start the beginning of next week with things settling down, showers will begin to ease with good spells of sunshine and it will start to feel warmer as we lose the northerly breeze. 22 people were hurt when it went off just before 8.30 this morning. none of the injuries are life—threatening. police say it was an improvised explosive device. it was left in a bucket, and the bbc understands it had a timer. massive bang occurred. didn't know what happened, looked around. the first thing you saw was an orange sort of fireball circumferencing the whole tube coming towards you. this fireball is just going over your head and eve rybody's screaming, and you just run out of the tube. the area is still locked down as police hunt for clues. there are many urgent inquiries ongoing, with hundreds of detectives involved, looking at cctv, forensic work, and speaking to witnesses. also on the programme:

north korea fires another missile overjapan, to international condemnation but no agreement what to do about it. the unions call for a pay rise of nearly 4% for some nhs workers. and a bittersweet end to a space mission which circled saturn for 13 years, sending never before seen images. and in sport: red bull surprise in singapore — with daniel riccardo and team—mate max verstappen setting the fastest times in second practice. lewis hamilton was third quickest in his mercedes. good evening and welcome to the bbc news at six.

i'm at parson's green station in london where, earlier today, a device partially exploded on a tube train, in what police have said was a "terrorist incident". thankfully, no—one died, but 22 have been treated in hospital, some suffering from burns. witnesses have spoken of a "flash and a bang" and then panic as commuters ran out of the carriage. the incident happened in the morning rush hour, just after 8am, as a district line tube train pulled into the overground station at parson's green in west london. the bbc understands that the bomb, described as a homemade device, had been fitted with a timer but it failed to fully detonate. whoever planted it is still on the run. in a moment, we'll be hearing from eyewitnesses and we'll have the latest on the investigation, but first tom symonds reports on the explosion here this morning.

at 8:20am, the friday commute was well under way. a packed commuter train, young, old, children, pensioners, everyone. at parsons green station, where the lines run overground, a brief stop. green station, where the lines run overground, a brief stoplj green station, where the lines run overground, a brief stop. i stepped on and within two seconds, a massive bang. loud enough to make me wonder what it was, and i looked around and this wall of fire was coming towards us. this wall of fire was coming towards us. i turned and i saw the fireball surged towards my side. you heard the loudest, scariest screams coming from what sounded like the carriage next to us. people shouted run, so we ran for our lives. it was

pandemonium on the platform, people falling down because everybody was trying to make an exit. i fell over somebody who had fallen in front of me but managed to get myself up. passing passenger pointed a phone back at the train. inside was this, still flaming, a white bucket with something inside. police later confirmed a makeshift bomb. get away and move down the platform. despite the explosion, the train appeared in ta ct, the explosion, the train appeared in tact, although the line was brought toa tact, although the line was brought to a halt and other trains is that you to as passengers to a halt and other trains is that you to as passengers were to a halt and other trains is that you to as passengers were to safety. hundreds were able to walk away, uninjured. but not all. on the street, the emergency response was under way. i have seen a woman stretchered off, and clearly her legs are wrapped up and she had burns to herface. she is conscious,

she was taking some oxygen and pain relief as well. but clearly, people have sustained very nasty burns. 29 people have been injured, most suffering from what police describe as flash burns. move back, thank you. the area around the station was cleared, sniffer dogs checking nothing was left to cause further harm, and another terrorism operation got under way. the investigation is being led by the metropolitan police counterterrorism command and part of the national terrorism policing network, and there are urgent enquiries, with hundreds of detectives looking at cctv, forensic work and speaking to witnesses. that work starts here. the first urgent task, to identify whoever put the bomb on this train. the advantage for the police is that these trains have cctv cameras, as do the platforms. they also have the

device pretty much intact, and its packaging. and they will also look for anything dropped by the suspects, which has happened in the past. beyond here, the intelligence services will want to know who did this, who they are in touch with, and whether anything else is planned. the government's emergency committee decided not to raise the national threat level, suggesting no further imminent attack has been detected, but security is being stepped up, again. people travelling in london will see an increased armed police presence on the transport network, and they will see security increased, and the police will do what is necessary to protect the public. there were injuries but no one was killed today. this could have been a lot worse. yet a bomb was placed unnoticed on the tube, demonstrating that warnings to be vigilant should not be ignored. as you've heard, i arrived here on the scene very soon after the device went off, just 15 minutes or so later.

all around me there were dazed, shocked and frightened people, many of whom had been on the train, including peter crowley, who was heading into work at a carpet shop near here. how are you feeling? i'm feeling fine. peter crowley has had a very lucky escape. he was standing right by the device when it went off on the packed tube train. he was hit by the fireball, leaving his head badly singed. wow. yeah. he was in shock. rather than go to hospital, he turned up to work, where i met him this afternoon. peter, how are you? very shaken up. lucky. you've been incredibly lucky. tell me what happened this morning. the train pulled up, doors opened, an explosion happened to the left of me against the doors which don't open, not the platform ones. fireball‘s come over my head, and panic set in. everyone's rushed from the tube,

it's been complete pandemonium. sojust explain. so you were on the tube. yes. you were standing, sitting? standing, leaning against the door, the open door, on my phone. all of a sudden i heard a massive explosion which was like a pressurised sort of sound, like a deodorant can or a kettle exploding, and this fireball. i've turned, the fireball‘s come up over the top of the carriage. and it was really that high? yes. i mean, from the pictures, i guess it come up from behind where the people were standing in front of those doors, and come up to the top. and you've got bad... is this from this morning? yes, i mean, literally, hair has come out today. that's your hair? that's what's happened ? yes. did it take you by surprise? as well as the burns to his skin, he realised his clothes have been left peppered with a white residue. it was just sheer panic, everyone rushing off the tube. the worst gentleman i saw,

he was being helped off the carriage by another couple of people. he had a pufferjacket, it had all melted on his back. he had burns across the front of his face. from what i see now, i believe that the flash came up from behind him, over his head towards myself at the doorway. and now, after all this, how are you feeling? shaken up, now i've heard that it was actually a planned explosion. lucky. i'll go home, give my wife and kids a big cuddle tonight, and happy to be here. he has now been to hospital and says he is determined to be back at work tomorrow. the head of counter—terrorism says hundreds of detectives are now involved in the investigation.

the bomb is being examined by forensic teams and officers are looking through cctv at the station for clues about who planted it. our security correspondent gordon corera takes a closer look now at the investigation and where it might lead. this device is at the heart of the investigation, and it will have provided police with many clues. one clue are the wires coming from it, almost certainly used to try to trigger an explosion. they look similarto trigger an explosion. they look similar to these christmas tree lights that a birmingham man planned to use in a home—made device before he was arrested. such improvised devices do not always go off properly. that was the case on the zist properly. that was the case on the 21st of properly. that was the case on the 2ist ofjuly 2005 when the underground was targeted. experts believe today's bomb also did not explode as intended. the size of the

device employed was quite significant. had it functioned in its intended and designed mode, we would have seen considerable casualties, many people injured, probably many killed. the explosive may have been a compound called ta tp. this footage from brussels airport and metro shows the devastation when it detonates properly. more than 30 were killed. it is also thought to have been used in the manchester arena attack this year, which involved a suicide bomber. but today's attacker wanted to get away, and used a time. that is similarto to get away, and used a time. that is similar to damon smith, seen here leaving a timed device at north greenwich a year ago, which was spotted before it went off. today, hundreds of counter—terrorism detectives have been employed in this investigation. they have been

fore nsically this investigation. they have been forensically analysing this device, looking for fingerprints and dna. they have also been scouring cctv images, looking for an individual carrying this bag onto the tube and then getting off without it. that will have been the starting point for their manhunt. mi5 are assisting the investigation. so far, officials have expressed caution about identifying a motive but they will wa nt to identifying a motive but they will want to know if the attack was part ofa group, want to know if the attack was part of a group, or acted alone. and, as has often been the case recently, if they were previously known to the authorities. unfortunately, it would not be surprising. the concept of a lone wolf now would more accurately be described as a no wolf. increasingly, attacks have been committed by individuals who were known in some way to either the counter—terrorism police or mi5 beforehand. officials here have reacted with irritation to this tweet from donald trump. "another

attack in london by a loser terrorist. these are sick and demented people who are in the sight of scotla nd demented people who are in the sight of scotland yard. must be proactive" . theresa may responded that it was never helpful to speculate about an ongoing investigation. for the fifth time this year, the country is dealing with the aftermath of a terrorist attack. this one could have been worse, but the urgent priority now we'll be finding whoever left the device, and making sure they pose no further danger. gordon corera, bbc news. daniel sandford is outside scotland yard now with the latest. when the police spoke earlier they we re when the police spoke earlier they were careful about not using the word "manhunt" but that is what they will be pouring their energies into now. absolutely, and in many ways the most intense manhunt seen in london since the failed terrorist bombings of the 21st ofjuly 2000 and five. once again, there is a

bomb maker on the loose, and somewhere there is a bomb—making factory, possibly containing dangerous ingredients, to be found. at the moment, detectives are trying to do that without releasing an image of their suspect, either because they do not have a good enough cctv picture, or because they hope to be able to catch them without resorting to a public appeal. there is, of course, relief here that nobody has been killed, but also a great concern that the bomber, or bombers, must be caught before they can strike again. in the midst of all this, the counterterrorism command are being distracted by mark —— above all people, the president of the united states of america, whose intervention was described today as both pure speculation and unhelpful. this area remains locked down. you

can rob lee still see the train on the tracks at parsons green station. but there are a lot of people around who realise that what happened today could have been a lot worse. back to you. north korea has fired a ballistic missile across japan, creating new tension in the region after its nuclear bomb test less than two weeks ago. the rocket travelled the furthest of any so far, more than 2000 miles from sunan, over the japanese island of hokkaido, and into the pacific ocean. it's sparked a new round of international condemnation but no agreement on how to rein in north korea's increasing provocations. rupert wingfield hayes reports from niigata in japan. siren wails in northern japan, friday began with this very unpleasant wake—up call. speakers blared out warnings. commuters were cleared from railway stations, and trains halted. that's a nice wake—up call.

foreign tourists were left bemused by what was going on. far above, a north korean missile was flying past. this behind me is the sea ofjapan. we've come up from tokyo because this is the place that is most affected. this is the place where this morning they were woken up by those sirens and by that message that a north korean missile was flying overhead. for the people who live here in towns and cities along this coast, it is the second time that has happened in less than three weeks. this afternoon, we found this man playing with his young daughters and fretting about how to protect them. translation: i want to protect my kids but we don't have a basement. we have nowhere to hide. the missile takes only ten minutes to reach japan. what can we do in ten minutes? erica told me she is frustrated by japan's refusal to talk to north korea.

translation: the sirens, to scare people, there's nothing you can do. so what is the point? the government needs to have a real policy. it needs to talk to north korea. this is the type of missile that is thought to have been fired. it flew further than any north korean rocket has ever gone before. in tokyo, prime minister shinzo abe marched out to face the cameras again. "if it continues down this road", he said, "north korea will have a dark future". but his words have an increasingly hollow ring. beneath this house, one person has taken matters into his own hands. behind a heavy steel door, he takes me into his own nuclear bunker. translation: since these missile launches began,

i've had so many calls about the air filtration system. i've had at least 800 enquiries this year. he is safe in his bunker, but the rest of japan is wondering what it can do, and when the next missile launch will come. rupert wingfield hayes, bbc news, niigata, northern japan. our top story this evening. a manhunt is under way after a home—made bomb exploded on a london tube train this morning. and still to come... the ballet stars gathering for a special gala in the city where they first learnt to dance — hull. and in sport on bbc news: we look ahead to "the real deal" — as gennady golovkin and canelo alvarez battle it out to be seen as the best pound for pound boxer in the world. it's given us some of the most

remarkable images ever seen of the planet saturn, its rings and moons for 13 years. but earlier today, the final mission of the space probe cassini was to plunge into saturn's atmosphere to be burnt up and destroyed. during its epicjourney encircling the sixth planet from the sun, it documented extraordinary discoveries and gave unprecedented insight into the workings of this most mysterious of planets. our science editor david shukman has more. it has been a journey that sounds like something from science fiction. nasa conjuring up animations of the cassini spacecraft line around the spectacular rings of saturn. but this really did happen and these are some of the images the mission actually captured. the planet seen

from closer than ever before. the strange detail of its rings. ajet strea m strange detail of its rings. ajet stream in the shape of a hexagon. and an utterly weird collection of moons. but today, the expedition had to come to an end. i'm going to call this the end of mission. at mission control in california, hugs and applause. for many it has been the work of a lifetime, and no surprise there were very mixed feelings as there were very mixed feelings as the final signal reached earth. well, it has been a part of my life for 20 years. we have spent a day in and day out thinking about cassini, planning the observations and focusing on the signs. my career has been based on cassini so it is ready ha rd to been based on cassini so it is ready hard to see that go. saturn is the most distant world to have been explored for so long, and the cassini spacecraft, which is almost as big of a bus, has achieved

something never attempted before. it has given us unprecedented views. these have led to dozens of discoveries. the mission is described as one of the most remarkable journeys of exploration. it has been orbiting saturn for a staggering 13 years. it is one of saddam's moons which have provided the most startling revelation. plumes of vapour were spotted coming from it. this turned out to be water. let's take a closer look inside. we now know under a covering of ice there is a notion. scientists have come to an amazing conclusion that in here there is every ingredient needed for life. this opens up a whole new realm of possibilities in the search for life beyond earth. and the discovery of conditions on moons like this is a real breakthrough for scientists like linda spilker who started her

career at nasa three decades ago when the mission began. we wanted to know was their life in insider does's ocean. could there be life inside other moons? it will take future missions to go back and find a nswe rs future missions to go back and find a nswers to future missions to go back and find answers to those questions. the mission captured images of the moon titan. and the sounds that it recorded. to make sure cini would not contaminate other worlds where there may be life, it was sent to its destruction, but has raised tantalising possibilities. the pressure on the government to lift its 1% pay cap on public sector workers has intensified after 14 health unions called for a rise for more than a million workers in the nhs. in a letter to the chancellor, the unions — representing nurses, midwives and ambulance workers — are calling for a rise of nearly 4%. the government has said it wants their pay to be fair but also affordable to taxpayers. our health editor hugh pym reports. diane, who is a laboratory technician has worked in the nhs in hull for more than three decades. but the last few years have been the toughest because of the pay cap. she has had to cut back

on her shopping and watch very closely what she spends on herself and her daughter. it's definitely not fair. it makes is all very angry, all public sector workers should have the cap lifted. we alljust as important, we will work as front—line workers, we are all the cogs in the wheels that keeps going to make the nhs work. "scrap the cap" has been the call from nurses and other public sector workers protesting against the policy limiting annual wage rises to i%. earlier this week, the government lifted that limit for police and prison officers. health unions want to know what their unions can expect. nhs staff say pay restraint has seriously undermined morale. we're being so undervalued, it's a unique skill set, nursing. to be able to smile at someone who has just thrown a commode at you, or to be able to offer care in someone's darkest moment, and being told with worth less

and less, and less every year, carrying on with that is really difficult. here is how the pay cap imposed after 2010 impacted nurses and midwives. average annual wage rises in britain have been under 1% since then. that was well below the inflation rate for much of that time. employers did not comment on the specific wage increases demanded by unions, but in a significant move, one group representin hospitals and other trusts in england said it was broadly sympathetic to the unions‘ claim, because of current difficulties recruiting and retaining staff. i think it is absolutely understandable that the health unions have called for an end to the pay cap. we've seen austerity now biting for the past seven years, and it's absolutely critical that we see that pay cap lifted so that we get enough staff on the front line, and we keep those staff that are there. a government spokeperson said

the priority was to ensure the overall package was fair, while also being affordable to taxpayers. ministers say they will do what they can with the limits imposed by budget pressures. but they know that across the nhs, there is real passion about getting more pay. hugh pym, bbc news. the world's top ballet dancers are gathering in hull today for a special gala performance — these are the rehearsals. the principal dancer of russia's prestigious mariinsky ballet, the head of the royal ballet, and the principal of the english national ballet will be there. they all followed similar paths to stardom — beginning their careers at a small dance school in hull, as our arts correspondent, david sillito reports. classical music i think it's a very special day for hull and for the dance world.

nice to be back here. how long since you were last here? it must've been when i was a little kid. before i went to the royal ballet school. this is the story of ballet and an extraordinary homecoming. our young ballerinas are following in extraordinary steps. joseph caley is now a dancer with the english national ballet. and it's not justjoseph, the royal ballet's artistic director and choreographer, they all started out here. right leg, left leg. i went to skelton hooper in hull. that's where i started to do ballet. it kind of has, you know, these pink walls in brick. so many fellow stars began here in this little side street in hull with vanessa hooper. robert, remember this?

xander parrish was just eight when he first arrived, he is now the first ever british principle of russia's mariinsky. i simply can't believe it, i get to see all my beautiful babies. all back together again. all grown up, all dancing together. when you stand on that stage, what are you faeling? i think my heart will burst with pride. and there will probably be tears running down my face. but ijust feel so grateful that i have had the opportunity that they have had the opportunity, and we can show it together. and this is kevin o'hare, head of the royal ballet, anotherformer student. and this is his grand gala. a celebration of ballet, and all that began here. wonderful! time for a look at the weather. here's lucy martin. good evening. the showery theme

continues as we move through the evening. we will continue to see a few coastal showers overnight. a chilly night to come. temperatures falling to 10 degrees in towns and cities. rulli, a few degrees cooler than that. there will be a lot of dry weather to start the day tomorrow. a few showers persisting along the coast. the cloud bubbling up along the coast. the cloud bubbling up and showers becoming more widespread as we move through the day. still a northerly breeze so temperatures around the same as we have seen today. tomorrow night will bea have seen today. tomorrow night will be a fairly chilly night with the winds easing. we will see the shower is fading and temperatures will fall away. rulli we could get close to freezing which means some of us could wake up to seems like this on sunday morning. a touch of grass frost is not out of the question. plenty of brightness around as we start the day on sunday. staying dry with good spells of sunshine. there

is just the risk of seeing a shower into the afternoon, particularly the further south and east you are. temperatures feeling warm with lighter winds. that is how we start the week, settling down with sunshine. we will lose the northerly breeze. thank you. that's all from the bbc news at six, but there's continuing coverage of the terror attack on the bbc news channel. now on bbc one we nowjoin the bbc‘s news teams where you are. a manhunt is on the way to find the person responsible for setting advice on the tube. the are layers and layers of people screaming. advice on the tube. the are layers and layers of people screamingm was really traumatic. i arrived at the station moments after the blast and people were rushing out onto the streets. there was panic and some

people told me they felt lucky to be alive. the mayor called for calm while indicating the hideous individuals responsible. what has changed since the july the individuals responsible. what has changed since thejuly the 7th attacks? it is fantastic, any kind about bagram they'll come and join together. we will hear the person whojoins in to help together. we will hear the person who joins in to help the together. we will hear the person whojoins in to help the response. good evening, welcome to bbc london news and welcome to viewers joining us across news and welcome to viewers joining us across the uk on the bbc news channel. this was london's fourth terrorist attack in just six months. took place just terrorist attack in just six months. took placejust behind terrorist attack in just six months. took place just behind me at parsons green tube station during the rush hour this morning at 8:20 a:m..
