Mysterious images show what appears to be a UFO flying in the sky over western Siberia.
Russian experts are analyzing images of the bright spherical shape that crosses the sky above the oil cities of Surgut and Nefteyugansk amid disagreements over the dramatic phenomenon.
Several witnesses caught the "bright green ball" on the tape and posted it online.
A major Russian television network claimed that the UFO was "a meteorite or extraterrestrial." The spherical orbs, shining with light, were seen throughout the Russian province.
Other theories were a Russian missile or space rocket, but Russian emergency officials said there had been no reports of meteorites or other mysterious objects falling to the ground.

A major Russian television network claimed that the UFO, also described as "yellow," was "meteorite or aliens."
Some experts insisted that the most likely explanation was a Perseid meteor shower, common at this time of year.
But Professor Mikhail Larionov of the Federal University of the Urals insisted that it was unlikely to be a meteor because it seemed to be "too slow" in the images.
"The trajectory of the fall of the object is quite flat and its speed is quite slow," he said.
"From this, we assume that this was the burning of space debris."
"The Chelyabinsk meteorite in 2015 had crossed the sky at a much higher speed," he said.
The Chelyabinsk meteor was a superbolid caused by a near-Earth asteroid of about 20 meters that entered the Earth's atmosphere above Russia and crashed into the earth leaving a hole six meters wide in the ground.
Meteorites fall between 6 and 45 miles per second. But according to Larionov, this UFO traveled less than 5 miles per second.
