A suicide car bomber detonated his explosives near a convoy of Afghan troops on Friday, killing one soldier and a child who was nearby. Another four soldiers and a child were also wounded in the attack in central Ghazni province, said provincial Gov. Faizullah Faizan. The latest attack comes a day after a suicide car bomb targeting a NATO convoy left three soldiers lightly wounded in eastern Khost province, and a bungled suicide attack hurt two civilians in southwestern Nimroz province. Last year, the Taliban launched more than 140 suicide missions _ the highest number since they were ousted from power by the U.S.-led invasion of 2001. Insurgency-related violence in 2007 left more than 6,500 people dead _ a record number, according to an Associated Press count of figures from Afghan and international officials.
