'UFO' filmed above protesters in Moscow
An 'unidentified flying object' has been spotted above Moscow during an anti-government protest.
Hundreds of pro-democracy protesters in the Russian capital's Bolotnaya Square witnessed the 'UFO' hover above them on Saturday.
Confused onlookers among the 25,000-strong crowd filmed the strange object on their phones (video below) while some climbed trees in an attempt to get a closer look.
The apparently silent object had pulsating coloured lights with 'pylons' emanating from the body.
Paranormal writer Michael Cohen told the Daily Mail: "NASA recently admitted that there is a good chance that aliens are monitoring our civilization through using 'unmanned' probes.
"'It is highly possible that this craft is one of these and aliens are taking an interest in our political affairs."
However bloggers and social networking sites have offered up more earthly explanations with many users speculating that it is most likely a government surveillance drone or a device similar to the HexaKopter which is used for aerial photography.
The protests are against elections in early December that pro-democracy organisers say were rigged in favour of Vladimir Putin and his United Russia party.
Russia's President Dmitry Medvedev has ordered an investigation into the allegations of voting fraud in an attempt to quell public discontent.
