Syria has been mired in civil war since 2011, with government forces loyal to President Bashar Assad fighting numerous opposition factions and extremist groups, including Daesh and Nusra Front, a Syrian division of al Qaeda that has changed its name to Jabhat Fatah al Sham, which are outlawed in many countries including Russia.
