Syria has been in a state of a civil war since 2011, with the government forces fighting against numerous opposition groups as well as militant and terrorist organisations. Along with Turkey and Iran, Russia acts as a guarantor of the ceasefire in the Arab republic. Moscow has also been providing humanitarian aid to residents of the crisis-torn country.
