A UN expert urged the Security Council Wednesday to take action on allegations of human rights violations in North Korea.

Tomas Ojea-Quintana, the UN Special Rapporteur for North Korea, spoke at the 43rd session of the UN Human Rights Council, where he stated that such claims should be referred to the International Criminal Court (ICC) for prosecution.

“[A commission] concluded that crimes against humanity have been committed and continue to be committed in the DPR Korea,” Ojea-Quintana said during his statement. He further explained that he has received information confirming findings of extermination, murder, torture, forcible transfer of populations, and other violent allegations.

Ojea-Quintana stated that the North Korean government has rejected these claims.

Human rights groups have documented and made extensive allegations about violations in North Korea. It has been reported that more than 100,000 detainees in prison camps have been exposed to torture and violence. Further, the government continues to restrict food access and the right to freedom of movement and expression.

“The UN human rights situation in the DPR Korea demands once and for all stronger actions by the United Nations,” Ojea-Quintana urged as he explained that accountability and future deterrence are needed.
