Dec. 22, 2004 -- -- Almost a month before the deadly attack on a U.S. base in Mosul, the U.S. Army had a warning that insurgents were planning a "Beirut type" attack on U.S. forces in northern Iraq, ABC News has learned.

On Tuesday, 22 people -- including 13 U.S. soldiers -- were killed in a daring attack on the crowded mess tent of Forward Operating Base Marez in Mosul.

A U.S. military commander however asked embedded journalists present not to report the details of some of intercepted passages during ongoing security and intelligence concerns.
