Bombs exploded Friday in five pumping stations of Madrid, leaving no victims, but causing material damage, said the Spanish Interior Ministry.

The attacks occurred at 18:30 hours, local time and responsibility was claimed by separatist organization Basque Homeland and Freedom (ETA).

These service stations had been evacuated beforehand, after an anonymous phone call on behalf of ETA, warned Basque daily Gara, on the imminent explosions.
