Bloomberg has reported Ukrainian Interior Minister adviser Anton Gerashchenko on his Facebook confirming that the plane has been hit by a missile and crashed near the eastern town of Torez.
The Interfax report said the plane came down 50km short of entering Russian airspace.
It "began to drop, afterwards it was found burning on the ground on Ukrainian territory," the unnamed source said.
The plane appeared to have come down in a region of military action where Ukrainian government forces are battling pro-Russian separatists.
