The US Department of Defense has announced plans to form a new UFO investigation unit.
The Airborne Object Identification and Management Synchronization Group (AOIMSG) will combine efforts from across the US government to "detect, identify and attribute objects of interests" in restricted airspace and "to assess and mitigate any associated threats".
The Pentagon said "incursions by any airborne object" into restricted airspace "pose safety of flight and operations security concerns, and may pose national security challenges".
"DOD [Department of Defense] takes reports of incursions – by any airborne object, identified or unidentified – very seriously, and investigates each one," it said in a statement.
Watch: Footage released last year shows fast moving 'unidentified' flying object caught on camera by US Navy.
The AOIMSG will replace the US Navy's Unidentified Aerial Phenomena Task Force - established in August 2020.
Last year, the US Navy released footage of "unidentified" flying objects.
The videos, one of which dates from November 2004 and two from January 2015, were already in the public domain after unauthorised releases in 2007 and 2017.
At the time, the Pentagon said they released the videos "to clear up any misconceptions by the public on whether or not the footage that has been circulating was real, or whether or not there is more to the videos".
