Five people were injured in a blast that rocked Faizabad district in Afghanistan's northern Jawzjan province on Tuesday, a police official Kamaludin Yawar said.

"Five innocent children were passing a street in Faizabad district this morning when a mine planted by militants went off and injured the innocent children," Yawar told Xinhua.

Without providing more details, the official said that an investigation was underway.

Taliban militants who are active in the area and are largely relying on the suicide and roadside bombings haven't commented on the incident.
