The drone was spotted in the compound of the office of the Indian High Commissioner in Islamabad, Pakistan.
India has strongly objected to the security breach after the drone was spotted over the compound on Friday, NDTV reported.
Last Sunday, a drone strike struck an Indian Air Force base camp in Jammu and Kashmir. A few days later, India became suspicious after seeing a drone in the office of the Indian High Commissioner.
Indian officials suspect that Pakistan may have been involved in the attack on the Indian Air Force base camp.
Violations of security at the Indian High Commissioner’s office are expected to further strain relations between India and Pakistan.
