No one has claimed responsibility for the kidnapping of an American aid worker in southern Afghanistan, but intelligence agents are working to find her captors, police said. Taliban spokesman Zabiullah Mujahid reiterated Monday that he could neither confirm nor deny that Taliban gunmen had taken the American woman and her driver. Gunmen seized Cyd Mizell and Abdul Hadi on Saturday in a residential neighborhood of the southern city of Kandahar. On Monday, the police chief of Kandahar province, Sayed Agha Saqib, said police had not turned up any new information about the kidnapping. "All of our security forces and intelligence agents are trying to find them," he said.
