Islamic State-inspired attack: Teens charged over NYC protest bombs

Published: 10 March 2026. The English Chronicle Desk. The English Chronicle Online.

A dramatic security incident unfolded in New York after an alleged Islamic State-inspired attack near the mayor’s residence raised serious concerns. Two teenagers now face federal terrorism charges after authorities say they threw explosive devices outside the home of Mayor Zohran Mamdani during a tense weekend protest.

The alleged Islamic State-inspired attack occurred on Saturday near Gracie Mansion, the official residence of New York’s mayor. The protest gathered activists opposed to Islam alongside counter-demonstrators defending religious tolerance. Although tensions ran high, the situation escalated further when explosive devices were thrown toward protesters.

Federal prosecutors later confirmed that both suspects were charged with several terrorism-related offences in connection with the Islamic State-inspired attack. Authorities identified the suspects as 18-year-old Emir Balat and 19-year-old Ibrahim Kayumi, who travelled from Pennsylvania to New York before the incident.

According to a criminal complaint filed in federal court in Manhattan, the pair allegedly declared allegiance to the militant group Islamic State. Investigators said their actions appeared motivated by extremist propaganda and a desire to carry out a violent attack.

The complaint states that Balat allegedly threw the explosive devices after receiving them from Kayumi during the demonstration. Witnesses said the objects were ignited before being thrown toward a crowd gathered near the protest.

Fortunately, neither device detonated, preventing what officials warned could have been devastating consequences. Bomb disposal specialists from the New York Police Department quickly secured the area and safely neutralised both devices.

The explosive materials used in the alleged Islamic State-inspired attack included triacetone triperoxide, commonly known as TATP. This unstable compound is often described by investigators as extremely dangerous because it can detonate with little warning.

Jessica Tisch, the New York police commissioner, addressed reporters shortly after the arrests during a press conference in Manhattan. She explained that the devices were genuine explosive mechanisms and not harmless items designed to scare people.

“These were not hoax devices, nor smoke bombs,” Tisch said during the briefing. She emphasised that such devices could have caused serious injury or even fatalities among protesters and police officers nearby.

Authorities arrested the suspects less than one hour after they arrived in New York from Pennsylvania. Police said the rapid response by officers prevented the situation from escalating further.

Investigators from the Federal Bureau of Investigation later joined the inquiry through the Joint Terrorism Task Force. Officials described the case as a possible act of terrorism influenced by extremist ideology.

According to the court complaint, Balat allegedly ignited and threw the first explosive device around midday. After throwing the first device, he reportedly ran down the street to collect another item from Kayumi.

The complaint explains that Balat attempted to ignite a second device before dropping it near several police officers. Officers immediately chased the suspect, tackling him after he attempted to escape by jumping over a barricade.

Federal investigators said both teenagers later admitted their involvement during questioning by authorities. Balat allegedly pledged allegiance to Islamic State, while Kayumi reportedly said his actions were partly inspired by the group.

Court documents also revealed a chilling claim allegedly made by Balat during questioning by investigators. Prosecutors said he told agents that he wanted the attack to be even larger than the 2013 Boston Marathon bombing.

That notorious attack killed three people and injured hundreds more in one of America’s deadliest modern terrorist incidents. Authorities said such remarks reinforced concerns about extremist motivations behind the alleged plot.

Mayor Zohran Mamdani spoke publicly after the arrests, condemning the attempted violence in strong terms. He said the suspects travelled deliberately to New York intending to bring harm to residents and demonstrators.

The mayor also praised two police officers whose quick reaction led to the suspects’ immediate arrest. Their actions ensured that the explosive devices were removed safely without causing injuries.

Mamdani emphasised that New York must remain committed to protecting both safety and freedom of expression. He acknowledged the protest itself contained inflammatory rhetoric but defended the principle of peaceful demonstration.

The mayor noted that anti-Muslim hostility remains a persistent challenge for many communities across the city. He said Muslim residents in particular have experienced prejudice and discrimination for many years.

Despite these difficulties, Mamdani insisted that protecting civil liberties remains essential within a diverse democratic society. He argued that even controversial protests must be allowed, provided they remain peaceful and lawful.

Saturday’s demonstration had been organised by far-right activist Jake Lang under the banner “Stop the Islamic Takeover of New York City.” Around twenty supporters attended, while dozens of counter-protesters gathered nearby.

Reports from local media described several confrontations between opposing groups during the protest. Some participants threw eggs, while others shouted slogans and exchanged heated arguments throughout the afternoon.

Police confirmed that at least six people were arrested during the wider protest for various offences. One supporter of the demonstration was also accused of using pepper spray against a counter-protester.

Authorities stressed that the alleged Islamic State-inspired attack appeared unrelated to tensions between the rival protest groups. Investigators believe the suspects acted independently rather than as part of the demonstration itself.

Commissioner Tisch explained that New York police were already maintaining heightened security levels before the incident. Global tensions had recently increased following military strikes involving the United States and Israel in Iran.

Despite those international developments, investigators said they found no direct connection between the case and overseas events. Officials emphasised that the investigation remains ongoing and could still reveal additional details.

Police also discovered another suspicious device inside a car linked to the suspects near the protest area. The object was removed by a bomb disposal robot and later tested by investigators.

Fortunately, tests showed the item did not contain explosive material similar to the earlier devices. Authorities nevertheless treated the discovery seriously during the continuing terrorism investigation.

Commissioner Tisch said investigators are still examining the suspects’ movements before arriving in New York. She confirmed that officials are aware the pair recently travelled internationally but declined to provide further details.

So far, neither suspect had previous arrests or significant encounters with law enforcement authorities. Investigators also found no online threats indicating they planned the attack before travelling to New York.

The explosive devices recovered during the incident have been sent to an FBI laboratory for detailed analysis. Specialists will examine their construction and chemical components to understand how they were assembled.

Experts say TATP explosives are extremely unstable and can detonate accidentally during handling or transport. Because of this danger, the substance has frequently appeared in several terrorist attacks worldwide.

New York has experienced few explosive incidents in recent years compared with earlier decades. Officials noted that the last improvised explosive attack occurred in 2017 inside the Manhattan subway system.

That attack injured four people but fortunately caused no fatalities thanks to a malfunctioning explosive device. Authorities say the recent incident demonstrates the continuing importance of vigilance and strong counter-terrorism efforts.

Commissioner Tisch concluded her remarks by acknowledging that the city avoided tragedy largely through swift intervention. She warned that such devices remain capable of causing devastating harm if they successfully detonate.

Security officials now hope the arrests will reassure residents while investigators continue their work. The case highlights how extremist ideology can influence individuals far from traditional conflict zones.

As the legal process begins, prosecutors must prove that the suspects deliberately attempted a terrorist attack. The charges carry severe penalties under federal law, reflecting the seriousness of alleged terrorism offences.

New York authorities insist they will remain vigilant against any threats targeting residents or public gatherings. The incident has already renewed debate about online radicalisation and the spread of extremist propaganda.

For many observers, the alleged Islamic State-inspired attack represents another reminder of the evolving nature of modern terrorism. Even small plots can create fear and disruption within busy urban communities.

City officials hope the swift response will reinforce public confidence in New York’s security services. Their actions ensured that a potentially deadly situation ended without injury or loss of life.
