Later, in the northern Kashmiri town of Sobore, police opened fire to quell stone-pelting protesters. One person was critically injured and later died in hospital, police said.

The protests, triggered by allegations of the desecration of the Quran in the United States, quickly turned into the violent anti-India demonstrations that have taken place all summer in India's restive Kashmir region.

So far this summer, 89 people have died in anti-India demonstrations in Kashmir, the predominantly Muslim part of Jammu and Kashmir state where many favor severing ties with New Delhi.

Divisional Commissioner Pawan Kotwal told CNN that protesters tried to burn down another school run by Christian missionaries in Mendhar, a Muslim town southwest of Srinagar that is in the predominantly Hindu area of the state.

He said an indefinite curfew has also been imposed in Mendhar.
