Indian authorities say they have imposed an indefinite curfew in parts of an Indian Kashmir city after clashes with hundreds of Sikh protesters after bullets fired by police kill one person and injure two more.

Police fired at the stone-throwing protesters on Thursday after tear gas and warning shots failed to quell them in Jammu, the winter capital of Indian Kashmir, an officer said on condition of anonymity because he was not authorized to talk to reporters.

The Sikhs were protesting the tearing away of posters of slain militant leader Jarnail Singh Bhindranwale by police in Jammu ahead of the anniversary of his death Saturday.

Militant Sikhs waged a guerrilla war in 1980s for an independent homeland in neighboring Punjab state. Many Sikhs live in Indian Kashmir.
