"The fate of the Western world's most wanted man Osama bin Laden remains uncertain after Al-Jazeera television admitted that a videotape of his right-hand man claiming the Al-Qaeda leader was still alive was three months old. Al-Jazeera said a videotape it aired recently showing Al-Qaeda number two Ayman al-Zawahiri claiming that bin Laden was still alive and leading 'jihad' or holy war against the West dated back to September. 'We got the videotape in September, and back then we aired what we thought were the important parts,' Al-Jazeera editor-in-chief Ahmad Sheikh told AFP. 'There was a misunderstanding today, and we aired these extracts today by mistake.'"
