Secretary of State John Kerry today told a Senate Committee that the seizure of government buildings in three East Ukrainian cities has been fomented by Moscow. "And equally as clear, must be the reality that the United States and our allies will not hesitate to use 21st century tools to hold Russia accountable for 19th century behavior." At the hearing, Kerry and John McCain exchanged harsh words over the US reaction to what’s happening in Ukraine. Roland Oliphant is there for the Daily Telegraph.
