On and on

Another disaster:

More than 600 people were killed and hundreds injured this morning when rumors of a suicide bomber led to a stampede in a vast procession of Shiite pilgrims as they crossed a bridge on their way to a shrine in northern Baghdad.

Most of the dead were crushed or suffocated, witnesses said, but many also fell or jumped into the Tigris River after the panicking crowd broke through the bridge's railings.
