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.

Pakistan called India's actions “irresponsible" and canceled visas for Indian nationals, suspended all trade with India and closed its airspace to Indian aircraft.

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.
