GENEVA (Reuters) - Conditions in Myanmar s northern Rakhine state  are not in place to enable safe and sustainable returns  of more than 600,000 Rohingya refugees who fled violence to Bangladesh since late August, the United Nations refugee agency UNHCR said on Friday. UNHCR said it had still not seen a repatriation agreement signed by the two countries on Thursday, but stressed that any returns by the  traumatized  group must be safe and voluntary. Spokesman Adrian Edwards told a news briefing:  It is important that international standards apply, and we are ready to help.
