Shehbaz Sharif says Pakistan responded to India's air strikes by downing Indian jets, a claim Delhi has not confirmed.

Tensions have risen between the nuclear-armed neighbors since an attack on Hindu tourists in Indian Kashmir last month.

Video footage shows a bright flash from the residential Islamic seminary outside Bahawalpur in central Pakistan as India attacked its neighbor.

The Pakistani claims come amid an escalating military standoff that flared up late Friday night after Pakistan launched a series of drone attacks on 26 locations across India, spanning from Jammu and Kashmir to Gujarat.

Pakistan says it will avenge those killed by India’s missile strikes that New Delhi called retaliation for last month’s massacre of Indian tourists.

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.
