A mother forced to drown her own baby and a prison camp inmate compelled to eat rodents and lizards just to survive -- these are some of the horrific experiences documented by a United Nations inquiry into human rights violations in North Korea. According to the man who headed up the study, examples of "unspeakable atrocities" collected to date suggest widespread abuses on a scale requiring an international response. Michael Kirby, chair of the three-member commission of inquiry, told the U.N.'s Human Rights Council Tuesday, "What we have seen and heard so far -- the specificity, detail and shocking character of the personal testimony -- appears without doubt to demand follow-up action by the world community, and accountability on behalf of the Democratic People's Republic of Korea." The remarks were contained in a draft report updating the council on the work of the commission, ahead of a final report to the U.N. General Assembly slated for March. Pyongyang has refused to cooperate with the investigation and rejects its validity.
