White House Press Secretary Jay Carney said Monday that the U.S. government is prepared to provide support to Ukraine, under certain conditions, as the country tries to emerge from a bloody power struggle that is still in flux. Carney spoke after Ukraine's acting government issued an arrest warrant for President Viktor Yanukovych, accusing him of mass crimes against the protesters who stood up for months against his rule. Carney said that at this point, Yanukovych's whereabouts have not been confirmed but he is not "actively leading the country."
