A video purportedly from al-Qaida leader Osama bin Laden recommends Americans end their democratic system of government and embrace Islam.
US officials continue to analyze the 30-minute address, which references recent news events. News accounts indicate the tape contains no overt threats to the United States.
According to a transcript of the video, the speaker says there are two ways to end the Iraq war. He says one way is for insurgent fighters to continue to escalate the killing of American forces and the other is for Americans to do away with the democratic system of government and embrace Islam.
The speaker references Nicolas Sarkozy's recent presidential election victory in France and news accounts from the Iraq war in 2007.
A posting on an Islamist Web site late Thursday said al-Qaida intends to release the video to mark the sixth anniversary of the September 11th attacks on the United States.
The fugitive terrorist leader has not appeared in a video message since late 2004. The last audio message attributed to him was released more than a year ago.
A White House spokesman Gordon Johndroe said that six years after the attacks, this week's terror suspect arrests in Germany and Denmark and the battles against al-Qaida in Iraq and Afghanistan are reminders of the continuing threats from extremists.
Bin Laden and his deputy, Ayman al-Zawahiri, are believed to be hiding in the border area between Afghanistan and Pakistan. The United States is offering a 25-million-dollar reward for bin Laden.
