Pakistan’s air defense system shot down an Indian drone early Thursday in the eastern city of Lahore, according to Pakistani officials, as India evacuated thousands of people from villages near the two countries' highly militarized frontier in the disputed region of Kashmir.

The attack follows a series of drone strikes by Pakistan in Rajasthan and other border areas, leading to heightened security alerts in India’s border regions.

Amid fears of further escalation, Pakistan said it shot down 16 drones Thursday, while India said it targeted an air defense system in Lahore.
