but so far, there has been no claim of responsibility. this security camera video ppears to show bystanders sprinting for cover. just moments before an explosion tore through the airport. and these shaky images seem to capture one of the armed gunmen being shot. and then writhing on the ground before also blowing himself up. the sound of another explosion rocked those waiting outside the terminal building. the aftermath was a scene of horror. in one of the world's busiest airports. with lifeless bodies littering the ground, and emergency workers searching for survivors, amidst the destruction. many people who witnessed the attack looked to be in shock. like adam keely, a tourist from boston. >> the bombs went off. and people started running the other way. there was more shooting. c

and -- and, after that, i think there was another bomb. >> reporter: this is the latest in a spate of deadly suicide bombings in turkey over the last year. the turkish authorities have blamed isis for some of them. including two that targeted foreign tourists. but unlike similar attacks in europe, isis has never claimed responsibility. other bombings were carried out by kurdish separatists. members of an ethnic minority who are locked in a long-running conflict with the turkish state. relatives of the injured waited for news this morning. their loved ones were caught up in an active -- act of terror in a country that used to be an island of stability in the middle east but now is descending deeper into chaos and violence. this attack has saddened people in turkey, but given the deteriorating security situation, very few here will be shocked. >> the terror attack in turkey

we are still learning all the facts. but we know this is part of our broader shared fight against terrorist networks. and we will continue to work closely with turkey to root them out. meanwhile, we are going to do what is necessary to protect our people. i'm confident we can and we will, defeat those who offer death and destruction. we will always remember, even as there are those who are trying to divide us that we are stronger when weep co come toge and work toward a better world togethe together. >> reporter: this has at signature of an isis attack but they're waiting on further intelligence. just a day before the istanbul bombing, u.s. intelligence indicated an attack on foreign tourists particularly americans was imminent. that led the state department to reissue a public warning and ordered families of american

parts of the country. so far this morning it does not look like american citizens are among the casualties. for president obama, though, this is the third time in the past year that a major summit is overshadowed by terrorism. here in ottawa, mexico, canada, and president obama representing the u.s. were all supposed to sit down and tackle tough climate change issues including a pledge to switch to renewable clean energy and tackle immigration issues. and all of the talk of the 2016 campaign and building walls, cutting off some of the passage with mexico has been very controversial. but right now security as you say is at the top of the agenda as well. this attack in turkey could be a game changer. turkey is a u.s. ally within nato. that means they can compel the u.s. and europe to take action. this sets the stage for some intense talks next week when president obama sits d

>> reporter: there are gun lovers and then there are marines. that may look like a rifle to you. to a marine infantryman, it is the difference between success and failure, life and death. >> that weapon is basically, that is your tool to keep yourself and friend alive. and do the job at hand. >> marines refer to their rifle >> when you push forward and you are actually in iraq and afghanistan or wherever the marine corps might send you the weapon never leaves your side. >> reporter: he is holding an m-4, newest rifle issued to marines. his battle buddy, corporal shamar methany carrying the m 16. >> 26 inch barrel. his is 14 and a half. >> reporter: the m-4 has a shorter range but 2 pound lighter. >> 2 pound is a lot when you are counting everything you are trying to put on,

marine. >> reporter: a shorter barrel may not mean much out here on the firing range. but could mean everything in urban combat. >> if you are coming around a corner into the hallway. inches can mean a big difference when it's showing that you are coming or not. >> reporter: all the rifles are becoming smaller and lighter. colonel roger turner the man in charge of developing new weapons for the marines says the addition of a telescopic sight is the biggest change. most people when they think telescopic sight they think of a sniper rifle. >> right. >> reporter: every rifle has it. >> every rifle, yes. >> so what would be considered a, a -- sniper-like effect can be achieved by this, by every single marine. >> reporter: the real snipers are creeping through the woods carrying a very different kind of weapon designed to pick off the enemy at long-ng

sergeant jacob ruiz is wearing. his rifle is custom tailored. >> don't imagine there is anybody that has a closer relationship with his weapon than a sniper. >> snipers fire far more round with a lot more responsibility and understanding of what that round is doing than any other form of infantry i would say. as with the infantry rifles, marines are switching to a smaller lighter sniper rifle. >> this one is on the way out. >> essentially. >> you going to miss it? >> yeah, yeah, all i have known since i came to this. >> the sergeant can console himself with the fact that uh new rifle is lighter. >> pound equal pain. so, the less ounces you got, the less pane you are going to have. >> reporter: each rifle in a marine fire team has a different purpose. the snipers are usually first to fire, trying to pick off high-value targets liken me machine guns. giving the rest of the fire team a chance to move across open ground. first to come up is machine gunner ryan moore to lay done a base of fire.

the first guy forward. >> absolutely. >> that can be risky. >> when i was in afghanistan, it seemed the machine gunner had a target painted on the flak jacket for the enemy to shoot at. >> reporter: that drum contains 200 round which he fires in two to three second bursts. any longer and the guns recoil will make his shots go wild. >> in my opinion for the most part, machine guns will actually change or paint the actual outcome of the battle space. i'm going to instill confidence in my squad and ability to move forward. then put that fear in the enemy where they don't want to fight. >> reporter: these marines could spend all day telling you intricacies and idiosyncracies of their weapons. here is the one thing you need to know about the marine and his rifle. >> a personal thing. something you take ownership of. if there is something wrong with it, something you didn't do properly, not the weapon itself. you fix it. make it better. get back in the fight. >> reporter: the weapon is only as good as the marine? bs

weapon will do what it is designed to do. marines are trained to make it
