Meet the Mastermind Behind Muslim Violence in the Philippines

A second month of fighting between government troops and Muslim rebels in a southern Philippine city is turning to a search for a man sought by Manila as well as the United States for his leadership in terrorism over the past 20 years.

Philippine troops believe Isnilon Totoni Hapilon may be hiding in the largely demolished city of Marawi. Troops attacked Marawi May 23 because they feared Hapilon’s historically violent Abu Sayyaf group was forming links with another rebel organization there.
