Explosives near Gracie Mansion
Two young men were arrested after improvised explosive devices were thrown near Gracie Mansion during dueling demonstrations outside New York Mayor Zohran Mamdani’s residence.
“New York police authorities arrested two young men after confirming they threw a homemade explosive device in front of Mayor Zohran Kwame Mamdani's official residence”
Fox News reported that "Two people remain in custody after an 18-year-old allegedly ignited and threw an improvised explosive device toward a protest Saturday during dueling demonstrations near East End Avenue and East 87th Street, steps from Gracie Mansion."

La Vanguardia said federal prosecutors charged "two 19-year-old men, Emir Balat and Ibrahim Kayumi of Pennsylvania, with using weapons of mass destruction after a homemade bomb was thrown near Gracie Mansion — New York’s mayor Zohran Mamdani’s residence — during an anti-Islam rally and a counterprotest."
UCV Radio likewise noted "Two teenagers — 19-year-old Ibrahim Qayoumi and 18-year-old Emir Balat — were arrested after deploying homemade bombs during an anti-Muslim protest in front of New York Mayor Zohran Mamdani’s residence at Gracie Mansion."
The reports contain contradictions over ages, name spellings, and charges: Fox described an 18-year-old allegedly igniting and throwing an improvised explosive device, La Vanguardia said two 19-year-olds (Emir Balat and Ibrahim Kayumi) were charged with using weapons of mass destruction, and UCV Radio named 19-year-old Ibrahim Qayoumi and 18-year-old Emir Balat as those arrested for deploying homemade bombs.
POLITICO reported that Mamdani said Muslim bigotry is familiar to him and to New York’s roughly one million Muslim residents, called a recent protest appalling, but defended the right to peaceful protest as sacred.
Explosive device reports
Officials and investigators described the devices as potentially lethal and linked the attack to extremist rhetoric.
Fox News said "Bomb-squad X-rays showed jars wrapped in black tape containing nuts, bolts and screws and a hobby fuse."
La Vanguardia reported that "NYPD Commissioner Jessicca Tisch said the act was 'inspired by the Islamic State,' and police said the suspects referenced IS and (according to authorities) spoke of intending 'a massacre larger than the Boston Marathon.'"
UCV Radio provided forensic detail that "Federal sources and officials said the devices contained TATP (the volatile explosive nicknamed the 'Mother of Satan'), packed in a bottle or jar with nuts, bolts and a fuse, and would have been lethal if fully detonated."
Fox News also reported an eyewitness detail that one suspect "shouted 'Allahu Akbar' before throwing the device."
Arrests and FBI searches
Authorities say the suspects were detained at the scene and that federal investigators have executed wider searches in connection with the case.
“New York City officials confirmed Sunday that two devices recovered during protests near Gracie Mansion a day earlier were improvised explosive devices (IEDs)”
La Vanguardia wrote that "The two arrived by car, were arrested at the scene and arraigned in court in shackles."
Fox News named the suspects and their immediate capture: "both suspects, identified as Balat and Kayumi, were arrested."
UCV Radio said probes expanded to Philadelphia suburbs: "Investigators say both teens made pro-ISIS statements in custody, admitted watching extremist propaganda, and had recent travel to the Middle East (including trips to Turkey and Saudi Arabia); their travel histories and possible ties to training camps are under review."
UCV Radio added that FBI teams executed search warrants and raided homes in affluent Philadelphia suburbs (Newtown and Langhorne), detaining several people and seizing evidence.
POLITICO noted the legal process and response by defence counsel: "An attorney for Kayumi did not immediately respond."
Rally and harassment reports
The incident unfolded amid a small far-right rally and a larger counterprotest.
Sources differ on the rally organiser: La Vanguardia reported the rally had been organized by far-right influencer Jake Lang under the slogan 'Stop the Islamic takeover of New York', while UCV Radio described the event similarly but spelled the name as Jake Long and called him an 'extremist influencer'.
Fox News noted the scene's wider disruption and arrests, reporting that 'three others were also arrested on charges including disorderly conduct and obstructing traffic'.
POLITICO placed the attack in the wider context of sustained harassment and Islamophobic attacks against Mamdani, saying that during the campaign 'a Cuomo team ad showing Mamdani eating rice with his hands was widely condemned as Islamophobic and pulled'.
POLITICO also reported that 'Council Member Vickie Paladino is facing discipline after suggesting Muslims should be deported and claiming a Mamdani staffer born in Brooklyn 'was not American' because she is Muslim'.
Federal probe and responses
Federal authorities have taken the matter into their hands, prosecutors have signalled serious charges, and Mayor Mamdani vowed to protect residents.
“Skip to Main Content A bomb thrown outside Gracie Mansion unearths grim reality for NYC mayor A potent mix of political, religious and ideological strife is likely to haunt Zohran Mamdani’s time in office”
Fox News said the NYPD is working with the U.S. Attorney’s Office for the Southern District of New York and the FBI’s Joint Terrorism Task Force.

La Vanguardia reported that the suspects were charged with using weapons of mass destruction.
UCV Radio summarized the criminal probe’s trajectory, saying a federal terrorism investigation is underway and prosecutors expect an indictment to be unsealed soon.
La Vanguardia recorded Mayor Mamdani condemning the attack and vowing to hold the suspects accountable and keep New Yorkers safe.
