Pakistan imposes curfew after sectarian riots

Authorities imposed a curfew in a city in northern Pakistan today after gunmen injured a minority Shiite Muslim leader, sparking a riot, residents and a senior government official said.

Hundreds of supporters of Agha Ziauddin, a prominent Shiite leader, blocked main roads in the Himalayan city of Gilgit, about 150 miles north of the capital, Islamabad, and attacked shops owned by Sunni Muslims.
