The founder of a radical Islamic website that praised figures like Osama bin Laden and Fort Hood shooter Nidal Hasan has been sentenced to 2½ years in prison for using the site to threaten Jewish groups.

Yousef al-Khattab, 45, had converted from Judaism and started the Revolution Muslim website in 2007. He was born Joseph Leonard Cohen and was brought up in a Jewish home in New Jersey and in Brooklyn.

Al-Khattab admitted posting articles encouraging readers to take unspecified action against Jewish leaders and publishing names and addresses of Jewish leaders and synagogues.

Al-Khattab pleaded guilty in US District Court in October to using his position as a leader of the ‘Revolution Muslim’ websites to incite violence against Jews.

Prosecutors say numerous people who have been convicted of terrorism-related offenses were readers of Revolution Muslim.

Defense lawyers say it is conjecture to assume people were inspired to plot attacks by Revolution Muslim.
