U.S. troops and CIA agents could face investigation and possible charges by the International Criminal Court after its chief prosecutor said in a report that they may have committed war crimes by torturing detainees in Afghanistan.

"Members of US armed forces appear to have subjected at least 61 detained persons to torture, cruel treatment, outrages upon personal dignity on the territory of Afghanistan between 1 May 2003 and 31 December 2014," according to the report issued late Monday by Prosecutor Fatou Bensouda's office. Bensouda didn't immediately give any for further comment Tuesday.

The report added that CIA operatives may have subjected at least 27 detainees in Afghanistan, Poland, Romania and Lithuania to "torture, cruel treatment, outrages upon personal dignity and/or rape" between December 2002 and March 2008.

Most of the alleged abuse happened in 2003-2004, the report said, adding that Afghan government forces and the Taliban were also responsible for atrocities.

Prosecutors said they will decide "imminently" whether to seek authorization to open a full-scale investigation in Afghanistan that could lead to war crimes charges.

Param-Preet Singh, associate international justice director at Human Rights Watch, welcomed the publication Tuesday.
