The protesters busted for hurling an IED at Gracie Mansion trained with ISIS overseas and packed their bomb with “Mother of Satan” – an explosive long favored by international terrorists, sources said.
The two pro-Muslim fanatics – Ibraham Kayumi, 19, and Emir Balat, 18 – both self-radicalized in recent years and traveled to Turkey and other terror-training hot spots, law enforcement sources close to the case told The Post.
Balat spent more than three months in Istanbul last year, while Ibrahim flew to Istanbul and Saudi Arabia in 2024, and made a trip to Melbourne, Australia in 2019, they said.
Both admitted to cops after getting busted at a rowdy demonstration outside the mayor’s residence on Saturday that they also watch ISIS videos and tossed the bomb at right-wing agitators because they felt they insulted their religion, the sources said.
The homemade device consisted of sports drink bottles filled with triacetone triperoxide, or TATP, a substance favored by terrorists and known as “Mother of Satan” — which is so volatile that it typically doesn’t require a fuse to go off, they said.
The same type of bomb was used in high-profile terror attacks in France and the UK over more than a decade.
