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.

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.
