Police and CRPF personnel have been deployed in these areas as well as other major towns in Kashmir valley as a precautionary measure, the officials said.
Separatists have asked the people to stage peaceful demonstrations after Friday prayers to protest against the killings.
The prohibitory orders were invoked after the youth was killed in the CRPF firing on protestors outside Gagran camp of the force, while 13 others suffered pellet injuries.
The protestors were demanding removal of the camp and arrest of the personnel involved in firing incident last week that left four persons dead including three civilians.
The state government yesterday ordered a magisterial probe into the death of five persons in Shopian and directed the District Magistrate to submit the report within one month.
The Government also directed DGP Ashok Prasad to replace the CRPF personnel at Gagran camp with Jammu and Kashmir Armed Police.
