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.

At least 26 people died and 17 others were injured when suspected militants opened fire at a popular tourist spot in the Pahalgam region of India's Jammu and Kashmir territory this week.

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.
