At least 26 people were killed and 17 others wounded when gunmen opened fire on tourists in Indian-controlled Kashmir, the worst assault in years targeting civilians in a restive region that has seen an anti-India rebellion for more than three decades.

Kashmir Police on Thursday named three suspected terrorists in the April 22 Pahalgam attack that killed 26 people. Two are reportedly Pakistani nationals, according to Reuters. Authorities have also announced cash rewards for any information leading to their arrest,

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.
