Meanwhile, fire was exchanged along the Line of Control (LoC), the 740km (460-mile) de facto border separating the Indian and Pakistani-controlled areas of Kashmir, for a fifth straight night. Pakistan said it had downed a drone, with fears of an escalation between the nuclear powers bubbling.

“Pakistan has successfully shot down an Indian quadcopter along the Line of Control, thwarting a violation of its airspace,” PTV reported, citing unnamed military sources. There was no reaction from New Delhi on the claim as of 1200GMT.
