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

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.

Police in India's Kashmir published notices on Thursday naming three suspected militants "involved in" the attack on tourists this week in which 26 people were killed, and announced rewards for information leading to their arrest.
