A car bomb exploded in Madrid today after a warning call from the armed Basque separatist group Eta, injuring one person, authorities said.

Anibal Altamirano said fellow commuters around him were too stunned to move when the first bomb blew apart a train.

Dismembered bodies entangled in the metal wreckage of train carriages. Amputated legs and arms scattered on station platforms. Thousands of people, many of them schoolchildren, fleeing in panic.
