Russian strategic bombers destroyed several terrorist camps, training centers and a command post of one of the major terrorists' units near Daesh's de facto capital of Raqqa.
The ministry said that "reconnaissance means have confirmed the destruction of all designated [terrorist] targets" near Raqqa.
The long-range bombers that took off from a Russian airfield flew over Iraq and Iran. After launching cruise missile strikes on Daesh targets, the bombers returned to Russia.
"Su-30SM and Su-35S provided air cover to the Russian bombers from the Hmeymim airbase."
Meanwhile, the Pentagon said that Russian and US-led coalition's militaries used mechanism on safety of flights over Syria to avoid any incidents near Raqqa, where the coalition is also conducting airstrikes.
De-confliction of air ops w/Russia continue. Today they conducted ops in vicinity of #Raqqah. So did @CJTF-OIR.
