In Russia, drones are being used to detect illegal immigrants for the first time.
One such incident occurred during a raid in Krasnodar. Rosgvardiya fighters inspected a construction site and monitored the exit of all workers to the street with the help of a quadcopter.
As a result of the inspection, 14 foreigners were found to be working illegally in Russia. They will be required to pay a fine and then be deported from the country.
