A roadside bomb organized by militants claimed the lives of two persons including a district chief and injured two others in Afghanistan's northern Kunduz province, provincial police chief Mohammad Raza Yaqubi said Sunday. "The incident occurred in Qalai Zal district on Saturday evening. As a result governor of Qalai Zal district Mohammad Nazir and his driver were killed on the spot," Yaqubi told Xinhua. His son and bodyguard were injured in the blast, he said. Kunduz has been the scene of increasing militancy since early this year. A similar roadside bomb organized by Taliban militants injured two NATO soldiers in the neighboring Chardara district on Saturday.
