"Today I can say that the Syrian Arab Army with the support of its friends and allies was able to suppress this aggressive war and regain the initiative," the military official said.
Damascus has successfully taken back control of most Syrian cities, while the militants are currently being besieged in separate territories and engulfed in internal strife, Khaddur said.
"For over six years Syria has been in a severe terrorist war due to its geostrategic location … This war is led by the terrorist groups, which receive all kinds of military and political support from a very large number of regimes within the region and around the world," the official added.
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 the Islamic State, both outlawed in Russia.
