KIEV (Reuters) - Ukraine’s Foreign Minister Pavlo Klimkin said on Friday that arms negotiations were ongoing with the United States.

Asked about the prospect of the U.S. selling lethal weapons to Ukraine, Klimkin said: “We are now conducting such negotiations. I cannot talk about individual systems. This is a confidential issue.”
