Abdul Basit Usman, a Filipino citizen, is a bomb-making expert with links to the Philippines-based Abu Sayyaf Group and Jemaah Islamiyah terrorist organizations operating in the southern Philippines. Due to these associations, US authorities consider Basit to be a threat to US and Filipino citizens and interests. Basit is believed to have orchestrated several bombings that have killed, injured, and maimed many innocent civilians.

Basit has been indicted in the Philippines for his role in multiple bombing incidents since 2003, and the Government of the Philippines has issued a warrant for his arrest. He is believed to be hiding in central Mindanao.
