(CNN) – U.S. officials say a Russian fighter jet made a dozen low-altitude passes on the USS Donald Cook in the Black Sea this weekend, in what could be the most direct confrontation between the United States and Russian forces in years.
Officials say the plane appeared to be unarmed, but the Pentagon is still calling the fly-by "provocative and unprofessional."
And if that's not reminiscent enough of the Cold War, CIA Director, John Brennan was in Kiev this weekend, a fact confirmed today by White House Press Secretary Jay Carney, even though the Central Intelligence Agency had already refused to comment on Russian media reports that Brennan was there.
Meanwhile, the crisis on the ground threatens to spill over. Pro-Russia protesters have control of the police headquarters of another eastern Ukrainian city, and are refusing to blink, as the ultimatum from the Ukrainian government passed without consequence.
