premature, that's for sure. i really don't know what my time is. i could probably stay until i'm a0 if i want to but i don't think i'm going to do that. i could stay one or two years, but in two years time will i still have the excitement that i have now going into another season? i really can't tell you. after barely playing for the past three years, tiger woods will start this weekend's bay hill championship as one of the favourites. in his prime, woods won this tournament eight times but it is now nearly five years since he last picked up silverware. but the 1a—time major winner finished joint second in the valspar championship a few days ago. it's led to him being one of the favourites for the arnold palmer invitional and second favourite with the bookmakers for the masters in augusta next month. for me to go from not knowing whether i'll ever be able to play the game again to, i might be able to play it may be at the tou level,

to play it may be at the tou level, to actually i might be able to make a couple of cuts or might be able to possibly get myself into the mix. 0h, possibly get myself into the mix. oh, i'm in the mix! there's a there isa oh, i'm in the mix! there's a there is a process and evolution to it. it's been quick but still i have to say just enjoy it's been quick but still i have to sayjust enjoy all of it's been quick but still i have to say just enjoy all of this because it's been quick but still i have to sayjust enjoy all of this because i at one point wasn't... didn't ever think of playing out here. cricket, and india beat bangladesh by 17 runs in the latest match of the tri—nations t20 series in sri lanka. india batted first and made 176 for three with captain rohit sharma posting 89 from 61 deliveries. bangladesh struggled to keep up with the run rate in their reply, with only musfiqur rahman, who remained unbeaten on 72, providing sustained resistance. india will play either bangladesh or sri lanka in sunday's final. my my photo and... both of us bowled

well. those eight overs turned out well. those eight overs turned out well for us. if we could play to our potential and play to our strengths and get another good day definitely we could win the tournament in the finals and we'll be able to get the trophy as well. that's it for now. thanks forjoining us. hello there. 1a degrees yesterday in london. a0mm of rain in northern ireland. those were the contrasts we had. together with the rain in the west, we also had some quite strong winds as well. now, the rain is going to be moving, it starts as rain over the next few days but then it turns colder. we get an easterly wind just in time for the weekend. that's when it really feels cold.

we may get some snow showers, mainly for england and wales. this is where we are, though, at the moment. this weather front here is moving its way a bit further north and east across the uk. stronger winds ahead of that weather front, lighter winds developing further south, and we should get some sunshine as well. still some rain, though, for northern ireland on thursday morning and that moves through the midlands away from the south—east of england, heading towards southern scotland and northern england. perhaps a bit of wintriness over the mountains. sunshine to the south and we get some sharp showers. possibly thundery. 12 or 13 degrees. north of that band of rain it is quite a bit colder, but the cold day is yet to arrive. we'll see that rain turn to sleet and snow over the higher ground overnight in scotland. still some rain for the north—east of england and we could still see some sharp bands of showers pushing up across england and wales towards northern ireland. again, no frost i think early on friday morning. that wet weather in scotland increasingly wintry over the high ground. some heavy, perhaps thundery showers in a band moving across northern england, running into the back of that wet weather and bringing

more rain to northern ireland. heavy showers again developing to the south where we'll get sunshine. contrasting temperatures again north and south across the uk. over the weekend, we all get into the same boat. high pressure blocking things off across scandinavia and around it we pick up an easterly wind. there will be a significant windchill as well, especially across england and wales, where we'll have the strongest of the wind. perhaps not too many snow showers, actually, on saturday. there could be some on friday night, but most places will be dry on saturday. you will notice, however, the temperatures significantly lower. remember 12 or 13, perhaps, across the south on friday. four or five at best, and further north one or two celsius. that area of high pressure still around the northern part of the uk on saturday. stronger winds to the south. we could get as spell of snow overnight and especially near channel, the southernmost counties of england. that pulls through and then we'll probably find a few more snow showers, again more likely

across england and wales. most of scotland and northern ireland will be dry and it is not quite as windy here but it's still going to be cold on sunday, colder than it should be. welcome to bbc news, broadcasting to viewers in north america and around the globe. my name is nkem ifejika. our top stories — the usjoins britain in blaming russia for last week's nerve agent attack. at the united nations, its ambassador demands action. the credibility of this council will not survive if we fail to hold russia accountable. moscow, again, denies any involvement in the attack. translation: we demand that material proof be provided over the allegedly found russian trace in this high—resonance event. a month after the floida school
