Rumour of a suicide bomber among Shia pilgrims causes a panic and a stampede on a bridge in Baghdad that kills 841 people according to some reports, at least 695 and possibly 1000 according to others. About as many people as the war has killed this month. And of course, the atmosphere of fear that the war and the suicide bombings have created, caused the death of these people, and they too are casualties of the war.
