A giant UFO has been filmed hovering over the Kremlin in Russia by passers by, and experts are so far baffled over the footage. The video, which is now the most viewed video on the Russian Youtube, if genuine can be arguably the best footage yet over the growing evidence of UFO activity.

According to the Daily Mail, the UFO was seen hovering over the Kremlin for a number of hours and was reported by hundreds of people. The UFO is estimated to be up to a mile wide.

The question that strikes us though is that if this was really hovering for a number of hours, why wasn't it filmed by an actual TV news camera crew, and why hasn't it filmed by at least a few of the "hundreds" of witnesses. These questions remain unanswered but do question the events's credability. Judge for yourselves.
