As Bashar Assad's regime fell in Syria on Sunday, relatives of detainees in the country’s various prisons have been lining up to search for their missing family members. One such prison, Sednaya prison, became infamously known as a 'human slaughterhouse' due to its alleged brutal treatment of detainees. The Sednaya prison was widely believed to be used as a tool for persecuting opposition forces and forcing them into submission. Reports indicate that thousands of opposition supporters endured horrific conditions inside, which earned the prison its infamous title. The Assad regime was recently overthrown by rebel forces, who freed the prisons by force, allowing many to finally reunite with their families after years of detention.
