U.S. Secretary of State John Kerry (R) and Ukrainian Foreign Minister Pavlo Klimkin attend a joint news conference at the State Department in Washington D.C., capital of the United States, July 29, 2014. "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.
