Two of them belonged to Kashmiri separatist group Hizbul Mujahideen while the other two were Pakistan-based Lashkar-e-Taiba (LeT) operatives, the police said.
Shops, public transport and other business establishments remained closed.

Kashmir Valley was tense on Monday, a day after eight people including four local militants, two Army jawans and two civilians were killed and almost twenty people were injured in a fierce gunfight and subsequent clashes between irate crowds and security forces in a remote village of southern Kulgam district.
Two army soldiers were also killed in the gunfight. One man died and about 12 were injured when the security forces opened fire on the crowd.
The Valley-wide strike called by the separatist leadership to protest the deaths evoked mixed response. The National Conference demanded an investigation into the encounter.
