On thursday, he put forward a series of measures to try to tackle the problem. The president said there was widespread public support for stricter rules, despite the efforts of the gun lobby. Gun violence in this country is an epidemic. Let me say it again gun violence in this country is an epidemic and its an international embarrassment. Applause we want to rein in the proliferation of so called ghost guns. These are guns that are home made. Built from a kit. And include directions on how to finish the firearm. You can go buy the kit. They have no serial numbers, so when they show up at a crime scene, they cant be traced. And the buyers arent required to pass a Background Check to by the kit to make the gun. Well, within hours of president bidens announcement on gun curbs, a man was killed in the latest Shooting Spree at a business site. Heres our washington correspondent, lebo diseko. This is in texas today, there has been a mass shooting, one person died, four people have been injured. Yesterday in South Carolina there were five people who were killed, including the shooter himself, he shot himself there. And obviously in the past few weeks we have had really, quite a shocking mass shootings, both in georgia and south colorado. When you look at the statistics, the number of mass students here in the United States, it is estimated there is about one a day on average mouse shootings. Is estimated there have been 11,000 gun deaths this year alone. Mass shootings. Lebo diseko there. A medical expert has told the George Floyd Murder trial in minneapolis that the 46 year old died from a lack of oxygen, due to the way he was restrained. Former us police officer, derek chauvin, was filmed kneeling on George Floyds neck during his arrest last may. He denies the charge of murder. This is what the expert, dr martin tobin, was asked in court by the special assistant attorney general. Have you formed an opinion, to a reasonable degree of medical certainty, on the cause of mr floyds death . Yes, i have. Would you please tell the jury what that opinion or opinions are . Yes. Yes, mr floyd died from a low level of oxygen. And this caused damage to his brain that we see and it also caused a Pea Arrhythmia that caused his heart to stop. Well, dr tobin also rejected the suggestion that the drug fentanyl was in any way responsible for George Floyds death. Youre familiar with the way people die from fentanyl . Yes, very. Do they or do they not go into a coma before they die from a fenta nyl overdose . Yes, they will. Was mr floyd ever in a coma . No. Thank you, dr tobin. 0k. 0ur correspondent, larry madowo, has been following the trial in minneapolis. Dr tobins testimony today has left the defences case looking weaker than probably it has at any point in the last two weeks. His testimony that george floyd died from oxygen deficiency, which led to his brain to stop, was so significant because its at the centre what the prosecution is saying here. The three reasons for that, he says, is because he was lying flat on the concrete, he was handcuffed behind his back, and he had several officers kneeling on him. He also calculated that from the moment george floyd stopped breathing, there were three minutes and 27 seconds when the neck restraint continued. So dr tobin, all through this testimony, was captivating, he was masterful and his testimony, therefore, is potentially devastating to the case because the jury paid attention and took notes.

The warning comes after weeks of increased fighting between Ukrainian Government forces and russian backed rebels. America says its deeply concerned that russia has deployed more troops on its border with ukraine than at any time since 2014, when Russian Forces seized control of crimea. Mark lobel reports. Ukrainian troops in the countrys tumultuous east received this show of solidarity from their president following weeks of increased fighting there.

Russian backed rebels report one of their fighters was killed this week when ukrainian troops fired 14 mortar bombs at a village on the outskirts of the city of donetsk.

Heres our chief environment correspondent, justin rowlatt. It is one of the most remote regions on earth, the vastness of the pacific ocean. But more than two miles beneath the surface lie incredible reserves of the metals needed to make electric vehicle batteries. So this is what the Mining Companies are after. This is a poly metallic nodule. Its a kind of nugget of crucial battery metals, so in here youve got cobalt, nickel, copper, manganese and there are hundreds of millions of these lying on the deep sea floor in some areas of ocean. We can dramatically reduce our environmental and social impact. The Mining Companies say Sourcing Metals from the deep ocean has a lower Environmental Impact than Mining Metals on land. And they just sit there like golf balls on a driving range. So we dont have to drill or blast to find them. Also, they happen to sit in an environment where there are no forests, no plants. Its a no brainer where we should be getting our metals from. Environmental campaigners disagree. They say mining will destroy fragile ecosystems that have developed over hundreds of millions of years. Petrol. With the climate and biodiversity challenges facing this planet, Deep Sea Mining would be another scandalous threat to our oceans. Petrol. 0r electric. Bmw, google, samsung and volvo trucks announced they would not be using any metals sourced from the deep ocean in their products. At the Natural History museum, zoologist Adrian Glover studies the creatures that live on the deep ocean floor. Of course, James Cameron was inspired by deep sea animals for all of his movies. He says the impact of mining will be profound. It means humanity faces a difficult decision. It will be a dramatic shift in the ecology of that environment. And thats something that you just have to accept. Some areas of the planet will have to be impacted if humans are going to move forward in a zero carbon future. The decision about whether to allow mining will be taken by the un body that controls exploitation of the deep ocean. But, as sales of Electric Vehicles increase, pressure to allow mining in The Deep Oceans is also likely to grow. Justin rowlatt, bbc news. Now, time for the latest sports news from the bbc sports centre. Hello im Austin Halewood with your latest sports news. We start with golf because the masters is in full swing at augusta. With the tournament back in its traditional spring home on the calendar, Englands Justin Rose is the man to catch after the first round. The two time runner up had the round of the day at augusta, shooting a 7 under par 65 to leave him 4 shots clear at the top of the leaderboard. He was 2 over par through 7 holes but 7 birdies and an eagle have taken him to the top. You cant win the Golf Tournament today, even with a 65, you cant win it today, you can only probably lose it today. I was very aware today being a couple over from seven, i didnt hit the panic button yet but i resetjust prior to that and thought if i can get myself back around even park, they will be a good days work. Even par. Its only five months since dustinjohnson won last year and he began the defence of his title with a 2 over par round of 74, which included this chip for a birdie at the 11th. Johnsons looking to become the first player since tiger woods in 2002 to win back to back masters. If he doesnt, hell be the shortest reigning champion in history. So confirmation of the leaderboard after round 1. Rose at the top on 7 under, with Hideki Matsuyama and brian harman both 4 shots back on three under. The former champion patrick reed is in a group of players who are a further shot back on 2 under par. Now to football and its been a busy night in the Europa League with the first leg matches of all four quarter finals. And Manchester United have taken a big step towards the last four after a 2 nil win in spain against granada where Marcus Rashford with the help of var put the english side in front after half an hour. Bruno fernandes then scored a penalty in stoppage time to give united a two goal cushion to take back to old trafford for next weeks 2nd leg. It looked like it was going to be a 1 0, but we gladly take the second goal of course. It is so vital away from home. We have created a good Starting Point for the next weeks game for ourselves. In the nights other games, roma came from behind to win 2 1 at ajax where roger ibanez scored the winner three minutes from time. And Gerard Moreno scored the only goal of the game a penalty as villarreal won at dinamo zagreb. And arsenal were held to a 1 all draw at home, after a 94th minute equaliser from slavia prague. The 2nd legs of all those ties take place next thursday. And the french open will start a week later than scheduled, itll run from the 30th may to the 13th ofjune. Tournament organisers at Roland Garros say they want the largest number of fans to be able to attend,and with france in a Third National lockdown, moving the championships will give them the best possible chance. Now this will impact on the Grass Court Season in the build up to wimbledon. The lta say they are looking at the implications for their events and might make changes to the calendar as well. Back with the business in five minutes. See you soon, goodbye. Hello. Although thursday was a little less cold for many, friday plunges us back into the arctic air. In fact, we will stay with the colder air again into the weekend for many. There is certainly a chance of those snow showers and possibly wet and windy weather in the south, we will come to that in a moment. This is the Weather Front ushering that Cold Air Southwards and that will push to most parts by the end of the day today. With it the brisk wind which through the night has reached severe gale force in the north, slowly easing away, but cold air means widespread frost first thing and a risk of ice because here the showers have been coming through notjust for scotland but for Northern Ireland, some northern fringes of england and wales as well. That Weather Front further south is a slow moving affair. Still windy, although they are easing off, the great risk of snow piling up is in Northern Scotland but the showers will come through thick and fast during the day. They could fall as rain, sleet, snow, hail, rumbles of thunder. Further south we will have a Weather Front becoming slow moving. Could be sleety on high ground with this Weather System as the cold air digs in but we will see crisp sunshine across the northern half of the uk through the day ahead and brightness and sunshine to the south of the Weather Front affording us perhaps 11 or 12 degrees but if you are stuck under the cloud all day, seven and eight is more likely. A transition day, one that feels wintry for many. The big question for the weekend is this area of cloud and rain, possible hill snow and a brisk north easterly wind during the course of saturday and into sunday. There is still quite a bit of uncertainty as to how far north that will come but as i say it could be a spell of wet weather. A brisk north east wind makes it feel cold and that could turn to snow over the hills. Further north again the crisp sunshine continues but even with the sunshine it will be cold with the risk of sleet and snow showers just about anywhere because we are into the arctic air. The same is true through Saturday Night and sunday that slowly works out of the way but then we have arctic air right across the uk and perhaps something more organised coming into the north west later on sunday. Plenty of detail to fill in and if you have plans stay tuned to the forecast. As ever, the forecast and the warnings are online. Hello.
