Russian UFO

Strange Explosion in Russia

Reports of ufo activity and sightings in Krasnoyarsk Russia were followed by this unexplained flash of white light, reminiscent of the phoenix mystery flash that was caught on a traffic cam a couple of weeks back. However, this flash was much brighter, with some witnesses comparing it to a nuclear blast. Many people were horrified and shaken by the experience and there is no official explanation yet. Was it UFO related? Or something else?
