Known as the "Killing of AGSA," it refers to the collective murder of opponents of the People's Democratic Party of Afghanistan in the Pul-e-Charkhi Prison in Kabul between 1978 and 1979. The Afghan Intelligence Office, or AGSA (Afghan Agency for Safeguarding National Interest), led by Asadullah Sarwari, had arrested nearly 150,000 people, out of which an estimated number of 27,000 political prisoners were put to death without a single trial, probe, or even allegation. Many Afghan families had no idea where their loved ones had disappeared in the latter part of 1978 and early 1979. A list of those slain that included 5,000 victims of AGSA mass executions was made public by the Dutch Prosecutor's Office in 2013.
