Russia says ready to resume US military talks on Syria air safety

NAVAL AIR STATION SIGONELLA - 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 US official said on Tuesday.
US Defense Secretary Ash Carter had earlier on Tuesday called on Moscow to urgently respond to proposed rules for air-to-air conduct over Syria.
