The Libyan militant charged in the 2012 Benghazi attacks faces his first court appearance amid tight security at the federal courthouse in Washington.

The U.S. attorney's office says Ahmed Abu Khattala (hah-TAH'-lah) will go before a magistrate judge Saturday afternoon.

Khattala is charged in connection with the attacks on Sept. 11, 2012, that killed the U.S. ambassador to Libya and three other Americans.

U.S. special forces captured Abu Khattala in Libya two weeks ago.

Officials had been questioning Abu Khattala aboard a Navy ship that transported him to the United States.
