Russia says ready to resume U.S. military talks on Syria air safety: U.S.

NAVAL AIR STATION SIGONELLA, Italy (Reuters) - Russia has told the United States that it is ready to resume military-to-military discussions aimed at keeping aircraft from the former Cold War foes apart as they wage parallel campaigns of air strikes in Syria, a U.S. official said on Tuesday. U.S. Defense Secretary Ash Carter had earlier on Tuesday called on Moscow to urgently respond to proposed rules for air-to-air conduct over Syria. (Reporting by Phil Stewart; Editing by Hugh Lawson)
