A device found outside of Gracie Mansion on Saturday during dueling protests in New York City was confirmed to be an improvised explosive device, according to police.

Two men were taken into custody after at least one of two devices was ignited during an anti-Islam demonstration led by conservative influencer Jake Lang and a counterprotest outside the mansion, which serves as a residence for New York City's mayor. It was unclear at the time what the devices were and whether they were a danger to the public.

New York City Mayor Zohran Mamdani, who is Muslim, was inside the residence at the time of the incident.
