so this youth group held this event to celebrate kobani, to talk about rebuilding kobani, held up the banner, posed for photos, and in the middle of that, as these photos were taken, one of the students in the middle of that crowd set off a suicide vest and 32 of those kids were killed. it was apparently a turkish student, who had crossed over into syria and joined up with isis and crossed back over the border. they sent him back home to turkey to infiltrate that youth group and he ended up killing dozens of those kids all at once. that's isis picking a soft target to be their revenge for losing the city of kobani. isis very much likes soft targets. today's bombing in istanbul's airport, this huge cosmopolitan busy airport, the third busiest airport after london's heathrow and charles de gaulle in paris. suicide bombers detonating their vests and shot by police inside the airport. every attack is new, but this feels like a new angle rerun of brussels. they had bombs that were studded with nails. they hit a departure hall, followed by a second attack in a brussels metro station. and br

kobani was not the biggest population center.was not seen as hugely strategically important but it was right on the border between syria and tu a

in kobani, one of the ice i defectors they went like lemmings off the cliff and the ones that were theted, die hard death cultistists, right? other battles where isis was being sent into sudden death where the coalition could spot them from the sky and the kurdish forces on the ground would shoot at them and essentially picking them off one by one and a lot of them ran away and deserted and they didn't want to play this game anymore. the kamikaze warriors as clarissa was saying. on the battlefield they'll shoot you up when they run out of am nation and they'll actually run up to the enemy and hug him and grab him so that they take them out with him. there was a remarkable story in the wall street journal about how they disappeared from fallujah. they essentially left their comrades to die in these readouts in the hospital in fallujah. there was an isis contingent and they said what about the shab abover there, we'll see them in the afterlife. don't worry about them. this is one of the reasons why they're extending manpower and resources so recklessly. >> we have to leave it there. mich

borders syria and the fact that isis was on turkey's doorstep when it was controlling the town of kobani which was on the border and fleshed out by the pkk, and there have been long standing complaints about the security on that border and the ease with which jihadi fighters pass through turkey into syria and the ease that isis fighters have been able to get into turkey. what do we know about the border situation there right now? >> we know border security has been tightened up by the turks with regard to isis over the last year. however, you have to look at this in reverse. isis has managed to bring in between 30 and 50,000 people to join their caliphate over the last few years. most notably the last two years, the overwhelming majority of those people came in through turkey. they still have networks which are covert, which are underground, and even if the turks place strict security controls, they have the ability to get back and forth with manpower, money, and equipment. you have to remember, there's a turkish isis organization. they have turkish language, issues of dabiq magazine, wh

before they lost kobani, in september 2014, abu muhammad al adnani and the famous one, pick up the rock and smash the kof ar's head and if you're a muslim, you live in the land of disbelief to carry out these attacks even if you're inspired by the ideology. since it's begun to shrink, it is true that trained up operatives people that have been to raqqah and received the bomb training. remember, you have to volunteer to be a suicide bomber in isis. one of the security officials told me that after he defected. in this, since the loss of this territory they have dispatched these agents abroad to carry out these operations. if those guys and if looks to me, anderson, that those guys that conducted this attack at the airport, had some kind of combat training and it was not ultra professional, but it was something. if they were trained in syria i would be very surprised if in the next days or weeks you didn't see a propaganda video on the battlefield holding a knife to the hostage's head and that's exactly what the paris attackers happened after their attack. >> juliette, in terms of threats
