BEIRUT – The leaders of the rebel Free Syrian Army said Saturday they moved their command center from Turkey to Syria with the aim of uniting rebels and speeding up the fall of President Bashar Assad's regime.

Brig. Gen. Mustafa al-Sheikh, who heads the FSA's Military Council, told The Associated Press that the group made the move last week. He would not say where the new headquarters is located or give other details.

The FSA is the most prominent of the rebel groups trying to topple Assad, though its authority over networks of fighters in Syria is limited. Its commanders have been criticized for being based in Turkey while thousands are killed inside Syria.
