U.S. rejects Crimea referendum, warns Russia of imminent sanctions

(Reuters) – The United States warned Russia on Sunday that Western sanctions were imminent and Moscow would pay an increasing price for its military intervention in Ukraine as the White House rejected a referendum in the Crimea region that it was powerless to stop.

With Washington and its European allies expected to unveil coordinated punitive measures against Moscow as early as Monday, U.S. Secretary of State John Kerry told Russian Foreign Minister Sergei Lavrov that Russia must pull its forces in Crimea back to their bases.
