Russia and the United States will continue their contacts at the working level on Syria, Russian Defense Minister Sergei Shoigu said. 
"It [the interaction mechanism] cannot but work and the contact is so close that we can't but work," the Russian minister said. "We have had and continue contacts at the working level," Shoigu said. "In this regard, we primarily rely on the need to ensure the safety of our pilots and, naturally, of all those who operate in that sky," Shoigu said. 
The air regime has become tighter and "now it is of different, inquiring nature whereas earlier it was of the notifying mode," the defense minister said.
Chief of the Main Operational Directorate of the General Staff of the Russian Armed Forces Lt.Gen. Sergei Rudskoy said last week that Russian and US forces are still in direct contact to coordinate flights in the Syrian skies, despite the suspension of the bilateral memorandum of understanding on "Safe Flights Over Syria".
Rudskoy stressed that direct contacts at the working level are continuing between the two sides, in order to ensure the safety of Russian and US aircraft operating in the Syrian skies, expressing hope to settle differences between Moscow and Washington in the future and strengthen joint action.
