MOSCOW (Reuters) - President Vladimir Putin told U.S. President Barack Obama on Sunday Crimea's referendum on union with Russia was legitimate and expressed concern about Kiev's failure to stamp out violence against Russian speakers in Ukraine.
"Vladimir Vladimirovich Putin drew attention to the inability and unwillingness of the present authorities in Kiev to curb rampant violence by ultra-nationalist and radical groups that destabilise the situation and terrorise civilians, including Russian speaking population," the Kremlin said.
