(CNN) -- Al-Jazeera broadcast on Thursday an audiotape on which a voice identified as Osama bin Laden declares "Iraq is the perfect base to set up the jihad to liberate Palestine." Terrorist leader Osama bin Laden spoke on a video released by al Qaeda in September. The voice calls on "Muslims in neighboring countries" to "do their best in supporting their mujahedeen brothers in Iraq." "My speech to you is about the siege of Gaza and the way to liberate it," he said. "The Gaza siege is a direct result of Annapolis," he adds, apparently referring to the site of November's summit in Annapolis, Maryland, where Israeli and Palestinian leadership agreed to work toward a two-state plan.
