The unidentified suspect is believed to be affiliated with the Islamic State militant group, according to Iraq's Supreme Judicial Council.

Iraq officials have arrested an ISIS member in connection with the Bourbon Street terrorist attack that left 15 people dead on New Year's in New Orleans.

U.S. officials say they have not established a direct link between the suspect in Iraq and the man who carried out the New Year's attack on Bourbon Street that killed 14 people.
