Tisch identified the suspects as Emir Balat, 18, and Ibrahim Kayumi, 19, both from Pennsylvania, and law enforcement described the devices as capable of causing serious injury or death.

Protest context and clash

The explosives were thrown amid an anti-Muslim protest called by far-right activist Jake Lang and a larger counter-protest.

Reporters and officials described a clash in which the initially small right-wing rally of about 20 people faced roughly 125 counter-protesters under the slogan "Expel the Nazis from New York," and tensions escalated until devices were thrown into the roadway and people and police fled the area.

Suspects' statements and charges

Investigators reported statements from the defendants that include Balat allegedly writing he had "pledged allegiance to the Islamic state" and Kayumi telling police he watched ISIS material and considered himself "affiliated" with ISIS; officials have not said whether the pair were directly recruited or self-radicalized.

Device details and disposal

Officials described the devices in technical detail: at least one device contained explosive material and shrapnel and was intended to cause serious injury or death, and investigators said at least one device was made with triacetone triperoxide (TATP), a volatile compound often used in IEDs.

Law enforcement also located a third device that did not contain explosive material and authorities disposed of it after identifying it in a nearby vehicle.

Charges and official response

Federal prosecutors have charged Balat and Kayumi with providing material support to ISIS and with using a weapon of mass destruction, and U.S. Attorney Jay Clayton and other officials framed the case as an example of "ISIS-inspired actions" that will be met with swift justice.
