a very warm welcome to bbc news, broadcasting to viewers in north america through to the semi—finals in dubai. and around the globe. my name's mike embley. our top stories: after the collapse of the us—north korea summit, president trump points the finger, hello and welcome to saying pyongyang wanted the programme where we start all sanctions lifted — with the track cycling world championships in poland something he could not accept. and it was a good day for the australians as they picked you always have to be up three of the four prepared to walk. gold medals on offer. that included the men's team pursuit i could have signed an agreement today, and then you people in which the quartet of leigh howard, sam welsford, would have said, "oh, what a terrible deal, kelland o'brien and alex porter set what a terrible thing he did." no, you have to be prepared to walk. a new world record as they beat but that's been flatly great brtitain in the final. contradicted by north korea. they clocked 3 minutes, it says it was only asking for some 48.012 seconds, breaking the record of the sanctions to be lifted. they set at last year's commwealth games, and laying down translation: if the united states a marker ahead of next removes partial sanctions, we will permanently and completely dismantle all the nuclear material year's olympics in tokyo. production facilities in the yongbyon area. we knew coming in had good form, as the so—called islamic state extremists face defeat on the ground doing good timings in practice. but to be able to qualify after the fastest i am after what happened

with the new zealander. we wanted to bring the world title back to australia and that if we executed everything we would challenge for the world record but not by that much. there was a second gold medal later in the day for sam welsford as he raced to individual success in the men's scratch race, adding the world title to the gold medal that he won on home territory in the commonwealth games last year. australia's third gold of the day came in the women's team pursuit. as in the men's event, the aussies were up against great britain in the final. the quartet of ashlee ankudinoff, georgia baker, amy cure and annette edmondson nearly blew it when they split in the final two laps but edged it in the end by 2/ioths of a second. great britain had to settle for silver, just as they did 12 months ago. back home, we ran a quicker time and i had better legs, much better legs.

but not the last few days, i don't know why, it is not like i am feeling unwell and i feel know why, it is not like i am feeling unwell and ifeel partly responsible because back home we went quicker and it is a bit disappointing, i guess. it was the dutchman matthijs buchli who prevented an australian clean sweep for the day. he won the men's keirin to claim his second gold medal of the championships, 2a hours after helping the netherlands to victory in the men's team sprint. valencia will face holders barcelona in may's copa del rey final after they beat real betis 3—2 on aggregate in their semi final. the tie was level at 2—2 from the opening match in andalusia, and rodrigo made it a 1—0 win for the hosts in the second leg at the mestalla when he scored shortly after half time. valencia will ghead back to rral betis‘s ground in seville for the final, which is being staged there on 25th may. in other football news, the real madrid captain sergio ramos has been banned for two european games "for clearly receiving a yellow card on purpose". ramos fouled kasper dolberg of ajax

during the ist leg of their recent champions league last 16 tie which madrid won 2—1. that means he'd miss the 2nd leg but would be available for the quarter—finals. uefa says ramos got himself booked deliberately, and they've extended his ban to two games, which means he will miss the ist leg of the quarter—final, if real madrid qualify. claudio ranieri has been sacked by the english premier league side fulham after only 17 games in charge. the italian, who won the premier league title with leicester city in 2016, onlyjoined fulham in november. but after wednesday's defeat at southampton, they're 19th in the league, and last month fulham were knocked out of the fa cup by 4th tier side oldham athletic. the club's former captain scott parker has been named caretaker manager. hosts new zealand are surging ahead on day 2 of the first test against bangladesh in hamilton thanks to a massive opening stand byjeet raval and tom latham. the pair have added a third highest

partnership for new zealand for the opening wicket. in response to bangladesh's total of 234 in what is the first of three test matches. elsewhere, afghanistan beat ireland by 5 wickets in the first one—day international of their five—match series in india. the irish were skittled out forjust 161, of which paul stirling made 89. in reply, gulbadin naib top—scored with 46 as afghanistan reached their target with more than five overs to spare. some of the world's leading rugby players have expressed concern over new proposals to revamp the international calendar. the sport's world governing body reportedly want to introduce a 12—team "world league" starting in 2020. but the world player of the year, ireland's johnny sexton, and the england captain 0wen farrell have already voiced their opposition to the plan. they claim the idea's "out of touch" and harmful to player welfare. patrick gearey reports.

this is what it takes to play international rugby union. it tugs at the emotional and physical extremes. the governing body wants to ta ke extremes. the governing body wants to take it on a world tour, 12 nations taking each other on during the year. but the rugby selling point is also breaking point. before the plans have been formally announced, the body has raised body about its safety. if it continues down this path, and that came out loud and clear from a0 players we spoke to, it is already at breaking point and we continue to fire there is dangerfor the point and we continue to fire there is danger for the players and fall quys is danger for the players and fall guys wanting to play the game. the rugby association also questions the

exclusion of pacific island teams. there are fears are keeping them out of any competition could drive evermore islanders to represent nations on distant shores. players wa nt to nations on distant shores. players want to play against the best. if there is a ceiling, smaller nations should play in the first place. we are at crossroads at one we're familiar with as pacific islanders. world rugby released a statement... in other words, nothing has been decided and sources at the 0rganisation had insisted pacific islanders are still a possibility. it may take some manoeuvring to get

this one out of what has become a faintly major scrum. tennis and roger federer‘s through to the semi—finals of the dubai championships. federere the number 2 seed, remains on course to claim the 100th atp tour title of his career after beating the world number 35, hungary's marton fucsovics, to reach the last four. federer won the first set on a tie—break and the second 6—a, to seal his place in the semi—finals. iam happy i am happy it is over. we had a couple of rain delays, dusty wins. he played well. saved two set points. it got me going. the day session went longer so it was an extra weight. federer will now face the number six seed from croatia borna coric. he had to come from a set down to beat georgia's nikoloz basilashvili with the deciding set going to a tie—break. after nearly two and half hours, coric sealed his his place in the last four.

also through to the semi—finals is stefanos tsitsipas, but the number 5 seed from greece needed three sets to see off this man, hubert hurkatch, the pole who knocked out the top seed kei nishkori. after trading tie—break sets, tsitsipas raced through the decider for the loss ofjust one game to reach the semi—finals and he remains on course for back—to—back tour titles following his win in marseille last week. and the greek now faces gael monfils, another player who's aiming for a second tour title of the year after winning the rotterdam 0pen last month. the frenchman was taken to three sets by the lithuanian qualifier ricardas berankis, who's ranked 113 in the world but won the deciding set 6—2, to reach the last four. it's understood that bryce harper and the philadelphia phillies have agreed to the largest deal in major league baseball history worth $330 million over 13 years. the deal for the 26 year old all star outfielder is subject to a medical. he was the 2015 national league mvp

and made six all—star teams in seven big league seasons with the washington nationals and the deal will top the $325 million, 13—year agreement outfielder giancarlo stanton reached before the 2015 season with the miami marlins. six games taking place in the nba. the cavaliers are bottom. the knicks above them. 6a—61 the cavaliers lead. 0rlando after losing one point late against ime are up in the fourth quarter of that one. everything else on the website. until next time, bye—bye.

well, we're just into march and the weather has turned a little bit colder, after that very warm spell in february. now, the atlantic is looking very turbulent at the moment, look at those clouds swirling around. these are low pressure weather systems and here are weatherfronts, one here — in fact, there's multiple weather fronts around. there's another one coming in from the south as well. all of that is heading in our direction and as promised, the coming days will be very changeable. some days will be wetter than others, but we'll all experience that changeable weather. so first thing in the morning, pretty mild, nine degrees in london first thing on friday. around five degrees expected in aberdeen and in edinburgh, a really murky, misty sort of start to the day, with a bit of drizzle, but it's not all bad because some of us on friday will actually get at least little bit of sunshine, particularly across the western areas, so cardiff, birmingham, the north—west of england, for example, around liverpool, could get some sunshine. the further east you are, the cloudier it'll be. now, a weather front is approaching, you saw the satellite image there. here's the first one, it moves

into northern ireland friday night, also the south—west of england and eventually wales, and ither parts of the country will get that rain in the early hours of saturday. so early on saturday, again, a lot of mild weather, when we get cloud and weather systems coming off the atlantic, it does tend to be quite mild. so the weekend is looking very blustery across many parts of the uk. we will see a low pressure moving off the atlantic. here it is, friday night into saturday, as it moves in, a lot of isobars there, those white lines, those pressure lines, that basically means very strong winds. so the low pressure comes across ireland, the rain reaches belfast eventually. ahead of it for a time in the morning, it could actually be quite bright. and one place where we could keep the dry weather for most of the day and it may actually be really decent, that's london and norwich, temperatures here up to around 1a or 15 degrees. however, the weather will turn in the south because one this area of low pressure moves away, another one further south swings into southern areas of the country,

so here we are expecting some pretty wet weather for cornwall, devon, parts of wales, the midlands, southern counties, east anglia and the south—east, so many of us in southern parts of the uk will need our brollies on sunday. it's likely to be quite windy too. but northern areas, aberdeen there enjoying some sunshine on sunday, with temperatures of around about 10 celsius. so it is all change, that warm weather we had in february will soon be a distant memory as this much cooler, showery weather continues into next week and it may last for quite some time. that is the latest.
