Syria's main rebel group says it is moving its command centre from the Turkish border into Syria itself in preparation of an offensive against President Bashar al-Assad's troops in Damascus. Riyad al-Asaad, commander of the Free Syrian Army (FSA), announced the move on Saturday in a video message from Syria, the first since the group founded its command centre in Turkey at the beginning of the 19-month conflict. Al Jazeera's Hashem Ahelbarra and Andrew Simmons report.
