The world's first drone war between nuclear-armed neighbours has erupted in South Asia. On Thursday, India accused Pakistan of launching waves of drones and missiles at three military bases in Indian territory and Indian-administered Kashmir - an allegation Islamabad swiftly denied.

The two nuclear powers accused each other of drone attacks on military targets as tensions between these neighboring nations rise.

Pakistan accused India of launching air-to-surface missiles that targeted at least three bases. Soon after, Pakistani officials said retaliatory action against Indian bases had begun.
