terrible fire fights. a similar one in belgium was the largest raid in the history of belgium since the second world war. this one in paris, you can probably make the same comparison. there s never been anything like it. i think these things are going to become all too familiar in europe over the next two or three years. isis is ratcheting up their ring leader who orchestrated this. and they have safe haven and are trying to recruit fresh recruits and sending them back. the reason they are doing such quick training is people can book a two or three-week holiday, slip into syria, come back and the european intelligence services aren t going to suspect they got all the way into syria because it s so quick. paul cruickshank, thank you so much.
