Around 700,000 Rohingya refugees have fled to Bangladesh since August 2017 due to military operations in the Rakhine State against the minority Rohingya Muslim community.
A boat carrying 70 Rohingya Muslims set out for Malaysia from Myanmar this week, two sources and a rights group said, the latest to embark on a risky sea journey.
A new United Nations report puts Myanmar's armed forces on a United Nations blacklist for carrying out rapes and other acts of sexual violence.
"The five members of a family. came back to Taungpyoletwei town repatriation camp in Rakhine state this morning", said a statement posted to the Facebook page of the government's information committee.
Several thousand Rohingya have been living in the zone since August, crammed into a cluster of tents beyond a barbed-wire fence that roughly demarcates the border zone between the two countries.
The pictures also show the family - one man, two women and a young girl and boy - receiving controversial national verification cards, which Rohingya activists have rejected, saying they are a way to deny Rohingya people citizenship. The most recent one, carrying 70 Rohingya reportedly set out from Burma toward Malaysia on Thursday, the same day the family of five returned to Rakhine.
Andrea Giorgetta from the International Federation for Human Rights (FIDH) criticised the repatriation announcement as "a public relations exercise in an attempt to deflect attention from the need for accountability for crimes committed in Rakhine state".
They have been targeted by waves of violence, systematically stripped of their citizenship and forced to live in apartheid-like conditions with severely restricted access to health care, education and other basic services.
On Friday, UNHCR said that the "conditions in Myanmar are not yet conducive for returns to be safe, dignified and sustainable", adding that "the responsibility for creating such conditions remains with the Myanmar authorities, and these must go beyond the preparation of physical infrastructure to facilitate logistical arrangements".
The confirmation comes despite United Nations warnings that it was not yet safe for families to return. Doctors Without Borders (MSF) estimated that at least 6,700 Rohingya were killed in the first month of the crackdown alone.
Myanmar officials could not be reached for further details and the post did not say whether any more returns were expected soon.
