it's understood that a group of detainees armed themselves with weapons during a power cut. the home office says no one was injured during the incident at harmondsworth detention centre and the people involved have been returned to their rooms. our correspondent, emily unia, told us more. this happened last sunday at the border for centre this happened last sunday at the borderfor centre in kent. the man who carried out this attack was andrew leak, 66—year—old man from high wycombe. he is understood to have killed himself after throwing two or three crude incendiary devices. nobody was seriously injured in the attack, although so —— two people sustained minor injuries. they had to move 700 people to the manston processing centre for safety reasons and we have had a statement from county down —— counterterrorism police...

take us back to the incident at the harmondsworth detention centre. what do we know about that and what this group of detainees had armed themselves with, for example? it happened in the early hours of this morning. there was a power cut. we have limited information. the bbc understands detainees armed themselves and left the rooms and went into the courtyard of the centre and according to the home office, they caused a disturbance. specialist officers from the metropolitan police were called, along with prison service staff. we have no reports of any injuries or any detainees leaving the site. the last update was that they were all backin last update was that they were all back in their rooms. but i understand that the tiny that harmondsworth may be moved on to make space for people being processed at manston in kent.

passengers are being warned to expect "significant disruption" on the railways, despite strike action being called off late yesterday. tens of thousands of rail workers had been due to walk out in the long—running dispute over pay and working conditions. strikes planned for monday and wednesday have also been cancelled — as negotiations between the rmt union and train operators continue. our business correspondent, marc ashdown, reports. today's strike action may have been called off but widespread disruption will continue. network rail welcomed the decision but said that services which had been cancelled can't be reinstated at such late notice. a reduced strike timetable means just 20% of services will run across england, scotland and wales. those which do will start much later and finish by the early evening. thousands of members of the rmt union at 1a rail companies, and network rail, are involved in the long—running dispute about pay, jobs and terms and conditions. we are at a late venue tonight and then we are coming back tomorrow morning,

so it will affect us. we are at definitely affected by that, i am going to london now and i have to take taxi back which costs us £200. the problem i find is the information's not conveyed very well, so i know there's some trains running but i don't from what stations or what times, at the moment. the union said that previous strikes had made the rail companies see sense, and it looks forward to intensive negotiations to try and reach a settlement. the rail delivery group said it's glad the union stepped back from the brink, and it too is committed to negotiating, but it warned passengers will see disruption on monday as well, as it's too late to change strike rosters. the advice is to only travel if absolutely necessary. mark ashdown, bbc news. our correspondent, luxmy gopal, is at leeds station. let's catch up with the impact at leeds station. a train up the platform but how busy has it been, compared to a normal day? yes.

there are some services running but they are severely disrupted because they are severely disrupted because they are severely disrupted because they are being wound down earlier than they normally would be. the last trains to places such as sheffield, york, birmingham new street, will be by 6:30pm at the latest. some of the passengers i spoke to today had not been aware of it and some of them had turned up and were a bit confused by the fact that train services were not running but many of them were sympathetic to the cause of the strike action that had been planned, which as we know is the long—running dispute involving the rmt over pay and conditions. just to reiterate the advice that you heard from the report, network rail are saying that passengers should not travel today unless absolutely necessary and if you are planning to travel down the advice is to check before doing so. the disruption today will continue on monday as well because that was another date that the strike action

was to to take place. the third day was to to take place. the third day was going to be wednesday and network rail say they are working on trying to get a timetable up and running by then, to resume by then, but for today, the advice is don't travel unless you absolutely have to. ., ~' , ., , travel unless you absolutely have to. . ~ , ., , . thousands of people have been taking part in candlelit vigils in south korea, to remember the 156 people killed in a crush on halloween. the victims, mostly young people, were among around 100,000 people who had flocked to the popular itaewon nightlife district in the capital seoul. law—enforcement officials has conceded there was insufficient planning for an event that large. our correspondent, nick marsh, is there and sent this report. this vigil has been organised by one of the main civic action groups in south korea. they're anti—government

and are affiliated with the main opposition party. it is really more of a protest than a vigil. the people i have been speaking to here all afternoon and into the night want the resignation of south korean president yoon suk—yeol. they say that he and his government are responsible for the tragic loss of life on saturday night. clearly, we know that there have been police failings. not enough officers were deployed on saturday night, there was nowhere near enough planning, huge numbers and little to no thought being put into things like crowd control. whether the responsibility goes all the way up to government levels, and ultimately to the president, will be something that south koreans will have to decide. but one thing is sure — over the course of this week, the initial grief and the shock

felt by so many south koreans has turned into anger and has turned into a desire to get answers as to what went wrong. the us climate envoy, john kerry, is calling on richer countries to "step up" and provide money to help developing nations reduce their dependence on fossil fuels. speaking to the bbc on the eve of the cop27 climate conference in egypt, mr kerry praised the development of renewable sources of energy, but said the war in ukraine and the cost of living crisis had slowed progress. is there loss? is there damage in places in the world? yes, i mean, you'd be an idiot if you didn't acknowledge and obviously those countries with greater means across the board, and that includes some developing countries who have greater means, need to also step up and help in this transition.

but we don't view it, and we are not going to view it as compensation, we are going to view it as our efforts to try to help countries be able to adapt, be able to become more resilient, and obviously to address the challenges that they face as a result of some of the losses and damages. north korea fired four short—range ballistic missiles into the western sea on saturday morning, according to the south korean military. they say the missiles flew about 130 kilometres at an altitude of 20 kilometres. it's the latest in a series of launches this week, including a possible failed intercontinental ballistic missile. the russian private military company, the wagner group, has opened its first official headquarters in st petersburg. mercenaries employed by wagner have been accused of committing human rights abuses in ukraine and in west africa. tom brada reports. this may look like just another unremarkable office block. it is, in fact, the headquarters

of the wagner group, a russian militia unit notorious for brutality both on and off the battlefield. translation: the creation of such a centre was a long time coming. the only thing is that it appeared so late. it should've been opened before the special military operation. the wagner group has been active during conflicts across africa, in syria and, most recently, in ukraine. in september, reports emerged that the group was recruiting prisoners to fight in ukraine in exchange for their sentences being reduced. translation: the biggest sin is desertion! no—one backs down, no—one retreats, no—one surrenders! british military intelligence says there are 1000 wagner mercenaries deployed in ukraine and their involvement fits into a broader pattern of russian ruthlessness.

ukraine says it has identified tens of thousands of possible war crimes by russian forces — something which russia denies. and on friday, president putin changed russian law. the army can now call up serious criminals who've recently left prison, meaning convicted murderers and drug dealers could soon be on the front lines. imagine how desperate he is as he promised to take over ukraine, the whole biggest nation by size in europe, to take it over in days. and now, after almost eight months here, to scrap for even the criminals to replenish his forces. critics say mr putin's latest decision reflects how badly russian troops are faring on the battlefield. ukrainian troops are currently pushing hard to recapture the city of kherson in the south. the wagner group used to be an organisation which traded in secrecy and operated in the shadows. the establishment of an official

wagner head office suggests russia is willing to be upfront about more underhand tactics. tom brada, bbc news. twitter�*s new owner elon musk has defended his decision to sack about half the firm's workforce without warning. mr musk said the social media platform was losing large sums of money every day. he's insisted twitter�*s commitment to content moderation remains unchanged, despite the loss of key staff and anxiety among advertisers. in an interview, elon musk revealed that twitter was losing around $4 million a day, meaning costs had to be cut. he promised twitter wouldn't degenerate into what he called a "free—for—all hellscape' when content moderation is loosened. but advertisers including general motors have withdrawn their business, which is likely to lead to a drop in revenues. and now twitter faces lawsuits from the hundreds of employees over the way they were fired. i'm joined now by peter kafka,

host of the recode media podcast. he joins us from new york. good to have you with us today. some big advertisers feeling nervous about the new boss of twitter but can they be brought back? i about the new boss of twitter but can they be brought back?- can they be brought back? i think the could can they be brought back? i think they could certainly _ can they be brought back? i think they could certainly be _ can they be brought back? i think they could certainly be brought i they could certainly be brought back. elon musk, i think people forget now, is one of the more charismatic people we have seen in the tech business for a long time. i have seen people swoon in a room when he is there. he is doing his best to make himself less palatable to a lot of people right now and he is not used to having to woo people who spend advertising money and you can see that in the way that he is reacting to their spend, he is threatening to go thermonuclear on them, which is generally not how you persuade someone to go spend money on your platform. persuade someone to go spend money on your platform-— on your platform. already, you have not

he going to make — people on twitter right now. how is he going to make money, - people on twitter right now. how is he going to make money, beyond l he going to make money, beyond cutting costs, which he has tried to do with sacking about half the workforce? how is he going to make money out of this? he workforce? how is he going to make money out of this?— money out of this? he would like to have advertising. _ money out of this? he would like to have advertising. and _ money out of this? he would like to have advertising. and he _ money out of this? he would like to have advertising. and he is - money out of this? he would like to have advertising. and he is floating | have advertising. and he is floating all sorts of ideas to get other revenue and there. the first is this $8 and the subscription product that would allow people to verify themselves under the bonuses. supposedly. themselves under the bonuses. supposedly-— themselves under the bonuses. su--osedl . ~ . , ., supposedly. which there has been a lot of pushbaok _ supposedly. which there has been a lot of pushback on. _ supposedly. which there has been a lot of pushback on. a _ supposedly. which there has been a lot of pushback on. a lot _ supposedly. which there has been a lot of pushback on. a lot of - lot of pushback on. a lot of pushback- _ lot of pushback on. a lot of pushback. it _ lot of pushback on. a lot of pushback. it is _ lot of pushback on. a lot of pushback. it is supposed i lot of pushback on. a lot ofj pushback. it is supposed to lot of pushback on. a lot of. pushback. it is supposed to go lot of pushback on. a lot of - pushback. it is supposed to go live early next week. i imagine he is going to throw a lot of stuff against the war and see what sticks, which is something that people in silicon valley like to see generally. but that is usually for untested start—ups, not for established companies like this. fix, established companies like this. a period of experimentation no doubt ahead for twitter. let's go back to those advertisers. elon musk himself is blaming the fact that some

advertisers have press tours on their spending on activists, he says have persuaded these act —— advertisers to hold off on spending at the moment but is there enough self—awareness from elon musk himself about issues that the advertisers might have with him and the way he conducts his business customer it is an infantile response. customer it is an infantile resume-— customer it is an infantile response. customer it is an infantile resonse. ~ ., , , ., response. when he initially started complaining _ response. when he initially started complaining about _ response. when he initially started complaining about the _ response. when he initially started complaining about the advertiser i complaining about the advertiser just a, i was shocked to see, even from someone like him, i asked one of his advisers if he meant what he said or if he was screwing around, and they said no, he believes this. he does not have self—awareness about how this comes off or anyone in his circle pushing back, saying if you want people to spend money, a good way is to be solicitors of them, not aggressive. i think he has been surprised at the pushback. find been surprised at the pushback. and of course, been surprised at the pushback. and of course. he — been surprised at the pushback. and of course, he sacked the board. he can do what he wants, at the pace that he wants. do you think

ultimately that the people investing already on twitter will stay invested or will they be looking to another social media platform, maybe when we don't even know about yet, for their future social media needs? i think it is easy to say that this is a lot like american liberals who promised to move to canada if donald trump was elected but again, moving away from the country you live in is away from the country you live in is a big deal. just using a social media platform less, that isjust the way of the world. that happens organically and naturally. you don't really need an impetus to do it. and if you find these in you are using for free less fun, you willjust use it less, you don't have to go anywhere else. you canjust it less, you don't have to go anywhere else. you can just be less interested in it and that has always been twitter�*s problem. other social networks are inherently more interesting to many more people. good to speak to you. sport now and a full round up,

from the bbc sport centre. we start with the cricket and at the t20 world cup, england are into the semifinals, but they made hard work of it in theirfinal group semifinals, but they made hard work of it in their final group match. england had to win to progress. they restricted sri lanka to 141. england looked comfortable in their run chase. alex hales hitting eight boundaries but the wicket soon tumbled. and england scraped over the line. chris woakes with the winning runs with just two balls to spare. england's women have sealed their place in the rugby union world cup final this morning but it was not the most comfortable victories that many expected. they will need to up their game if they are to beat the hosts new zealand saturday.

excited and expectant. england supporters turning out in auckland hoping for a straight forward route to the final with an amateur canada side in their way and confidence was high. england are the number one side in the world and have not last a match now in over three years. victory is something their fans have now in over three years. victory is something theirfans have become accustomed to. something all of their opponents have become accustomed to is the line—out and driving maul and once again, it proved unstoppable. after england scored again, canada could have been forgiven for letting their heads drop but instead, they showed their grit and pace. canada's confidence grow. they pulled themselves right back into the game before the break. the favourites were rattled. but after the restart, a moment of magic. from behind their own try line, mcdonald made a break and from there, it was

pure box office. the winger turning on the afterburners to power away. canada dotted down once more but the game belong to england. the relief evident and a place in the world cup final concern. i evident and a place in the world cup final concern.— final concern. i was aware of them closin: final concern. i was aware of them closing in. — final concern. i was aware of them closing in. i— final concern. i was aware of them closing in, i remember— final concern. i was aware of them closing in, i remember her- final concern. i was aware of them i closing in, i remember her shouting at me, i know you arejogging that i am really sprinting right now! as a winger, you just need to run as fast as you can and click and luckily we did. ., ., , , , did. england will need to step up their performance _ did. england will need to step up their performance if— did. england will need to step up their performance if they - did. england will need to step up their performance if they are - did. england will need to step up their performance if they are to i their performance if they are to lift the cup next weekend, taking on new zealand in their back yard. they came through a real battle in their semifinal against france, eventually winning by a single point.

at the rugby league world cup, england's men face their most physical test so far this afternoon. it is part of a double—header in wigan. the women are already under way in their group stage match against canada. england scored the opening try inside the first minute. england's impressive defence meant a lot of the first period was spent in the canadian half and they crossed the canadian half and they crossed the line a further five times. and this is how it is going at the moment. around 20 minutes to go. they are pretty much home and dry, you could say. you can catch the action on bbc two, on the iplayer and the sport website. another blow for gareth southgate.

ben chilwell has been ruled out of the world cup. he limped out of the champions league win for chelsea in the week and scans have revealed he suffered a significant hamstring injury. england start their campaign on november the 21st. some managerial news and wolves have appointed a new manager. the spanish coach will take charge later this month as the premier league causes for the world cup. he was the first choice to take over. we will be back with more throughout the afternoon. sinn fein's vice—president, michelle o'neill, has been addressing her party's conference in dublin. sinn fein became the largest party in the stormont assembly at the last election, but michelle o'neill has not been able to take up the role of northern ireland's first minister, while the dup refuses to go back into an executive.

our correspondent, emma vardy, is live in dublin for us this morning. she has delivered that speech, the first since that historic vote for sinn fein in may in the northern ireland elections was what has been saying? ireland elections was what has been sa in: ? ,, ., ., ireland elections was what has been sa inc? ,, ., ., , ., ., saying? she got a big round of applause _ saying? she got a big round of applause her— saying? she got a big round of applause. her messages - saying? she got a big round of applause. her messages went | saying? she got a big round of- applause. her messages went down pretty well. as you might expect. her message was this, think back to those elections in may, an historic moment when sinn fein became the largest party in the northern ireland assembly at stormont because it was the first time a nationalist party had held that position. michelle o'neill of sinn fein would have been entitled to the northern ireland first minister role but she did not get to take office because the dup have been blocking power—sharing since then in a protest over the brexit arrangements. michelle o'neill are saying today that the dup are punishing ordinary voters, leaving

them without a government at a time of cost of living crisis. what she said is that she does not believe it is the dup�*s opposition to brexit keeping them out, she said the deal decently don't want to sit in government with a nationalist first minister. that was her message. that is how she says she is reading it. there has been a pretty strong response from the dup about this. they say they have repeatedly said they will go back into government and are prepared to do that but they are not prepared to do it while at the moment there is this irish sea border, causing problems getting from —— good is getting from great britain to northern ireland. they say that is why —— why they are saying out of government. very strong words from sinn fein today about the stormont crisis. but you have to remember of course if you think back a few more years, northern ireland of course, this is not the first time it has been left without a government. in 2017, the government collapsed and that time

it was sinn fein walking out. you need to take a wider look at history when you hear things like this at party conferences. but sinn fein are in a confident mood today because of their success at the last elections and they hope that eventually when power—sharing does return, that one day michelle o'neill will be taking up day michelle o'neill will be taking up that first minister role. it is historic, not only because it is the first on the nationalist had been in the majority in —— the largest party in northern ireland, but because of the story of this party, once upon a time sinn fein was the political voice of the ira, now at the top of government, what a journey they have been on. they are celebrating their recent success in the polls today. thank you very much. now it's time for a look at the weather. thank you very much. good afternoon. we have low pressure firmly in

charge of the weather this weekend. it looks like it is going to bring rain through today, that'll two showers as we move through tonight and into tomorrow and it will be windy at times. here is the pressure chart, area of low pressure throwing its first weather front out towards us today on the showers follow on tomorrow. you can see the extent of the rainfall on rainfall radar. northern ireland is now clear and those brighter skies pushing into scotland and then into fringes of the north—west of england, and wales. it further east, staying cloudy and damp throughout the afternoon. spells of rain or drizzle. quite busy on the coast —— quite breezy. tonight, damp and cloudy in the south—east. clear elsewhere but through the night, we started see blustery showers pushing into northern and western areas and the rain any south—east could be heavy with rumbles of thunder in places. a mild night in the south.

cooler in the north. temperatures rising as we head into tomorrow. extreme right—wing terrorist ideology was behind the firebombing of a migrant processing centre in dover last sunday, say the police. a �*disturbance' at a london immigration removalfacility during a power outage — with reports suggesting it was caused by the detainees
