shrine was just like shredded into pieces. >> unfortunately, marco, we're having a few problems hearing you right now. we're trying to get that worked out. because marco was on the scene very, very quickly, and what he has described is bodies shredded by the power of this blast. he treated as many of them as he could. and he did say it was one of the worst scenes he has seen. we'll try to get marco back. maybe we can continue talking with him. in the meantime, police say they believe it was a pipe-bomb. i asked bob behr about that a short time ago. >> i doubt that it's a pipe-bomb. it could have been, but with that many deaths, it's usually a sophisticated pipe-bomb. a couple other things is they attacked a tourist site.
