Four explosions struck near a power station in Spain's northern Basque country today after a warning call in the name of Basque separatist group ETA, police said.

State radio said there were no injuries.
A caller to a Basque newspaper had warned earlier that four bombs would explode near the power station at Amorebieta, police said.
Earlier, a Spanish policeman was injured and a bomb-sniffing dog was killed when a small bomb detonated outside the Italian Cultural Institute in Barcelona.
Staff at the institute called police after they arrived for work this morning and found a suspicious object - a metal coffee pot with wires sticking out of it - on the steps leading into the building.
The explosion occurred while police bomb-disposal experts with a bomb-sniffing dog on a long leash were examining the device, he said. Spanish National Radio said the policeman was only slightly injured.
