People unaccounted for in the Syrian prison system, presumed to have been killed or still under detainment, according to the Syrian Network for Human Rights. A New York Times investigation detailed the system of imprisonment and torture overseen by the government of Syrian President Bashar al-Assad, where an estimated 13,983 have died due to torture by Syrian regime forces between March 2011 and March 2019. The detention system is an expansion of a system first enacted by President al-Assad’s father, utilized to clamp down on the dissent response to Arab Spring protests, which began in December 2010.
