A small device exploded at the offices of a property company in the Spanish city of Bilbao on Saturday and police said it was likely the work of Basque separatist guerrilla ETA. No one was injured in the blast that followed two small bombs earlier this week by the armed separatist group. "In principle, we are considering this as an ETA attack, similar to the ones earlier this week," a Basque police spokesman said. The device, containing about 1 kg of explosives, went off at around 1700 (1500 GMT) in a central street in Bilbao in the offices of a property company, police said. ETA, branded a terrorist organisation by the European Union and the United States, has killed more than 800 people since 1968 in its campaign for an independent Basque state. French police seized two more ETA arms dumps earlier this week and found 25 kilos of dynamite and 30 detonators, along with numerous guns and anti-tank rockets. Police are still following up leads following the arrest on October 3 in southern France of a couple suspected of being ETA's top leaders, considered a major blow against the guerrillas.
