Four people were killed and two others wounded after a roadside bomb hit a vehicle in the southern Kandahar province Friday night, a local official said on Saturday.

"A mine planted by militants struck a car in Dand district Friday evening, leaving four persons including three security personnel and a civilian, dead," spokesman for Kandahar provincial government Samim Khapalwak told reporters.

Two other civilians sustained injuries in the blast, he added.

Taliban militants, who are fighting the government largely with suicide and roadside bombings, have not yet claimed responsibility for the attack.
