A video posted on an internet site known to be used frequently by Al Qaeda followers Wednesday showed the group's deputy leader Ayman Al Zawahri calling on his followers to attack oil sites in Muslim countries.
"I call on mujahideen to concentrate their attacks on Muslims' stolen oil, from which most of the revenues go to the enemies of Islam while most of what they leave is seized by the thieves who rule our countries," Zawahri said in the video, according to Reuters.
Zawahri also said in the video that Osama bin Laden is still alive, and that he continues to lead a holy war against enemies of the West.
"Al Qaeda for holy war is still, thanks to God, a base for jihad (holy war). Its prince Sheikh Osama bin Laden, may God protect him, is still leading its jihad."
He added, "I bring a message of joy to all Muslims and mujahideen that al Qaeda, thanks to God, is spreading and expanding and strengthening."
The recording seemed to have been filmed to mark the fourth anniversary of the Sept. 11, 2001 attacks.
