A New Jersey man who pleaded guilty to conspiring to aid the Islamic State (ISIS) group was sentenced on Tuesday to 15 years in prison, The Associated Press reported.

The man, Alaa Saadeh, was charged last year along with his brother and two other men, and pleaded guilty in October.

The U.S. attorney's office said the West New York resident planned to travel overseas to join ISIS and let his brother buy a plane ticket with his credit card to fly there to join the jihadist group.

At his sentencing in Newark on Tuesday, Saadeh apologized to the court and said he felt horrible about his actions, according to AP.

The sentence was the maximum under his plea agreement.

The incident illustrates the problem of radicalization which has plagued not just the United States, but other Western countries as well.

American authorities over the past year or so have arrested and charged several people of supporting ISIS. Faisal Mohammad, a California college student who stabbed four people late last year was reported to have been carrying an image of the black flag of ISIS as well as a handwritten manifesto with instructions to behead a student and multiple reminders to pray to Allah.

Just last week, a Muslim convert from Florida was arrested and charged with trying to blow up a synagogue with a fake bomb following an FBI sting operation.
