The U.S. has charged a Saudi-born Canadian man for aiding the Islamic State militant group.
The man has been identified as Mohammed Khalifa, seen here in an interview.
Prosecutors allege that he tossed grenades in battle and worked with propagandists who publicized the beheading of hostages including U.S. journalist James Foley.
The Department of Justice described him as a "leading figure" in the English-language media unit of the Islamic State in Iraq and Syria.
The department said Khalifa narrated English-language recruitment videos and was a battlefield fighter before he was captured in 2019 by the U.S.-backed Syrian Democratic Forces.
He was recently arrested by the FBI.
Charges against him were unsealed on Saturday in the U.S. District Court for the Eastern District of Virginia.
If convicted, Khalifa faces up to life in prison.
