Madrid bombings: One year on.

March 11, 2005 marked a year since the devastating terrorist attacks in Madrid, in which a string of powerful bombs were detonated on packed commuter trains. The blasts killed 191 people. More than 1,500 were injured, and survivors are still struggling to rebuild their lives.

A total of 22 suspects are being held in jail, and another 52 detainees have been released. No formal indictments have been issued and observers say a trial is probably months away. The bombings —the worst attack against a Western country since the September 11 strikes in the U.S. — were dubbed "Spain's 9/11."
