DAVOS (Sputnik) — In October, US and Russian officials signed a memorandum of understanding concerning safety procedures for the two countries’ respective air missions in Syria to avoid any conflicts.
"We have a memorandum of understanding with the Russians with regard to fly operation in Syria, and that is the extent of our cooperation," Cook said on the sidelines of the economic forum in Switzerland’s Davos.
Since September 30, Russia has been conducting an aerial campaign in Syria against the Daesh extremist group, which is outlawed in Russia, following a request from Syrian President Bashar Assad.
Meanwhile, a US-led coalition of more than 60 nations has been carrying out airstrikes against Daesh in Syria since September 2014, without the approval of the Syrian government or the UN Security Council.
