2004 train bombings in Spain

Rescue workers cover up bodies alongside a bomb-damaged passenger train, following a number of explosions in Madrid, Spain, March 11, 2004, killing more rush-hour commuters and wounding more than 500 in Spain's worst terrorist attack ever. An Al-Qaida-linked group that claimed responsibility for the Madrid train bombings warned European nations that they have only two weeks to withdraw troops from Iraq or face the consequences, a pan-Arab newspaper reported Friday, July 2, 2004.  <span class=meta>(AP Photo/Paul White)</span>
