U.S.-based monitoring groups say the al-Qaida terrorist network intends to release a new video recording of Osama bin Laden on or before next week's sixth anniversary of the September 11 attacks on the United States.

No photos or video of Bin Laden have been seen since late 2004, and the last audio message attributed to the fugitive terrorist leader was heard more than a year ago.

Two private monitoring organizations - SITE intelligence Group and IntelCenter - say an announcement, in the name of al-Qaida's media-production arm, al-Sahab, seen on an Islamist website this week indicates the new al-Qaida video is about to be released.

A photograph said to be a recent portrait of bin Laden accompanied the announcement.

The United States is offering a $25 million reward for bin Laden, but he has eluded capture since the 2001 attacks on New York and Washington. President Bush says the U.S. will find Osama bin Laden and bring him to justice, no matter how long it takes.
