hello and welcome to world news today. pope francis has concluded a landmark summit in the vatican by promising to take concrete steps to tackle sexual abuse within the catholic church. in his closing remarks he referred to priests found guilty of abuse as "tools of satan". the pope said the abuse reminded him of the ancient pagan religious practice of child sacrifice. bishops have been told to put in place new measures to prevent abuse and punish perpetrators. but victims‘ groups say it's still not clear what those new measures will be, and have expressed disappointment at the lack of immediate action. our religion editor martin bashir filed this report from vatican city. me culpa. words of repentance by bishops on the last morning of this four—day summit. they've heard presentations on responsibility, accountability and transparency, and there is no doubting the challenge. a mission demanding notjust words, but real, concrete action. this morning's preacher, the archbishop of brisbane, says every church is now on notice. i think we just have to accept that our moral authority, and our credibility in more general terms, has been massively damaged. it's shot to pieces, isn't it? i accept that our credibility is shot to pieces. how will it be restored? over a very long period of time and with great tenacity. no amount of spin in all the world is going to do the trick. as the pope gave his traditional sunday address, the vatican announced that he will soon issue a proclamation with new church laws to protect children. they're drafting a handbook for bishops, and a task force will be established to help churches struggling with safeguarding. but peter saunders, who was abused by a priest, says these measures are simply not enough. it had a great opportunity this weekend to make real change, and it has failed to do so. somehow, i think we're going to be leaving disappointed, but also encouraged that the eyes of the world have been on this event. pope francis closed the summit by adopting the language of warfare, calling for an all out battle in the fight against sexual abuse. faithful catholics have demanded action. what they have received today are another set of promises that they must wait to see fulfilled. martin bashir, bbc news, at the vatican. the colombian authorities say more than 100 venezuelan soldiers have now deserted and crossed over into their country. they said most of the soldiers were answering calls by the venezuelan opposition leader, juan guaido, to abandon president nicolas maduro. the united states, colombia and brazil say they will step up the pressure for political change in venezuela, after mr maduro's government blocked an attempt to deliver humanitarian aid. a meeting is being held in the colombian capital bogota on monday to discuss the crisis. the us secretary of state mike pompeo says the president's days are numbered. there have been hundreds killed from starvation over the past weeks and months, millions of people having to flee their homes, 10% of the venezuelan population. the days and weeks and months ahead, the madeira regime will understand that it's days are numbered. let's speak to the bbc‘s chris buckler, who's in washington. this idea that concrete action has to happen. any ideas what that will be? i think it is going to be yet more sanctions, yet more diplomatic pressure. if you take a look at who vice president mike pence is meeting in bogota, he is meeting countries who are part of what is known as the lima group, a series of countries across the americas trying to find a peaceful solution to the problem that have been plaguing venezuela for so long. certainly there is going to be more pressure put on nicolas maduro to try to force him from the presidency are possible, but we are not talking about military action this weekend. nonetheless, if you listen tojuan guaido over this weekend, he is saying that all options have to remain on the table, and certainly the white house is continuing to dangle the prospect of military action further down the line, but i think it is not now. but you get the sense here in washington that they are watching things in venezuela very closely, and certainly we have seen the likes of the national security adviser here, john bolton, not to go to hanoi, delayed his trip to vietnam for that summit between kim jong—un to vietnam for that summit between kimjong—un and to vietnam for that summit between kim jong—un and donald trump specifically to watch developments in venezuela closely. and what about this aid? it is sitting on the board are not getting in. any plans how to get it into the people who needed?” think there is undoubtedly an increasing pressure on all of the countries to address that issue. as much as we talk about sanctions and diplomatic pressure, there is a feeling amongst all of these countries that there is an increasing pressure to get aid in there, that this food, these medical supplies, a badly needed. at the same time, i suspect some in washington and other countries are watching this very closely, and thinking of the pictures of aid being blocked going to venezuela, some even being set on fire, may not play well inside venezuela, and that could be important in terms of their ultimate aim of trying to remove nicolas maduro. chris buckler, thank you very much for bringing us up to speed. next, as the first ever summit between european and arab countries got under way in in egypt, theresa may was on the sidelines trying to secure a breakthrough on her brexit deal. with just 33 days until the uk is set to leave the eu, the british prime minister announced another delay for a parliamentary vote on the deal, which she's still trying to make changes to. 0ur political editor laura kuenssberg sent this report from sharm el—sheikh. she might fly around the world to do the deal but how much further can theresa may really get? massed ranks at home rejected her compromise and now they won't get their safer another two weeks. we will not bring the meaningful vote back this week but it will happen by 12th march and we still have it within our grasp to leave the european union with a deal on 29th march and that is what i am going to be working at. when it seems everyone's pulling in different directions, the big problem is still the irish backstop, the guarantee in the brexit deal against there ever being a hard border. the uk wants an extra legal promise that it can't last forever but to the eu's frustration is obvious. this is a situation which uk has created for itself and we are just standing by our position which has been solid from day one. this is not a joyful process, and while the prime minister is here trying to push for a tweak to her deal, many at home are pushing her to delay the whole thing. she needs much more than small talk, some eu leaders are talking about delay, too. if there is also at the beginning of march no support for the deal we have, then i think it would be good to postpone the brexit, because a no deal scenario is bad for the european union but it will be extremely bad for the uk. that is not what the prime minister wants. and although there has been stubbornness on both sides perhaps, is there now a glimmer of a move? you need two to dance tango. and i know how to dance. right now, any movement from eu leaders in public is a scarce. tonight, the test for the prime minister is to see if any of her counterparts might join her on the floor. laura kuenssberg there in egypt. now it's lights, camera... and almost time for action. hollywood is getting ready for its biggest night of the year — but this year's academy awards will be a show with a few differences. barbara plett usher is on the red carpet in hollywood. they have just moved to the media off the red carpet to make way for the stars who are expected to arrive in the next hour or two, and later today when the oscars are handed out, millions of people around the world a re out, millions of people around the world are going to be watching. but there has been significant controversy leading up to this, because the organisers trying to make changes that some said were too commercial. will gompertz, our art editor, has been looking into this story. here is his report. the winner is cecil b demille... it's 1953 and the first televised 0scars ceremony, the annual awards presented by the academy of motion picture arts and sciences — which won't be winning any prizes for the way it has handled this year's tv show. i thank you. what with host kevin hart quitting after past homophobic tweets came to light. and then there was a botched attempt to create a best popular film category, followed by an ill—fated plan to bury the cinematography award in a tv adbreak. added to which, viewers are switching off in their millions. i think that the academy took some ill—considered decisions this year and i think that there will be a price to pay. and when the academy steps in it as badly as it did this year, and when it embarrasses itself so publicly, there are consequences, and i think you're going to see those consequences. what's the worst—case scenario? well, i think the worst case for the oscars would just be being irrelevant. this is it! the 0scars are unlikely to sink without trace, but they could do with another titanic, a blockbuster movie and best film winner with an a—list cast, delivering a record—breaking tv audience that keeps advertisers happy, which is very important to the academy. the film academy gets more than 85% of their income from this one night, the telecast of the oscars. but the television ratings have been going down quite dramatically, last year was like a ali—year low. an arthouse film like roma, a frontrunner for best picture this year, is not the sort of mainstream commercial movie likely to be a ratings winner for the oscars tv show. hence the attempts to make it more audience friendly, such as not showing the cinematography winner live on air, an idea that didn't go down well with academy members old or new. ijust think you have to make the people at home suffer through watching best cinematography. i think it's the price to pay, i think you have to compromise between the show and the principles of the academy. which one is more important? er...| guess both! the principle! and therein lies the nub of the oscars problem, artistic principles or commercial imperative, art or money? that's show business. will gompertz, bbc news, hollywood. there is lots of curiosity as to what they will come up with, and a lot of old—fashioned suspense, especially in the best film category, because although there are frontrunners, it is still a pretty diverse field, so lots to look forward to. baba, thank you very much. do stay with us here on bbc world news today. still to come: we will be returning to the oscars, speaking to journalist ben zauzmer about why he thinks the academy awards are more political than ever prince charles has chosen his bride. he proposed to lady diana spencer a few weeks ago. as revelations go, this had its fair share of bullets. the world's first clone has been produced of an adult mammal. scientists in scotland have produced a sheep called dolly using a cell from another sheep. citizens are trying to come to grips with their new freedom. although there is joy and relief today, the scars are everywhere. not for 20 years have locust been seenin not for 20 years have locust been seen in such numbers in this part of africa. some of the swarms have been ten miles long. this is the last time the public will see this pope. very soon for the sake of the credibility and authority of the next pope, benedict xvi will in his own words be hidden from the world for the rest of his life. this is bbc world news today. the latest headlines. pope francis has promised concrete action to tackle child sex abuse at the end of a roman catholic church summit on paedophilia. abuse victims have described the colombian authorities say more than 100 venezuelan soldiers have now deserted and crossed over into their country. they said most of the soldiers were answering calls by the venezuelan opposition leader, juan guaido. let's return now to our top story, the conclusion of the catholic church's landmark summit on child sexual abuse. i'm joined byjack valero from the organisation catholic voices. we heard early on that the church's credibility has been shot to pieces, and that's right, isn't it? of course, and as a catholic, i want this to end. i want there to be no more abuse, perpetrators to be punished and victims to be recompensed and helped in whatever way they need. but i do have hope from this meeting. ifound way they need. but i do have hope from this meeting. i found the organiser, a jesuit priest, from this meeting. i found the organiser, ajesuit priest, and he said that people felt different towards the end, that they felt transformed. many had been asked to listen to victims before the meeting, and they did, and during the meeting they listen to victims, and now people notjust from europe but from africa and asia are saying that this is a battle we must fight, we must fight it together. and don't forget this is the first institution to call its worldwide leadership together to fight this evil of sexual abuse, both in the church and outside. but victims have said, today we have heard from them saying they have been frustrated by the lack of concrete details to come out of this. i think concrete detail is coming out now. the pope is going to write a document within days. within two weeks there will be a set of guidelines for bishops to follow, and a task force for any bishop who doesn't have the people to implement it, they will be helped from rome to do so. and as catholics, we expect detailed things to happen, otherwise this has been a waste of time. but i'm hopeful because all of the things that are coming out are saying we are going to do this. tomorrow morning they are organising a meeting with all the heads of the departments of the vatican as to what they are going to do, and the pope is working on these points. he himself released a list of 21 points at the beginning. he wanted them discussed, and now he is going to ta ke discussed, and now he is going to take whatever people said and make that into rules for people to follow. so i think real action is going to happen. jack valero, thank you very much for your input. hugh woozencroft has all the sport. hello. manchester city have retained the league cup beating chelsea on penalties, after extra—time. it's the first time city have retained a major trophy in their history, but the end of the game was marked by chelsea's kepa arrizabalaga refusing to be substituted in the closing moments. david 0rnstein watched the game at wembley. it was two weeks ago to the very day that manchester city thrashed chelsea 6—0 in the league, and they came into this match as firm favourites. manchester city have been beating all comers, while chelsea are having a troubled campaign on and off the pitch. the main bulk of the match wasn't much to write home about, a couple of chances for both sides. it was a fairly even contest that manchester city marginally had the better of. but it came to life in extra time because of an extraordinary incident between the chelsea coach, merritt c0 salary, and his goalkeeper, sarri wa nted c0 salary, and his goalkeeper, sarri wanted to substitute kepa and bring on willy caballero. but kepa refused to go off, sarri reacted furiously, storming off down the tunnel before coming back at full time. the pair had to be separated, they wouldn't speak to each other. penalties ensued, and in fact kepa wasn't a key protagonist. he didn't even save a penalty, but misses from giorgio and david luiz proved key, and manchester city have retained the trophy for the first time in their history, and one that wrote the first of what could be an unprecedented four trophies this season. city's rivals manchester united did them a favour by holding liverpool to a goalless draw at old trafford in the premier league title race. city and liverpool were level before this game, but liverpool — who haven't won the league title in 29 years — now lead by a point. jurgen kloop may see it as a missed opportunity, as they continue a patchy run of four draws in their last five matches. we didn't create enough, that is the truth. it is clear to us that if united plays with the team of the last couple of weeks, they try everything and can win the ball, we headed it all the time, and we didn't do well with that, to be honest. that was the thing, but we ta ke honest. that was the thing, but we take that, that is how it is, so it isa take that, that is how it is, so it is a point because we have won more than before, and it doesn't feel 100% like that. that result sees manchester united slip out of the top four as arsenal won 2—0 at home to southampton. alexandre lacazette and henrikh mkhitaryan got the goals, as they go a point above united. leicester city has sacked manager claude puel afterjust 16 months in charge. it follows yesterday's 4—1 defeat at home to crystal palace which means they're with a win in the premier league since new year's day. they were also knocked out of the fa cup by league two side newport county last month. the holders ireland secured a bonus point victory over italy in rugby union's six nations championship, the result the holders will have wanted but probably not the perfomrance. which was laboured at times — the home side were leading at half time before ireland scored two tries to win 26—16. italy will feel frutrated having come close to securing a losing bonus point — it's now their 20th consecutive defeat in the tournament. there is a bit of frustration in our group, but nobody has got a margin on italy. they have had ten point losses for the first three games of the championship, probably reflective of a competitive unit they have got. and wales stay top of that six nations, good news for theirfans. thank you. let's return to the academy awards, in a few hours' time, hollywood a—listers will be walking down the red carpet in what has been called the most political 0scars yet. joining me now is ben zauzmer. he's a reporter and 0scars analyst. analyst is the word. you have managed to prove that this is the most political 0scars yet. how have you done that? i did my best. i went through all 550 for best picture nominees in history, including the eight this year, and each one is political or not political. i have seen a good 300 plus, and the others i researched to determine if there either dealt with the political issue or if they clearly portrayed politics on screen. it turns out that on average, 38% of nominees are political, but this year it is 75%. so why, then? does your research extend that far? why do you think that this year particularly we have such a high number of political films up for awards? i think it is a films up for awards? i think it is a film by film case, but a good part of it is the current political climate here in the united states. some of the directly talked about the current political situation, whether it was vice talking about the rise of modern republican politics throughout the previous decades, or blachklansman, which ended going straight to donald trump himself, giving his speech after the cha rlottesville himself, giving his speech after the charlottesville attack. 0r himself, giving his speech after the cha rlottesville attack. or even roma, while it wasn't set in the present day, it was clearly making a message about the humanity of mexicans in a time in american politics where that has become a political issue. have there been any other times when politics have dominated? there have. this year was the most political year of the last 75, but if you go back 75 and 76, to 1942 and 1943, those years were tied at one ahead of this year. it is not surprising that era was political as well, because it was right at the height of world war ii. and given that we have this number of political films, does that give you an insight into which one will actually win? historically there has been a slight advantage for political films over not political films. 19% of political films have w011 films. 19% of political films have won the oscar, while only 15% of a political films have won the oscar. it is not a huge difference, not enough but to base predictions on, especially when six of the eight nominees are political in some way, it wouldn't help you too much, but my mathematical model does favour roma. i think we have set a record for the most times the word politics 01’ for the most times the word politics or political have been used in an article about the oscars. people go to the movies for escapism, to get away from all that. there are two camps on that question. a large number of people prefer films as escapism and want the oscars to be com pletely escapism and want the oscars to be completely free of politics. those people tend to be louder because the 0scars have been so political. i would bet if the oscars went on the other direction, you would have people complaining from the other side that these people have a big platform and they should be using that platform to talk politics. so i don't think you are going to please all of the viewers in either case. and lastly, just in a couple of seconds, who do you think is going to win? my model has roma to win best picture and best director, along with rami malek and glenn close for the top acting awards. thank you for sticking your neck out. we appreciated, and only a couple of hours now until we know for certain. thank you very much for being with us. you have been watching world news today. join me on twitter at any time. i am lewis vaughan jones, thank you on twitter at any time. i am lewis vaughanjones, thank you for your company. good evening. this time last year we were starting to feel the effects of the so—called beast from the east but not this year. there is still some cold air across siberia but we are not bringing it in our direction, instead we are importing air from the south west, very mild and even warm source of air which pushed temperatures today up above 19 degrees. 19.1 in parts of wales, that is a new february record for wales. there is some more of that weather to come through the first part of the week ahead, more warm sunshine but with frosty nights and a foggy mornings, by the end of the week, things will start to turn more unsettled, but not from the east, from the west. as we go through tonight, those temperatures after such a warm day will dip away, particularly towards the south, getting all the way down to minus six degrees, not as cold further north and west partly because of this extra cloud and because of this rain, that will gradually slide away north. also starting tomorrow with fog across parts of yorkshire up into north east england, some of that could be dense and quite slow to clear, but for the majority, tomorrow is another blue sky day with lots of sunshine to be had and once again, it will feel warm, unseasonably warm, 15—18d, one or two places could get up to 19 degrees. nine would be more typical for this time of year. it's all because of high pressure, but because it remains in charge on monday night into tuesday, it will turn chilly and i don't think we will have much of a problem with fog at this stage. most places on tuesday will have more fine weather and sunshine, just a bit more cloud scraping across the far north—west and again those temperatures widely15—18d, a few spots warmer than that. fog looks likely to be a problem on wednesday morning, particularly in east anglia down towards the south and some of that could be slow to clear. lots more dry weather with some extra cloud, the odd spot of rain for northern ireland and the west of scotland, temperatures may be coming down a little bit, but not much. the bigger change comes through the second half of the week, first of all this area of low pressure on thursday. that could introduce showers just about anywhere in the uk and as we head towards the weekend, there is their increasing chance of some rain. it will turn a bit cooler.
