SPANIARDS lit candles, laid flowers and observed a long silence yesterday to mark the first anniversary of the country's worst terror attack, when 10 bombs ripped through commuter trains, killing 191 and wounding more than 1,500.

Spanish Prime Minister Jose Maria Aznar pledged today to find those responsible for the worst terrorist attack in Spanish history as the nation mourned the 198 who died in the string of train bombings.

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.
