as a senior administration official says there has been no fundamental change in the dynamic after that call between presidents biden and putin. the us says it is unclear whether russia is interested in pursuing its goals through a diplomatic solution rather than through the use of force. so president biden was blunt about his intention to impose punishing economic sanctions — "swift and severe costs", he called them — if russia does further invade ukraine. and after the call, the kremlin�*s top foreign policy adviser said, "hysteria has reached its peak." now, as america believe that president putin is in a position to order an invasion any day now, they're warning about the possibility of a manufactured attack on russian forces that could be blamed on ukrainians and then used as a trigger for military action. new details about what the us calls a false flag operation were discussed in an emergency meeting in the white house situation room two nights ago. they say it could involve russian operatives with

explosives carrying out attacks on russian forces that would then be used as a pretext for an invasion of ukraine. so tonight, the us says it has not ruled out the possibility of further talks, but they are now also planning for a worst—case scenario. a dozen nations including the uk have told their citizens to leave ukraine. our correspondent paul adams has been speaking to some of those affected.

different information and now the best friend for enemies, the panic in our country. and all this information helps only for panic, it doesn't help us. russia's war games in belarus are now under way. this, american officials warn, is how an assault on ukraine could begin. moscow still says it has no plans to invade. joe biden and vladimir putin spent an hour on the phone tonight. mr biden told the russian leader that if he launches a further invasion of ukraine, the west and its allies will impose swift and decisive sanctions. pauladams, bbc news, kyiv. olga lautman is a senior fellow at the center for european policy analysis and co—host of the kremlin file podcast. thank you for coming on. it's hard to look into the future but what you think russia is

well, one frenchman has been testing that theory to its limit. tom brar—da has the story. here's something you definitely don't see every day. this is ouka the dog and his owner, shams. a video shams posted of the two of them paragliding among the peaks of the french alps has taken off on social media. the first video we did, it did maybe 150 million views. i think most of the people were... like, it's something completely amazing, and they never saw that before. what gave you the idea to take him paragliding? well, the first thing i noticed is ouka was not afraid of ice. for example, when we would go hiking, he was standing super on the edge of the cliff, and after that, i started to play with my own glider to teach him that it's ok, it's not scary and he was super fine with it. after that, we checked if he was ok to wear a special harness for flying.

so, i teach him to come between my legs on command, so i said "decollage" — it's "take off" in french. and then we ran together andjust run, run, run and we take off. can you describe for me what it was like when you first met each other, when you first got ouka? before i got ouka, i was not in my best period of life. like, i was not working so much because of the covid. i was having, like, some personal issues in my life. and, yeah, iwas, like, fighting a big, big depression, actually. courseouka was not very lucky or so in his life. he has been abandoned two times. the second owner of ouka, i think they were not taking him outside so much. when they gave him back, he was full of parasites, he was really in bad shape. i think i gave ouka the life he was needing to have. he pushes me, yeah, to wake up in the morning and to find

motivation to do stuff. so, yeah, ithink i need to tell him, like, a big thank you. their adventures perhaps prove that you can, in fact, teach an old dog new tricks. tom brada, bbc news. a winter heatwave is forecast to hit los angeles with unseasonably hot temperatures on super bowl sunday. according to forecasters, it could be the hottest kick—off in super bowl history — with temperatures close to 90 degrees. the los angeles rams take on the cincinnati bengals at the so—fi stadium. you can reach me on twitter — i'm @ sipusey.

hello. there is more wind and rain in the forecast, not only for the rest of the weekend, but indeed throughout the coming week. sunday looks like this. heavy rain affecting many parts of the uk, windy weather across the south, lighter winds further north. but on the satellite picture, you can see this shield of cloud racing in from the atlantic. this will bring wet weather to start sunday across western england, wales. the rain quickly getting into northern ireland, northern england and up into southern scotland as well. for east anglia and the south east, the day will start off on a dry note, but rain will arrive here through the afternoon. northern scotland likely to stay mostly dry with some spells of sunshine and just the odd shower, and slightly drier conditions could develop in northern ireland through the afternoon. the winds across northern areas are relatively light. southern areas, brisk winds. those are the average

wind speeds. the gusts could touch 50 mph for english channel coasts. but it will be relatively mild, 7—11 degrees. a very, very soggy sunday evening across east wales, central and eastern parts of england. that rain taking a long time to clear away. some drier conditions will develop out west, but with some showers. a fairly brisk northerly breeze, but i think given the strength of the breeze, it's not going to be a particularly cold night. but low pressure will still be close by into monday morning. showers circulating around that low, some brisk winds. just a little bump in the isobars, a ridge of high pressure just trying to drive things out as it topples in from the west. so, we will see some early rain across southern parts. that will clear to a mix of sunshine and showers. some of those showers wintry in scotland, especially over high ground, but potentially even to lower levels. feeling relatively chilly, i think, on monday given the strength of the breeze. top temperatures between 6—10 degrees. into tuesday, we see another band of rain pushing in from the west, some snow for a time across high ground in scotland and some wintry showers following on behind with some sunny spells in between. top temperatures on tuesday between 6—11 degrees. it is going to be another windy day, but those winds could well step up a gear as we move into wednesday thanks to this deepening area of low pressure.

lots and lots of white lines on the chart here, lots of isobars squeezing together. while the details of this forecast will change, it does look like we could see gales or severe gales in places on wednesday with some heavy bursts of rain. but it will be really mild for a time, turning chillier towards the end of the week.
