A series of terrorist bombings in the Madrid commuter train system killed at least 190 and injured over 1,240 during this morning’s rush hour. Thirteen bombs were found around the Spanish capital, 10 of which exploded in or near trains.

Spanish officials initially blamed Basque separatist group ETA, but that group has denied responsibility.

Police have found a van near the scene of some of the bombings which contained detonators and Arabic materials, leaving some to conclude that these acts were carried out by Al Qaeda or a supporting group.
