 U.S. prosecutors on Saturday say they have charged a Saudi-born Canadian man for aiding the Islamic State militant group. The Canadian alleged 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 the man identified as Mohammed Khalifa as a leading figure in the English-language media unit of the Islamic State in Iraq and Syria, also known as ISIS. It 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, a militia group that controls parts of Syria. If convicted, Khalifa faces up to life in prison. NEWS OPDATES
