On August 17, 2016, Russian bombers Su-34 took off from Hamedan airbase (Islamic Republic of Iran) with full fragmentation bomb charge and made an airstrike on ISIS terrorist facilities in the Deir ez-Zor province.
As a result, 2 command centres and large ISIS field training camps near the Deir ez-Zor city were destroyed, over 150 militants (with foreign mercenaries among them) were eliminated.
Su-35S, which had taken off from the Hmeymim airbase, covered the long-range bombers.
All Russian aircraft have returned to the airfield after accomplishing the combat task.
