An Iraqi refugee has pleaded guilty in Texas to attempting to provide support to the Islamic State (IS) extremist group.
Prosecutors said Omar Faraj Saeed al-Hardan, 24, pleaded guilty in a Houston federal court on October 17.
He took an oath of loyalty to the IS group in November 2014 and began supporting the IS group publicly on social media, according to the plea agreement.
Hardan faces up to 20 years in prison.
In 2014 and 2015, prosecutors said he told a federal source that he planned to travel overseas to support the IS group.
He also said he had taught himself to make remote detonators and showed off a circuit board he built as a transmitter.
Hardan was arrested in January.
He entered the United States as an Iraqi refugee in 2009 after spending time in refugee camps in Jordan and Iraq, according to prosecutors.
He was later granted legal permanent residence.
