Read an old issue of Newsweek about the suicide bombers in Israel during my invigilation break, and found out that: A bomb-blast victim can appear unscathed with nary a scratch on the outside, but still have massive internal injuries, for example, the lungs have exploded *grimace* or the liver is bleeding (in any case, death is near). These injuries are caused by shockwaves from the blast, which are even worse if the blast took place in a confined area, e.g a bus with the windows shut. A bomber also applied rat poison (an anti-coagulant) inside his bomb, such that victims with puncture wounds from the flying nuts and bolts will bleed non-stop.
