A U.S. man has been arrested and charged with conspiring and attempting to join Islamic State militants.
The complaint, filed at the U.S. District Court in the eastern state of New Jersey, charges Nader Saadeh conspired with his brother, Alaa Saadeh, and others from New York and New Jersey to provide material support to the terror group.
The document says an informant tipped off the FBI and the Joint Terrorism Task Force in April about his increased radicalization and plans to join the Islamic State.
The complaint says Saadeh traveled to Amman, Jordan, in May and planned to continue to Islamic State strongholds in Iraq or Syria by way of Turkey, but was detained by Jordanian authorities.
Saadeh faces up to 40 years in prison and fines of up to $500,000 if convicted of the charges.
During the investigation, the FBI obtained computer files showing that Saadeh viewed IS propaganda videos and researched flights to Turkey. The FBI also obtained messages sent by his mother and other family member pleading with him not to join the militant group.
Alaa Saadeh, was arrested on June 29 and faces charges of conspiring to support Islamic State and witness tampering.
