Suspected separatists killed two soldiers and one police officer in an ambush on a convoy overnight in Indian held Kashmir, an official in the troubled region said on Wednesday.
Military convoys happen to be going more often through the area at night in recent weeks in order to avoid falling upon protesting residents.
Kashmir continues to be under curfew since demonstrations erupted in a gunfight with security forces, over the departure of a popular youthful rebel leader, Burhan Wani.
More than 60 civilians are killed in battles between security forces and protesters, and thousands more injured in the worst violence.
Kashmir is split along an UN-monitored line of control between India and Pakistan, but both claim it in full and have fought two wars over its control.
Armed rebels and Indian security forces have fought for the independence of the area or for it to be made part of Pakistan. The conflict has left tens of thousands, mainly civilians, dead.
Gunmen shot and wounded 10 authorities paramilitiaries on Monday who were attempting to impose a curfew in Srinagar during Independence Day. Among the troopers later died of his injuries.
