American authorities on Monday arrested a 23-year-old New Jersey man on charges of conspiring to provide material support to the Islamic State (ISIS) group after he helped his brother travel to the Middle East, allegedly to join the group, AFP reported.
The Justice Department said the man, Alaa Saadeh, bought his brother a plane ticket and drove him to New York's John F. Kennedy Airport along with another person on May 5.
The brother, who was not identified, was arrested in Jordan on suspicion of supporting ISIS, according to the Justice Department.
The Justice Department said the FBI and a Joint Terrorism Task Force had been investigating Saadeh, his brother and two other suspects as they allegedly conspired to travel overseas to join ISIS.
The other alleged co-conspirators were arrested earlier this month, according to AFP.
"In recorded conversations with an informant, Saadeh revealed his support for ISIL, including the terrorist organization's use of beheadings and mass killings to impose its violent agenda. Saadeh also stated that he planned to travel overseas with CC-2 'at some point,'" the Justice Department said, referring to an unnamed co-conspirator arrested June 13 in New York and using another acronym for ISIS.
Saadeh was charged with conspiring to provide services and personnel to ISIS, aiding and abetting such attempts, and attempting to persuade a witness to lie to the FBI.
Each charge carries a maximum 20 years in prison, noted AFP.
The arrest was the latest in a string targeting ISIS sympathizers in the United States, often as a result of FBI sting operations.
In March, California resident Adam Dandach, who tried to travel to Syria last year, was charged with attempting to join ISIS.
A week earlier, three New York residents were arrested for plotting to join ISIS in Syria. One of the suspects had expressed intent to buy a machine gun and shoot police officers and FBI agents if thwarted in his plan to join ISIS.
Last October, three American teenage girls from a suburb of Denver were stopped in Germany on their way to join ISIS in Syria.
Most recently, four American citizens were arrested in the greater New York area in less than a week, on allegations of supporting ISIS and planning to carry out a bomb attack in the city.
