At least five suspected fighters have been killed in a fierce exchange of fire between a group of armed men and New Delhi’s security forces in disputed Indian-administered Kashmir.

Indian officials say soldiers and police launched an operation early Friday based on intelligence that a group of militants were present in the Kangan region.

Military sources say troops suffered no casualties during the fierce clashes in the disputed region. No separatist group has commented on the incident.

Kashmir has been the scene of violent clashes in recent years. Indian troops are in constant clashes with the militants seeking independence in the area.

Authorities have deployed large police and paramilitary troops in most parts of the capital, Srinagar, and several other major cities to prevent street demonstrations.

The government forces have responded by imposing curfews and restrictions on the movement of people.

Kashmir lies at the heart of more than 60 years of hostility between India and Pakistan. Both neighbors claim the region in full but have partial control over it.

The neighbors agreed on a ceasefire in 2003, and launched a peace process the following year. Since then, there have been sporadic clashes, with both sides accusing the other of violating the ceasefire.

India and Pakistan have fought three wars since their independence from Britain in 1947 — two of them over Kashmir.

Since 1989, an armed uprising and a subsequent crackdown by Indian forces has killed thousands of people in the Muslim-majority region.
