Bangladesh has delayed the repatriation of Rohingya Muslim refugees to Myanmar. A senior official says the process of compiling and verifying the list of those to be sent back is incomplete. The decision comes as tensions rise in camps holding hundreds of thousands of refugees. Some oppose their transfer back to Myanmar, saying their security has not been guaranteed. Myanmar and Bangladesh agreed earlier this month to complete the voluntary return of the refugees within two years. The process was to start on Tuesday.
