The Islamic State (formerly ISIS) killed Jaysh al Islam fighters in a car bombing in Ghouta, executed seven Jaysh al Islam fighters in Mid’a, and arrested 25 more. The IS also arrested three people in Raqqah for not fasting; clashed with Kurdish YPG fighters at a checkpoint in Hasakah; bombarded villages near Ektrin and fought against Al Nusrah, the Islamic Front, Al Akrad Front Brigade, and rebels in Aleppo; and clashed with the Al Nusrah Front and the Islamic Front in Albu Kamal in Deir Izzour after bringing in reinforcements from Iraq through al Qaim. The IS also battled Al Nusrah and the Islamic Front near Al Shhil in Deir Izzour, a town considered an Al Nusrah headquarters. Regime forces attacked Al Nusrah in Deraa; and in Aleppo, where Al Nusrah was joined by the Islamic Front and the Jaysh al Mujahideen. The Islamic Front also clashed with regime forces in Deraa; Damascus; and Hama, where it downed a regime aircraft, and the house of an ex-governor of Deraa was blown up by unknown gunmen. In Idlib, the Islamist group Jund al Aqsa launched mortars into regime-held areas of Idlib city, killing at least 15 people, including women and children, and wounding 50, and warned “ordinary Muslims” to stay away from gatherings of regime forces.
