“Ayman al-Zawahiri, al-Qaeda’s number two, has warned that Osama Bin Laden will continue to ‘terrify’ the US from beyond the grave. The statement was posted on Jihadist websites. …This is the first time al-Zawahiri has spoken publicly since Bin Laden’s death. …’The sheikh has departed, may God have mercy on him, to his God as a martyr and we must continue on his path of jihad to expel the invaders from the land of Muslims and to purify it from injustice,’ Zawahri says. ‘Today, and thanks be to God, America is not facing an individual or a group, but a rebelling nation, which has awoken from its sleep in a jihadist renaissance.’ ”
