it was not, no. i was not aware that this was happening to the extent it was. i really don't think anyone around me in the vicinity knew what was happening because timeframes that we know now, with this was happening, people were singing along, dancing, taking videos with the phone. there had been smaller indications right before that that there was something happening but because it's a festival, you kind of expect to see some of things that we saw before this really kind of took off. talk through what happened in the appointment was clear that this was quite a serious incident. right, i think more people that were very near the front, where this was happening, it was very clear that there was a lot of friction, a lot of moving back and forth. i think anybody who's been to a concert where it's standing room, and you get anywhere near the front or the middle, when one row or one group of people moves, i mean, the whole thing kind of moves. you kind of have to move with the crowd. and if one person stumbles in the midst of that, that can create some sort of domino effect and in our reporting, one of the concertgoers described it as a tower ofjenga blocks falling which gives you an image of what this was. i think if you were further back, police or emergency vehicles cutting through the crowd, they had sirens and alarms on but again, if you go to a festival, people are taken out throughout the day because of dehydration and exhaustion so i think for the people who weren't right in the mix of that, this just seemed like a festival setting where some of these things unfortunately do happen, but i think once people started filing out, when he finished, and people of course take to social media immediately after a show, that's when a lot of this really became clear, that this was much bigger i think than anybody knew. the music had been stopped a couple of times previously to allow people the chance to cool down and calm down. should someone have intervened earlier and put the brakes on and allowed things to properly stop and settle down? i think that'sjust a really tough question because, you're right, he did stop the concert multiple times. travis himself pointed out people who were distressed or needed help, waiting for security to come and get that person and take them to safety. but again, in previous events, i've been to every one, the same thing has happened, and in his normal concerts. people get amped up and energetic, there is a unique culture between fans and this kind of thing for better or worse does happen a lot during his concerts but he is always as vigilant as he can be in terms of people's safety. let's get some of the day's other news. security officials in iraq say the prime minister has survived an assassination attempt. rockets from a drone hit his home in the high security green zone of baghdad early on sunday. it comes a day after violent clashes between security forces and supporters of pro—iranian political groups in the capital. police in southern germany say three people have been seriously wounded in a knife attack on a high speed train. a man has been detained, and police believe there's no further danger to the public. the train was travelling between the bavarian cities of regensburg and nuremberg. russia has registered its worst daily figure for coronavirus infections — surpassing 41,000 for the first time. moscow remains the epicentre of the pandemic in the country and most public places are now disinfected every day. the rise in cases comes at the end of an eight—day nationwide paid holiday, introduced to curb the spread of infections. the polish government has denied that the country's strict abortion laws are responsible for the recent death of a 30—year—old woman who had complications with her pregnancy but wasn't able to get a termination. huge protests have been held in warsaw, and other polish cities, calling for the near total ban on abortion to be scrapped. poland is one of the most devoutly catholic countries in europe. courtney bembridge has this report. crowd chanting. chanting, "not one more". tens of thousands of protesters marched to the health ministry in warsaw, after the death of a pregnant woman reignited the debate over the country's strict abortion laws. it's been a year since poland's constitutional court ruled in favour of a near—total ban on abortion. protesters are highlighting the recent case of a 30—year—old woman who died halfway through her pregnancy. her family says doctors had been aware of severe foetal defects but refused to perform an abortion while the foetus still had a heartbeat, fearing repercussions. this is what we call the �*frozen effect'. that the doctors will be afraid to perform abortions so in theory, abortion is legal in poland now, under the parameters that a woman's life and health is in danger, but in theory we see many cases when the doctors wait until the last moment and they are afraid because they know they will be facing legal charges. translation: iza said to a woman _ in the hospital room, "i want to live, "i have someone to live for. "i don't want to die." iza did not receive help because she was pregnant, because the heart of the foetus was still beating. the polish government denies the law is to blame and says an investigation is under way into the two doctors involved but these protesters claim there are similar cases happening right across the country and they say there will be many more unless the ban is scrapped. courtney bembridge, bbc news. marches have been taking place in more than 200 cities around the world as part of what's been described as the global day of action for climate justice. tens of thousands of people took to the streets of glasgow where the un's cop26 climate talks are taking place. lorna gordon has this report from glasgow. even the driving rain couldn't keep them away. this, the biggest protest march through glasgow during cop. some had travelled just a short distance to get here, others were from the sharp end of the changing climate. i come from the philippines, and i am an indigenous person from the mountains. this is personally important to me because climate change is killing my people. if the climate summit has so far focused on the decisions made by world leaders and their teams gathered here in glasgow, today is about the people, the thousands gathered, calling for change. discussions inside cop today focusing on nature. tough topics loom large for the days ahead. i don't have many expectations for the official cop conference but hopefully all this, people getting together, will put some pressure on the decision—makers. whatever we can do, we want to contribute. i want to be on the right sidel of history and i think that one day we will look back at this and hopefully feel proud - of ourselves that we are here. i don't know where we will be in ten years, in 20 years, so i'm out here, so is my mum, my gran, my grandad, everybody�*s out here. i don't believe it until i see any results. there is no law binding commitments so we willjust have to see it. the afternoon was mostly peaceful, but there were a small number of arrests, including this group of scientists blocking a bridge. 0rganisers of today's events say there were over 300 climate demonstrations worldwide, from the streets of london... ..to here in amsterdam... ..to sydney in australia. we just want to ask you, from our heart, for your support. and people from around the world calling for action from those in charge... i know it's a big deal, to get together the 196 countries, to say, yes, that is what we are going to do. i wish that we can do that, that it happens here. those marching here today will be hoping for positive news during the final week of talks, that it's not too late to deliver the substantial change they want. lorna gordon, bbc news, glasgow. this is bbc news, a reminder of our headlines. hospitals overwhelmed after 100 people are killed in a fuel tanker explosion in sierra leone — many more are injured. an investigation is underway into reports that someone at a houston music festival in the us was injecting people with drugs before the crowd stampeded. president biden�*s efforts to introduce mandatory vaccines for businesses in the united states have been blocked for the time being. an appeal court raised constitutional issues over a new law requiring employees of large private companies to be vaccinated against covid—19 or tested weekly. many republican states have filed legal challenges, accusing the president of overstepping his authority. mr biden says it is about setting a national standard of safety at work. i've been speaking to sonia gipson rankin, a law professor at the university of new mexico. i asked her about the legal issues at the heart of the matter. we are at a pretty unique moment. as of friday, the united states department of labour occupational safety and health administration released their official regulations called emergency temporary standards, and what they said was, as you just mentioned, everyone must be vaccinated or agree to weekly testing, if you're not vaccinated, weekly testing and wearing a mask. the response that is coming from the petitioners, this is a group of states, private organisations, religious organisations, have argued that 0sha is exceeding their federal limits, they are impeding on interstate commerce and they are really stepping into things that belong to the states to decide and that this is outside the boundaries of work—based safety. 0sha you mentioned there, the occupational safety and health administration. so what is the test that the court needs to determine where federal authority begins and ends? well, we're going to be at a place, this is little bit tricky because this is happening in the fifth circuit in the united states, the fifth circuit court of appeals, but there are other cases around the nation. what happens next is the test to ask is this in the purview of 0sha, is this something that addresses workplace safety? in the united states at this time over 745,000 people have died, 1,100 people are dying related every day to covid—19 infections and so does this in some way, as it will impact 81 million employees, 32 million that are not vaccinated, does this fall into the purview of something that 0sha should be looking it? both sides have filed paperwork. what happens next, what kind of timescale are we looking it? what happens next, what kind of timescale are we looking at? we are in a little bit of a tricky space once again because this isjust the regulations that have come out. nothing is supposed to take effect untiljanuary of 2022 so what we're looking at is, as you said, both sides have filed and the litigation will attempt to go to the supreme court but we will see what happens over the next few weeks because the united states supreme court has denied hearing petitions over vaccination mandates. this will be a bit different as the defendant here is the united states. archaeologists excavating the roman site of pompeii in italy say they've discovered a room used by slaves, which they say gives an extraordinary insight into their daily lives. nina nanji reports a window into how slaves lived in ancient pompeii. it is a cramped space with three wooden beds. 0ne smaller bed is possibly a child's, indicating that the room could have housed a family. the room was found during an excavation of a large villa on the outskirts of pompeii. the city was engulfed in a volcanic eruption nearly 2000 years ago, burying it and its residents in ash. translation: it is an i exceptional cross-section of the life and daily work of a part of the ancient population that is little known through official sources, always seen from the point of view of the elites and here instead, we see the lives of slaves, servants, people of a very low social status. the room is exceptionally well preserved. there are earthen red jars, ceramicjugs and a wooden chest containing metal and fabric objects thought to be part of a horse's harness. casts were created of the perishable items using impressions they had left in the hardened ash. the ruins of pompeii remain a rich source for archaeologists. it is a city frozen in time and one of italy's most visited tourist attractions. nina nanji, bbc news. now for all the days headlines from the bbc sport centre. let's start with football and norwich city have sacked manager daniel farke despite victory today for the first time in this season's english premier league. norwich beat brentford 2—1. they scored twice in the opening half an hour, with goals from mathias normann and a penalty from teemu pukki. rico henry pulled one back for brentford. but daniel farke�*s side held on. they are still bottom of the table though and farke was dismissed less than two hours after the final whistle. another manager under pressure is manchester united's 0le gunnar solskjaer after manchester city had a comfortable victory in the derby at old trafford. the win may not have been as emphatic as liverpool's 5—0 victory in united's last home league game but this will do solskjaer no favours. united got off to the worst possible start when eric bailly turned joao cancelo's cross into his own net after seven minutes and after david de gea had produced a string of brilliant saves, bernardo silva got city's second just before the break. we second just before the break. have had a couple of difficult we have had a couple of difficult weeks. we had a couple of good results last week but today it is a couple of steps back again after a few steps forward last week but we need to have everyone back, fresh in their minds, ready to go and we need to look more like we started to look like before the liverpool game. towards the end of last season, start of the season, we looked a little bit more like what we wanted to. premier league leaders chelsea were made to rue their missed chances after a 1—1 draw with burnley. kai havertz opened the scoring for chelsea, only his second league goal this season. but burnley levelled through matej vydra who rescued a point for his side. chelsea are three points clear of manchester city at the top of the table. now to some big news from barcelona — former player xavi hernandez is returning to the club as their new manager, replacing ronald koeman who was sacked last month. xavi, had been manager at the qatari club, al sadd, since 2019, but they agreed on friday to let him join barca after his release clause was met and xavi signed a contract until 202a. he arrived back in spain on saturday and will be officially introduced to the media on monday at the nou camp. xavi got a glimpse of the job he has at barcelona as the catalan giants surrendered a three—goal first half lead to draw at celta vigo. the equalising goal came in the sixth minute of injury time and the result leaves barcelona down in ninth. meanwhile real madrid are leading at home to high—flying rayo vallecano. england and australia are through to the semi finals of cricket's men's t20 world cup. australia beat west indies, while england have qualified despite defeat to south africa. there was a blow for england though with an injury to opening batsmanjason roy. captain eoin morgan says he'll be a big miss if he's ruled out for the rest of the tournament. he is unbelievably important. he is unbelievably important. he is unbelievably important. he is a guy that epitomises everything that we are about end the changing room and the way we play. you see how commanding he is at the top of the audit not only in t20 but also 50 over cricket. two different partners in the two formats obviously but, yes, he is as close as we get to surmising how the changing room should play. that's all the sport for now. you can also go to the website for the latest in the paris masters. mother djokovic is now the number 1a a record seventh year, beating his childhood hero's record, pete sampras. for weeks now we've been telling you about the ongoing situation in la palma, as a volcano on the island continues to spew out smoke and lava. it's caused massive disruption and destroyed more than 2000 properties. but it hasn't deterred one plucky band of tourists as the bbc�*s tim allman explains. come to la palma and see the sights — well, one rather big sight in particular. now, if you wanted to take part in a classic car rally, an island in the midst of a volcanic eruption may not seem like the ideal venue, but do not underestimate the members of the canaries grand tour. money. volcano. sex. it is truly amazing. i mean, as long as it is going off and nobody is being hurt too much, then it is fantastic, the power of nature. it truly is. this is part of a 19—day adventure that covers all of the canary islands but clearly la palma was going to be a bit different. some bringing newer, less valuable cars just to be on the safe side. almost ready to go. just get the roof down so we can get all the volcanic ash in ourfaces — that's the plan. i've seen some other active volcanoes — hawaii, new zealand — so it would be nice to see. this rally is described as an opportunity to take the road less well—travelled but add in a giant volcano and it becomes a once—in—a—lifetime experience. tim allman, bbc news. you can get much more on all those stories under the bbc website or you can download the bbc news app. you can reach me on twitter — i'm @ rich preston i would love to hear from you. from all the team here in london, thank you for watching and see you next time. hello. saturday's cloud and rain moving south was only one part of the weather picture. the other was the strengthening wind, and close to this low pressure, northern scotland will get off to a stormy start on sunday morning. there could be some travel disruption, as severe gales move through, and still some outbreaks of rain, whereas much of the rest of the uk, although it is still breezy, will get off to a dry start. cloudy skies in the west, and it's mild, temperatures around 6—11 degrees celsius. just focus on the winds, though, on sunday morning, particularly across 0rkney and northeast scotland, here some gusts 60—70mph here, maybe a little bit more exposed coasts and hills with some large waves on some of the coasts as well. so some disruptive strong winds to begin the day. slowly easing as the day goes on. still a few showers moving through here. maybe one or two showers with the cloud across the western side of the uk, but most places, as high pressure begins to move in, will have a dry sunday. the best of any sunny spells in the east. these temperatures are a little down on saturday's readings, but still on the mild side of average. now, as we go on through sunday evening and night, we will find some clear spells through eastern parts of scotland and down the eastern side of england. and this will allow for a touch of frost in the coldest spots, as temperatures drop close to freezing. we will keep the cloud in the west. the temperatures hold up here, and it is a mainly dry night to come. we have another weather system coming our way. this area of low pressure, the weather fronts around it, and it will gradually take this weather front southwards across the uk. it will take a lot of the week to do so. it will slowly bring in some outbreaks of rain across northern ireland on monday, into scotland, especially the north and west. could see some reaching into parts of northwest england and wales as well. whereas the rest of wales and england will stay mainly dry. some sunny spells in eastern england, around 11 celsius here, feeling rather chilly. whereas in belfast, up to 1a celsius. the breeze freshening again across northwestern areas. here comes the weather front slowly moving southwards as the week goes on. but we will maintain a west or south—westerly flow into the uk. so for the week ahead, things are looking mild. you will notice that on the temperatures here. a lot of cloud around, a few sunny spells, and again, some outbreaks of rain very gradually spreading southwards as the week goes on. this is bbc news, the headlines: around 100 people have died after a massive explosion when a fuel tanker collided with a lorry in sierra leone's capital, freetown. fuel spilled before
