under younger brother Khadaffy. Basilan, Jolo, and Sulu experienced some of the fiercest fights between government troops and Abu Sayyaf through the early 1990s. Abu Sayyaf primarily operates in the southern Philippines with members traveling to Manila and other provinces. It was reported that Abu Sayyaf began expanding into neighboring Malaysia and Indonesia by the early 1990s. Abu Sayyaf is one of the smallest, but strongest of the Philippine Islamist separatist groups. Some Abu Sayyaf members studied or worked in Saudi Arabia and developed ties to mujahadeen, while fighting and training in the war against the Soviet invasion of Afghanistan. Abu Sayyaf proclaimed themselves to be mujahideen and freedom fighters. Khadaffy Janjalani leadership (1999–2007) Until his death in a gun battle on September 4, 2006, Khaddafy Janjalani was considered the nominal leader of the group by the Armed Forces of the Philippines. Then 23-year-old Khadaffy took leadership of one of the Abu Sayyaf's factions in an internecine struggle. He then worked to consolidate his leadership, causing the group to appear inactive for a period. After his leadership was secured, Abu Sayyaf began a new strategy, taking hostages. The group's motive for kidnapping became more financial than religious during this period, according to locals. Hostage money probably provides the group's financing. Abu Sayyaf expanded its operations to Malaysia in 2000, when it abducted foreigners from two resorts. This action was condemned by most Islamic leaders. It was responsible for the kidnapping and murder of more than 30 foreigners and Christian clerics and workers, including Martin and Gracia Burnham. An influential commander named Abu Sabaya was killed at sea in June 2002 while trying to evade local forces. His death is considered a crucial turning point for the group, as the number of operatives working for Abu Sayyaf sharply decreased from 1100 in 2001 to 450 in late 2002, and had since been stagnant for the next ten years. Galib Andang, one of the group's leaders, was captured in Sulu in December 2003. An explosion at a military base in Jolo, on February 18, 2006, was blamed on the group by Brig. General Alexander Aleo. Khadaffy was indicted in the United States District Court for the District of Columbia for his alleged involvement in terrorist attacks, including hostage-taking and murder, against United States nationals and other foreign nationals. Consequently, on February 24, 2006, Khadaffy was among six fugitives in the second and
