In his first video message since the death of Osama bin Laden, al-Zawahiri warned that bin Laden would continue to "terrify" the US from beyond the grave. Notably however, he did not stake a claim to take over as head of al-Qaeda.[53] He also backed the wave of Arab unrest, calling for Sharia Islamic law to be applied in Egypt, but warned Libyans that NATO's bombing campaign aimed to replace Muammar Gaddafi with a Western-backed tyrannical regime. The statement was posted on Jihadist websites.[54]
