A Houston man pleaded guilty to charges of conspiracy to provide material support to the Islamic State (ISIS/ISIL). Omar Faraj Saeed Al Hardan, 24, was accused of plotting to bomb the Galleria and Sharpston malls in Houston.
He has been in the US since 2009 and was granted permanent residency in 2011.
Hardan was on the track to citizenship before he became involved with terrorist activity. He now faces a sentence of up to 20 years in federal prison.
The news follows the indictment of a Baltimore man on unrelated charges of conspiring to kill an American serviceman on behalf of ISIS. Federal prosecutors allege that Nelash Mohammed Das believed himself to be in contact with Islamic State operatives in Iraq and Syria whom he thought would send him $80,000 to carry out the attack.
Originally from Bangladesh, Das has been in America since 1995 and is a legal permanent resident.
Das purchased weapons through an undercover FBI informant and was arrested. He was charged for terrorist activity on October 3 and indicted by a federal grand jury on October 17.
If convicted, Das also faces up to 20 years in prison.
