Britain called on Tuesday for calm between Indian and Pakistani communities in London after lawmakers voiced concerns that tensions over a deadly militant attack in India's Kashmir region could spill into the diaspora.

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.
