At least 10 people have been killed in sectarian violence in the northern Pakistani city of Gilgit on Saturday.
A 24-hour curfew has been imposed in the city
The shooting of a Shia Muslim cleric earlier sparked clashes between his supporters and Sunni Muslims in the Himalayan city, officials said.
Authorities have imposed a curfew and called for troops to help restore order in the city, some 250km (150 miles) north of the capital Islamabad.
The region's chief administrator did not say when the curfew would end.
