A jury in los angeles has found in favour of elon musk in a libel case involving a british cave explorer. The two had engaged in a public argument about how to rescue children trapped in a cave in thailand. In a tweet, mr musk called the caver pedo guy a phrase he argued was not meant literally. Our Technology Reporter dave lee reports from los angeles. Elon musk entered court on friday for the fourth and now final day of this trial. What has surely been the most intense, not to mention expensive examination ever of a single tweet. How many of you . That tweet, sent in july 2018, came in the midst of the miraculous rescue of 12 thai boys and their football coach from a flooded cave. Vernon unsworth, a british man who live nearby, was instrumental in advising that effort. Elon musk also traveled to the region, with a specially designed mini submarine. In a tv interview mr unsworth called it a pr stunt, calling mr musk to snap back, using the phrase pedo guy. He later deleted the tweet but Vernon Unsworth sued him for defamation, saying he had wrongly been accused of paedophilia. Elon musk was describing court as a billionaire bully, a man who dropped a nuclear bomb into the life of Vernon Unsworth. But the jury said the tweet was an insult but not an accusation, a view which could set a precedent when it comes to libel cases involving social media. This verdict sends a signal, and one signal only, that you can make any accusation you want to, as vile as it may be, as damaging at it may be, as untrue as it may be, and someone can get away with it. The only thing im going to say is, the jury got this right, and we dont have any further comment at this time. How is mr musk . Everyone is well. Thank you. Ultimately mr unsworths lawyers were unable to prove that his life had been sufficiently negatively impacted. Indeed in the days after the tweet, the defence argued mr unsworth was the focus of celebration and praise, not suspicion. It means that while ill judged tweets may have cost mr musk millions of dollars in the past, it was not to be the case this time. I accept the jury verdict, take it on the chin, and move on. Saudi arabias king has described the killings of three people at a Us Military Base carried out by a saudi citizen as a heinous crime.

The involvement of a Saudi National has raised questions about the gunmans motive. Investigators are looking into whether the shooting was terror related. The government of saudi arabia needs to make things better for these victims. And i think that they will owe a debt here, given that this was one of their individuals.

The leading candidates in the uks upcoming general election have gone head to head in a televised bbc debate. Borisjohnson and Jeremy Corbyn have been making their final pitches to voters, ahead of next thursdays general election. Their policies on brexit and the National Health service have been a focus throughout the campaign as have issues of trust and character. Our Political Editor, Laura Kuenssberg watched the exchanges. Whose night would it be . The contender, with the crowd, or the man who called this election, who wants to keep his job . Both arriving for a 60 minutes that could make or break a bid to win. The audience, not the rivals, in charge. Fanfare. Starting with a blast against both of them from their former party leaders. Is sirjohn majors recent intervention worrying to you, mrjohnson . And is mr blairs recent intervention worrying to you, mr corbyn . Or are theyjust a couple of old has beens . Unlike mr major, i lead a party now that is totally united. All 630 plus conservative candidates at this election actually back my deal. Totally united because you got rid of anybody who did not agree with you. No, we have a very, very Broad Spectrum of views in our party. I urge them to think for a moment think for a moment at the reality of what nine years of austerity has done to the people of this country. Then, of course, brexit the question of our times. Can you guarantee that it will happen next year . We will, within three months, negotiate a leave agreement with the European Union that will protect trade and jobs and the Peace Process in Northern Ireland. And put that alongside remain in a referendum within six months, and that will be the end of the matter. Everybody on the labour front bench is campaigning to remain, apart from mr corbyn who is neutral on the matter, who is going to secure this deal . How can you get a deal from brussels for brexit if you dont actually believe in it . That is the mystery. What he will do is walk out of a relationship with the eu into a relationship with nobody and that is where the chaos will come. What is your answer to that, Boris Johnson . Im afraid that shows a slight ignorance of the reality. And what of labour claims that the torys brexit deal would hurt Northern Ireland . I do find it slightly curious, to say the least, nick, to be lectured about the union between Great Britain and Northern Ireland by a man who all his life, political life, has campaigned to break up that union and actually supported for four decades the ira in their campaign, violently, to destroy it. Applause. What i have done is always wanted to see a Peace Process in Northern Ireland, and that is exactly what we have got and thank you to the Labour Government that negotiated it. Applause. And then one of the biggest questions this time who and what to believe . What punishment do you think is appropriate for elected politicians who lie during political campaigns . They should be made to go on their knees, down, through the chamber of the house of commons, scourging themselves with copies of their offending documents which claim to prove one thing and actually prove something quite different. Jeremy corbyn . When people paint slogans on the side of a bus that are totally unsustainable. Applause. Perhaps it is time that we did have an independent monitoring of what goes on. Brief response, mr johnson . Actually, if you look at the numbers that we put on the side of the bus, look at the gross figure we paid to the eu, the number is going up. After a torrid campaign, no huge ruck, even handshakes at the end but the hard won results next week will be your decision, not a gentlemans agreement. And lauras been giving us the reaction to the debate and what it could mean for next weeks vote. Tonight we basically saw the two main rivals on their best behaviour, really. Neither of them were going at it hammer and tongs, neither wanted to give themselves the risk of crashing and burning. And in a way i think they were trying to appeal to their core voters, those people who have already made up their minds. And therefore we should maybe not be surprised that it did not feel like there was a big Game Changing moment where either Boris Johnson dropped the ball orJeremy Corbyn managed to land a new goal at the back of the net. And if we think of the broad context of this campaign with only six days to go, broadly speaking, look at the polls with a big pinch of salt, the tories are consistently ahead. The difference is in by how much. Labour are consistently trailing them. Therefore tonight it was borisjohnsons side who are deeply nervous that something terrible may go wrong. It did not really, nothing that would change their standing in the polls. And forJeremy Corbyn this was one of his last chances to really cause an upset or really start narrowing the gap, and i dont think for labour we saw a sign tonight of anything that could really spark up their side. But i think their core voters, people who are die hard red or blue would have watched their man and felt reassured of the decision they have already made. But they are not really in charge, it is the floating voters and are unsure of which way to go. Our Political EditorLaura Kuenssberg there.

A mega fire raging to the north of sydney is so bad, officials in australia are warning it cant be extinguished at least for now. Residents are being told they should leave immediately if they arent able to defend their property from the approaching flames. Four major areas along the coast of New South Wales are being affected. Two fires are threatening homes near sydney, and others are burning towards major population centres in the south and central areas. Abc correspondent Antonette Collins is at the oaks, a town on sydneys south western outskirts. She gave us this update. Well, look, here, its been a hive of activity with trucks and water bombers flowing past and in and out all morning and overnight as crews try to take advantage of better conditions overnight and this morning, so they are really focusing on those back burning efforts. It is not about extinguishing the fire, if you like, it is about managing the fire and controlling it so that it burns in on itself or to establish blacked out areas so it doesnt encroach on homes as we progress into the afternoon and into this evening. Conditions here are going to reach around 3a degrees today, later this afternoon, and those winds are expected to pick up. This is one of the two major fires currently burning out of control around sydney. The other, as you mentioned, is to sydneys north, where three major fires have effectively combined into a mega fire. The threat there is the impact, if the winds come through, projects that fire into the east, to the coast there, where there are a significant amount of properties, so crews this morning have been focusing their efforts on trying to get on top of things as much as possible before conditions worsen later today. And how much can fire crews and the authorities do to stop the progress of these fires, especially in light of what you are saying about it moving towards more populated areas, and, indeed, toward sydney . Thats right, i mean, that is the concern for the crews here. There have been some ember attacks and spotting from this particular fire, 5km ahead to the nearby town of camden, which is a major population centre, so they have been working to the north, to the east, to the west, and to the south, to really try to stop that fire spreading across those containment lines. That is pretty much all they can do. They are using water bombers but they really have to attack the fire with fire in a bid to really try to limit the damage that it can cause. But, of course, depending on how those winds flow, this area in particular, there is a lot of gullies so the nature of the Wind Movement is very unpredictable and because of that changing wind, that actually causes more pr
