Ukraine's counterintelligence claims it has photographic evidence that points to the Russian-backed separatists as the ones who shot down Malaysia Airlines flight MH17.

In a briefing at the Ukraine Crisis Media Center, head of Ukraine's Security Service (SBU), counterintelligence department Vitaliy Nayda claimed photo materials show two BUK-M1 missile systems crossed the border from Ukraine into Russia on July 18 - the day after MH17 was shot down.
