Since January 21, Moscow has conducted six massive air attacks on terrorists besieging the province's capital. The latest air raid took place on February 3. As usual, six Tu-22M3 bombers took off in Russia and flew over Iran and Iraq. Air cover was provided by Su-30S and Su-35SM jet fighters from Russia's Hmeymim airbase in Province Latakia.
Daesh terrorists had surrounded the Deir ez-Zor military airfield in Syria's northeast by mid-January.
The city of Deir ez-Zor, which is still held by Syrian government forces, has been under siege from Daesh since July 2014. The residents of Deir ez-Zor and the servicemen only receive food and humanitarian aid via air-drops. On January 30, the United Nations resumed aid deliveries after a two-week pause.
Russia has been conducting a counter-terrorist campaign in Syria since September 30, 2015, at President Bashar Assad's request.
