In a three-part audio message which the jihadist network's media arm Al-Sahab said was recorded before US forces killed bin Laden on May 2, Zawahiri addressed the populations of Libya, Syria and Egypt in turn. SITE Intelligence, which monitors jihadist Internet forums, said the Egyptian militant warned Libyans the NATO-led aerial bombing campaign against Moamer Kadhafi seeks to replace the strongman with its own tyrannical regime. He also called upon the Muslims of North Africa to join the fight against Kadhafi and to obtain weapons, while criticising Egypt's military for not coming to the aid of Egyptian expatriates residing in Libya.
