BILBAO — A bomb exploded next to the headquarters of Spain's ruling Socialist Party in Bilbao. The blast happened at about 1am on Friday.The device, which police said might have been made from a canister of camping gas or a bottle of inflammable liquid, caused no injuries and damaged only the building's window blinds.
Police said armed Basque separatists ETA or young supporters of the outlawed group who keep up a regular campaign of street violence might have been responsible for the blast. Police suspect ETA was behind a bomb that exploded early on Thursday in the Basque seaside town of Zarautz, causing slight damage but no injuries.
The Basque terrorist organisation has killed nearly 850 people since 1968 in its campaign for an independent Basque state in northern Spain and southwestern France
