MCGOVERN SHARES CONTEXT ON PLANE SHOOTDOWN
Barack Obama claims the US has firm evidence that the plane was shot down by a missile, fired from an area controlled by anti-Kiev fighters. He also accuses Russia of supporting them. Nevertheless US president agrees to Putin's calls to conduct transparent investigation and says it's too early to say who and why shot down the plane. Ex-CIA analyst Ray McGovern see the situation as isolation for President Poroshenko.
