NEWARK, N.J. (AP) — A 20-year-old New Jersey man has admitted conspiring to provide material support to the Islamic State group by planning to travel to Syria and join them. Nader Saadeh of Rutherford pleaded guilty Thursday in U.S. District Court. He remains detained without bail. Saadeh is the last of three New Jersey defendants to admit guilt in the case, which came to light in August when he was arrested by the FBI. He acknowledged a co-defendant showed him diagrams for making homemade bombs and discussed plans to use them in Times Square, the World Trade Center and Vaughn College of Aeronautics and Technology, in Queens, New York. He faces 15 years in prison when he is sentenced March 18.
