Syria has been in a state of civil war since 2011, with government forces fighting Syrian opposition groups striving to overthrow the president. Damascus is also fighting numerous extremist and terrorist groups such as the Jabhat Fatah al Sham and Daesh, both outlawed in Russia. According to the United Nations, at least 300,000 Syrians have died since the beginning of the conflict.
