A Syrian-born German national linked to the Sept. 11, 2001, attacks was captured more than a month ago by U.S.-backed forces in Syria, the Pentagon announced Thursday.
Spokesman Eric Pahon said that Mohammad Haydar Zammar was apprehended by members of the Syrian Democratic Forces as they continue their fight against the Islamic State. In the 9/11 Commission report, Zammar was described as an "outspoken, flamboyant Islamist" who enthusiastically praised "the virtues of violent jihad." He also reportedly said he influenced Mohammed Atta, one of the hijackers, and Ramzi Binalshibh, who is accused of assisting the hijackers and al Qaeda operatives.
