A district governor and three others were killed in a militant attack in northern Afghanistan, while seven police personnel were killed in a roadside blast in country's southern region, officials said on Wednesday.
Mohammad Muhsin, district governor for Dehna Ghori of northern Baghlan province, his son and two other government officials were killed when their vehicle was ambushed by Taliban militants in the district on Wednesday morning, Jawid Basharat, spokesman for the provincial police chief said.
He said the attackers fled the area before police reinforcement arrived at the scene.
The northern region is relatively more peaceful than the country's southern and eastern regions, where Taliban militants are most active. But insurgents appeared to have penetrated new areas in the northern provinces. Militants briefly overran a district in the same province last week.
In the southern province of Ghazni, seven policemen were killed and another was wounded when their vehicle was blown up by a roadside bomb in Andar Wednesday, Khialbaz Sherzoy, the provincial police chief, said.
Taliban spokesman Zabiullah Mujahid claimed responsibility for both of Wednesday's attacks.
The militants launched a countrywide offensive last week, vowing to increase their attacks on Afghan government officials and around 70,000 international troops stationed in Afghanistan.
