Dec. 28 (Bloomberg) -- Osama bin Laden recorded a new message on the conflict in Iraq that will be released soon, a U.S.-based group that monitors extremist Web sites said.

The 56-minute tape was recorded by al-Qaeda's media production group, as-Sahab, and is titled ``The Way to Contain the Conspiracies,'' SITE, or Search for International Terrorist Entities, said by e-mail.

The release of the message is ``impending,'' according to the Washington-based organization. SITE didn't say whether the purported recording, that includes an address to the Islamic State of Iraq militant group, is audio or video.

Bin Laden, whose al-Qaeda network carried out the Sept. 11, 2001, attacks on the Pentagon and World Trade Center, has recorded four video and audio tapes since September from his presumed hiding places on the mountainous border between Pakistan and Afghanistan.

There have been no confirmed sightings of bin Laden since he escaped U.S.-led forces in the Tora Bora region of Afghanistan in December 2001. The U.S. Senate in July approved doubling to $50 million the reward for information leading to his capture.

In an audio message broadcast last month by al-Jazeera television, bin Laden called on European powers to end their involvement in the war in Afghanistan and cease military alliances with the U.S.

In September, as-Sahab released two bin Laden messages marking the sixth anniversary of the Sept. 11 attacks and an address in which he called on Pakistanis to rebel against their government.
