The neighboring countries exchanged fire for several days after India's missile attack on Pakistan before reaching a ceasefire on Saturday.

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 on Saturday launched counterattacks against India after three of its air bases were struck overnight, as the conflict between the nuclear-armed neighbours spiralled toward full-blown war.
