US officials have released new classified documents and videos about mysterious aerial objects, including a video of a spherical object moving rapidly over a populated area in the Middle East.

In the short video released, a round-shaped object can be seen speeding over a residential area.

According to the authorities, unusual features were observed in the round object which could not be fully explained based on the available information.

Researchers have also been unable to determine whether the object was a type of drone, balloon, airplane, or any other known spacecraft, which is why the incident remains unsolved.

US officials have made it clear that declaring an event unsolvable is not proof of the existence of extraterrestrials.

According to them, this could simply mean that the information needed to reach a definitive conclusion was not available.

The incident is among dozens of newly released aerial observation reports of unusual aerial objects recorded by military equipment and surveillance systems.

Some reports have also revealed other mysterious sightings, including spherical objects.

According to US officials, more documents and records related to the unidentified air incidents may be released in the coming months.

Officials say many incidents are later linked to normal aircraft or equipment malfunctions, but some remain unsolved.
