Authorities in northwestern Pakistan say a road-side bomb has exploded near a vehicle and wounded at least three people in the South Waziristan tribal district.
Authorities in the village of Shakai say a local militant commander was in the vehicle with at least two others when the bomb went off on Sunday.
Officials say it is not clear who planted the bomb or if it was intended for the militants.
Earlier this month, the Pakistani government reached a peace deal with pro-Taleban militants in neighboring North Waziristan. Pakistan's military ended its crackdown in the region and the militants were to stop harboring foreign al-Qaida-linked fighters.
