A car bomb planted by suspected members of the militant Basque separatist group 'ETA' injured 46 people overnight in the northern Spanish city of Burgos, hospital sources said Wednesday. The car had been parked behind police barracks where families of police officers live, according to a report of the German News Agency "DPA". Thirty-eight of the injured were taken to hospital, but none of them were reported to be in a serious condition. The victims included police officers, their wives and children. Most of them had bruises or cuts from shards of glass. The bomb caused considerable damage to the 14-storey barracks, ripping a part of its facade open and causing a side wall to collapse. It also damaged surrounding buildings, some of the residents of which were evacuated. The explosion left a gaping hole in the ground. Officials attributed the attack to ETA, which marks the 50th anniversary of its formation on Friday.
