International human rights organizations are in full swing to pressure the United Nations to address human rights violations in North Korea.

Officials from some 30 human rights organizations from 15 nations, including Human Rights Watch and Amnesty International, held an opening ceremony for the International Coalition to stop Crimes against Humanity in North Korea, or ICNK, and urged the international community to take an interest in North Korean human rights.

They said they would organize a Commission of Inquiry under the U.N. to effectively improve human rights in North Korea and seek on-site investigations to assess the situation in prison camps holding political prisoners in the Stalinist nation.

At Wednesday’s event, participants included a South Korean, now residing in Germany, whom North Korean spies kidnapped along with his family before escaping alone. He urged the international community to take interest in the Yodeok prison camp, where his family is known to be held.
