A suicide bomber rammed an explosives-laden car into a minibus carrying Afghan soldiers in a crowded market south of Kabul on Wednesday, killing at least 13 people and wounding 20, officials said. The Taliban claimed responsibility. The third suicide blast in the city in the last eight days was in line with the militants' strategy of staging spectacular attacks on Western-trained security forces, but civilians usually pay the highest price for the tactics. The bomber's Toyota Corolla struck a minibus full of troops at a bustling market in the Chihulsutoon area, said Aziz Ahmad, an Afghan army officer at the scene. Officials said six soldiers and seven civilians, including four children, were killed, while seven other soldiers and 13 civilians were wounded.
