The Indian military says Pakistani soldiers fired at Indian posts all along the highly militarized frontier in disputed Kashmir as tensions flare over attack on tourists.

The clash took place just days after a terror attack killed 26 people on the Indian side of the disputed region, raising tensions between the two nuclear-armed nations.

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.
