rob macaire says he was not taking part in anti—government demonstrations in the capital tehran when he was detained for three hours after attending a vigil for the 176 people who died when iran shot down a passenger plane last week. the uk has said the ambassador‘s arrest was a "flagrant violation of international law" and has warned iran that it risks becoming "an international pariah". earlier donald trump sent a tweet, warning the leaders of iran not to kill the protesters, and that the usa was watching. our world affairs correspondent caroline hawley reports. this morning in tehran the iranian authorities stepped up security. they're on extra guard after public gatherings to mourn the victims of the plane crash turned last night into protests. chanting. iranians voiced their fury at the regime, calling for accountability after the military finally admitted it wasn't responsible.

was responsible. they chanted, "death to the liars", and they demanded iran's supreme leader resign. britain's ambassador to iran was accused by iranian media of fomenting the protests, though he says he left the scene as soon as the people started chanting. the foreign secretary dominic raab called his arrest illegal, and warned iran against continuing what he called its march toward pariah status. this morning the ambassador tweeted. .. "can confirm i wasn't taking part in any demonstrations. "went to an event advertised as a vigilfor victims of ps—752 tragedy." completely unacceptable. a breach, you're right, certainly of the vienna convention, and a whole range of things. iran is at a crossroads and have a decision to make. and the point we are making, the foreign secretary has said just this morning, we want to see things de—escalate, we want to see iran come back into that international fold and play their part. but they are at a crossroads and they have to make that decision. it took three days for iran to admit they had made a horrific mistake

by shooting down the ukrainian airliner with 176 people on board. senior iranian officials have apologised and promised lessons will be learned, but iranians are still asking why iran didn't close its airspace when it was braced for an american military response to the missiles it fired at us bases in iraq in retaliation for the death of qasem soleimani, the country's second most powerful man. chanting. and the anger is not going away. this morning protests have erupted again. and they're taking on a sacred tenet of the islamic regime, chanting here that their enemy is not america, but their own leadership. caroline hawley, bbc news, beirut. caroline hawley is in beiruit and she explained the response from iran is surprising considering the circumstances. i would imagine that iran with so much pressure on it, both

domestically and internationally, would have wanted to draw a line under it, but the iranian media has accused him of fomenting, inciting protest. we have just had a statement on the foreign ministry website which says rob macaire has been summoned to the foreign ministry because of his unconventional or inappropriate behaviour by attending what they call an illegal rally. we haven't yet had official confirmation from the foreign office, but we wait to get a reader of how but we wait to get a read out of how the meeting went and see how iran and the uk will proceed from here. one of the background elements to this, and rob macaire referred to it in his explanation, was that the vigil turned into an anti—government protest and there have been a number of anti—government protests obviously over the shooting down and then the denial of shooting down the plane which included a lot

of iranians among the dead, but also in the build—up to that anti—government protests because of the state of the economy. we have just seen a tweet from donald trump in which he says, "to the leaders of iran, do not kill your protesters. thousands have already been killed or imprisoned in the world is watching. more importantly, the usa is watching. turn your internet back on and let reporters roam free. stop the killing of your great iranian people." the americans in a sense are on the front foot at the moment because of this admission by iran on friday. and the world certainly is watching and those demonstrations are continuing. huge anger at the iranian leadership and, as you have heard, calls for the supreme leader himself ayatollah khomeni to resign. you have had people saying that it is not america that is the enemy, it is the iranian leadership themselves.

we are also getting reports that hardline militia are staging a counterdemonstration outside the british embassy in tehran, calling for it to be closed and for the british ambassador to be expelled. at the moment people are on the streets voicing two very different opinions about the future of iran and about how they see the world. it is interesting because on the one hand we have the stand—off between the americans and the iranians, long—standing. iran has often described the uk as being in america's pocket, the little satan to the big satan in the united states, and yet it was borisjohnson who was able to bring up president rouhani and have this grown—up conversation during the course of the week. in a sense britain potentially could have been a source of communication and now these events at the weekends events at the weekend are potentially damaging. it could potentially have been some kind of bridge. of course britain is also saying it supports the nuclear deal that the americans pulled out of,

anyway triggering this catastrophic in a way triggering this catastrophic chain of events and raising tensions between the us and iran so high. but it is a very difficult relationship that britain has with iran and has had for a very long time. spare a thought for the british iranian mother nazanin zaghari—ratcliffe who remains injail and whose family feared that these latest tensions between the us and britain will not in any way help her. the queen has attended church at sandringham this morning ahead of talks there tomorrow with senior members of the royal family on the future role of prince harry. it's understood it will be be the first time that prince charles, prince william and prince harry will have met since he and his wife meghan announced they would be stepping back from their royal duties. 0ur correspondent jon donnison reports. the queen arriving at church at sandringham on sunday is very much routine. what lies ahead on monday

is very much not. the queen's estate in norfolk is the venue for what has been described as the sandringham summit. she will come face—to—face with prince harry for the first time since he and his wife announced they intend to step back in their role as senior royals. also there will be the prince of wales and prince william. and harry's wife meghan, the duchess of sussex, is expected to phone in, to join the discussion from canada. officials have worked hard in recent days to understand what the sussexes want. there will, we understand, be a "range of possibilities to review". it is hoped "next steps will be agreed at the meeting". however, officials are stressing that any decision about the sussexes' future status will take time to be implemented. the trickiest area could be money, as the couple seek financial independence. this morning, the shadow foreign secretary, emily thornberry, made her views clear

on the issue of security. the british taxpayer should pay for the security of harry and meghan and theirfamily, as they do with former ministers. and if they decide they want to go to canada, of course they must always be protected. and underpinning it all is the human side. family divisions and, poignantly, a rift between two brothers. in the sunday times, according to friends, william is quoted as saying, "i've put my arm around my brother all our lives. "i can't do it anymore." a bond which he feels is now being broken. 0ur correspondent leigh milner spent the morning in sandringham — and gave us this update.

she arrived just a few minutes before ”am local time. she was wearing a light brown jacket, with a matching hat, of course. and she came down here, she was driven through the driveway, through the gates, towards the mary magdalene church, where the service, as i say, began about roughly an hour ago exactly. and it has been quite a tough day for the queen herself. with all that has been going on throughout the past week or so, but she put on a brave face, she smiled, she waved at the well wishers and it almost seemed as if it was business as usual for the queen. remember, she is quite used to this as the head of the church. it is her role, her responsibility. last year, when prince philip was very poorly he spent three days in hospital, she still came to the carol service and she takes that responsibility very seriously. the irish prime minster, leo varadkar, says he's made a decision on the timing of a general election but won't announce a date until he's met his cabinet on tuesday. speculation has been growing that the country will go to the polls in february. for more details on why mr varadkar made the announcement now, i've been speaking to our correspondent richard morgan in belfast. ireland's government has been

a minority government since 2016. the taoiseach, leo varadkar, has relied on a confidence and supply agreement with the main opposition party fianna fail and on the votes of independent members of the irish parliament. we knew an election was coming, there had been plenty of speculation about an early election. we thought maybe in the summer, but we think that is now moving we think to early february. why now? the government has had lots going on externally, notjust in terms of domestic issues. first of all, we have brexit. ireland's deputy prime minister simon coveney has been at the forefront of those negotiates with the european union in a bid to protect ireland's place within europe and its interests in a post—brexit world. given this deal on the table has been passed through the uk's parliament, that has all but been moved to one side. the other issue ireland has been focusing on is stormont and getting the institutions in northern ireland

back up and running in northern ireland. ireland has an interest in that. it is obliged to oversee that power—sharing is back up and running. yesterday the assembly sat for the very first time in three years and ireland and the uk government had worked together to bring this deal to the parties in northern ireland in order to get them back around the table and back into government. now those external factors have been dealt with there might be a sense the government can go to the people, go to an election and try and resolve some of those domestic issues in ireland. the opposition leader you referred to, michael martin, people might remember he was a finance minister before, do you get a sense that it is the opposition pushing this? they have said we have given you the space to do these important things in ireland's interests, but we cannot put off an election any longer? do they sense that perhaps this government is vulnerable? that confidence and supply agreement

saw fianna fail agree with the current government on getting a number of budgets through and the confidence and supply agreement was extended late last year but given that the domestic issues in ireland have been piling up there may be a sense that this is the time to go to voters. what are the issues? the first is housing and homelessness. not a week goes by with homelessness not being on the front pages or in the headlines. at the last count there were 10,000 people who were considered to be homeless. especially in dublin there is a sense of a real housing crisis. the health system is also facing its own problems, people waiting on trolleys in hospitals, waiting for beds. there was a possible motion of no confidence in the health minister, simon harris, that was going to topple this government and it was unclear whether or not he would survive a confidence vote. some of the independent mps the government relies on had given an indication they would not be

getting behind him and they would be tabling that motion. the headlines on bbc news... iran summons the british ambassador following what they say was his attendance at an anti—government rally tehran. rob macaire says he left when a vigil turned into a protest. urgent talks between the queen and prince harry and meghan will be held tomorrow over the royal couple's future. 8,000 people are ordered from their homes and manila international airport puts all flights on hold after steam and ash erupt from a volcano in the philippines. sport and for a full round—up, from the bbc sport centre, here's holly hamilton. and some good news for one of the williams sisters. and some good news for one

of the williams sisters. good afternoon. we start in the premier league and watford have moved out of the relegation zone after beating struggling bournemouth 3—0. abdoulaye doucoure opened the scoring — capitalising on an error by the bournemouth keeper shortly before half—time. captain troy deeney then doubled their advantage midway through the second half with this powerful close—range effort and substitute roberto pereyra completed the win in stoppage time to move watford out of the drop zone for the first time this season. arsenal women have gone three points clear at top of the wsl after thrashing brighton 4—0. arsenal controlled the game from start to finish, beth mead's late goal completing the scoring. they stay clear of second—placed manchester city and four points in front of chelsea who beat bristol city 6—1. serena williams has won her first title for three years. she beat jessica pegula in straight sets in the final of the auckland international and will donate her winner's cheque

of around £33,000 to the australian bushfires relief fund. williams will have another shot at a record—equalling 24th grand slam title, when the australian open starts a week tomorrow. i have been in the zone a few times, played pretty well in new york, just not in the final. then again in wimbledon, just not in the final. so iam wimbledon, just not in the final. so i am getting there, it isjust putting it together for the whole tournament. i am feeling pretty good, iam tournament. i am feeling pretty good, i am feeling fit, i have got some good matches, long rallies, short rallies, power plays, so this is what i needed going into melbourne and it is good. is what i needed going into melbourne and it is good. novak djokovic has led serbia to victory in the first atp cup in sydney, helping to sink spain

in the final. djokovic was unbeaten in the nations tournament, saving one of his best displays for his singles rubber against world number one rafa nadal winning in 2 sets. he was then was part of the doubles team that won the deciding rubber. he described it as one of the nicest moments of his career. in pool a of rugby union's european champions cup, northampton improved their chances of making the quarterfinals with a bonus point win over bennetton. in a game where the lead changed hands several times, the french side led 8—5 at the break, tommaso benvenuti crossing the line. the saints battled back with four tries after the break, fraser dingwall‘s score confirming the bonus point as his side eventually won 33—20. northampton are second in pool a. runaway pool a leaders leinster who did northampton a favour by thumping their rivals lyon 42—14. leinster have already qualified. lyon are third and host northampton in the final pool game. the england cricket squad has been hit by illness yet again. this time it's captainjoe root

who had to miss training in port elizabeth this morning due to a stomach bug. with the test series against south africa level at 1—1, the 3rd test starts on thursday. england are already without rory burns and james anderson who were forced to return home through injury. and although anderson is a big loss for the team, wicketkeeperjos buttler says jofra archer and mark wood are ready to replace him. a huge blow. the best seam bowler we have ever had and he was bowling fa ntastically well have ever had and he was bowling fantastically well in that last game, so it is a big loss. but i would like to see those two guys on the sidelines come in and potentially they are barely fast and they are exciting guys and woody is chomping at the bit to get back on the field and he has been working ha rd to the field and he has been working hard to get to that place. we know whatjoffre has hard to get to that place. we know what joffre has been hard to get to that place. we know whatjoffre has been able to do in his short test career so far. two exciting guys to potentially have

two come back in. that's all the sport for now. ben croucher will have the latest for you in the next hour. there are less than 20 hours left for the six candidates in the labour leadership to gain the backing they need to get to the next stage of the contest. sir keir starmer, rebecca long bailey, jess phillips and lisa nandy have the required number of nominations — leaving emily thornberry and clive lewis lobbying to get the backing of at least 22 of their fellow labourmps and meps. registered supporters — who are not full party members — will have 48 hours from 14th to the 16th of january to secure a vote by paying £25. the ballot will be open from 21st february to the 2nd of april. with the results announced two days later on the 11th days later on the 11th april. earlier i spoke to our political correspondent nick eardley who gave a rundown of the six candidates who are looking

to replacejeremy corbyn as labour leader. just to take you through how they are all doing. clive lewis has got four. he is not smiling like he is in that picture. keir starmer at the moment is the man to beat. he is far out in the lead on 68 and the opinion poll we have seen suggests he is doing well with the labour membership as well. but do not count on anything being guaranteed because on anything being guaranteed because on the far side we also have rebecca long—bailey. 26 nominations at the moment, but she is the preferred candidate for many on the left of the party and we suspect that once this campaign gets going proper we will see a lot of work from the last of the party, remember the membership is more left—wing than it was in the past, and a lot of them

will get behind rebecca long—bailey. clive lewis will struggle because he is one with the lowest profile, with perhaps the exception i lisa nandy
