Washington (CNN) -- A classified U.S. intelligence analysis says it is most likely that pro-Russian separatists in eastern Ukraine fired the missile that downed Malaysia Airlines Flight 17, CNN has learned. A U.S. defense official with direct access to the latest information detailed the analysis to CNN but declined to be identified because of the sensitivity of the information. The preliminary analysis concludes the missile was from a Russian-made Buk system, known as the SA-11 among NATO forces, the official said. U.S. military intelligence analysts concluded only the SA-11 or the SA-20 has the warhead, range and ability to shoot down an airliner, the official said.
