DUBAI (Reuters) -- Al-Qaeda's No. 2 Ayman al-Zawahri has appeared in a new video apparently marking the anniversary of the September 11, 2001, attacks against the United States, according to a U.S.-based terrorism monitoring service.
Zawahri was among leading figures from the group who spoke in the 106-minute Arabic-language video, titled "The West...and The Dark Tunnel," SITE Institute said.
The video mentioned events of the past year including the global financial crisis and the election of U.S. President Barack Obama. It was posted on websites often used by Al-Qaeda supporters.
On September 14, Al-Qaeda leader Osama bin Laden warned the American people over their government's close ties with Israel in an apparently new audio tape posted on an Islamist website.
That message, titled "A Statement To The American People," was around 11 minutes long.
Analysts suggested that the posting of the latest tape might have been delayed by nearly two weeks after the anniversary of the attacks because websites have been jammed or because Al-Qaeda is finding it harder to operate.
Bin Laden and Zawahri are thought to be in the mountainous territory along the Afghanistan-Pakistan border, where U.S. forces and the Pakistani military are locked in conflict with militant groups allied to Al-Qaeda.
