Al Qaeda in Syria seizes bases, weapons of Western-backed group: monitor
The al Qaeda-linked Nusra Front seized bases and weapons from a Western-backed rebel group in overnight fighting in northwestern Syria, the Syrian Observatory for Human Rights said on Sunday.
Rami Abdulrahman, director of the Observatory, said the Nusra Front had also detained dozens of members of the 13th Division rebel group, one of the factions that has received foreign military aid, capturing U.S.-made anti-tank missiles.
The 13th Division, which is led by the prominent rebel commander Ahmed al-Seoud and fights under the banner of the Free Syrian Army, said on Twitter that Nusra Front fighters attacked its bases and seized weapons, but gave no further details.
Nusra Front accused the rebel fighters of launching surprise attacks on its own bases in the town of Maarat al-Numan in Idlib province in northwest Syria. It said some Nusra fighters had been captured.
