NEW DELHI — A deadly attack on tourists in Indian-controlled Kashmir has again moved India and Pakistan closer to war as the two rivals downgraded diplomatic and trade ties, closed the main border crossing and revoked visas for each other’s nationals.

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.

Tuesday's bloodshed in Pahalgam - where at least 26 tourists were killed in a hail of gunfire - marks the deadliest militant attack in Kashmir since 2019. The victims weren't soldiers or officials, but civilians on holiday in one of India's most picturesque valleys.
