As the war against ISIS rages in Syria and Iraq, Egypt is fighting its own war on terror. On October 24, the Sinai Peninsula witnessed the deadliest attack on Egypt’s military in years. Twenty-eight soldiers were killed and another 30 injured when a car bomb exploded at the Karm al-Qawadis security checkpoint in Sheikh Zuweid in North Sinai. Hours later, three security personnel were killed when militants opened fire at a checkpoint in nearby El Arish. Following the attack, Egyptian President Abdul-Fattah el-Sisi declared on state television that "foreign hands” were behind the violence,” and government sources have indicated that violence in Egypt—including Sinai—is linked to ISIS.
