In the days since, tensions have risen dangerously between India and Pakistan, which have fought two of their three wars over Kashmir.

Relations between India and Pakistan are cratering following a deadly militant attack in Indian-administered Kashmir that has sparked tit-for-tat reprisals and raised fears of another military escalation between the nuclear-armed rivals.

Troops from Pakistan and India exchanged fire in disputed Kashmir for a third night in a row, officials said, as relations between the nuclear-armed rivals plunged to their lowest level in years.
