Following the announcement, media reports emerged claiming that Aleppo would also be involved in the regime, but were refuted by a different source.

The ceasefire in Syria, worked out by Russia and the United States, took effect on February 27. Terrorist groups are not part of the agreement; Sputnik reported.
