this is bbc news, i'm ben bland. our top stories: tracking down the terror network surrounding the manchester bomber. uk police say they have made immense progress. they're very significant, these arrests. we're very happy we've got our hands around some of the key players that we're concerned about. like i say, there's still a little bit more to do. more details emerge about salman abedi. a formerfriend told the bbc his behaviour had changed in the last six months. funerals in egypt for the coptic christians killed in an attack on friday. the country retaliates with airstrikes on libya. and a glimpse into the past. the bbc is given exclusive access to historic footage that has not been seen in 80 years. 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. a 44—year—old man was taken into custody friday evening on suspicion of terrorism offences. it brings the total number of men under arrest over the attack to nine. our home affairs correspondent daniel sandford reports. 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. his friend told the bbc what aiman found after abedi had left. a piece of metal in the bathroom, and the electricity is switched off, the fire alarm is switched off. and he can smell a strong, strong, strong smell coming up from the carpet. and aiman told me, i think it's like diesel, like petrol, something chemical. detectives say they have 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 that there's 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 1,300 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. more details have been emerging about the bomber salman abedi. the bbc has spoken to a former friend who said abedi's behaviour had changed in the last six months. our special correspondent ed thomas reports. the manchester home, the family, and the need to know why. ramadan abedi, a father who allowed his children to fight on the front line in libya.

his son hashim, suspected of supporting so—called islamic state. and then, salman abedi, the suicide bomber who murdered in his own city. i met him at a mosque, and we just prayed, and that was it. he stayed after for a bit, extra 5—10 minutes. this is his friend. they played football together, supported manchester united. now, he is too scared to show his face and says, over the past six months, salman abedi changed. there was something up. you could tell that there was something up with him, like, something was bugging him. then it came to a point where he didn't really listen to music anymore, didn't think about girls. if there was a nice track on, i'd be like, oh, this is a good song. he'd be like, nah, man, turn it off. shouldn't listen to music, it's the devil. he goes, even if you're to do bad stuff, and like sell weed or do whatever, like, even drink alcohol, as long as you're praying, just pray and just keep it up,

because you still can get forgiven, but like, just ‘cause he knows himself, doing what he did, he'll go to hell. so i don't know why he did it. the bbc has been told salman abedi fought in libya against the gaddafi regime when he was just 16. he wasn't alone. alongside him, his brother hashim. young men, guided by their father, ramadan. ramadan was a ferocious fighter. he was a good fighter. he was fighting to die, let's say. this man met all the three of the abedis in libya in 2011, and fought on the front line with ramadan abedi. so—called foreign fighters in the manchester brigade. 70% of them were from north of england. the people who went to fight in libya? yes. and did the security services ever try to stop you from going? from leaving this country? no. even though they can see what we're taking. ambulances, satellite phones, some people even brought in laser—guided, you know, laser sights. the bbc has also learned of allegations the manchester

bomber‘s father met the radical cleric abu qatada in london. and on facebook, he is alleged to have praised fighters affiliated with al qaeda in syria. he denies supporting islamic extremism. he believes, and a lot of libyan, and even arab and muslim here, they don't believe you can be a good muslim and british citizen. nasser knew ramadan abedi. he said fighting in libya changed him. he believes in thejihadi values, and if you see what he's thinking about libya, what he's wrote about libya, it's really clear. he believes injihadi. since the manchester attack, the bbc has asked for an interview with trustees of the mosque where the abedi family prayed. today, we were invited in. did anybody report this young man to counterterrorism police? yes, yes indeed. one of our imams had reported this person. we were not aware. it was a private matter.

the imam did not tell anybody inside this mosque? he did not tell anybody inside the mosque. that has got to be a worry. it has got to be a worry because, obviously, we as trustees, should, i suppose, know what is going on. you suppose? the reason i say "suppose," if he has reported him, because he had information we do not, and it's between him and the counterterrorist police. so i've not really spoken to him since. but he has said it to us. you've not rang the imam who noticed salman abedi first, to find out more information? i don't have any information, i don't need any information, because i am not responsible. when he passes the responsibility on to the counterterrorist police, who of course, as we all know, have been carrying out surveillance on the suspect. so it's not my responsibility anymore. it has been shifted to the police and to the security services. counterterrorism investigators will not comment if any warnings were sent, if salman abedi

could have been stopped from taking 22 lives. ed thomas, bbc news, manchester. let's take a look at some of the other stories making the news: don't die, stay alive — that is one of a number of frantic messages received before the sewol ferry sank off the coast of south korea in 2014, killing 30a people. the text messages are among data recovered from at least two mobile phones salvaged from the wreck, and are providing investigators an insight into the victims‘ final moments. most of those on board the ship were teenagers on a school trip. anti—government protestors in venezuela have been met with tear gas and water cannon in the latest demonstrations across the country. protestors were trying to reach military points in several cities, hoping to appeal to the armed forces who support the government of president nicolas maduro. chile's president, michelle bachelet, has marked the start of construction for a billion—dollar astronomical observatory high in the atacama desert, an area known for its extremely dry climate and clear atmosphere. when complete, in 2024, the aptly

named extremely large telescope will be five times bigger than the largest current observatory. astronomers say it has the potential to transform our understanding of the universe. egypt's air force has carried out airstrikes in libya, targeting jihadists in the east of the country. it is after an ambush in which at least 28 people were killed south of cairo. egypt's president, abdel fattah al—sisi, said the strikes were in retaliation for the militant attack on a bus carrying coptic christians. president sisi said those behind the shootings had been trained at camps near the eastern libyan port of derna. from cairo, 0rla guerin reports. the bus in which so many were robbed of life, on their way to an ancient monastery. the broken windows and scattered belongings testament to an attack that was merciless and highly coordinated. there were multiple

gunmen, who escaped across the sands in three off—road vehicles. relatives of the dead told the bbc the authorities should be doing more to protect christians, who are obviously at risk. this was the scene just last month, after church bombings in northern egypt. a nationwide state of emergency was announced, and security was stepped up. but many coptic christians say the authorities provide more lip service than proper protection. dozens of church—goers have been killed in recent months by the so—called islamic state. it says that christians are its favourite prey, and has vowed to keep up the attacks. and, as well as the new threat from is, many believers here complain of an older problem. discrimination.

among members of egypt's christian community, the largest in the middle east, there is anger and fear, and once again, there is grief. 0rla guerin, bbc news, cairo. leaders of the world's leading industrial nations, the g7, have agreed on new action to counter terrorism. at a summit in italy they called on internet companies to do more to stop the spread of hateful extremist content online. but the leaders were unable to reach an agreement on climate change — with differences remaining between us president donald trump and the rest of the group. the bbc‘s james landale is at the summit. at this summit, in an ancient town on the coast of sicily, there has been some harmony between the g7 leaders, above all, on the need to do more to tackle global terrorism. but there have also been some dramatic and discordant notes on

trade and climate change. donald trump has voiced his anger at the impact that he believes free trade is having on us car market is, and he has also expressed doubts about global warming, and threatened to pull the us out of a deal agreed in paris in 2015, to limit carbon emissions. so g7 leaders are using this summit to try to stay the president's hand. and they are not alone. in an interview with the bbc, the secretary general of united nations said the us had to pay engaged in the us paris climate accord. if the us withdraws, it is one more reason for all the countries to come together, to stay the course, and to make sure that the course, and to make sure that the paris agreement moves forward. we think it is very important that the american government stays engaged. but this is not the end of the world. i mean, independently of the world. i mean, independently of the position that one government

might have, independently of what the country involves, and the us is very important because of its dimensions, all the others should stay the course. mr trump's advisers say his view on the paris deal are revolving, but so far no agreement has been reached. the italian prime minister said the issue was still hanging. this summit has been literally overshadowed by the ancient volcano mount etna, but for many world leaders here, this is the first time in the world stage, and inevitably the focus was on one in particular. donald trump. and the overriding aim of the summit is to keep the president on side. convincing him that it is worth his while to be a member of this small clu b while to be a member of this small club of large nations. so they may push him on climate change, but not that hard. stay with us on bbc news.

still to come: rough and tumble. the us politician who won an election just hours after being charged with assault. in the biggest international sporting spectacle ever seen, up to 30 million people have taken part in sponsored athletic events to aid famine relief in africa. the first of what the makers of star wars hope will be thousands of queues started forming at 7am. taunting which led to scuffles, scuffles to fighting, fighting to full—scale riot as the liverpool fans broke out of their area and into the juve ntus enclosure. the belgian police had lost control. the whole world will mourn the tragic death of mr nehru today. he was the father of the indian people from the day of independence. the oprah winfrey show comes to an end after 25 years and more than a500 episodes. the chat show has made her one of the richest people on the planet. geri halliwell, otherwise known as ginger spice, has announced she's left the spice girls. i don't believe it, she's the one with the bounce, the go, the girl power. not geri, why? britain's top counter—terrorism

officer says they've captured ‘a large part‘ of the network involved in the manchester arena the egyptian president says the military have attacked a jihadist training camp in libya — following the deadly ambush of a bus carrying coptic christians. us republican greg gianforte has won a special congressional election in montana, just hours after he was charged with assaulting a british reporter. mr gianforte allegedly body slammed the journalist who asked him about healthca re legislation. the bbc‘s nick bryant has the story. often when politicians when election, they punch the air in delight. but it was a polite wave for greg gianforte, the republican accused of body

slamming a reporter. his a celebration doubled as a confessional. last night i made a mistake. and i took an action that they cannot take back. and i'm not proud of what happened. i should not have responded in the way idid. for that, i am sorry. and you are forgiven! this supporters may have forgiven him, but the police on the case, charging him with misdemeanour assault, after allegedly wrestling to the floor this reporter, benjacobs, from the guardian. donald trump had strongly endorsed gian fortes‘s candidacy. on a day after a little push and shove of his own with the president

of montenegro, the president expressed delight at the result. in the top gun testosterone—charged environment of a naval graduation ceremony at annapolis, for the next generation of america's military leaders, a timely reminder, perhaps, from mike pence, about the need for self control. i truly believe that commanding others first begins with commanding yourself. discipline is the foundation of leadership. staying with graduation ceremonies, hillary clinton was at her all—female alma mater, welsley college, landings some blows on donald trump, by recalling the nixon—era and 1969, the year she graduated. we were furious about the past presidential election of a man whose presidency would eventually end in disgrace with his impeachment for the obstruction ofjustice. as your representative,

you can count on me to fight back. but what a week for greg gianforte. a thumping victory, but also a body blow to this reputation. in kenya there's been a victory for an indigenous group know as the 0giek. they were evicted from their ancestral land in the mau forest decades ago but will now be allowed to return. the bbc‘s david wafula travelled there to meet members of the community. translation: i have lived here since i was born. i grew up here, married traditionally, had my family here, buried my husband in the forest when he died.

i don't know anything else. i live here with my great—grandchildren. the 0giek committee rely on the mau forest forest for food, medicine, shelter and the preservation of their culture. they live in homes on top of the many ridges spread across the forest. this is one of the few remaining homesteads of the 0giek people. they have been living here for centuries as hunters and gatherers. but the fear of being evicted from the forest is putting in question the existence of future generations. i took a walk with some of the villagers, to look at some of the activities they had in the forest, like bee—keeping. injuly 2008, the kenyan government launched a campaign to evict people living in the mau forest, including the 0giek, to try and protect one of east africa's most important watersheds. translation: when we realised all

was not well, we tried to protest. we were beaten, others were arrested. we realised it was not helping. so we decided to push for human rights. we went to the human rights headquarters in russia, and it gained momentum, that the 0giek community must be listened to. campaigners have pointed out that commercial farming has put the forest at more danger until this threat is addressed, this delicate ecosystem the 0giek rely on is in danger of degrading further. i , the prime minister of india has unveiled the country's longest bridge which can take to make connects to disputed states. china

claims the state as its own, and refers to the southern tibet. the bridge will help development of regions in the area as well is reducing travel time by a towel was. _by reducing travel time by a towel was. —— by eight hours. bbc news has been given exclusive access to historic footage filmed by young adventurers exploring parts of the world that were completely new to western eyes. some of these remarkable films, from the frozen mountains in the himalayas to the searing libyan desert, haven't been seen for a century. 0ur science correspondent, pallab ghosh. this is the first ever view of mount everest from the air. it was shot in 1933 by a group of pilots who risked their lives to help create an aerial map of the mountain. the film is part of the royal geographical society's archive. it includes the very first attempt to climb to the top of mount everest, in 1922. the climbers are treated to a ritual dance at a tibetan monastery. around the dancers' waists are aprons made from a lattice of human bones. the cameraman was captainjohn noel.

it was a new men simply camera... his daughter recalls how her father filmed the expedition. he had a purpose built tent he'd taken with him to base camp. and at night, using water from the glaciers and yak dung as a source of heat, he processed 10,000 feet of film on the mountain. conservation specialists are painstakingly restoring 138 films of some of britain's greatest explorations frame by frame. one of them is of a young army officer crossing the vast expanse of the libyan desert by motorcar. in 1932, ralph bagnold and his friends drove thousands of miles for weeks on end into the blistering heat. his son has read stories about these incredible expeditions, but it's the first time he's seen them. that's my father driving now.

he even wrote scientific papers about how sand moves. his research is helping space agencies to this day, to develop rovers that can drive across the surface of mars. to see this film makes me feel very proud of him. i'm in awe of what he managed to do. we can all now relive these extraordinary adventures, stories from a bygone age when the world held so many mysteries. and you can watch pallab‘s documentary "great explorations" here on bbc world news at 1.30am and 8.30am gmt on saturday. it will also broadcast on sunday and monday. don't forget you can get in touch with me and some of the team learning a language is a goal that many people aspire to. which one will you choose? and don't make

current events may play a role. what is the secret to having a real impact on government? for this white house i would say by rosetta stone and learn russian. he may have been joking about goings—on in the white house but there is a correlation between global politics in which languages americans learn. we haven't seen an uptick in russian classes just yet but when the soviet union was the enemy, the language was in demand. china's rise has been a number of american children learn the language. resident obama set a target of 1 the language. resident obama set a target of1 million. if our countries are to do more together around the world, then speaking each other‘s language and drooling understanding each other is a good place to start. —— are truly

understanding each other is a good place to start. in a decade after 9/11, arabic was the fastest—growing language being learned in the us. demand rose for passion and urdu speakers as well. but all pale in comparison. there are 45 million spanish speakers in the us already. the reality is that most americans don't learn a second language and hope that english is enough. plenty more on our website for you. that is it from me for the moment. i will be back with the headlines. hello.

with a bank holiday weekend now upon us, we are set to see a change in the hot, dry weather, that has been with us for the past few days. here was the scene on friday in moray. one of our weather watchers captured this. we will have similar conditions to start the bank holiday weekend. a humid start. more sunshine, but we are expecting to see some thunderstorms disrupting the sunshine. during saturday morning, we have this frontal system, this area low pressure, moving from the south and west, bring showers and thunderstorms across many parts of the country. for northern ireland, northern england, right down to the south—east, through saturday morning, we will see the showers. during the afternoon, there will spread further north across the country. they are bumping into the warm air in place. 30 degrees or so across northern and north—eastern scotland. lots of fuel for these big showers and the thunderstorms. could be showers mixed in. this is 4pm on saturday afternoon. thundery showers likely across central scotland, northern ireland, into northern england. to the south of that, a little fresher than it has been — we may still see temperatures in one or two spots up to around 20 degrees. so lots of sunny weather on the clouds, still, do because on saturday.

but the showers across northern parts of the country as we move through saturday evening and overnight. the odd rumble of thunder, here. but on into sunday morning, clearer skies across southern parts of the country. and it will feel a little more comfortable for sleeping through the early hours of sunday morning. temperatures will be down to 13 or 1a degrees. with a risk of some heavy downpours at times on saturday and late on sunday, there could be flooding on the road. perhaps spray around, poor visibility, if you have got plans to be heading off for half term holidays. during sunday, the next batch of showers will come in from the english channel. on sunday, you could see a chance of catching an odd thunderstorm. pretty hit and miss, and many parts of the country will have a drier day, with temperatures between about 16 and 26 degrees or so. but a chance on sunday night and then on to bank holiday monday, that we will see some of the showers becoming a bit more extensive. some uncertainty about their exact positioning. again, it looks like they will work gradually north and east across the country as we had through bank holiday monday. they will be hit and miss. not everywhere will get a heavy or thundery shower.

and it is a return to some sunny skies and the south. definitely not as hot as we get to bank holiday monday. a cooler and fresh outlook as we have through into the course of tuesday and wednesday. have a good weekend. this is bbc news. the headlines: british police have arrested another person in connection with monday's suicide bomb attack at a concert in the city of manchester. nine people are currently being detained, and the chief counter—terrorism officer said most of the network believed to be linked to the bombing had now been detained. egypt's air force has been in action in libya, targeting jihadists in the east of the country. egypt's president, abdel fattah el—sisi, said the strikes were in retaliation for a militant attack on a bus carrying coptic christians.

at least 28 people were killed in the ambush, south of cairo. the united nations secretary general says the paris climate change agreement will not collapse if president trump does as he has threatened and withdraws the united states. antonio guterres, speaking at the g7 summit in italy, called on donald trump to stay engaged with the agreement. now on bbc news, click.
