UNITED NATIONS (AP) — The head of the commission of inquiry that accused North Korea of crimes against humanity told the U.N. Security Council on Thursday that it must take action against “a totalitarian state without parallel in the contemporary world,” and he told reporters that most council members “expressly said” the matter should be referred to the International Criminal Court.

It was the first time the council had met to discuss the unprecedented U.N. report that contains graphic details and an urgent call to action. The informal meeting comes as members of the commission push for its findings to be formally referred to the council and the ICC.
