Astonishing video footage of what looks like a cluster of UFOs flying in unison over Moscow has been declared authentic by experts.
The film - shot in Russia's capital at the end of last month - shows four unidentified lights hovering and swooping above the city in what looks like synchronised flying.
Mysterious: Experts declare UFO footage authentic
Thousands of people have now viewed the images across the county, which seem to show the objects moving at great speed and then hovering in formation.
The man who filmed the Close Encounters-style spectacle, named only as Timur in local media, explained: "There were four balls of light. A red one to the left, two white ones in the middle and a less bright one to the right."
He added: "Sometimes the one on the right would disappear and come back. All together, they made the geometric shape of a rhombus."
And he dismissed some critics' claims that the lights could be a reflection of lights on the ground.
Timur explained: "I’ve been living in the district for two years, and have never seen anything like that before."
Now Russian UFO expert Vadim Chernobrov has confirmed that he believes the footage is genuine.
He explained: "The lights cannot be explained as either an atmospheric or a cosmic image.
"The chance of it being some sort of mirage is also impossible due to the precise geometric shape the objects have formed."
Chernobrov added: "Some have said they could look like Chinese lanterns but I would dismiss this possibility because of the movements and speed of the objects."
