"While the Russians have said that they want to de-escalate the conflict, their actions have not shown a shred of evidence that they really have a legitimate desire to end the violence and end the bloodshed," Kerry said after a meeting with Ukrainian Foreign Minister Pavlo Klimkin at the State Department.
