The central government is planning to harden its stance against Kashmiri separatist leaders who are spearheading an unending street unrest in the valley for the past two months, according to Home Ministry sources here.

The sources said the government was considering to review its policy on their security, medical treatment and foreign trips.

The review comes after separatists hardened their stance over their demand for right to self-determination and refused to hold talks with a group of opposition MPs who were in Jammu and Kashmir as part of an all-party delegation from Delhi.

Home Minister Rajnath Singh earlier briefed Prime Minister Narendra Modi on the visit of the all-party team and the situation in the troubled valley where 75 persons have been killed and over 12,000 injured in the aftermath of the July 8 killing of Hizbul Mujahideen commander Burhan Wani.
