Sad Sad Sad Sad day





MADRID, Spain (CNN) -- At least 50 people have been wounded and several killed after a series of explosions ripped through Madrid's southern railway system at the height of morning rush hour.

At least four explosions were reported with one of the blasts hitting a crowded commuter train car at the capital's main Atocha train station, according to Spanish media.



SER radio reported many casualties after one of the explosions hit the train as it arrived at the station from the eastern Madrid suburb of Alcala de Henares.

The first blast struck a vacant train car and soon after a second explosion hit the crowded commuter train, SER reported.

Police and emergency services were evacuating the station which serves both city and long-distance trains.

Witnesses at two other stations -- Santa Eugenia and El Pozo -- reported other explosions.

Spanish media, quoting witnesses, were quick to link the blasts to Basque terrorist group, ETA, but no one has yet claimed responsibility.

A planned Christmas Eve attack on Spain's train system by ETA was foiled last year.

The blasts hit three days before a Spanish election that has been focusing on the ruling parties tough line against ETA.

Listed as a terrorist organization by the European Union and the United States, ETA has killed 838 people since 1968 as it presses its demands for an independent state.
