No serious injuries are reported following a car bomb blast in northern Spain.
The explosion occurred close to a Guardia Civil police station in Calahorra, a town in the Rioja region, after a warning from the Basque separatist group ETA.
The bomb warning disrupted a Holy Week procession and some people, including a police officer received minor injuries.
ETA issued a warning stating the location of the bomb and the make, model and colour of the car.
The police station and surrounding area had been cleared and cordoned off before the explosion.
