Alexandria, VA – A New Jersey man who co-founded a radical Islamic website has pleaded guilty to using the Internet to make threats against Jewish groups.

Forty-five-year-old Yousef Mohamid al-Khattab of Atlantic City started the Revolution Muslim website in 2007 with partner Jesse Curtis Morton.

Al-Khattab, who converted from Judaism and was previously known as Joseph Cohen, is the third person connected with Revolution Muslim to be convicted in federal court in Alexandria. Morton and another man, Zachary Chesser, admitted using the site to deliver thinly veiled threats against the creators of the “South Park” television show for perceived insults to the prophet Muhammad.

Al-Khattab’s guilty plea, announced Thursday, does not mention the “South Park” threats. In court documents, al-Khattab admits encouraging readers to “deal with” Jewish leaders or take other actions.
