The leaders of the rebel Free Syrian Army say they have moved their command center from Turkey to Syria, according to The Associated Press.

Brig. Gen. Mustafa al-Sheikh, who heads the FSA's Military Council, told AP that the move aims to unite all rebel groups. He said Saturday that the move was made the week before, without specifying its new location.

FSA commander Col. Riad al-Asaad issued a video titled "Free Syrian Army Communique Number 1 from Inside" that the command has moved to "liberated areas."

The FSA has been the most prominent of the rebel groups trying to remove President Bashar Assad from power. But its commanders have come under criticism in the past for leading from Turkey, and its authority over numerous locally-based networks of fighters is limited.
