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

The Pakistani government said it did not want an escalation, but in the wake of a deadly attack in Indian-controlled Kashmir by unidentified militants, analysts warned of an unpredictable situation.

Relations between India and Pakistan are cratering following a deadly attack in the disputed Himalayan region of Jammu and Kashmir that left more than two dozen tourists dead, raising fears of military escalation between the nuclear-armed rivals.
