The FBI raided the upscale homes of two ISIS-inspired extremists accused of hurling bombs during the weekend’s protest near Gracie Mansion, including a $2.25 million six-bedroom mansion in a leafy Pennsylvania suburb.

The FBI’s Evidence Response Team searched the Bucks County homes of Ibraham Kayumi, 19, and Emir Balat, 18, on Sunday after the radicals were busted for allegedly throwing homemade IEDs during a violent clash between right-wing agitators backing Jake Lang and pro-Muslim counter-protesters Saturday afternoon.

Armed agents on Sunday were filmed storming Kayumi’s house in Newtown, Penn., close to the border with New Jersey.

The lavish six-bed, five-bath home, built in 2018, has an estimated value of $2.25 million and is around 5,800 square feet, according to property records

It isn’t known if the property is owned or rented by Kayumi’s parents, who immigrated to the US from Afghanistan and were naturalized in the 2000s, sources told Fox News.

Photos also showed agents hauling evidence, including what looked like computer parts, from Balat’s home in Langhorne, Penn., a couple of miles south of Newtown in the Philadelphia suburbs.

The four-bed, two-bath, 3,200 square-foot house, built in 1991, is estimated to be worth around $653,000.

Balat’s parents are Turkish nationals who became naturalized citizens in 2017, according to the Fox News report.

“FBI New York continues to be engaged with NYPD and all of our law enforcement partners actively investigating the two devices thrown outside Gracie Mansion yesterday afternoon,” the feds said on X Sunday night.

“The FBI and NYPD confirmed the suspicious items to be improvised explosive devices (IEDs). Additionally, the FBI Joint Terrorism Task Force (JTTF) will be conducting interviews, reviewing videos, collecting evidence, and chasing down all leads.”

The makeshift bombs — a sports drink bottle stuffed with TATP and wrapped in construction tape — were lobbed at Lang’s crew as the rival demonstrators squared off near Mayor Zohran Mamdani’s Big Apple residence during a planned anti-Muslim rally organized by the “white supremacist.”

The deadly devices — packed with the terrorist-favored volatile explosive known as “Mother of Satan” — fortunately failed to detonate, after police swiftly secured the bombs, removed the lethal mix and ended the threat.

Video footage shows several heated scuffles that led to six arrests — including those of the two accused wannabe bombers.

Mamdani has come under fire for soft-pedaling the incident — and for not identifying who brought the bombs to the rally, while condemning Lang for organizing a rally “rooted in bigotry and racism.”

Local police leaders have called on him to declare the attack an act of terrorism.

“This was a clear cut terrorist attack,” the Sergeants Benevolent Association blasted on X Sunday, adding the rabblerousers are “testing” the mayor’s “resolve.”

“Whether you pass or fail this test depends on your resolve to protect this city. This was a terrorist attack by people who promote hate on both sides. We could have lost many cops and civilians yesterday. You should have already taken charge within the first hour not almost 24 hours later!”

Former governor Andrew Cuomo, who was soundly defeated by Mamdani in November, also took aim at the mayor over his handling of the attack.

“This was a terrorist attack, no slap on the wrist,” Cuomo told WABC Radio Sunday.

“Terrorism is a federal crime. Just let the federal government take it over, let them do the prosecution, and let them send a signal there is zero tolerance for terrorism. If you don’t do that, if you don’t do that in this moment, don’t be surprised what happens next. Thank God the bomb didn’t go off.”

TATP has been linked to high-profile terror attacks throughout the globe for more than a decade.

The botched explosive is so volatile that it typically doesn’t require a fuse to go off, sources said, adding the dangerous substance can be cobbled together using household items, making it cheap to produce.

“It’s designed to maim and kill,” one source told The Post.

“This is just luck no one is dead.”
