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.

India has yet to present clear evidence of who conducted the attack on April 22nd that killed 26 mostly Hindu men in Pahalgam, a popular tourist spot in the Muslim-majority region. But local police are searching for two Pakistani suspects and one Indian.

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