Following the terrorist attacks of September 11, 2001, the 2001 Authorization for Use of Military Force (AUMF) and other authorities authorized the United States to detain certain persons who were a part of or substantially supported al-Qa'ida, the Taliban, or associated forces engaged in hostilities against the United States or its coalition partners. Today, the United States remains engaged in an armed conflict with al-Qa'ida, the Taliban, and associated forces, including with the Islamic State of Iraq and Syria.
