'The Killing of AGSA' refers to the collective murder of opponents of the People's Democratic Party of Afghanistan between 1978 and 1979, in the Pul-e-Charkhi Prison in Kabul. 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 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 to. A list of those slain, including 5,000 victims of AGSA mass executions, was made public by the Dutch Prosecutor's Office in 2013.
Noor Mohammad was arrested in Panjishir and disappeared after he was transferred to Pul-e-Charkhi Prison in late 1978.
