At least 131 dead in near simultaneous bombings of three different trains during the morning commute. Spanish officials are blaming Basque separatist group ETA.
Three separate trains were hit by near-simultaneous explosions before 8 a.m. (2 a.m. ET) along the southern part of Madrid's train network at Santa Eugenia, El Pozo and Atocha stations, officials said.
The most deadly blast happened on a train entering Madrid's main Atocha station, according to Interior Minister Angel Acebes.
The attack comes ahead of Sunday's general election in which Spain's conservative ruling Popular Party -- which has taken a hard-line stance against ETA -- is currently leading in the polls.
