ISLAMABAD, Pakistan (AP) — Pakistan said India fired missiles at three air bases inside the country Saturday but most of the missiles were intercepted and that retaliatory strikes on India were underway. It’s the latest escalation in a conflict triggered by a massacre last month that India blames on Pakistan.

Earlier on Thursday, India said it had struck Pakistan's air defences and "neutralised" Islamabad's attempts to hit military targets in India on Wednesday night. Pakistan called that action another "act of aggression",

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.

The neighbors have been in conflict over the disputed border region since their independence and partition in 1947.

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.
