A senior Russian diplomat said today (May 5, 2017) that United States and allied aircraft will be banned from flying over much of Syria in a deal between Iran, Russia, and Turkey, according to the NY Times website.
The diplomat, Aleksandr Lavrentiev, also suggested that Russian and Turkish warplanes would be prohibited from flying in four designated "de-escalation zones," where Syrian government and rebel forces are supposed to stop fighting each other.
But Lavrentiev sketched out a broader geographical no-fly zone for American and coalition military planes. He said they would be allowed to fly only in eastern Syria over Islamic State (IS) controlled areas, apparently excluding the entire western region of the country.
There was no immediate comment from the American military or from the Trump administration on the Russian order.
