The FBI arrested on Friday a man in Long Beach, California, for allegedly sending money to the Islamic State of Iraq and Syria, a designated foreign terrorist organization, according to the Department of Justice.

The U.S. Attorney's Office for the central district of California said that Mark Lorenzo Villanueva, 28, communicated with two ISIS fighters via social media, telling them: "soon, I'll be joining." Newsweek has contacted the U.S. Attorney's Office for further comment.
