our top story: mark zuckerberg apologises for breaches of data security at facebook, affecting the accounts of 50 million users. the suspect in the texas bombings blows himself up, leaving a recorded confession. police say it points to a very challenged personal life. brexit is set to dominate today's eu summit in brussels, with leaders publishing their vision of the future relationship between the uk and europe. it is magic until you understand it, and thereafter it is mathematics. also coming up in the business briefing: trading blows with beijing. the white house vows to hit back at china over intellectual property theft. this is the briefing, i'm sally bundock. and we will be looking at facebook

in the business briefing. facebook‘s founder has broken his silence and admitted the social network made mistakes in its handling of users‘ data. mark zuckerberg also accepted there had been a breach of trust, and promised to make changes. it follows the scandal over cambridge analytica, the british company accused of mining the data of 50 million people to influence the 2016 us election, although the firm denies any wrongdoing. here is what mark zuckerberg had to say about how they have to change heading into other elections this year, including the us midterms. this isn't rocket science. there is a lot of hard work we need to do to make it harder for nation like

russia to do election interference, to make it so that trolls and other folks can't spread fake news. but we can get in front of this, and we have a responsibility to do this not only for the 2018 midterms in the us, which will be a huge deal this year, and that is a huge focus for us, but there is a big election in brazil, there are big elections around the world, and you can bet that we are really committed to doing whatever we need to. 0ur correspondent in washington, chris buckler, has more on what mark zuckerberg has pledged to do. he's been criticised for being silent throughout these allegations and claims that have been made time and time again over the last few days. but finally now the face of facebook has spoken. in the american interview with cnn, he talked about two things.

what he's going to do about the past, and the allegations the information was used and what he would do in the future. he says that they will have a full forensic audit of those applications that may have used information, and he made a commitment to contact every user that potentially had their data breached. and potentially is a very important word because frankly, there is not going to be any certainty i suspect whether or not everybody‘s information was breached, and i'm not sure he is able to say that about anybody. so i think we will talk about potentially anybody who has had their data breached. also, he talked about going forward. he said with regard to the 2016 presidential election, they weren't on top of potential russian interference orfake news. and he said they needed to do more, particularly with elections coming up. that's notjust the us midterms here in america, but also elections in india, brazil, and around the world.

it gives you the sense that mark zuckerberg is having to listen to politicians notjust in the uk, notjust the us, but right around the world, who are concerned about how information is being used on facebook, and how information could be used going forward. mark himself has been asked specifically to appear before committees in london and washington. he was asked about that. he wouldn't give a strict commitment. he said it's something he may be happy to do. "i am happy to do it if that is the right thing to do." i suspect that a lot of politicians both here in washington and in london will think it is not just the right thing to do, but it's an important thing that he has to do. police in texas say the man suspected of a string of bomb attacks in the state left a 25—minute recording about the six devices he had constructed. mark anthony conditt blew himself up while being chased by police officers. investigators say with a reasonable level of certainty there are no more

devices to endanger the public. lebo diseko reports. after three weeks and the city gripped by fear, this. the scene after the man thought to have carried out the bombings tree in austin blew himself up. police had been chasing him when pulled over, and asa been chasing him when pulled over, and as a member of the swat team approached, the suspect set off another bomb. now police say that mark anthony conditt left the video confession. 25 minutes recorded on his phone, explaining how he instructed the six bombs, and the key differences between them. but as for a motive, police say it is not terror related. what i can tell you, having listened to that recording, he does not at all mention anything about terrorism, nor does he mention anything about hate. but instead, it is the outcry of a very challenged

young man talking about challenges in his personal life that led him to this point. it is this cctv footage that helped authorities identify and track conditt down. it is from the next—door in south austin, the scene of the latest parcel bomb explosion. five of the six devices went off, killing two people and injuring seven others. and as police search properties connected with conditt on wednesday, a number of those injured we re wednesday, a number of those injured were still in hospital. his family home was also searched, and an art said ina home was also searched, and an art said in a statement that they are devastated and rogue and —— aunt. she said their thoughts and prayers are with those families that have lost loved ones. let's brief you on some of the other stories making the news: at least 17 people have been killed and more than 30 injured in a bus crash in thailand. police say the bus was going down a hill in central thailand when it

collided with a lorry. the bus broke into two parts. police said brake failure was a possible cause. france's former president nicolas sarkozy is to be formally investigated for allegedly accepting illegal funds for his 2007 election campaign from the late libyan leader colonel muammar gaddafi. mr sarkozy denies claims that libyan officials delivered suitcases full of cash to his team during the campaign. fire crews are still fighting a blaze at a hotel and apartment block building in dublin. at the height of the fire, five of the upper floors of the metro hotel were alight. the building was evacuated and no—one was injured. the hotel is near the city's airport, and firefighters from there were called in to help put out the blaze. the white house is expected to announce billions of dollars of tariffs on imported chinese goods later today. president trump is due to sign

a memorandum on trade with china. it would be the latest move by the trump administration to penalise foreign imports, after it targeted steel and aluminium with hefty tariffs earlier this month, raising fears of a global trade war. well, joining me now from shanghai is our china correspondent robin brant. robin, this comes hot off the heels of the chinese leadership earlier this week talking about trade, the fa ct this week talking about trade, the fact that they would reduce tariffs and be open for business. yes... the people's congress promised a further opening up. he promised an end to forcing foreign companies who invest here, forcing them to transfer their technology, and this reaction from the white house is very much centred

on technology, it is centred on ideas, centred on inventions, centred on intellectual property. because the us believes, and i have to say there are countless us businesses here who are hugely to the pathetic to this view, that china not only has been stealing ideas from foreign firms for a very long time, to help develop its own domestic economy, but it is also forcing foreign investors in certain industries, certainly automotive, to go intojoint ventures industries, certainly automotive, to go into joint ventures with domestic firms and also to share their ideas and their intellectual property. in the us frankly has had enough of that. so what we are going to get from the white house overnight is this memorandum. some tariffs, possibly as well as a way of trying to punish the chinese, some restrictions on chinese investment in the united states in key industries that they have been targeting. some have been putting the value of these tariffs at something like $50 billion on 100 different types of chinese goods. what do you think china's reaction

would be to this? well, china does not want a trade war. i don't think frankly the us wants a trade war. what president trump wants, and what much of american business wants is re— ballots. there is a talk a lot about reciprocity. —— rebalance. there has been talk of targeting various us industries, in particular agriculture, mainly in key states that are important politically. also big manufacturers like boeing. the aviation industry in china is huge, and there has been talk of targeting manufacturers like boeing as a way of trying to punish the us, as a way of trying to punish the us, as a way of trying to react against president trump's decision on tariffs. for now, thank you very much indeed. it has been more than six months now since the iraqi prime minister, haider al—abadi, formally declared victory over is in iraq's second city of mosul, where they once

announced their so—called caliphate. the battle came at a great human and economic cost. the un says it will take at least $1 billion to get it up and running again. the people of mosul are slowly trying to put their lives back together. the bbc‘s shaimaa khalil travelled to mosul and met young men and women who are trying to reclaim their city. after yea rs of is after years of is rule, music is backin after years of is rule, music is back in mosul. this man fled his city when so—called islamic state extremists found out he was playing the violin at home. now that he is able to return, he tells me he and other musicians want to rebuild their city, the only way they know how. we are planning to build a

music academy, and to build an orchestra. you want to build an orchestra. you want to build an orchestra in mosul? yes, yes. right now? yes, yes. but some would say mosul needs water, mosul needs electricity, it needs rebuilding. it evidently needs peace, but does it need music? that is what we need 110w. need music? that is what we need now. that is what human beings need now, because all of the community, even we who have a lot of destruction inside of us and ourselves, so we need musical therapy. music therapy may heal some words, but there is no escaping the devastation here. is may have been defeated, but pockets of the militant group still exist in and around the city. mosul is on edge. yet there is a will to move on. it is the exam week. young men, and more crucially women, make their way through what is left of the mosul

university campus. you would have never seen university campus. you would have never seen this when is were in control. like most pupils here, these sisters are three years behind. they have a lot of catching up behind. they have a lot of catching up to do, but they also want to help restore the university library. 0ne of the oldest in the region, now burnt hill and recognition. translation: we volunteered with a number of ngos to collect books from all over iraq in the world. we gathered the books and brought them here to the campus. for the future, whether it is my children, or anyone who asks me, what i did after the city was liberated, i want to be able to say that i am proud of what idid. i able to say that i am proud of what i did. i volunteered, and able to say that i am proud of what i did. ivolunteered, and i able to say that i am proud of what i did. i volunteered, and i helped rebuild mosul. during is rule, we felt like we were in a cage. and now we are free. there is so much to

rebuild in iraq's second city. the infrastructure, trust between the different religious sects and ethnicities, where divisions were exploited by is. and more than anything, the lives shattered by yea rs of anything, the lives shattered by years of violence. stay with us on the briefing. still on the programme: world—class winger to wales coach. ryan giggs makes his international management debut at the china cup. that and more in the sport briefing. let there be no more wars or bloodshed between arabs and israelis. with great regret,

the committee have decided that south africa should be excluded from the 1970 competition. streaking across the sky, the white—hot wreckage from mir drew gasps from onlookers on fiji. you're watching the briefing. 0ur headlines: mark zuckerberg has apologised for breaches of data security at facebook affecting the accounts of 50 million users. the suspect in the texas bombings

has blown himself up, leaving a recorded confession. police say it points to a very "challenged" personal life. britain's prime minister, theresa may, will attend an eu leaders summit in brussels later, where the proposed brexit transitional deal is expected to be approved. the european council summit will focus on the progress of negotiations, and its leaders will put forward their own vision of the future relationship between the eu and the uk. joining me now is daniel gros, director of the centre for european policy studies. thank you for being on the programme. to a degree, is this about rubberstamping, those detailed between michel barnier and david davis earlier this week? yes. there

isa davis earlier this week? yes. there is a text now so leaders can say they broadly agree with it. but how can the sticking points be dealt with? that is the question, including the irish question, which might be one of the key problems for both sides. it is seen as one of the key hurdles to overcome. it is not clear how that will be achieved, especially with the irish leadership as well wondering what it means for them. exactly, that is a problem because we know there is a logical conundrum, either there is a border between the two ireland's or in the sea. between the two ireland's or in the sea. so we are waiting for proposals from theresa may to solve this problem, or at least mitigate it. they are waiting for ideas from

london. from a practical perspective, presumably, that has got to be resolved before march of next year when we do officially the european union and the so—called transition phase kicks in, lasting until december, 2020. exactly. that is the idea. in brussels, they learn from the mistake a few weeks ago, using legal language to say they might have to be border checks between britain and the northern irish. but for the time being, they have learnt this mistake, and will no longer talk about this. they would just wait for something to be proposed and then we will see. would just wait for something to be proposed and then we will seem sounds like we will all be waiting for a while longer. thank you, for now, daniel. now it's time to get all the latest

from the bbc sports centre. coming up, the houston rockets continued their charge to the nba play—offs. serena williams is knocked out of the miami 0pen. and why you should be careful in cricket where you stand. we start with cricket. zimbabwe zimbabwe have the power to book their place in the world cup later on thursday. they just have to beat the united arab emirates in harare. the former manchester united forward, ryan giggs, with more than $1000 for the club, is one of the greatest footballers of generation. —— 1000 goals. he says this could be the proudest moment of his career so far. coming here and winning the

first game, a tournament, still with that winning mentality, but also, it isa that winning mentality, but also, it is a process as well. it is notjust short—term, it is long—term. it is a lwa ys short—term, it is long—term. it is always nice to win games, not only for myself and the staff, but the players. it gives them confidence. the houston rockets, including james, they are looking to extend their lead at the top of the western conference. they they have a 6—game winning streak and are taking on detroit. the pelicans want to climb higher than fourth in the west. they eat dallas last time 115—15. the top score was 37 points. —— 105. in case you missed it, west indies cricket have had a sigh of relief were beating scotland by five runs in

harare as rain ended the match early. they got off to a good start. there was a century partnership. the west indies could only manage an underwhelming 198 scotland replied. ritchie was given out co ntroversially. ritchie was given out controversially. the rain started and the scots were five runs short. serena williams is out of the miami 0pen after the first hurdle. she was given a wild card and had a shock defeat against naomi. she will now face elina svitolina from ukraine. and finally, a particular moment for the west indies. scotland has done well around the world on social media with this one. samuels was

batting with such ferocity. look at this. his opponent went down after being hit in the back. 0uch indeed. you can get all of the latest sport on our website. from me, that is the latest sport briefing on thursday. australian teacher, eddie woo, has won fans worldwide with his high—energy maths lessons posted online. mr woo recently won australia's local hero award and was a finalist for the global teacher prize. he's been explaining his formula for infectious lessons to the bbc in sydney. my name is eddie woo, i'm the head teacher of mathematics at cherrybrook technology high school in sydney, australia. "i am going to put on,

to finish my definition, i am going to put on two more words..." when i started making these videos, i only did it with one student in mind. he was very sick so he was missing a lot of class. for this to have gotten around the country, all around the world, for me, it isjust endlessly amazing. i get comments every now and again saying ‘who is this asian guy and what is that accent coming out of his mouth?" because they cannot pick the accent. congratulations. what i am really aiming for, i guess, is to help people think about mathematics as not a scary subject, not something that is really challenging,

"only for special people," but i want people to see it is accessible, understandable. i want to get that sense of sense of wonder of students, that human beings have, so when they see something they think "how does this happen?" there is this famous saying, "it is magic until you understand it, and thereafter, it's mathematics." "how many cards did you get that matched on both sides? i have heard people who got eight and eight, four and four, i've heard a seven and seven, a six and six. it opens up a way to see things in a new way you never could have imagined before. just go outside and pick up a flower, look at the pattern of seeds that's there, that spiral, that shape. there is an unmistakable pattern which can be explained mathematically. mathematics is there all around us if only we have eyes to see it. i encourage everyone to look around them and see the patterns around them and wonder, but don't stop there — ask why, go and look up a reason

and then you yourself can become a mathematician. there is hope for all of us, according to eddie woo. did you have an inspirational teacher? let us know on line. stay with me on bbc news. i'll be back with the business briefing in just a few moments. we will be talking about facebook in the coming programme. there is a light on his apology for the data breaches on our website. —— a lot. that is in the business briefing,

which is coming up injust a few minutes. we will see you very soon. hello there. temperatures have been slowly recovering over the last couple of days after that mini beast from the east brought us that disruptive snow. and in fact, as we head out into thursday, a milder start and generally quite a mild afternoon. with some good spells of sunshine, it really will quite springlike. the atlantic has come back to life, now feeding in cloud and this milder air. we've seen the back of that cold easterly wind. you can see the air mass chart here, the orange colours which will be moving in, certainly for thursday. something a little bit fresher pushing in behind for the end of the week, for friday. mild air never too far away. in fact, at the weekend, given some sunshine, should be quite pleasant. as we head through the overnight period into early thursday, we'll see some damp weather down the east of the country, affecting east anglia and the south—east. but elsewhere, it's going to be largely dry. variable amounts of cloud. a bit more of a breeze further west. but it's going to be a much milder start you'll notice to thursday. most places starting off 4—7 degrees. just one or two pockets of frost perhaps in some very sheltered rural locations, south—west england,

maybe north—east scotland. but through the day on thursday, it's looking pretty good. we'll lose the cloud from the eastern side of england. some good sunny spells around. we'll start to see a change in northern ireland and western scotland. increasing wind here, gusting to 45mph, outbreaks of rain. but elsewhere, a lovely day in store. temperatures around 12, 13, maybe 1a celsius in the warmest spots. on thursday night, that rain band will spread across the country, eventually clear the eastern of the country for friday. so another fairly good—looking day. some sunny spells around. showers across the north—west. winter on the hills. maybe a toucher cooler than what we saw on thursday. now into the weekend itself, it isn't looking too bad. a typical early spring weekend, really. sunshine and showers, variable amounts of cloud. and it will be generally quite mild, particularly where we get the sunshine. this is how we start saturday morning off, on a rather cloudy note across central, southern and eastern parts of the country. the cloud may hang on in the south, the odd spit and spot of rain. but skies will brighten up, particularly further north and west. a few showers running into scotland and northern ireland, and winter on the hills. given some sunshine,

temperatures around 11 celsius. sunday is looking like being the better day of the weekend. more widespread sunny spells around. just a few showers again across the north and west of the country. probably the best of the sunshine, in fact, across the east. it will feel a little bit milder too, top temperatures around 13 celsius. this is business briefing, i'm sally bundock. "if we can't protect your data, we don't deserve to serve you". mark zuckerberg promises more safeguards for facebook users, but how much damage has already been done? plus: trading blows with beijing. the white house vows to hit back at china over intellectual property theft. billions of dollars of tariffs could be slapped on chinese goods later today. and on the markets, the us raises interest rates. and there is more to come.
