Fighting between two rival factions has killed about 30 people in Shindand district of the western Herat province of Afghanistan, the provincial police said on Monday.
The conflict broke out Sunday after some militants loyal to local commander, Arbab Basir, ambushed a car carrying another high ranking official Amanullah Khan.
The ambush occurred in Shindand district, about 120 km south of the provincial capital Heart.
About 30 people from both sides including Khan and his son were killed in the ambush and many others were injured, the official said.
Meanwhile, a spokesman of the NATO forces in Herat confirmed the fierce fighting and the deaths.
The spokesperson said some NATO soldiers have been despatched to the district to keep security, but he declined to tell the exact number.
Khan, an ethnic Pashtun commander, who had hundreds of militias under him, frequently clashed with his Tajik rivals led by former Herat province governor Ismail Khan in the previous years.
