The formation of the group comes after the government released a report in June, encompassing 144 observations, which said there was a lack of sufficient data to determine the nature of mysterious flying objects.

Deputy Secretary of Defense Kathleen Hicks said in a separate statement the presence of unidentified aerial phenomenon (UAP) in restricted airspace poses a potential safety of flight risk to aircrews and raises potential national security concerns.

The new group which will succeed the US Navy's Unidentified Aerial Phenomena Task Force, will work to detect, identify and attribute objects, assess and mitigate any associated threats, the Pentagon said.
