and break encryption — secure codes would be simple to crack. first, though, there are huge challenges in creating qubits stable enough to be useful

in a commercial quantum computer. microsoft thinks it's got a unique way of doing that. by making a better qubit to begin with, you'll need fewer of them to build the full quantum processor. but there's stiff competition. google, ibm and scientists in labs like this one in london are all making breakthroughs, and so far they've made faster progress. so microsoft is starting further behind, they're still trying to demonstrate a single qubit, but their approach is unique. its qubits may be much better protected against errors, so if they get their one qubit to work, they could leapfrog these other approaches quite quickly. back in copenhagen, they're confident they're on the verge of a breakthrough which will lead to a commercial quantum computer within five years. if that's true, and it's a big if, the world will change in all sorts of ways. a few more stories for you, now.

all around the world, christians have been marking good friday — the day whenjesus was crucified. pope francis led the events in rome, presiding over the way of the cross procession. a cross was carried around the colosseum — the roman stadium, which is believed to have been the scene of many executions of christians in the early years of the church. the ceremony commemorates the suffering and crucifixion ofjesus — as the catholic church prepares for easter. arnold schwarzenegger has come out of emergency surgery after a heart event that required emergency surgery. and the palestinian president has blamed israel for the deaths of 16 demonstrators are the violence flared across the gaza border. monitor bus called for action against escalating daily aggression by israel. —— mahmoud

abbas. you're watching bbc news, stay with us. don't forget you can get in touch with me and some of the team on twitter — i'm @duncangolestani. some parts of england had a washout of a good friday, some areas in western scotland were babes in sunshine. those where the differences will continue as we go through the west of this weekend. there will be some rain around at times, snow, particularly easter monday as we will see in a moment. it is disappointingly cool but there are dry, sunny areas too. they will come in the day ahead, the further you are away from this area of low pressure. this brought some very wet weather for some of us during good friday but you are further away still in northern and western scotland and northern ireland. so you will do quite well, but the eastern scotland into england and wales, you will get plenty of clout at there will still be some outbreaks of rain, some sleet and snow into the higher hills. but it is not as heavy, not as wet as it was during good friday, more of this will peter out later in the day. there will be some brightness developing in the south—west

of england, western fringes of wales, to the western pennines, but especially into northern ireland, north and west scotland. nowhere is particular warm and actually it is quite cold into north—east england, with a brisk breeze. a lot of that pack she wet weather will fade away during the night, into sunday morning. clearing skies into northern and western parts of britain will allow temperatures to give away into a touch of frost, there will be fog patches into sunday. but it is a better day on sunday, that is if —— on easter sunday, in between weather systems, it is the most widely dry day of this easter weekend. there will be a good deal of clout around, one or two showers to be had here and there, and some drizzle. but many places will be dry, a few breaks in the cloud here and there, maybe some developing through eastern parts of england. but expect a good deal of clout. and rain coming back to south—east england and southwest wales later in the day, we have seen a lot of rain here, so watch out for potential problems from that. and from the rain and so pushing northwards into easter monday, because the moisture is feeding into cold air, sofa parts of wales and the midlands northwards, some sleet

and so mainly on hills, but also possible and lower levels. the far north of scotland staying dry during daylight hours and in the southleigh brighten up a bit after some heavy showers. but it is a possibility of snow, and is a busy travel day on easter monday which we are watching closely. if you have travel plans keep across the forecast because there is a risk of some disruption and we will keep you updated on that. this is bbc news, the headlines: the palestinian president has blamed israel for the deaths of 16 demonstrators, after violence flared along gaza's border. mahmoud abbas called on the un to take immediate action to protect palestinians against what he called "escalating daily aggression" by israel. russia has announced that it's expelling diplomats from 23 more countries, sharply escalating a row over the poisoning of a former spy living in britain. an unofficial tally put the number of expelled diplomats at 59. the former vice—captain of the australian cricket team has apologised and said he takes en "full responsibility" for his role in the ball—tampering scandal.

david warner said he let his country down and made a "bad decision" in the last test match against south africa. and he admitted he might never play for the team again. now on bbc news, it's time for click.
