Two men charged with terror offences after homemade bomb thrown outside NYC mayor's home

March 10, 2026

Two teenagers, 18-year-old Emir Balat and 19-year-old Ibrahim Kayumi, face terrorism charges after authorities say they tried to detonate homemade explosives at a protest near New York City's Gracie Mansion, where Mayor Zohran Mamdani resides. Police report the suspects admitted to being motivated by Islamic State propaganda and told investigators they wanted their attack to surpass the 2013 Boston Marathon bombing in casualties. The improvised explosive devices, made from glass bottles containing the volatile compound triacetone triperoxide and packed with shrapnel, failed to detonate as planned during the incident that occurred at dueling protests.

Who is affected

  • The two suspects: Emir Balat (18) and Ibrahim Kayumi (19)
  • Mayor Zohran Mamdani
  • Protesters and counter-protesters at the scene (over 100 counter-protesters mentioned)
  • New York City residents
  • Two police officers who responded to the lit devices
  • Ian McGuiness (21) and three others charged with disorderly conduct
  • The suspects' legal representatives

What action is being taken

  • The NYPD is maintaining heightened counter-terrorism vigilance
  • The FBI Joint Terrorism Task Force is conducting interviews, reviewing videos, collecting evidence, and pursuing all leads
  • The two suspects are being detained pending their next court appearance on April 8

Why it matters

  • This incident represents a domestic terrorism threat inspired by international terrorist propaganda, demonstrating that IS continues to radicalize individuals within the United States despite having no organizational connection. The explosives used the same volatile compound employed in other major terror attacks and contained shrapnel designed to maximize casualties, meaning successful detonation could have resulted in mass casualties at a public gathering. The attempt occurred during a period of heightened security concerns related to international conflicts, underscoring ongoing vulnerabilities to lone-wolf attacks in major American cities.

What's next

  • The suspects have a next court appearance scheduled for April 8
  • The FBI Joint Terrorism Task Force will continue conducting interviews, reviewing videos, collecting evidence, and chasing down all leads
