Afghanistan ? A suspected suicide bomber detonated explosives in a car near a U.S. military convoy Monday in the southern Afghan city of Kandahar, killing himself and wounding an American soldier and two passers-by, officials said.

The convoy was attacked as it drove through the city, a former Taliban stronghold and the site of a string of recent suicide bombings.

One U.S. soldier was only slightly hurt, said Sgt. J.C. Woodring, a U.S. military spokesman in the capital, Kabul.

Kandahar Gov. Asadullah Khalid identified the wounded passers-by as a woman and a child. Both were taken to a local hospital.
