Linked to ISIS-Inspired Terrorism Near NYC Mayor’s Home
Federal agents uncovered explosive residue in a Bucks County, Pennsylvania storage unit connected to an ISIS-inspired terrorism incident outside New York City, Mayor Zohran Mamdani’s residence. NYPD arrested two Pennsylvania teenagers on-site in NYC on March 7, 2026, following the attack near Gracie Mansion. The FBI conducted a court-authorized search of the storage unit on March 9, after which local authorities performed controlled detonations of hazardous materials on Monday due to safety risks.
Incident Details
On Saturday, March 7, 2026, between 11 a.m. and 12:30 p.m., improvised explosive devices (IEDs) were thrown during protests near Gracie Mansion, the mayor’s official home in Manhattan. NYPD Commissioner Jessica Tisch confirmed the devices were real IEDs designed to injure or kill, not mere smoke bombs or hoaxes. Video footage captured 18-year-old Emir Balat yelling “Allahu Akbar” as he threw one device amid an anti-Islam demonstration; a second was dropped nearby.
No devices detonated fully, and no injuries occurred. A third suspicious device recovered from the suspects’ vehicle on East End Avenue tested negative for explosives. License plate readers tracked their suspect vehicle crossing the George Washington Bridge less than an hour before the first IED was thrown. Investigators recovered a notebook from the vehicle listing chemicals for triacetone triperoxide (TATP), hydrogen peroxide, sulfuric acid, acetone, plus aluminum cans and bolts used in bomb-making.
Suspect Profiles and Charges
The suspects are 19-year-old Ibrahim Kayumi from Newtown, Pennsylvania, and 18-year-old Emir Balat from Langhorne, Bucks County. Both face federal charges in the Southern District of New York, including unlawful possession and use of a “weapon of mass destruction,” transporting explosives across state lines, and attempting to aid ISIS, a designated foreign terrorist organization.
After waiving Miranda rights, Kayumi told police “ISIS” when asked about his motives and admitted viewing ISIS propaganda. Balat wrote a pledge of allegiance to the Islamic State. Prosecutors say the pair aimed to exceed the 2013 Boston Marathon bombing’s death toll of three and injuries to over 260. Kayumi’s mother had reported him missing that morning. As of March 10, both remain detained pending bail hearings.
FBI Storage Unit Search
The FBI’s March 9 raid targeted a Public Storage facility in Middletown Township, Bucks County, Pennsylvania, tied to the suspects. Agents found explosive residue and components, which local authorities detonated in at least three blasts late Monday for safety. A high-ranking law enforcement source described extracting various chemicals and materials. Investigators are probing the January explosion reports in a nearby Pennsylvania town where one suspect lived.
U.S. Attorney Jay Clayton and Deputy Attorney General Todd Blanche emphasized the plot’s severity, noting the suspects’ post-arrest ISIS admissions. The Joint Terrorism Task Force, including the NYPD and FBI, leads the probe.
Investigation
NYPD and federal partners confirmed there are no links to overseas conflicts, such as those involving Iran. Mayor Mamdani, the city’s first Muslim mayor, was visiting a Brooklyn museum with his wife, Rama Duwaji, and family during the attack; he called it a “vile protest” tied to white supremacy. Tisch labeled it “ISIS-inspired terrorism” from the outset.
Additional evidence includes a hobby fuse and an empty metal can from the suspects’ vehicle. Preliminary tests on one IED detected a highly explosive material used in recent terror attacks. The case unfolds amid heightened U.S. vigilance on domestic extremism.
