who were attending the event, some have spoken to local media, again not verified by the bbc at the moment, but some kind of talking about their confusion of finding out what was happening at the time. as you can imagine, thousands of people at the event in the market square of the city, lots of music playing, it must have been incredibly confusing, and then incredibly distressing for these people. we are talking about the statistic, but a human impact for those attending the event tonight. bjorn boch is the deputy editor—in—chief of the local the newspaper, the solinger tageblatt. he described the scene. there was chaos in front of the stages. people were like running away from the scene. many were very calm, so we didn't have a panic. but it was shocking. everybody who had to

say that, i can't imagine what that was like. and to get all the latest developments on this story you can scan the qr code on the screen to find our bbc news live page. we will update you on the latest developments there. it's been a week dominated by the democratic national convention, where kamala harris accepted the party's nomination, but today, it's an independent presidential candidate making headlines. robert f kenneder announced on friday he is suspending his campaign.

mr trump said kamala harris�*s swift rise to the democratic nomination is further evidence of the supposedly rigged system that robert f kenneder ran against. tonight i'm very pleased to welcome a man who has been an incredible champion forcing many of these values that we all share, and we have shared them for a long time. i don't think too many of you people have heard of him. he is very low key. he's a very low key person. he is highly respected. he is a great person. i've known him for so long. for the past 16 months. robert f kennedyjunior.

# there goes my hero. # there goes my hero. # watch him as he goes. # there goes my hero. mr kennedy's announcement comes a day after kamala harris officially accepted the democratic nomination for president, on the final night of the democratic national convention. joining me live is faiz shakir, a democratic strategist and chief adviser to senator bernie sanders. very good to have you with us. faiz, the mood at the dnc was buoyant. do you think that is resonating across the country and with 75 days to go, can the harris campaign keep it up? if you look at the polls, she has consolidated the democratic base and moved into strong

contention in all the battleground states. in fact, all of those states indicate she is slightly ahead. so she comes out of the convention probably with a bit of a bump from what you described as the buoyant mood. having introduced herself to more people who didn't know who she was coming into that convention. my worry would be, as we head into the final stretch after labour day in the us, it will be a few weeks until the election, and 5-6% weeks until the election, and 5—6% haven't made up their minds, they are undecided. how they decide in places like michigan, pennsylvania, wisconsin, in the final stages, will determine the outcome of the election. figs will determine the outcome of the election.— the election. as you say, the final weeks _ the election. as you say, the final weeks will _ the election. as you say, the final weeks will be _ the election. as you say, the final weeks will be crucial. if| final weeks will be crucial. if we look at what donald trump and his campaign are doing right now, they have been at the border, talking about those themes that he frequently alludes to, immigration, the economy, crime and so on. how much of a challenge do you think that is for the harris campaign? especially when it

comes down to how the voters, democrats, on those issues? if i was the harris campaign, my advice would be stay true to the message you know is going to win, and it isn't those issues you mention. number one, kamala harris has shown she is a strong and tough commander in chief, and a speech last night goes a long way to showing that. the prosecutorframework, that. the prosecutor framework, reassuring that. the prosecutorframework, reassuring people that when the tough decisions come, i have the steel to make them. the second issue that needs to be fleshed out, not immigration and crime, it's the economy. it's the number one issue facing a lot of people now, a major concern. the economic issues. kamala harris in the final stretch needs to tell an economic story about who she is taking on and who she is fighting for. she has been trying to do this with corporate greed and power

narratives, housing in america, pharmaceutical drug pricing. those are all popular but she has to continue to emphasise that as a point of contrast to donald trump.— donald trump. i'm sure you would have _ donald trump. i'm sure you would have seen _ donald trump. i'm sure you would have seen rfk - donald trump. i'm sure you would have seen rfk junior| would have seen rfkjunior dropping out. he'sjust been on stage with donald trump, endorsing him. his percentage of votes very much up for play. how do you think the voters will go on that? fin how do you think the voters will go on that?— will go on that? on the one hand, will go on that? on the one hand. it's — will go on that? on the one hand, it's not _ will go on that? on the one hand, it's not surprising - will go on that? on the one | hand, it's not surprising that he endorsed trump, if you look at his entire campaign, funded by republican donors, a bunch of money into it because they thought he could siphon votes away from the democrats and help donald trump. having realised kamala harris is in a very strong position, just goes ahead and endorses donald trump. the margins could matter a lot, it certainly does matter, but i think they recognise this is a play of weakness, because they see the

movement is with harris. we have a debate coming up, and that's going to be one of the major final stages of this campaign. a presidential debate, and a vice presidential debate. i think on those scores, harris is trying to explain to donald trump not only about the chaos, but economic things he is offering, for billionaires, trying to raise social security and medicare... she has to make the contrast of people dialling into the race late. something i wanted to _ into the race late. something i wanted to ask _ into the race late. something i wanted to ask you _ into the race late. something i wanted to ask you about - into the race late. something i wanted to ask you about as - wanted to ask you about as chief adviser to bernie sanders, his comment that caught my eye from tim walz. one person's socialism is another person's neighbourliness. do you think this campaign between harris and tim walz can rebrand progressive politics or do you think perhaps now that is too testing at a time when they are going up against maga voters?

come on harris and others talk about going after price gouging and corporate greed and abuse and corporate greed and abuse and exploitation, economists say, no, no, it's terrible economics. in fact it's very popular and it's the right thing to do, tim walz has showed that, that's what he is a very good pic in my view. in minnesota, he talked about freeing up workers, paid leave for workers, freeing up workers, paid leave forworkers, universal freeing up workers, paid leave for workers, universal school lunches for kids. those are really popular. there is a sense that when big money interests weighed in on this and said, no, don't talk about that, sometimes there is a flinch, and i would argue that the track they are on with tim walz is the right one. the friction with the corporate classes is fine, it's good, this is what sells two undecided voters that we are on the right track.—

the right track. very good to have your — the right track. very good to have your view, _ the right track. very good to have your view, thank - the right track. very good to have your view, thank you. i four prision guards were killed during a prisoner revolt at a maximum security penal colony in southwestern russia. russian special forces killed four rebelling inmates during a mission to rescue hostages. russia's federal penitentiary service says 8 prison workers and 4 convicts were taken hostage and the siege began during a disciplinary commission meeting. the bbc was unable to verify images like this one, showing one of the prisoners walking around the penal colony, armed with knives. during the attack, the insurgents took to social media where they indentified themselves as militants for the so—called islamic state. our russia editor steve rosenberg sent this update from moscow. this happened in a prison called ik 19, a maximum—security penal colony in russia's volgograd region. i say maximum—security, but somehow four inmates managed to arm themselves with knives and go

on the attack. so, they attacked prison staff and, having done so, they released pretty gruesome mobile phone footage showing prison officials lying in pools of blood. we believe at least four prison staff were killed. the attackers identify themselves as islamic state militants. they said they've taken hostages, too. russian special forces were deployed to the scene and later stormed the prison and ended the siege. all four armed convicts were shot dead. i remember something similar happening just over two months ago. in another prison in rostov on don. islamic state militants took hostages in a pretrial detention centre. russian special forces stormed the facility, ending the siege. talks aimed at achieving a ceasefire in gaza are ongoing in egypt, and will reportedly continue into a third week. president biden spoke over the phone

with egypt's president abdel fattah el—sisi on friday about the negotiations. us officials are deeply involved. cia director bill burns is currently cairo. his trip follows that of the us secretary of state antony blinken. israel is continuing to hit gaza with deadly raids. palestinian medics on friday said multiple people were injured as israeli forces shelled jabalia, people there said they were hit while fleeing the area due to idf evacuation orders. there was no immediate comment from israeli authorities on this incident. people remain in desperate need of food and water. food is being rationed in refugee camps where growing numbers of people ae sheltering. hamas has refused to directly take part in the current round of talks. the group accuses israel of

negotiating in bad faith. joining me live isjon alterman, former special assistant to the assistant secretary of state for near eastern affairs. also director of the middle east program at the center for strategic and international studies in washington, dc. jon, the us has said some progress is being made in talks in cairo but others don't seem so optimistic. what is your assessment of the prospects for a breakthrough here? i was talking to somebody in government today who has been following the negotiations. he says some people i was domestic, some are pessimistic. i have to say i am pessimistic. —— some people are optimistic, some are pessimistic. i don't see signs that netanyahu or sinwar have urgency for a deal, they are both digging in. i don't think the americans have figured out how to light a fuse under each side. netanyahu, there is a big incentive to just wait and see what happens in the election. us policy

could change profoundly. i want to talk more _ could change profoundly. i want to talk more about _ could change profoundly. i want to talk more about the - could change profoundly. i want to talk more about the kind - could change profoundly. i want to talk more about the kind of. to talk more about the kind of leverage washington might look at using. i also want to talk about some of the reported bones of contention in this. including what comes next for gaza. the israeli presence in gaza. the israeli presence in gaza. do you think as long as israel intends to have that overarching authority in the gaza strip, do you think they will be able to reach a deal? the israeli military believes that there are lots of capabilities the military has, that means it doesn't have to be physically there all the time, they can reserve the right to move in. they can seize territory, as indeed they say this philadelphi corridor along the egyptian border. they were told they shouldn't go there, and they took it in a matter of hours. the military feeling, a lot of this, you

don't require troops there, you require the ability to insert troops, but netanyahu insists the troops will stay. some in israel say that because netanyahu doesn't want to reach a deal. lots of reasons to think sinwar also doesn't want to reach a deal. each side thinks the longer this goes on, the stronger it is getting, the weaker its adverse areas are getting. weaker its adverse areas are cuettin. ~ weaker its adverse areas are iiettin _ . ., ~' weaker its adverse areas are iiettin, . ., ~' ., getting. we will talk more about washington, - getting. we will talk more - about washington, specifically president biden's legacy here. i'm sure in the final few months of his presidency, he would like to see a deal done. to borrow your words, you don't really believe the us has found a way to light a fuse under this. how do you think they could do that? and will they? there is a lot of potential leverage the president has, but his lame—duck status gets in the way. there's not really a sense that the president personally can hold netanyahu

accountable after, say, november orjanuary, and that's an obstacle. i'm told the president feels deeply, especially about the five americans still held in gaza, this is something he has committed to, but netanyahu seems to have calculated that his own political survival in israel depends on staying task. he's always been a cautious negotiator. he negotiated for five years over the freedom of gilad shalit, the israeli corporal who was kidnapped in gaza. —— depends on staying task. there is the possibility israelis will get impatient, thatis israelis will get impatient, that is really the avenue for change. it's not called from the white house, but it's israeli politics rising up and saying, now is the time to make a deal. ~ ., ., ., saying, now is the time to make adeal. ., ., ., ., . a deal. we also have to touch on what iran _ a deal. we also have to touch on what iran has _ a deal. we also have to touch on what iran has said, - on what iran has said, potentially watching to see what happens in all of this. if

there isn't a deal, what do you think we could potentially see from iran? also cognisant of the fact authorities there have said they will retaliate at a time of their choosing. potentially further in the future, what do you think we could see?— future, what do you think we could see? , ., , ., could see? there is no question there is all— could see? there is no question there is all sorts _ could see? there is no question there is all sorts of _ could see? there is no question there is all sorts of kindling - there is all sorts of kindling in the middle east. the west bank is getting more and more precarious. the lebanon border, where iran has proxies, his brother, which has 150,000 rockets and missiles to attack israel with. all kinds of iranian elements. what the americans have managed to do is they have delayed and possibly prevented an iranian strike, to prevented an iranian strike, to prevent the region from going into warfare. you also have the precedent that you have to send senior american officials to spend days and days in negotiations and you never really fix the problem. there is no question, the entire

region could erupt into warfare. the americans seem to have avoided that, but in terms of resolving the war, i don't think we are really very close. very interesting point. thank you for being with us.- you for being with us. thank ou. the world health organization has declared m—pox an international health emergency, as a new strain of the virus is rapidly spreading across parts of africa leading to a surge in infections. the head of the world health organization has said that plans to control the new m—pox outbreak will require at least $135 million over the next six months. in an address to who member states, dr tedros said the outbreak could be controlled but it required a comprehensive and coordinated international response. earlier the organisation told its partners they could start buying m—pox vaccines before it approves them, to speed up distribution. the democratic republic

of congo, the centre of the m—pox outbreak, is expected to receive its first doses next week, donated by the us and japan. our correspondent, merchuma, has been to burundi which has already confirmed more than 170 cases. at one of the largest medical centres in burundi's biggest city, staff here are battling to both treat the people coming into this facility, and to monitor how far and fast the mpox virus is spreading. translation: | had | swollen lymph nodes. it was so painful i couldn't sleep. then the pain subsided up here and it moved to my legs. but i am better now. they are currently treating 55 cases here. there are four suspected cases that just walked in, and their status will be

confirmed after a lab result. i'm just outside the men's unit, and normally you wouldn't see this orange or red tape here, but this is a form of isolating those who are being treated and the rest of the community that may walk in to seek services in this facility. burundi is seeing a surge in mpox cases. medical officials here are concerned about limited resources. there's only one testing laboratory in the whole country, insufficient testing kits and no vaccines. access to basic resources like water is also limited. translation: this is a real challenge. | the fact that diagnosis is only done in one place, this delays detecting new cases. health centres are calling the laboratory, saying they have suspected cases, but it takes time for teams from the lab to deploy to where the suspected cases are to take samples, and it takes even more time to release the test results. the epicentre of africa's

current health care crisis is neighbouring drc, less than 20 miles from here. what is crucial for health officials here in burundi is that people understand the dangers of this disease, but that hasn't got through yet and it will take time. public awareness about mpox is quite limited here. most of those we spoke to do not even know what it is. those who do are not aware that it is spreading in their country. this lack of awareness means that while, on one side of bujumbura town, efforts are being made to help those affected survive and recover, elsewhere, life carries on as usual. containment is difficult, making the need for an adequate vaccine even more urgent. merchuma, bbc news, bujumbura, burundi. us presidentjoe biden announced a new military aid package for ukraine worth $125 million on friday.

in a call, mr biden reaffirmed to ukrainian president volodymyr zelensky the us's "unwavering support for the people of ukraine". the anouncement comes after indian prime minister narendra modi met president zelensky in kyiv, and urged him to hold talks with russia to end the war. mr modi said he would act as a friend in his efforts to establish a truce. it comes after he made a trip to neighbouring poland on thursday. our europe correspondent nick beake sent the latest on prime minister modi's visit from kyiv. both prime minister modi and his host president zelensky have hailed today as being a really historic one. certainly we've seen over the course of the past two and a half years lots of western leaders coming to kyiv to show their support, but what the ukrainians are saying today is that this visit represents support from of the indian leader and the asian powerhouse that he controls.

a very different story from six weeks ago when a lot of people here in ukraine were really upset to see mr modi visit vladimir putin. in moscow, there was this warm embrace between the two men that came on a day when more than a0 people in ukraine were killed by a barrage of russian missiles. one of these missiles hit the main children's hospital here. i think no coincidence that first on the list of places for mr modi to visit today was this new art installation that doubles up as a memorial to the 570 children who were reported to have been killed since the start of russia's full—scale invasion back two and a half years ago. after that moment, mr modi said that his heart was filled with grief for the people he described as martyrs, those who had been killed. and shortly after that, he talked about this personal pledge he was making, playing some sort of role he hoped in bringing about peace between ukraine and russia, saying he was prepared to try and start

a process in which there would be negotiations. before we go, let's return to the breaking news from germany. police there have confirmed at least three people have been killed and at least four others injured in a suspected knife attack in the western city of solingen. local media is reporting a man randomly stabbed passers—by during a festival in the city centre on friday evening. the attacker is still at large, and police have launched a manhunt. police helicopters were seen above the city. celebrations were under way to mark the 650th anniversary of the city's foundation. the city authorities asked people to leave the area and police are imposing security cordons. stay with us here on bbc news. hello there. the weather's looking very mixed this weekend. yes, there will be some rain at times, temperatures a bit disappointing, but things are set to warm up into next week, especially for england and wales.

so, we will have some rain around at times this weekend, mainly across northern and western areas, though for saturday, it's the south which will bear the brunt of some of the wettest of the weather. will be quite mild to begin saturday in the south, a bit cooler further north where we have more clear skies. but outbreaks of heavy and persistent rain affecting much of the channel islands into central and southern england, southeast wales, up into the midlands and across into eastern and southeast england. we have a met office yellow warning for the far southeast of england because we could see in excess of a couple of inches of rain here. that could lead to some localised flooding, some standing water on the roads. has been very dry across the southeast, though, for all of august. so this is very much needed rainfall — a good drink for the gardens, but it will be very wet through the morning. eventually, it clears out into the afternoon and we should see sunshine and some heavy, maybe thundery showers moving in, too, but it does brighten up elsewhere across the country. it's a bright day from the word go with sunshine and showers, but disappointing temperatures —16—18 celsius. that is below par for the time of year. saturday night's dry,

quite cool, chilly for many, single digits across the board, but it will be turning a bit milder, wetter and windier out west as the next weather system starts to make inroads for sunday and you'll see more isobars on the chart. so it will be a breezy, blustery day on sunday, with most of the rain in the north and the west. so, quite a wet day, i think, for northern ireland, increasingly so for scotland, northern and western england and wales, maybe a few showers getting into the midlands. but i think the southeast quadrant tending to stay drier, closer to high pressure to the south, so could be up to 20 degrees given some brightness, but rather cloudy skies and again disappointing further north — mid—teens. that system moves away during sunday night into monday. it's a bank holiday monday for many. a ridge of high pressure will start to build in a bit more strong, stronger across the south, so i think england and wales largely dry. we should see some sunshine around, but another area of low pressure will bring more of a breeze. cloud outbreaks of rain to the far west of the uk, but temperatures responding up to 23 degrees in the south. and that's the sign of things to come for this upcoming week. it looks like summer will make

a return, especially for england and wales, where it could be very warm indeed, with one or two spots in the southeast perhaps touching the 30 celsius mark.
