Overview
In military terminology, a black site is a location at which an unacknowledged black operation or black project is conducted. A 2021 Associated Press news story defined black sites as "clandestine jails where prisoners generally are not charged with a crime and have no legal recourse, with no bail or court order."
China
Black sites are widespread within China and a Chinese black site has been alleged to exist in Dubai by a former detainee. Black sites in China are also known as "black jails."
Egypt
Black sites are used extensively by the Egyptian security services. During the Egyptian Crisis (2011–2014) hundreds of protesters alleged that torture occurred at these black sites. The Egyptian security service also operated black sites involved with the CIA's counter-terror black site program.
