India has summoned the top Pakistani diplomat in New Delhi, local media reported on Thursday, a day after it announced measures to downgrade ties with Islamabad as relations between the nuclear-armed rivals plummeted following a deadly militant attack in Kashmir.

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.

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.
