The author (Adrij Mendierej) of the video of the plane crash which killed the Polish top brass and the Polish president was stabbed near Kijow, and transported in critical condition to the Kijow hospital. Three unidentified individuals unplugged him from his life support system and stabbed him a further three times, it is alleged.
The video that the author released was deleted from youtube, but a copy is now available (below). Four gunshots can be heard towards the end of the video, and speculators have said that these were shots by the military, finishing off any survivors of the crash. The Polish State prosecutor is now examining this issue.
