Is the Abu Sayyaf linked to al Qaeda?
Yes, say U.S. and U.N. officials. They say Abu Sayyaf has received funding from al Qaeda, and that several members trained in Osama bin Laden's camps in Afghanistan. Bin Laden's brother-in-law, Mohammed Jamal Khalifa, has been a frequent visitor to Zamboanga City, an Islamic hotbed in Mindanao. He is suspected of funneling money to the rebels through Islamic charities and a university in the city.
