KABUL, Afghanistan (AP) — Prisoners in some Afghan-run detention facilities have been beaten and tortured, a United Nations report said Monday, but the international organization said that the mistreatment was not the result of government policy.

The 74-page report found that detainees in 47 facilities in 24 provinces run by the Afghan National Police and the Directorate of Security suffered interrogation techniques that constituted torture under both international and Afghan law.

It said Afghan security ministries cooperated with the investigation and have taken measures to stop the abuse after being presented with the report.

The NATO-led international military coalition, also known as ISAF, announced last month that it had stopped transferring detainees to 16 of the facilities. NATO was taking action to help fix the problem before resuming the transfers, the report said.

Drafted by the U.N.’s Afghan mission, known as UNAMA, the report was based on interviews of 379 detainees spread around the facilities and conducted from October 2010 to August 2011.

It “found the use of interrogation techniques that constitute torture under international law and crimes under Afghan law, as well as other forms of mistreatment.”

The report said torture methods included suspending people by their wrists, beatings to the soles of their feet, electric shocks, twisting detainees’ genitals, removing toe nails and being put in stress positions.
