WASHINGTON (AP) — A U.N. panel has found that crimes against humanity have been committed in North Korea and will call for an international criminal investigation, The Associated Press has learned.

The report, to be released Monday, is the most authoritative account yet of rights violations by North Korean authorities, and it is bound to infuriate the country’s unpredictable leader. But justice remains a distant prospect, not least as North Korea’s ally, China, would be likely to block any referral to the International Criminal Court.
