India accused Islamabad of supporting "cross-border terrorism." Pakistan has denied the accusation and a previously unknown militant group calling itself Kashmir Resistance has claimed responsibility for the attack.

It was the deadliest attack against civilians in years in Kashmir, a region claimed by both India and Pakistan that has been racked by violence for decades.

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.
