A suicide attacker dressed as a woman detonated bombs strapped to his body at a checkpoint on Afghanistan's border with Pakistan Tuesday, killing a policewoman, an official said. The man, dressed in an all-covering burka that most Afghan woman wear when in public, blew himself up in a room at the Torkham border post used for searching women travellers, a provincial government spokesman said. "The burka-clad suicide attacker detonated his explosives at the search room for women and killed one border policewoman," Nangarhar province spokesman Ahmad Zia Abdulzai told a foreign news agency. Three male policemen and six civilians were injured, he said. The wounded were rushed to hospitals across the border in Pakistan and there was no immediate word on their condition, Abdulzai said.
