Four Arabs allegedly visit the headquarters of the Abu Sayyaf Islamist militant group, deep in the jungles of the southern Philippines. One of them goes by the name Ibnu bin Laden and appears to be a close relative of Osama bin Laden. They give equipment and money. Just days later, Abu Sayyaf militants seize about 50 students and teachers and demand the release of Ramzi Yousef and Sheikh Omar Abdul-Rahman from US prisons in exchange for their hostages. (They are ultimately unsuccessful in winning their demands.) Osama bin Laden’s ties to Abu Sayyaf go back at least to 1988, when it is believed he personally visited the Philippines.
