Hambali , now in U.S. custody since 2003 , was the leader of the southeast Asia terrorist group Jemaah Islamiyah , which later became associated with al-Qaeda , along with Abu Sayyaf in the Philippines . Hambali was also a close friend of the later al-Qaeda 9/11 mastermind , Khalid Shaikh Mohammed , also now in U.S. custody since 2003 . Mohammed in turn had become one of the original 22 FBI Most Wanted Terrorists , indicted for his role in the planning of the 1995 terrorist plot named Operation Bojinka , to bomb eleven U.S. airliners . It was accidentally discovered and foiled in Manila , Philippines . The Bojinka bombs were in the process of being constructed by Mohammed 's nephew , Ramzi Yousef , who was , by then , already wanted by the United States Department of Justice as one of the FBI 's Ten Most Wanted Fugitives for his own earlier role in the 1993 World Trade Center bombing
