BUCKS COUNTY, Pa. — The two Pennsylvania teenagers accused of planning an ISIS-inspired terror attack in New York City were previously unknown to each other, according to the defense attorney representing one of the suspects.

Ibrahim Kayumi, aged 19, from Newtown, and Emir Balat, aged 18, allegedly traveled from Bucks County to Manhattan, where they reportedly hurled live explosive devices into a protest outside Mayor Zohran Mamdani’s Gracie Mansion residence on Saturday, federal authorities have stated.

Mehdi Essmidi, the lawyer for Balat, told reporters that the two young men had not met before the alleged incident.

“As far as I’m aware, they were strangers,” Essmidi remarked. “They hail from different regions of Pennsylvania, belong to separate age groups, and have no known connections. They do not reside together, nor do they share family or educational ties.”

Balat, who is still in high school, has been completing his coursework remotely, his attorney revealed to the media.

Though Balat is in high school, his attorney told reporters that he was finishing classes remotely.

“He’s 18, he’s finishing school remotely because he has only like three classes left to do. He’s in his senior year,” Essmidi said.

A district spokesperson told Fox News Digital that Balat is currently in 12th grade in the Neshaminy School District. Kayumi graduated in 2024 from Council Rock High School North, school officials confirmed.

Prosecutors said in a complaint that a series of pictures show the men handling the alleged bomb, which was later determined to have contained TATP and had nuts and bolts attached with duct tape.

NYPD Commissioner Jessica Tisch said Monday that the devices were real and capable of causing serious injury or death.

“This is being investigated as an act of ISIS-inspired terrorism,” Tisch said.

While at a precinct station after being arrested, Balat allegedly wrote and signed a pledge of allegiance to the Islamic State, according to federal prosecutors.

“All praise is due to Allah lord of all worlds! I pledge my allegiance to the Islamic State,” Balat allegedly wrote. “We take action.”

Balat allegedly told law enforcement that he and Kayumi wanted to go through with an attack “bigger than the Boston Marathon bombing.”
