The same source reports that several soldiers of the Marine Corps were fighting to the point of landing of Russian pilots in the north of Syria.
From the report:
Several groups of Syrian special forces, having entered into a direct clash with the Mujahideen, covered the rescue team simultaneously from three sides.
The day before there was information that fighters from the Hezbollah unit participated in the special operation. Officials have not yet confirmed this information.
Recall that in the course of the rescue operation, a Russian marine died, who was later awarded the Order of Courage posthumously.
