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.

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.

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.
