Self-radicalized ISIS protesters used explosive called ‘Mother of Satan’ inside bombs thrown at Gracie Mansion protest – sources | 10 March 2026 | A pair of ISIS[I-CIA-SIS]-trained extremists were charged with hurling an IED at Gracie Mansion duringa rowdy weekend protest — allegedly packing the homemade bomb with “Mother of Satan,” a volatile explosive favored by international terrorists. The two pro-Muslim men — Ibraham Kayumi, 19, and Emir Balat, 18 — both self-radicalized in recent years and traveled to Turkey and other terror-training hot spots, law enforcement sources close to the case told The Post. The pair admitted to cops after getting busted at the violent demonstration outside the mayor’s residence on Saturday afternoon that they also watched ISIS videos and tossed the bomb at right-wing agitators because they felt the agitators insulted their religion, the sources said.
