The United Nations refugee agency has launched an investigation into newly emerged reports that two vessels carrying Rohingya, the long-persecuted ethnic minority from Myanmar, overturned in the Bay of Bengal while attempting a dangerous ocean crossing. In a public statement released Tuesday, the Office of the U.N. High Commissioner for Refugees (UNHCR) confirmed that the two boats are believed to have departed Rakhine State, western Myanmar, in late June before sinking.
