this is bbc news. i'm martine croxall. the headlines at 11:00 — police make another arrest and say they've "got hold of a large part" of the terror network surrounding the manchester bomber. these arrests are very significant. we are very happy we have got our hands around some of the key players we are concerned about. there is still a little bit more to do. with the security level at critical, armed police are in force at the start of the bank holiday weekend — with more than 1,000 public events taking place. also this hour, an election row asjeremy corbyn links british military intervention abroad to terrorist atrocities at home. the conservatives call his comments crass and ill timed — but the labour leader insists there must be a new approach to foreign policy. we must be brave enough to admit that the war on terror is not working. we need a smarter way to reduce the threat from countries that nurture terrorists and generate terrorism. jeremy corbyn has said that terror attacks in britain are our own fault and he's chosen to do that just a few days after one of the worst

terrorist atrocities we have experienced in the united kingdom. an influential think tank accuses both the conservatives and labour of not being honest with voters about the consequences of their economic plans. and on newsnight, was this the week that changed the election? we talk to the man that invented the swingometer, david butler — who tells me the move in the opinion polls is bigger than any he's seen in 70 years. good evening and welcome to bbc news. britain's top counter—terrorism officer says they have captured "a large part" of the network involved in the manchester arena attack, where 22 people died.

mark rowley said "immense progress" had been made in the investigation — but there were still important lines to pursue and arrests to be made. he also disclosed that police have reviewed security arrangements at more than one thousand events around the country this bank holiday weekend. he said people should "go out as planned" and be "reassured by the greater police presence". our home affairs correspondent daniel sandford reports. an already vast investigation, still expanding. each day, counter—terrorism detectives raid more properties in manchester, cutting through the shutters at this moss side barbershop. the shop owner, abs forjani, is a cousin of the manchester bomber who was arrested earlier in the week, with two of his brothers. police also raided another house in the middle of the night, bringing the number of people in custody to nine, all men, mostly libyan, and aged between 18 and 38. they're very significant, these arrests.

we are very happy we have our hands around some of the key players we are concerned about. there is still a little bit more to do. the bomber, salman abedi, came back to manchester from libya last week. renting a flat in this block, he had already bought many of the ingredients for his lethal device. it was here that salman abedi spent his last weekend, putting his bomb together, making the final preparations to attack a concert full of teenage girls. about three months earlier, before he went to libya for the last time, abedi rented a flat in this block, being pored over by forensics officers this week as a possible bomb factory. the flat is owned by aiman elwafi. this evening, his friend told the bbc what aiman found after abedi had left. a piece of metal in the bathroom and electricity switched off, fire alarm is switched off. he can smell a strong, strong, strong smell coming out from the carpet.

aiman told me, i think it's like diesel, like petrol, something chemical. detectives say they've made very significant finds and, crucially, believe they have captured a large part of his terrorist network. we have seized thousands of exhibits which are now being assessed. i think it's fair to say there has been enormous progress with the investigation but still an awful lot of work to do. police have found bomb—making material, but because of concerns about what might still be out there, the threat level will remain at critical. the public can expect much higher security at the 1300 events in the uk this bank holiday weekend. we mustn't let this terrible terrorist incident impact on our lives. let's carry on this weekend, this bank holiday weekend, with our families and friends. a weekend in which armed officers will be patrolling on trains. detectives investigating monday's shocking attack

are growing in confidence, but for now, going into one of the most important weekends of the summer, everyone remains nervous. daniel sandford, bbc news, manchester. jeremy corbyn has placed tackling terror at the centre of an election campaign speech, his first since monday's bomb attack. he declared that the war on terror is not working — and pledged to change british foreign policy if labour were to win the election, to reduce the threat to the country. political opponents have criticised the timing of his speech, as well as his message. 0ur political correspondent vicki young's report contains flash photography from the start. jeremy corbyn knows that this is a sensitive time. after a terrorist atrocity, the labour leader restarted his election campaign today, joining a silent tribute to manchester's victims. but the labour leader didn't backtrack from long—held views on foreign policy, making his case that it's time

to do things differently. many experts, including professionals in our intelligence and security services, have pointed out the connections between wars that we have been involved in, or supported and fought in, in other countries, such as libya, and terrorism here at home. that assessment in no way reduces the guilt of those who attack our children. stressing his patriotism, mr corbyn repeatedly emphasised that nothing excused monday's massacre. and he had a direct message for britain's soldiers. i want to assure you that under my leadership, you will only be deployed abroad when there is a clear need, and only when there is a plan that you have the resources to do yourjob and secure an outcome that delivers lasting peace. mr corbyn promised that a labour government would give the security services the money they required, and cuts to police budgets would be reversed.

the issue of security could dominate the rest of this election campaign and todayjeremy corbyn has repeated views he has held for decades that military action abroad has made the uk less safe. but to others, that sounds like an excuse for terrorism. senior conservatives have been quick to hit out at the labour leader, calling his speech monstrous. this has been caused not by us, asjeremy corbyn would have us believe. it's been caused by a sick ideology, a perverted version of islam, that hates us and hates our way of life. to say anything now to legitimate orjustify those who have carried out the atrocity in manchester is, in my view, absolutely obscene. the arguments have returned and so have election photo opportunities. the snp leader condemned the manchester attack but said politicians shouldn't shy away from debate. bombing campaigns, whether in syria or libya, without a coherent strategy to tackle the underlying

problems there, often hinder rather than help those situations. these are the things we need to debate, and debate vigorously. this evening, mr corbyn faced more questions, this time on nuclear weapons. why would the british people want their leader somebody who supported their leader somebody who supported the ira? what i want is decency and human rights and peace process. i never met the ira. 0bviously did meet from sinn fein. how a country protect its citizens is likely to be high on the agenda for the rest of this election campaign. vicki young, bbc news, westminster. all of those who died in monday's attack have now been named. the 22nd victim was 15—year—old megan hurley —

she was from halewood in merseyside. danny savage reports from manchester now on a community grieving for lost family and friends. in central manchester today, people queued to buy flowers in remembrance of strangers. many are at a loss about what's happened — but have to do something. it was inconceivable to try and understand how the families are feeling, especially of the children. it's just shocking. i've been a coronation street superfan my entire life. 29—year—old martyn hett was one of those murdered on monday night. the outgoing coronation street superfan was well—known online. as these possibilities got less and less and less, you still had some hope there would be something. and when you actually got the call that actually confirmed that he had died in this terrible explosion, it's indescribable. your world just collapses, terrible. the final and 22nd

victim to be named today was 15—year—old megan hurley. her brother was seriously injured too. a note on the family business only hints as the true enormity of the tragedy. a picture of the horror which faced the first responders has emerged too. 0n the right, here, is paramedic adam williams. he is worried about the long—term effect on him and his colleagues. that is a big concern for all of us. possibly myself, there will be some permanent scars there, emotionally. and i do worry that my colleagues will suffer the same. there is a very sombre and respectful atmosphere here. it may be four days since the atrocity, but that really is just the blink of an eye, and people here are stilljust trying to come to terms with what happened and coming to pay their respects. 22 lives lost, countless

others changed forever. families left with just memories of those who will never come home. danny savage, bbc news, manchester. the executive editor of the new york times has told the bbc that he has no regrets over the paper's decision to publish photos of the manchester bomb scene. british authorities temporarily halted intelligence—sharing with law enforcement agencies in the us following the leaks by the american media. in an interview with the bbc‘s stephen sackur, dean baquet insisted his paper did nothing wrong in publishing the photos. actually, it was not at the highest level of secrecy. it was at a level of secrecy that made it much more widely dispersed than people acknowledged. it was not a confidential secret. police were concerned, it was totally

confidential. there were different levels of confidentiality and it was not at the top. they said the revelations undermined their investigation and not only that, they also undermines the confidence of victims, witnesses and their families. are you now prepared to say sorry? families. are you now prepared to 0 families. are you now prepared to say sorry? no, absolutely not, no. they have given no evidence that illustrates how this undermines the investigations. this is the kind of standard information that has been made public after terror attacks since september 11. if you look at everything from the boston bombing to september 11, a picture of a backpack, nobody has ever offered any evidence that got in the way of investigations. the british press and american press have different attitudes here. you tend to believe what the authorities say right away.

we have never heard anything from the victims. i have been answering letters from people... you mean in england? i've heard from no victims, none. no regrets. the executive editor from the new york times. let's have a look at some of the other stories making the news. they said mr corbyn's plans for policies didn't work. a student who made a bomb filled with ball bearings and left it on a tube train has been jailed for 15 years. damon smith put his homemade device into a rucksack and left it on a jubilee line

train in october 2016. the 20—year—old claimed it was a prank but was found guilty of possession of an explosive substance with intent. irish police are investigating the death of a baby girl who was left in her father's carfor several hours. it‘s. thfigmht efififzyleu-fi of the year. sir cliff richard and south yorkshire police have settled a legalfight over reports naming him as suspected sex offender. the singer sought damages from the force, and the bbc, over media coverage of a police raid on his home in 2014. he was investigated over historical sexual assault allegations, which he denied. the case was dropped last year and south yorkshire police has apologised wholeheartedly. the bbc is still disputing the singer's claim for damages. that's a summary of the news, newsday is coming up at midnight — now on bbc news it's time for newsnight. was this the week that changed the election?

we talk to the man that invented the swingometer, david butler, who tells me he's never seen anything like it. anything may happen. the movement of opinion recorded in the polls is a bigger movement that has occurred in any previous election. and our panel is back to make sense of an extraordinary seven days. donald trump's time abroad comes to a close. butjust what is awaiting him at home with the russia investigation? it would be a terrible thing if someone who was president of the —— president of the united states knowingly profited of laundering money for criminals. it would be even worse if the president of the united states' business profited of laundering money for the russian state.
