Zulkarnaen
Aris Sumarsono, known as Zulkarnaen and Daud, is an Indonesian Islamic militant who serves as military operations chief for Jemaah Islamiyah. He was elevated to that role after the arrest of his predecessor, Riduan Isamuddin, known as Hambali. The United States Department of State Rewards for Justice Program describes him as "possibly the highest ranking leader of the Southeast Asian terrorist group Jemaah Islamiyah" and has a bounty of $5,000,000 on his head.
