An explosion struck a busy road during rush hour traffic in the Afghan capital of Kabul on Wednesday, police and witnesses said.
The blast, suspected of being set off by a suicide bomber, occurred just before 5 p.m. on a major road near a university and an old parliament building, said Najib Danish, a spokesman for the Interior Ministry.
The target appeared to be a bus carrying employees of the Ministry of Mining and Petroleum, said Sediq Seqqi, a spokesman for the Interior Ministry.
Among the wounded were three men and one woman, officials said.
Photographs from the scene showed a small bus with its windows shattered by the blast.
