An Iraqi man who came to the United States as a refugee from Syria was arrested in Sacramento on Thursday on a federal charge of making a false statement involving international terrorism, the U.S. Department of Justice said.

In a criminal complaint released Thursday, the FBI said Aws Mohammed Younis Al-Jayab, 23, lied about traveling back to Syria and about posting on social media his support for what the government said were terrorist groups.

The Justice Department said Al-Jayab, a Palestinian born in Iraq, came to the United States in 2012 as a refugee from Syria.

The following year, he went overseas, telling officials later that he had gone to Turkey to visit family.

The complaint includes numerous social media postings and other communications in which Al-Jayab discusses war, using assault rifles and training with militants. He also says he is in Syria.

"We can confirm that there was a national security-related arrest today," said Lauren Horwood, a spokeswoman for U.S. Attorney Benjamin B. Wagner. "There is no current threat to public safety associated with this arrest."

Al-Jayab is scheduled to appear in federal court in Sacramento on Friday, Horwood said.
