India and Pakistan have intensified their hostilities over the hotly contested Kashmir region following a massacre of 26 mostly Indian tourists, which New Delhi linked to Pakistan

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.

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.
