An Afghan official says at least six civilians were shot and killed by gunmen in western Ghor province.

Iqbal Nezami, spokesman for the provincial police chief, said that four other civilians were wounded after their vehicle was attacked near Faroz Koh, the provincial capital, on Tuesday morning.

The victims were all ethnic Hazaras, a Shiite minority in Afghanistan that is frequently targeted by Sunni extremists in different parts of the country.

Nezami says the Hazaras were on traveling from Herat, another western province, to Ghor when they came under attack.

No one immediately claimed responsibility for the attack.

Both the Taliban and militants from the rival Islamic State group are active in Ghor and have previously claimed attacks in the province.
