Spanish police have discovered a car loaded with 100 kilos of explosives two weeks after the Basque separatist group ETA ended its ceasefire, media quoted police sources as saying Thursday, according to dpa. The parked car was found near Huelva in the southwest. The vehicle, which contained explosives and detonators, had fake Portuguese registration plates. Police sources said the car belonged to ETA. Police had warned of an imminent attack after the end of the nine-month ceasefire.
