The United States on Wednesday called on Russia to do more to stop the flow of arms and fighters into eastern Ukraine, even after Russia's Federation Council voted to repeal legislation allowing Russian armed forced on the territory of Ukraine. "We welcome the Federal Council's decision to repeal the resolution authorizing the Russian military force in Ukraine. The repeal is a step in the right direction ... But we really need Russia to do more," State Department deputy spokeswoman Marie Harf told reporters. "We are aware that a number of Russian combat units have deployed to locations close to the Ukrainian border. This is not in keeping with the Russian intent to de-escalate the situation," Harf added.
