A United Nations human rights investigator is recommending an international strategy to press North Korea to clarify the fate of hundreds of foreign nationals allegedly abducted over decades, mainly from Japan and South Korea.

Marzuki Darusman, an independent expert, laid out the strategy in a report Monday to the U.N. Human Rights Council saying that the International Criminal Court in The Hague is "competent for prosecuting these perpetrators."

"The strategy aims at eventually shedding light on all cases of abductions and enforced disappearances allegedly committed by agents from the Democratic People's Republic of Korea," said Darusman, Indonesia's former attorney general.
