The U.N.'s refugee agency warns more than 500 Rohingya refugees are missing and feared dead, after a pair of boats capsized off the coast of Burma. The 530 asylum seekers departed on June 29 from Burma's Rakhine state, where Rohingya Muslims have suffered pogroms and other major human rights abuses amid fighting between Burma’s military junta and separatist fighters. Even before the latest tragedy, it’s believed nearly 300 people have gone missing or lost their lives so far this year while fleeing violence off the coast of Burma.
