A New Jersey man who pleaded guilty to conspiring to aid the Islamic State group has been sentenced to 15 years in prison.

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 says the West New York resident planned to travel overseas to join the Islamic State group and let his brother buy a plane ticket with his credit card to fly there to join the militant organization.

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

The sentence was the maximum under Saadeh's plea agreement.
