Anton Gerashenko says on his Facebook page the plane was flying at an altitude of 10,000 meters (33,000 feet) when it was hit Thursday by a missile fired from a Buk launcher.
A similar launcher was seen by Associated Press journalists near the eastern Ukrainian town of Snizhne earlier Thursday
According to MSNBC, Russia is denying involvement.
9:22 AM PT: NBC's Jim Miklaszewski says U.S. officials are pursuing the theory that the plane was shot down as "a likely option" but haven't reached any conclusion. If the plane was shot down, he says, U.S. officials believe that in that region, only the Ukrainian and Russian militaries have the missiles required to shoot down a plane flying at that altitude.
