(DHAKA, Bangladesh) — The gradual repatriation of more than 650,000 Rohingya Muslim refugees back to Myanmar from Bangladesh, scheduled to begin Tuesday, has been postponed amid widespread fears that refugees would be forced to return, a Bangladesh official said Monday. “The main thing is that the process has to be voluntary,” said Abul Kalam, the refugee and repatriation commissioner, adding that paperwork for returning refugees had not yet been finalized and transit camps had yet to be built in Bangladesh.
