Context: (CNN) -- Radical Islamic websites Wednesday posted an Arab Spring audio message purportedly recorded by Osama bin Laden shortly before he was killed. 

The recording, which is more than 12 minutes long and was released by al Qaeda's media arm, As-Sahab, lists the speaker as bin Laden and calls him "the martyr of Islam." 

The audio begins with a prayer and remarks reportedly made by bin Laden about anti-government protests and uprisings earlier this year in several African and Middle East countries. 

CNN, which translated the audio, could not confirm its authenticity. 

The Islamic date with the audio indicates it was recorded between April 4 and May 3. 

Its posting came one day before U.S. President Barack Obama was to deliver a speech highlighting his administration's revised policies toward the Arab region in the wake of the Arab Spring protests.

Just last week, a U.S. official told CNN a message with similar topics was seized at bin Laden's Pakistan compound during the May 2 raid by U.S. commandos. 

The official, who spoke on the condition of anonymity because of the classified nature of the information, has not yet compared the recordings. 

The audio on the websites calls for solidarity among Muslims. 

"My Muslim Umma (nation), we are monitoring with you this great historic event, and we join you with your joy and delight, so congratulations on your victories, and may God have mercy on your martyrs. May He cure your injured and grant the release of your prisoners."
