Scores Killed in Madrid Train Explosions
Ten powerful explosions rocked three Madrid train stations Thursday just days before Spain's general elections, killing at least 173 rush-hour commuters and injuring more than 600 others.
Spain blamed the Basque separatist group ETA for the worst terror attack in its history, but a senior U.S. intelligence source told NBC News that that's still not conclusive and that the CIA is looking for any connection to the al-Qaida terrorist network.
