Indian Prime Minister Narendra Modi vowed on Thursday to pursue, track and punish terrorists and their backers in a strong reaction to a deadly militant attack on tourists in Kashmir, where police have identified two of the gunmen as Pakistani.

The Pakistani government announced a series of sweeping retaliatory measures a day after India took aim at its neighbor and archnemesis.

Tuesday's bloodshed in Pahalgam - where at least 26 tourists were killed in a hail of gunfire - marks the deadliest militant attack in Kashmir since 2019. The victims weren't soldiers or officials, but civilians on holiday in one of India's most picturesque valleys.
