Simultaneous explosions killed 173 people and injured about 600 on packed trains in Madrid on Thursday in pre-election attacks in what could be the bloodiest day in three decades of violent Basque separatism.

There was no immediate claim of responsibility for the blasts which ripped open rush-hour trains like tuna cans and splattered blood everywhere at one of the three stations hit just ahead of a Spanish national election on Sunday.

Les doy mi pésame a todos los familiares y amigos de las víctimas.
