BEIRUT (Reuters) - 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.
The clashes came two weeks into a cessation of hostilities in Syria and on the eve of peace talks in Geneva between President Bashar al-Assad’s government and the opposition.
The halt in fighting, agreed by government forces, rebel groups and their international backers, excludes Nusra Front and Islamic State militants.
Nusra Front fighters have often taken part in offensives alongside other rebel groups. But they have also fought them for territory, defeating groups such as the Western-backed Syria Revolutionaries Front and the Hazzm group last year.
