A report published last week that detailed the spy agency's "enhanced interrogation techniques" in the wake of 9/11 attacks revealed they were far more brutal than previously reported to lawmakers and the public.
"The recently revealed CIA torture crimes committed by the US, which has been conducted world-wide in the most brutal medieval forms, are the gravest human rights violations in the world," North Korea's UN envoy Ja Song-Nam wrote in a letter.
North Korea's UN ambassador also urged the UN Security Council not to call the meeting on alleged human rights abuse by Pyongyang, claiming it was "politically fabricated" and, therefore, "not at all relevant to the regional or international peace and security."
This came after 10 of the Security Council's 15 members requested a meeting on December 22 to look into the findings of a February report by a UN Inquiry Commission on human rights in North Korea that bashed Pyongyang for "systematic, widespread and grave violations of human rights."
The long list of US human rights violations under its CIA interrogation program included unlawful practices such as waterboarding, forced nudity, threats of sexual assault, prolonged sleep deprivation, stress positions and mock executions, according to the report that also confirmed the intelligence agency ran numerous "black site" prisons across the world, while many countries aided it with extraordinary renditions.
