A suicide car bomber attacked a police station Saturday in northwest Pakistan, killing four people and wounding about two dozen, the Associated Press reported. The blast also toppled a mosque next to the police station in Karak in North West Frontier Province, said Ajmal Khan, a government official. Both police and civilians were among the wounded. The injured were transported to a nearby hospital where some were listed in critical condition. TV footage showed the charred skeleton of a vehicle and rescuers removing debris as they looked for survivors.
