A day after the U.N. appealed for restraint following Tuesday's deadly attack in Indian-administered Kashmir, India reported an exchange of fire across the de facto border in the disputed region.

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.

Pakistani soldiers fired at Indian posts along the highly militarized frontier in disputed Kashmir for a second consecutive night, the Indian military said Saturday, as tensions flared between the nuclear-armed rivals following a deadly attack on tourists last week.
