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.

Pakistan's military says it has launched retaliatory strikes on sites in India, alarming world powers about further hostilities between the nuclear nations.

Tensions between India and Pakistan remain high days after Delhi launched airstrikes at its neighbor, sparking tit-for-tat military action from both sides and widespread confusion as competing claims and disinformation spread online.
