As the crisis in Ukraine deepens, Secretary of State John Kerry said Tuesday the U.S. and the Europe

(29 Jul 2014) FOR CLEAN VERSION SEE STORY NUMBER: apus014594 The United States said Russia has "not shown a shred of evidence" that it is willing to help end the violence between the Ukraine separatists backed by Moscow and the government that is trying to maintain its sovereignty. Secretary of State John Kerry on Tuesday issued a new warning that the U.S. and European Union are prepared to slap additional sanctions on Russia if it continues to ship weapons, funds and fighters across its border to support the separatists in eastern Ukraine. He said the fighting between the separatists and Ukraine's military has prevented investigators from obtaining necessary evidence - and even remaining body parts - from the crash site of Malaysia Airlines Flight 17, which was shot down nearly two weeks ago. "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 following a State Department meeting with Ukraine Foreign Minister Pavlo Klimkin. Kerry cited "clear evidence" of Russian military support to the separatists, including rocket and artillery fire from Russia into Ukraine. Kerry said Putin "can make a huge difference here if he chooses to." But in the meantime, he said the U.S. and it's European allies would "take additional measures and impose wider sanctions on key sections of the Russian economy."
