Al-Qaeda’s deputy leader Aiman al-Zawahri has urged Muslims to fight NATO and the US if their forces invade an Islamic country in a video message issued on Thursday. The footage was recorded before western air assaults started in Libya. Aiman al-Zawahri also urged Muslims to fight the pro-Qaddafi forces. Al-Qaeda and its North African division had called for Qaddafi’s removal from power and the establishment of Sharia (Islamic law) in the country. In the video posted on online militant forums on Thursday, Zawahri said that neighboring Tunisia, Algeria and Egypt, in particular, must rise up and confront both the forces of Qaddafi and NATO.
