Libya’s political and security crisis deepens as two rival governments compete for legitimacy, control of vital institutions, and international support. A UN-brokered political deal has yet to bear fruit. Continuing armed clashes have displaced hundreds of thousands of people and interrupted access to basic services, including fuel and electrical power. Forces engaged in the conflict are guilty of arbitrary detention, torture, unlawful killings, indiscriminate attacks, disappearances, and the forceful displacement of people. In addition, armed groups that pledged allegiance to the extremist group Islamic State (also known as ISIS) are also summarily killing people in areas under their control.
