However, many refugees have refused to go back unless their safety can be guaranteed and Myanmar grants their demands to be given citizenship and inclusion in a list of recognised ethnic minorities.
Two Reuters journalists detained for two months by Myanmar authorities were arrested for investigating a massacre of 10 Rohingya men, the news agency said in a report that detailed the grisly killings. Two police officers were also arrested, on the same charge of violating a colonial-era law.
Human rights organisations have documented widespread abuse by the Myanmar Army against the Rohingya, including murders and rapes, during its military campaign against the minority, which the United Nations has described as a "textbook example of ethnic cleansing".
We cannot help but ask, now that Rakhine Buddhists and Myanmar's security personnel themselves have come forward and substantiated evidence of the mass murder by the military and Buddhist villagers, how can Myanmar continue to deny the truth?
Johnson, who later flew to Rakhine state, wrote on Twitter that he raised the "importance of [Myanmar] authorities in carrying out full & independent investigation into the violence in Rakhine".
On Jan 10, the military had said the 10 Rohingya men belonged to a group of 200 "terrorists" who had attacked security forces. The next hearing is scheduled for Feb.14.
Mr Johnson will later be taken on a tour of Rakhine State - the area the refugees fled from - by the Myanmar military and will also meet the chair of the Advisory Board on the Rakhine Advisory Commission, Surakiart Sathirathai.
In November, Bangladesh and Myanmar signed an agreement to begin repatriating Rohingya refugees by the end of January, but Dhaka suspended it at the last minute.
Their report, which was released on Friday, details events surrounding the massacre, in which 10 Rohingya men from Inn Din village were hacked to death or shot by Buddhist neighbors or soldiers in September 2017.
The country's de facto leader, Nobel peace laureate Aung San Suu Kyi, has faced global condemnation for her apparent inaction in the face of the widely alleged reports of atrocities committed against the Rohingya, which the United Nations says might amount to genocide.
