"The demand for a judicial probe has lost its meaning... the government must now ensure that the culprits (behind the firing) are identified and booked without any time buying tactic," state secretary of CPI(M) M Y Tarigami said in a statement here.
The BSF and the police authorities should unconditionally apologise to the families of victims and cooperate in the probe, he said.
"The killings reportedly at the hands of BSF and police are not only barbaric but also yet another instance of utter failure of the security establishment to rein in their forces and make them adhere to law of the land," Tarigami added.
The incident took place when a mob attacked a BSF camp in Ramban to protest alleged high-handedness of a patrolling party.
