Web sites usually used by Islamic militant groups announced a new, major Al Qaeda video would be released soon.

"Coming soon God willing? Wait for the big surprise," said an Internet banner Thursday next to a Web animation that shows photos Al Qaeda chief Usama bin Laden and some of his key deputies, along with pictures of U.S. President George W. Bush and Pervez Musharraf of Pakistan.

The advertisement for the forthcoming video was signed by As-Sahab, the multimedia branch of Al Qaeda, and was expected to be an important release on a major recent attack, two U.S.-based terrorism monitoring groups said.
