almost 80 years. they've been reunited in california. hello everyone. dozens of people have been injured in this collision involving two subway trains in the south korean capital seoul. these are the latest images. the train was leaving the station when it was rammed from behind. many hurt are said to have jumped from the train. there are no serious reports of injuries. here is the latest. >> rescue operations at the subway station in the east of the south korean capital after the collision. witnesses said one train was leaving the station. another came in and rammed it from behind. the government emergency officials say many injuries were caused as passengers jumped onto the trains despite the announcement they should stay on the train and wait to be rescued. people forced the doors open to escape. seoul's subway system is heavily used and generally regarded as having a good safety record. why the two trains collided is not yet known. south korea is undergoing soul searching over transport stations after the ferry sunk with most school students on board. most in the ferry were told to stay in the vessel. while few in today's incident appears to be sainjured, the safety issues remains. >> what's your reflection on this incident? >> the incident seems to be relatively minor. it does raise questions about safety. if it's correct the oncoming train rammed straight into the back of the stalled train, that raises a question as to to why the safety mechanism failed. it should have a system that detects it's closing in on a stalled object. it is a heavily automated subway system. very mod earn, very efficient, moves millions around everyday across this vast area. as we were hearing there, it has a good safety record. koreans will rightly be asking themselves how it could fail. >> what about the issue of regulatory oversight particularly given the fingers pointed after the maritime agency after the disaster three weeks ago and now this? >> this is a question all south koreans are asking themselves and the government as well. the president park was saying herself the other day south korea has to tackle what she called evil malpractices. there's far too cozy links, easy connections between government officials. they are put in trade bodies and become lobbyists for big business at the same time responsible for safety. these questions are raised of course by the ferry disaster. there's a long record of really disastrous man-made tragedies going back 30 years. all come back a down to attitudes to safety and poor regulation. >> thanks for joining me. let's move on to east ukraine where events are moving quickly. government troops have launched a military operation against pro russian separatists around the city of sloviansk, a move by moscow is punitive. two are killed and another reportedly captured after two helicopters are shot down. officials in donetsk say pro russian separatists have taken control for the center of railroads in donetsk, the mining city, stopping all train services. let's go to sarah who joins me from donetsk. this is an ominous development as the railroads are seized by pro russian separatists. >> reporter: it is. of course it comes after a number of insulations here, key buildings, government building, prosecutor office here in donetsk taken over by pro russian groups. this is latest in that sense. it comes after the interior minister put out the word saying trains would be stopped. he said the railways would be closed down. difficult to know what to make of it. certainly another in a long line of key places now in the control of pro russian forces. >> sarah what about sloviansk, different parts of the city held by different factions including ukrainianss, pro russians and so on? >> reporter: not so much the city, no. the surroundings of the city. inside sloviansk itself, the situation is calm enough on the streets. we don't believe ukrainian troops have entered the city itself. pro russian forces still very much in control there as far as we understand. for the moment foreign journalist aren't allowed into sloviansk. they're stopped at check points on the way into town. difficult to know exactly what's happening on the ground. around sloviansk, there was a military operation launched by ukrainian troops in the early hours of this morning according to the interior minister. he says that nine check points were taken over by ukrainian troops, recaptured from pro russian forces. he says the city is now surrounded. we certainly can confirm there are ukrainians to the north of the city. the village to the west of the city has now controlled by ukrainian forces. to the south, on the road in, there's pro russian check points in place. i spoke to pro russian forces that said they were in control of several check points around sloviansk. in the fight this morning, we know confirmed two helicopters were shot down, two ukrainian helicopters. two ukrainian servicemen were killed. >> thanks sarah from that city in donetsk there in eastern ukraine. i'm joined by the bbc russian service. military service seizing major rail junctions is a critical part of any plan? >> it is. if ukraine would like the to move heavy machinery to sloviansk they'll have to use railway and troops. most the time troops are already there. what's happening around sloviansk is hugely important. russia would rather use it if they want to launch military operation there. >> there's also the possibility, dare i say, if pro russian separatists have seized railways, that could make it easier for russian forces to move to eastern ukraine quicker? >> definitely. we see the statements from moscow indicating russia is ready to use this. i've seen change of language where the word punitive operation which is russian, the second world war language used against germany forces. the same language is used now. that was somewhat forgotten in recent weeks and months, again up on the table. >> finally, what moscow is saying in public, language used. we've heard from the spokesman. >> the language used by the factions in the russian parliament is very tough. they're talking about a use of as much as possible pressure on ukrainian government. at the end of the day, the main thing is russian propaganda, the army moving into the peaceful town against peaceful people shooting civilians, creating hxgkçma >> a threshold has been crossed. >> absolutely. >> from the bbc russian service# thank you. now to nigeria in abuja. it's rocked by deadly i violence. an explosion has killed 19 and injured 60 more. that's according to the director of the country's emergency management about say. the car bomb targeted a bus station in the same place struck by a car bomb last month that killed 70 people. the i lammist group boko haram claimed responsibility. they are thought to be behind the 230 schoolgirls missing in the north of the country. the bbc has been to the seen of the blast. >> reporter: for theáuw&z cleanp after the bomb blast down here, the debris of this powerful explosion. if you come over this way, you can see the wreckage of some cars that were exploded during the blast. police officers here as well as the military and all sorts of people here really wondering why on earth this place is targeted again the second time in less than three weeks. if we move the camera over this side, that areañbuo# over there the bus station. that's where the bomb exploded killing more than 70 people. we don't know if this was boko haram. they said they carried out the attack on the 14th. perhaps this is a way, if it was them, of saying you can't secure your city whatever measures you put in place. there's anger as well as frustration and sorrow. this is coming on top of the terrible news of the more than 200 school children, girls being held by the militants. of course almost every week we hear of more attacks up in the northeast. this all happening at a worrying time. abuja, this city, is due to hold a world economic forum next week with heads of state coming here from all over the world. >> will ross will there at the scene of the bombing in abuja at the bus station. to sudan that faces ethnic, tribal killings. secretary of state john kerry just arrived. he's calling for a peace treaty that forced thousands to flee their homes. bbc is there. >> reporter: once vibrant and busy, this is now a ghost town left deserted. frustrated by months of endless fighting. senior officials are here to witness first hand the damage. >> this used to be a thriving mosque area. as we look around, just over here this was a market. with thousands of thousands around. i know this place well but not like this. >> reporter: those that survived bloody killings in the town have been in refuge. 20,000 are sheltering here. it's a rainy season. harsh conditions are getting worse, almost unbearable. now there are fears of an outbreak of diseases. >> translator: water is everywhere. we are suffering from it draining. i'm scared my two children might get sick. >> reporter: families with only what they have left brave the scorching sun to find a way out but don't find much hope. >> everyday people like the this come to the airport walking for hours wanting to leave. if they don't get a flight out of here, they walk all the way back home. >> reporter: a few hundred kilometers north, this is the town which is the bread basket of the country. farmers have fled their fields. it's a shadow of what it was. a chilling prospect for the future of a country that recently looked so bright. bbc news. aaron is here joining me with the business news at low volume. >> your volume has gone up i know. >> what's happening in the drug's world, pharmaceuticals, massive turnovers. >> the deal potentially -- i think shareholders like it to happen indeed. let me explain. hello. rejected, that's whats atrazeneca rejected the bid. the $84 a share offer is coming back to this, undervalues the country. this coming from the board of the country. shareholders are fully backing the bid. so today's rejection is unlikely. it's going to continue this story. not the end at the moment. the board don't like the amount. they say it's too low. shareholders say not bad. how about this one?

>> reporter: not so much the city, no. the surroundings of the city. inside sloviansk itself, the situation is calm enough on the streets any way. we don't believe ukrainian troops have entered the sloviansk city itself. pro russian forces still very much in control there farce we understand. i say as far as we understand because at the moment foreign journalist aren't allowed into the check point. they're stopped on the way into town. difficult to know what's exactly happening on the ground. there was a military operation launched by ukraine trian troop early this morning according to the security minister. he said nine check points were taken over. he says that the city of sloviansk is surrounded. we can confirm there are ukrainians north of the city. we believe another city to the west is controlled by ukrainian forces. to the south, on the road in, there are pro russian check points there. they were still in control of check points around sloviansk. in the fight this morning we know two ukrainian helicopter were shot down and two servicemen were killed. >> it's reported by the ukrainian interior ministry pro russian separatists have left the prosecutor's office and television center in another of the big cities in the east. more on that as we get it. i'm joined by our diplomatic defense. seizing a raille head junction like that, what's your assessment of what this means? >> more infrastructure falling into the hands of pro russian separatists. clear are yly there's reports o power. that means signals and so on are not working. it is yet one more element of the region falling into chaos. clearly i think the great fear now with the temperature rising, with this operation launched by the kiev government is if that operation is in any sense successful. it could potentially give russians pretest to take military action of their own. at the moment, events on the ground are confused. it's very unclear with the losses of helicopters and so on. doesn't look as though things are going that well for the kiev government forces. still, a huge raising of temperature now over the last few hours. >> but in so many previous examples like what's happening in eastern ukraine, the excuse has been to stabilize a problem and make sure it doesn't get worse. >> the russians have been clear from the out set. they have set out the narrative there. their story, set of excuses if you want to call it that, or reasons to intervene, all along has been to defend the russian speaking population of eastern ukraine. clearly the rhetoric comes from moscow, talks about a punitive attack by the kiev authorities. kiev authorities talking about an antiterrorist in their concerns. if kiev authorities really did begin to get the upper hand in this city, that's often clear that's the case, i think the pressure would be on the russians to decide what they were going to do. >> finally, when you listen to john kerry a few days ago being volcanic in condemnation of russia making clear there are connections between pro russian separatists in eastern ukraine and russians giving orders from moscow essentially. what does that mean when you put together what you just said with the overarching landscape emerging? >> i think what you have is a clear effort by the russian in new russia as they call it. areas where there are russian speakers to see moscow's views prevailing. i think it's a dangerous situation not just ukraine but georgia and other places in the region. that's something western governments are going to have to con detend in years to come. >> thank you jonathan. abuja has been rocked by violent. a bomb has killed two and injured 16 others. the car bomb targeted the bus station in the same place struck by a car bomb last month that killed at least 70 people. the militant group boko haram claimed responsibility. they're thought to be behind the 230 girls abducted from a school in the north of the country. will ross has been to the scene of the latest blast at the bus station. >> reporter: for the cleaning up after the bomb blast down here if in the city, the debris of this powerful explosion. if you come this way, you can see the wreckage of some cars exploded during the blast. police officers here as well as the military. all sorts of people here wondering why on earth this place is targeted again, the second time in less than three weeks. if we move the camera over this side, that area over there is the bus station. that's where the bomb exploded on the 14th killing more than 70 people. we don't know for sure this was boko haram. they said they carried out the attack on the 14th. perhaps if it was them, this was a way for them to say you can't secure your city. there's some anger, frustration and sorrow because this is coming on top of the terrible news of more than 200 school children still being held. girls are held in the northeast of the country by suspected militants. of course almost every week we're hearing more attacks in the northeast. this all happening at a worrying time. abuja, this city is due to hold a huge event. the world economic forum next week with heads of state coming here from all over the world. >> well there the view from the bus station. let's go to holly gordon, president of girl rising, global campaign for girl education. this features the stories of schoolgirls. you were in nigeria last october. 230 missing. what are your predictions? >> well it's obviously a great tragedy that citizenship of nigeria has to deal with things like this bus explosion. for girls in nigeria the opportunity to have education for any child in the world, the opportunity?vfñ3u a[7][?[zncvl[wãfuture. so i'm very hopeful about the future. i'm always hopeful. suddenly this kidnapping is a great, great tragedy. >> we're seeing protestors at the moment holly, who have been protesting the families in particular. what is your thoughts on the level of progress and what boko haram is trying to do? >> boko haram has made girl education their work. we have a different opinion around the world. we have seen what happened. often militants target girls as a way to keep control. and it's just not okay. >> now there is going to be in the next few days a meeting of the world economic forum committed to improving the state of the world. they're going to abuja where there have been two big attacks and 230 girls missing in the jungle in the east. you're saying the world has to engage and not lead it to nigerian leadership? >> absolutely. the world cannot stand by while innocent girls are held hostage. these are girls who went to school to learn. that's it. they it wouldn't school to get an education. we must not stand by while they are held. >> but what kind of leverage do you believe the outside world has? as you know, nigh -- nigeria has significant power. the government feels it has significant power as well in the country. >> i believe in power of social movement and social action. i believe the marches across nigeria and around the world with after dress the challenges of safety in nigeria whether a bus bombing or children kidnapped. this is a place investment of diplomacy is as important as investment of economics. >> thanks for joining me holly. >> thank you. dozens of people are injured in a collision involving two subway trains in seoul. reports say the train was leaving the station in the east of seoul when it was rammed from behind. many of those hurt were said to have jumped from the damaged train. there are no reports of serious injuries.kv?

>> this is a question that all south koreans are asking themselves and also the government as well. president park herself was saying the other day that south korea has to tackle what she called an evil malpractice. there's recognition in south korea that there's cozy links between regulators, government and big business. easy connections between government officials are often put into trade bodies and they become lobbyists for big business at the same time responsible for safety. these questions have been raised of course by the ferry disaster. there's a long record of really disastrous man made tragedies in south korea going back 20 or 30 years. all of them have come down to the same question about cavalier attitudes of safety and poor regulation. stay with me here on bbc world news with me nik gowing. still to come. meals developed by school children for space. what will they come up with?
