Islamic State launched an attack on loyalist forces in southern Aleppo, on 15 April, taking around a dozen villages. This assault occurs while the government and its allies are fighting rebel forces on multiple fronts in Aleppo. This IS attack threatens the supply road, running through the town of Khanaser, that connects Aleppo to the rest of government-held territory. A similar IS attack on the road occurred over a month ago, and took weeks to fully defeat. Islamic State media sources have shown off a wide array of Iranian-made weapons and ammunition plundered, as well as the personal effects of Iranian combatants. IS also publicized the taking of an Iraqi Shia prisoner, from the Harakat al-Nujaba militia.
