More than 16,000 Rohingya babies have been born in refugee camps located in Cox's Bazar since the influx began.
Rohingya refugees who return to Myanmar will be safe as long as they stay in the model villages built for them, the country's army chief has said, renewing fears they will be kept in settlements indefinitely.
Myanmar must hold a "proper investigation" into alleged atrocities against the Rohingya, a UN Security Council envoy said Tuesday, after the highest-level diplomatic visit to an area from which 700,000 members of the Muslim minority have been driven out.
UN Security Council envoys began a four-day visit to Bangladesh and Myanmar on Saturday to see firsthand the aftermath of a Myanmar military crackdown that Britain, the United States and others have denounced as ethnic cleansing of Rohingya Muslims.
A Myanmar minister expressed concerns on Thursday about "very poor conditions" in Rohingya refugee camps in neighbouring Bangladesh, and said repatriation of the Muslim minority should start as soon as possible due to the coming monsoon season.
Bungling, distortion and diplomatic doublespeak have hollowed out the deal to repatriate Rohingya from Bangladesh to Myanmar, with refugees refusing to return to a homeland that remains perilously insecure.
Five family members among the 700,000 Rohingya Muslims who fled Myanmar after a military crackdown was launched last year, returned from the border region into Myanmar.
Rohingya refugees will be allowed to return to Myanmar "as soon as possible", a minister said, despite a stillborn repatriation process and UN warnings that the safety of returnees could not be guaranteed.
News of the rescue comes several days after the arrival in Malaysia of another boat carrying dozens of members of the persecuted minority from Myanmar.
Bangladesh officials said on Monday a fishing boat carrying Rohingya Muslims to Southeast Asia did not set sail from its shores, where close to one million refugees live in congested camps.
The UN's top official on preventing genocide said Tuesday efforts were made to "cleanse" the Rohingya and that returning the persecuted Muslim minority to Myanmar risked further atrocities against them.
