As I explained in detail, SBU head Valentyn Nalyvaychenko asserted that the Boeing 777 was shot down by a Russian-supplied "Buk' (SA-11) surface-to-air missile system, but in error: Moscow planned to down an Aeroflot plane that was nearby, in a false flag provocation to justify the Kremlin's direct intervention in the war for eastern Ukraine, but in a tragic mistake the bumbling separatists downed the Malaysian airliner instead, killing 298 innocent people.
