Mainly Buddhist Myanmar denies atrocities against Rohingya, and said in September that almost 400 people died in the fighting, mostly Rohingya insurgents.
MSF said the agreement was "premature" pointing out that "currently people are still fleeing" and reports of violence have come even in recent weeks.
Among the dead children below the age of five, MSF said more than 59 percent were reportedly shot, 15 percent burnt to death, 7 percent beaten to death and 2 percent were killed by landmine blasts. The military operation, which many including United Nations calls as an "ethnic cleansing" led to a mass displacement of Rohingya civilians into Bangladesh. On 25 August 2017, a "clearance operation" launched by Myanmar's Army in repose to an attack by a Rohingya militant group led to the massive violence in the Rakhine State.
Reuters news agency called on Myanmar to immediately release two of its journalists who were arrested for possessing "important secret papers" obtained from two policemen who had worked in Rakhine state, where violence widely blamed on security forces has forced more than 630,000 minority Rohingya Muslims to flee into neighboring Bangladesh.
MSF medical director Sidney Wong said: "We met and spoke with survivors of violence in Myanmar, who are now sheltering in overcrowded and unsanitary camps in Bangladesh".
"I think it's important that the worldwide community does everything possible" to win the release of the journalists and also to end the dramatic human rights violations that have caused many to flee their country, he said Thursday.
It denied killing any civilians, burning their villages, raping women and girls, and stealing possessions. "We heard reports of entire families who perished after they were locked inside their homes, while they were set alight".
During that one-month period, the mortality rate among Rohingya soared to eight deaths per 10,000 people.
Senior European officials on Friday criticized the Myanmar government's arrest of two Reuters journalists and called for their release.
"We made a decision to help our Muslim brothers and sisters in Myanmar. We can't make any comment on that number, because MSF is only an I [nternational] NGO", the minister added.
The group also warned there was still very limited access for aid groups into Rakhine state.
