MAUNGDAW, Myanmar (Reuters) - The United Nations on Wednesday called on Myanmar to give aid agencies unhindered access to camps it has built for tens of thousands of Muslim Rohingya refugees before they can return after fleeing Myanmar military operations last year.

Bangladesh on Tuesday delayed the repatriation of the largely stateless Rohingya to Myanmar as the process of compiling and verifying the list of people to be sent back was incomplete.

But the United Nations said necessary safeguards for the refugees were still missing.

“Until the safety and wellbeing of any child returning to Myanmar can be guaranteed, talk of repatriation is premature,” UNICEF Deputy Executive Director Justin Forsyth said in a statement.

The UN Refugee Agency UNHCR said earlier “there are continued restrictions on access for aid agencies, the media and other independent observers” in Myanmar.

The UNHCR called on Myanmar “to allow the necessary unhindered humanitarian access in Rakhine State and create conditions for a genuine and lasting solution”.

More than 688,000 Muslim Rohingya and a few hundred Hindu Rohingya have fled to Bangladesh since Aug. 25 last year after the Myanmar military cracked down in the northern part of Rakhine state, amid witness reports of killings, looting and rape, in response to militant attacks on security forces.

Many in Buddhist-majority Myanmar regard the Rohingya community as illegal immigrants from Bangladesh. The United Nations described Myanmar’s crackdown as ethnic cleansing, which Myanmar denies.

FILLING OUT FORMS

Myanmar officials told a news conference on Tuesday that Bangladesh was not ready to send back the refugees as scheduled because the potential returnees hadn’t completed the forms Myanmar provided attesting to their former residency in Myanmar.

“They also have to check with the UNHCR about whether it’s voluntary,” Minister of International Cooperation Kyaw Tin told the news conference.

“They need a lot of time to fill out the forms and to determine if they really want to come back.”

A Bangladesh official who participated in the talks with Myanmar told Reuters the UNHCR would be involved in the process to “ensure the repatriations would be voluntary”.

“They (UNHCR) are already working with us...We want to make sure that the return is safe, voluntary, dignified and sustainable,” said the official, who declined to be named as he was not authorized to speak to media.

He said Bangladesh was working toward signing a memorandum of understanding with UNHCR for the repatriation and it could take “at least two months” to start the return.

But a UNHCR spokesperson in Bangladesh told Reuters the agency had not been involved “in the bilateral discussions on repatriations or signed any agreements”.

“We would like to be part of the process and discussions to ensure the reparations are voluntary, safe and sustainable and that any returns are in line with international standards,” said Caroline Gluck, UNHCR’s senior public information officer, in Cox’s Bazar.

Myanmar and Bangladesh agreed earlier this month to complete a voluntary repatriation of the refugees in two years. Myanmar says it has set up two reception centers and the temporary Taung Pyo Letwe camp to receive the first arrivals.

The plan has sparked fears in refugee camps in Bangladesh that people may be forced to return despite a lack of guarantees around their security.

Late on Tuesday, U.S. State Department spokeswoman Heather Nauert said the delay in the repatriations was a good idea and Washington was concerned about a lack of access for U.N. organizations.
