GENEVA (AFP) - UN human rights chief Navi Pillay on Monday demanded an international probe into the alarming human rights situation in ultra-authoritarian North Korea, decrying more than a half-century of devastating abuses. “It is time the international community took a much firmer step towards finding the truth and applying serious pressure to bring about change for this beleaguered, subjugated population of 20 million people,” the UN High Commissioner for Human Rights said in a rare and strongly worded statement on North Korea. Pillay lamented the “deplorable human rights situation” in North Korea, “which in one way or another affects almost the entire population and has no parallel anywhere in the world.”
