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.

India launched multiple Israeli-made Harop drones targeting Pakistan overnight and into Thursday, with one damaging a military site and wounding four soldiers, a Pakistani army spokesman said.
