"The Gool carnage and such incidents present a moral challenge to the Centre," PDP president Mehbooba Mufti said in a statement after visiting families of four persons killed in BSF firing in Ramban district last week.
She alleged government forces were treating people of Jammu and Kashmir as enemies and training their guns on them.
"It is unimaginable that security force deployed primarily for the safety of people could act so atrociously and gun down innocent and unarmed civilians as was done in Gool. It seems people of the state have been deprived of all fundamental rights including right to life, right to expression and even the right to protest," she said.
"Just issuing statements of condemnation and not being able to act against the perpetrators, has resulted in complete collapse of law and order in the state," Mehbooba said.
Demanding an inquiry into acts that led to Gool firing, she said PDP was concerned at the targeting of youths in other areas of Chenab Valley who are being booked by police for holding protests against killings.
