The U.N. is calling for an investigation into reports that Indian authorities in New Delhi rounded up dozens of Rohingya refugees, including children, then took them by ship to the Andaman Sea, where they pushed them into the open water near Burma’s coast with nothing but life jackets. Their whereabouts remain unknown. The move by the government of Prime Minister Narendra Modi comes amid an intensifying crackdown on Muslim minorities across India and as tensions escalate with neighboring Pakistan.
