Moscow: Russia claims its flight records show a Ukrainian fighter jet was flying close to the Malaysian passenger plane just before it crashed and that Kiev was operating radar stations used for missile systems.

Separately, a Russian television program has accused the US Central Intelligence Agency of being behind the downing of flight MH17.

Moscow also denied supplying Ukrainian separatists with Buk missile systems or any other weapons, as it sought to head off international accusations it was responsible for the downing of the plane with 298 people on board.
