Although police did not spell out the reason for the sudden restrictions in five police station areas of the old city, administration officials said they apprehended violent protests following the killing of Sajid Ahmad Gilkar.
"Restrictions have been imposed in the police station areas of Maharajgunj, Safakadal, Rainawari, Nowhatta and Khanyar as a precautionary measure to maintain law and order," a police official said.
Three Hizbul Mujahideen militants, including Gilkar, was killed after an overnight gunbattle with security forces in Budgam's Redbugh area this morning, police said.
The other two slain militants have been identified as Aaqib Gul of Gooripora and Javaid Ahmad Sheikh of Beerwah.
