The United Nations special investigator for North Korea is "strongly" urging that the U.N. Security Council refer the country to the International Criminal Court over its human rights record — and that member countries should arrest perpetrators of crimes against humanity who come into their jurisdiction.

An advance copy of the report to be presented Tuesday was obtained by The Associated Press.

Marzuki Darusman's report follows on a wave of international pressure on North Korea over its dismal human rights record, set off by a groundbreaking report by a U.N. commission of inquiry on the deeply impoverished but nuclear-armed country.

Darusman, a former member of the commission, echoes the commission's call for an ICC referral.

A resolution now with the General Assembly's human rights committee also calls for a referral.
