NEW YORK (AP) — A frequent contributor to a jihadist website has threatened David Letterman, urging Muslim followers to “cut the tongue” of the late-night host because of a joke the comic made on his CBS show.

The Site Monitoring Service, a private intelligence organization that watches online activity, said Wednesday that the threat was posted a day earlier on the Shumuka al-Islam forum, a popular Internet destination for radical Muslims.

The contributor, who identified himself as Umar al-Basrawi, was reacting to what he said Letterman did after the U.S. military announced on June 5 that a drone strike in Pakistan had killed al Qaida leader Ilyas Kashmiri.

Al-Basrawi wrote that Letterman had made reference to both Osama bin Laden and Kashmiri and said that Letterman had demonstrated on his neck how Kashmiri died.

There was no comment from CBS or Letterman.
