>> i'm just going to hop on the back of what ayman was talking about and jump in before malcolm nance. i've done some digging here. this is from "inspire" magazine. this is from an issue in 2010, and they talk about the inability to get your hands on certain weapons, and they write, quote, you can still carry out attacks by burning down forests and buildings or by running over them with your cars and trucks. it continues. if you can kill a disbelieving american or european, especially the spiteful and filthy french or an sprawlian or a canadian or any other disbelievers from the disbelievers waging war. what i would submit is most of the middle east is watching horrendous images come in from syria, from libya. barrel bombings every day. and this is a broader war on peaceful nations. this is a war against nations that are not in this state of constant war. i spend the majority of my day looking through isis propaganda videos, looking through horrible images of bombings in syria, in libya. and if you live in the middle east and you turn on al jazeera as your main news source, that is wh

you know, your discussion there with ayman and the reporting just before, that he was going to -- was trying to dial a cell phone, trying to dial a cell phone could be -- it's very common in the middle east, and around the world for terrorists to use a cell phone as a trigger. so they plant a receiver, a cell phone inside the bomb, they rig it up to an electric detonator and when they dial the phone t detonates the device. it could be in the back of the truck as we're surmising, and that's a very good guess, we should be suspicious of that. the bomb squad has to take it out, but it also could be another location. also, he could be calling, you know, trying to call someone to claim credit, 911 if you will. we don't know the answer to those things. he had the lights out. he slowed down. the motorcycle cop was next to him. it's like a whale and there are a couple dolphins. they're not stopping the whale. it's too big and it's going, and he had this open area to just wind through the pedestrians. the way to stop that truck is never let the truck get there in the first place. you have all

joining nee now, nbc news foreign correspondent ayman mow mohyeldin, let's put this in the context of the last month. just in the last month, orlando, 50 dead, 49 killed, including the shooter who pledged allegiance to isis. the attack on the istanbul airport, which appears to have been also the work of isis, although no formal credit, though we believe it was them. dozens dead there. the dhaka attack, just in the same week as that, and now this in nice. >> and don't forget about iraq. >> 250 -- >> bigger than all of these. and it's not to say that one is bigger than the other in terms of the magnitude of the loss, but what it demonstrates is the capability of whoever is behind all of these attacks. i don't mean behind it from an operational point of view, but operationally in the sense that there's an ability to inspire these types of attacks. and you know, we're not -- we're still in the very early stages, not sure who is behind this in terms of an organization, but the deliberate attack, and when you start putting it on a -- analyzing it through a matrix of possibilities, the symbo

. >> ayman, we are ready to say this is now over. very dramatic developments in just the past two hours. at about 10:00 p.m. local eastern time, our time, that raid began on the restaurant with commandos entering that restaurant. there was a hail and exchange of gunfire. we're talking about the rapid action battalion that's basically like an s.w.a.t. team equivalent in bangladesh. that raid went on for ten to 20 minutes. there was a series of explosions. i want to go through mamuna. we've been speaking to her. give us an update of what you've witnessed, what you saw and heard over the course of this operation as it unfolded from your vantage point. hello, can you hear us? all right. it seems that we have lost mamuna. >> hello? >> hello, are you with us? okay. we're going to try to re-establish that connection if we can. but with us here in studio, we have with us malcolm nance. malcolm, we've been talking about the significance of this operation. some very important pieces of the muzzle that we've learned. some of it, we're not able
