A suspected ISIS-inspired militant alleged to have tried to set off an explosive device at Gracie Mansion has defiantly flashed an ISIS salute as he was led away in shackles during his perp walk. Wearing a black t-shirt and beige pants, Balat made the gesture before one of the officers detaining him slapped his hand down. Balat, whose parents are reportedly from Turkey but who became naturalized citizens in 2017, was arrested Saturday along with 19-year-old Ibrahim Kayumi after a homemade "Mother of Satan" bomb was allegedly thrown at protesters outside New York Mayor Zohran Mamdani's Upper East Side residence.
