UPDATE 3:40 P.M. EST

The criminal complaint unsealed in a Brooklyn federal court has revealed more of the plans and ideas of the three men arrested Wednesday for allegedly trying to join ISIS. One plan, which would have been launched Wednesday, was to hijack a commercial flight to Turkey and deliver the plane to the Islamic State militant group in Iraq and Syria. Other ideas included joining the U.S. military so they could then attack soldiers, and potentially killing American law enforcement officers, CNN reported.

The men had published some of their plans online, according to the court complaint. Previous media reports had said that the three men were arrested in New York, but in fact two were arrested in New York and one in Florida, according to the New York Times. Two of the men, Juraboev and Saidakhmetov, were permanent residents of the U.S. and citizens of Uzbekistan, while the third, Habibov, was an Uzbek citizen.

UPDATE 1:46 P.M. EST

The suspects arrested in New York on Wednesday have been identified as Abdurasul Jaraboev, 24, Akhror Saidakhmetov, 19, and Abror Habibov, 30. Jaraboev allegedly wrote online about shooting President Barack Obama, while Saidakhmetov had said in a recorded conversation that if he was unable to reach Syria he would "just go out and buy a machine gun, AK-47, go out and shoot all police," according to papers released in a Brooklyn federal court.

ORIGINAL STORY

Three people in New York City have been arrested for allegedly trying to join ISIS, the Islamic State militant group. The FBI and the Joint Terrorism Task Force arrested three Brooklyn men, one of them at John F. Kennedy International Airport before he was able to fly to Turkey.

Had they failed to join ISIS, the men planned to carry out attacks in the U.S., said the FBI, according to Pix 11. The two other men were arrested elsewhere, in Brooklyn, according to NBC. The ages of the men were 19, 24 and 30, and they were discovered in part because of postings online.

The men have been charged with conspiracy to provide material support to a terror group.
