John Kerry: "Everything that we’ve seen in the last 48 hours from Russian provocateurs and agents operating in eastern Ukraine tells us that they’ve been sent there determined to create chaos. And that is absolutely unacceptable. These efforts are as ham-handed as they are transparent, frankly. And quite simply, what we see from Russia is an illegal and illegitimate effort to destabilize a sovereign state and create a contrived crisis with paid operatives across an international boundary engaged in this initiative."
