Federal terrorism counts filed after TATP devices thrown at rally outside mayor’s home
Federal Terrorism Charges Filed After Explosives Thrown Outside NYC Mayor’s Home
Two young men from Pennsylvania were charged on Monday, March 9, 2026, with federal terrorism offenses after they allegedly threw improvised explosive devices during a protest outside Gracie Mansion, the official residence of New York City Mayor Zohran Mamdani. The suspects — Emir Balat, 18, of Langhorne, Pennsylvania, and Ibrahim Kayumi, 19, of Newton, Pennsylvania — face a five-count federal complaint that includes attempting to provide material support to a designated foreign terrorist organization, use of a weapon of mass destruction, and transportation of explosive materials. Both were held without bail following their arraignment Monday morning. The FBI’s Joint Terrorism Task Force and the U.S. Attorney’s Office for the Southern District of New York are leading the prosecution.
What Happened on March 7
The incident unfolded on a Saturday afternoon, March 7, 2026, during a rally organized by Jake Lang — a pardoned January 6 rioter and far-right influencer — outside Gracie Mansion on the Upper East Side. Lang titled his event “Stop the Islamic Takeover of New York City.” More than 100 counter-protesters turned out under the banner “Run the Nazis Out of New York City: Stand Against Hate.” During the confrontation, a member of Lang’s group, 21-year-old Ian McGuiness of Philadelphia, allegedly pepper-sprayed counter-protesters and was arrested. Moments later, body-worn camera footage captured Balat lighting a homemade explosive device and throwing it toward the crowd. Witnesses described flames and smoke as it flew through the air before striking a barrier in a crosswalk near officers and extinguishing. Balat then allegedly retrieved a second device from Kayumi, lit it, and dropped it while fleeing on East End Avenue. Both men were quickly apprehended. The following day, a third suspicious device was discovered inside a vehicle three blocks from the mansion; the NYPD bomb squad removed it but it did not test positive for explosive material.
TATP: A Signature Terror Explosive
Testing by the NYPD bomb squad confirmed that at least one device contained triacetone triperoxide, known as TATP — a volatile homemade explosive linked to terror attacks around the world, including the 2005 London bombings and the 2016 Brussels attacks. NYPD Commissioner Jessica Tisch described the devices as sports drink bottles filled with explosive material, placed inside glass jars, wrapped in black tape and packed with metal fasteners. As Kayumi was placed into an NYPD vehicle after arrest, body-worn camera footage captured him telling a bystander who asked why he did it: “ISIS.” Balat later waived his Miranda rights and submitted a written statement declaring allegiance to the Islamic State. When officers asked Balat if he was inspired by the 2013 Boston Marathon bombing, he reportedly replied: “No, even bigger.”
The Federal Response
Mayor Mamdani and Commissioner Tisch appeared together Monday at a press conference outside Gracie Mansion. Mamdani said the two suspects “traveled from Pennsylvania and attempted to bring violence to New York City.” He praised Chief Aaron Edwards and Sgt. Luis Navarro for running toward the devices to protect bystanders. Attorney General Pam Bondi stated that authorities “will not allow ISIS’s poisonous, anti-American ideology to threaten this nation.” Tisch confirmed there is no evidence connecting the suspects to the ongoing Iran conflict, and that the investigation remains focused on their domestic radicalization through online ISIS propaganda.
A Dangerous Convergence
Security analysts noted that the Gracie Mansion episode reflects a particularly troubling convergence: an organized Islamophobic demonstration provided a stage for an ISIS-inspired attack. That dynamic — far-right hate organizing triggering radical Islamist violence — creates a security challenge that straddles domestic terrorism and foreign extremist influence. Mayor Mamdani, the city’s first Muslim mayor, has faced a pattern of Islamophobic harassment since his campaign. A conservative radio host called him a “radical Islam cockroach” on social media after the bomb incident before issuing a public apology. Mamdani’s office noted that he and his wife “face threats regularly.” PBS NewsHour’s full report on the charges provides additional detail. The U.S. Attorney’s Office SDNY is prosecuting the case. Civil rights organizations including CAIR called on federal officials to take Islamophobic organizing seriously alongside the ISIS-inspired attack. The Southern Poverty Law Center tracks Jake Lang and others connected to January 6 extremism. The outcome of the federal prosecution, and broader questions about online radicalization and the legal accountability of hate-rally organizers, will shape this story for months to come.
