NEW YORK (KTLA) -- FBI officials are looking into an apparent death threat against late-night talk show host David Letterman by an extremist website frequented by al-Qaida.

The website, Shumukh-al-Islam, reportedly called on its followers to "cut the tongue of this lowly Jew and shut it forever."

The threats are believed to be in response to jokes Letterman made about the death of accused terrorist leader Ilyas Kashmiri, who was killed by a U.S. airstrike in Pakistan in June.

Umar al-Basrawi, the man who first posted the threat, wrote "He showed his evil nature and deep hatred for Islam and Muslims, and said that Ilyas Kashmiri was killed and he joined bin Laden."

"We ask Allah to paralyze his tongue and grant the sincere monotheists his neck."

Letterman, by the way, is not Jewish.

A rep for Letterman's Worldwide Pants production company respectfully declined to comment.

FBI officials are looking into the post.

"In the post 9/11 world , we take all of these threats seriously," FBI spokesman Peter Donald told CNN.
