As world powers face multiple crises, the one set off by a terror attack in Kashmir is getting scant attention, and little help de-escalating between two nuclear-armed neighbors.

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. Pakistan denies it was behind Tuesday's attack by gunmen on a group of tourists in Kashmir.

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.
