JAIPUR, India — Indian prisoners stoned to death a Pakistani inmate in a jail on Wednesday amid mounting tensions over a suicide bombing that Delhi has blamed on its arch-rival neighbor, an official said.

The Pakistani had been eight years into a life term at Jaipur Central Jail in the western state of Rajasthan when he was attacked.

He was stoned to death after a quarrel, Rajasthan state director general of police Kapil Garg said.

The killing came amid calls for retribution across India over a car bombing in Kashmir last Thursday, which killed at least 40 Indian paramilitaries.

Pakistan-based militant group Jaish-e-Mohammed (JeM) has claimed responsibility for the attack. India has accused Pakistan of backing the militants but Islamabad has denied any role.

India and Pakistan, which each control sectors of Kashmir, have been bitter rivals since their independence from Britain in 1947.
