FBI agents have arrested another New Jersey man who is accused of plotting to support the Islamic State group.

Authorities on Monday charged 23-year-old Alaa Saadeh of West New York with conspiring to provide material support to the Islamic militant organization and witness tampering. They say he tried to persuade a witness to lie to the FBI.

Saadeh is scheduled to go before a judge Monday afternoon. It isn't immediately clear if he has an attorney.

The FBI and Joint Terrorism Task Force have been investigating several people in New York and New Jersey. Samuel Rahamin Topaz of Fort Lee was charged earlier this month with conspiring to join the Islamic State group.

And a Rutherford man who authorities say traveled to the Middle East in May to join the group was arrested in Jordan.

This story has been corrected to show that Topaz was charged earlier this month, not last month.
