EERIE footage showing a mysterious black ring floating in a clear blue sky before vanishing has sparked UFO rumours.
The strange shape hovered ominously above the village of Shorthandy, near Astana in Kazakhstan, as stunned locals watched-on.
After circling the sky for several minutes it disappeared completely, leaving no trace behind.
Residents spotted the mysterious phenomenon on Saturday morning.
The video has been viewed and shared thousands of times on various sharing sites with users all speculating as to what could have caused the spooky sight.
While some are convinced the shape is a UFO and proof of extra-terrestrial life, others are slightly more sceptical, saying it could be the result of cigarette smoke.
The clip has been watched on YouTube almost 50,000 times.
One viewer wrote: «A vortex ring or smoke ring can be formed in the atmosphere by a rising (falling) mass of warm (cold) air, which is also called a thermal (microburst).
«It could have been artificially created as well.»
