26 year old Tamerlan Tsarnaev, one of the Boston bombing suspects killed in a shootout Friday, had at least one thing in common with the Abu Sayyaf in the Philippines: they spread an apocalyptic prophecy that foretells the triumph of Islam and is a secret motivation of al-Qaeda. Its symbol: the black flag, according to former FBI agent Ali Soufan, uniting and leading an all-powerful Islamic military force that will rise up from Central Asia and defeat the infidels.
