MADRID, March 11 — In the bloodiest terrorist attack on a European target, 10 bombs exploded during this morning's rush hour in three commuter train stations here. The Interior Ministry said more than 190 people were killed and more than 1,200 wounded.
Three other bombs were discovered and detonated by the police in the highly coordinated explosions, which went off within a 10-minute period.
As the country struggled to absorb the carnage just three days before general elections, Prime Minister José María Aznar appeared on television and called the attacks "mass murder." He vowed that Spain would never negotiate with "these assassins."
Mr. Aznar added, "March 11 now has it place in the history of infamy."
