The barrage came amid increased tension between the nuclear-armed rivals.

In August, India withdrew Kashmir’s semiautonomous status, shut down communications in the region and detained thousands of people. The moves incensed Pakistan, which considers itself the defender of Kashmiri Muslims.

India accuses Pakistan of stoking a three-decade insurgency against Indian rule in Kashmir by sending fighters and arms across the Line of Control. Pakistan denies the accusations.

Five civilians and one soldier were killed on Pakistan’s side of the Line of Control, a spokesman for the Pakistani army said Sunday. Two Indian soldiers and one civilian were also killed, a spokesman for the Indian Defense Ministry said.

India and Pakistan claimed to have killed larger numbers of the other country’s soldiers in the incident, but such assertions could not be verified independently.

Gen. Bipin Rawat of the Indian Army told reporters that the exchange began when militants attempted to cross into Indian-controlled territory. Pakistan rejected the accusation and said India’s firing was “indiscriminate and unprovoked.”

Exchanges of fire across the Line of Control have increased in recent years, an ongoing confrontation that some analysts have called a “war by other means.”

The two countries reached a cease-fire agreement in 2003, and for several years, relative calm prevailed on the de facto frontier in Kashmir. Since 2014, however, cease-fire violations have jumped.
