It appears that the rebel Hawar Killis Operations Room has begun its assault on the Islamic State-held north Aleppo border town of al-Ra'i. Coalition air strikes, as well as Turkish artillery bombardment, were reported targeting IS positions in the area, throughout the day of 5 April. The rebel forces involved include both FSA groups, such as the likely-U.S. supported Liwa al-Moutasem, and independent factions, such as Faylaq al-Sham.
