The U.S. denied on Thursday an Al Qaeda claim it had executed an employee of the U.S. embassy in Baghdad.

A posting by the Al Qaeda front group the Islamic State of Iraq on an Islamic Web site known to be used by extremists claimed that U.S. Embassy "official" Zaher Abdel Mohsin Abdel-Saheb was executed Saturday as revenge for "the Muslim women who are still captives in the prisons of Shiites and crusaders."

But the embassy said it had no record of an employee by that name.

"At this time there is no record of anyone by that name who worked or has ever worked at embassy in Baghdad," a statement said.
