The Argentine air force has created a commission to record and investigate reports of unidentified flying objects (UFOs) in the country's airspace.

The Commission for the Investigation of Airspace Phenomenon "is in the process of being formed", captain Mariano Mohaupt said.

Authorities are urging military and civilian pilots to report any experiences with UFOs and, if possible, to send any documenting evidence.

Officials say the air force already keeps records of reported UFO sightings but the new commission will also involve meteorologists, air traffic controllers and civilian pilots.

Other South American countries including neighbouring Brazil and Uruguay have previously moved to record alleged UFO sightings.
