Multiple blasts were heard in Jammu city in Indian Kashmir for the second day on Friday, and projectiles seen in the night sky after a blackout, two Reuters witnesses said.

Explosions and sirens were reported in parts of Jammu and south Kashmir, and several areas experienced power outages, according to officials.

Blasts rang out across Indian Kashmir and the Sikh holy city of Amritsar in neighbouring Punjab state late on Friday, with the Indian military saying it was shooting down drones in the worst fighting with Pakistan in nearly three decades.
