A U.N. special investigator is welcoming his first meeting with North Korean officials but warns that the country must be held accountable for human rights abuses.

Marzuki Darusman presented his annual report to the U.N. General Assembly's human rights commission Tuesday, a day after meeting with North Korean officials for the first time.

Darusman's report urges the Security Council to refer North Korea to the International Criminal Court over its rights record.

North Korea has staged a public push in recent weeks to stop a growing international call for such a referral. At the meeting with Darusman, North Korean officials raised the possibility of him visiting their country.

Darusman said North Korea's willingness to meet "opens up possibilities" but warned it was important to "pursue accountability and take action against individuals visibly involved" in abuses.
