The armed conflict in Syria has been ongoing since 2011. Operations against militants continue in some areas in Syria, but the focus has largely shifted toward political settlement.
Russia, along with Turkey and Iran, is a guarantor of the ceasefire regime in Syria. Moscow has also been providing humanitarian aid to residents of the crisis-torn country.
