Indian and Pakistani soldiers have exchanged heavy volleys of shells and gunfire across their frontier in Kashmir, killing at least five civilians in a growing military standoff. Police in Pakistan say an unusually intense night of artillery exchanges left at least four civilians dead and wounded 12 others in areas near the Line of Control that divides Kashmir. In India, military officials said Pakistani troops barraged their posts overnight with artillery, mortars and gunfire at multiple locations. A woman was reported killed and two other civilians were injured.

Pakistan said Indian drones killed two civilians and wounded four soldiers, as India accused its neighbor of attempting its own attack. India acknowledged Thursday that it targeted Pakistan's air defense system, and Islamabad said it shot down several drones. India said it "neutralized" Pakistan's attempts to hit military targets. It was not possible to verify all of the claims. The exchanges came a day after Pakistani officials said Indian missiles killed 31 civilians. New Delhi said it was retaliating after gunmen killed 26 people, mostly Hindu tourists, in India-controlled Kashmir last month.
