Censor.NET citing the Washington Post reports that Obama noted that "we don't yet know exactly what happened with respect to the Malaysian Airlines, although obviously we're beginning to draw some conclusions given the nature of the shot that was fired. There are only certain types of anti-aircraft missiles that can reach up 30,000 feet and shoot down a passenger jet. We have increasing confidence that it came from areas controlled by the separatists.
But without having a definitive judgment on those issues yet, what we do know is, is that the violence that's taking place there is facilitated in part -- in large part -- because of Russian support, and they have the ability to move those separatists in a different direction. If Mr. Putin makes a decision that we are not going to allow heavy armaments and the flow of fighters into Ukraine across the Ukrainian-Russian border, then it will stop. And if it stops, then the separatists will still have the capacity to enter into negotiations and try to arrive at the sort of political accommodations that Mr. Putin himself says he wants to see. He has the most control over that situation, and so far, at least, he has not exercised it."
Obama stated that US may toughen the sanctions against Russia: "we will continue to make clear that as Russia, you know, engages in efforts that are supporting the separatists, that we have a capacity to increase the costs that we impose on them, and we will do so -- not because we're interested in hurting Russia for the sake of hurting Russia, but because we believe in standing up for the basic principle that a country's sovereignty and territorial integrity has to be respected, and it is not the United States, or Russia, or Germany, or any other country that should be deciding what happens in that country."
