EXTRAORDINARY pictures and video of a green-tailed UFO over Siberia have left experts disagreeing over what it actually was.
Social media buzzed with claims of visitors from outer space.
Some witnesses posted: “Maybe aliens?” and “soon there will be reports about mutants”.
But local experts disagreed sharply over the unidentified flying object (UFO) seen low in the sky.
One eyewitnesses posted online that “a comet fell from the sky – it was glowing bright green and quite large.”
Another said: “At 7.30pm in the sky a comet or a meteor was flying. There was a powerful flash. Who else saw it?”
A third said: “A strange flash in the sky – looked like a comet with a green tail.”
Some believed it may have exploded over or close to Lake Baikal, a version backed by the head of a major nature reserve Mikhail Ovdin.
He said: “In the area of Goryachinsk we saw a sharp light of bright green colour.
The UFO has had opinion divided on it being a meteor or manmade
“It flew within five seconds, and disappeared over Lake Baikal. I think it burned down in the atmosphere.”
The head of the Astronomical Observatory at Buryat State University in Ulan-Ude, Liliya Mironova, insists the object was manmade.
She said: “I myself did not witness the incident, but I saw the videos.
“I can say with certainty that it was not a meteorite, nor a meteor or a comet.
“It is clear that we are talking about some sort of man-made object.
The UFO was likely to be a meteor burning up in the atmosphere, say experts
