The Muslims, who were seeking refuge from the ongoing violence in Myanmar, had been in a border no man's land for two days.
The treatment of approximately 1.1 million Muslim Rohingya in mainly Buddhist Myanmar has emerged as the biggest challenge for national leader Aung San Suu Kyi.
The UNHCR reports some 5,200 people have entered Bangladesh from Myanmar since late Thursday, following an attack by Rohingya fighters against 30 police stations.
At least 109 people were killed in the recent violence in Rakhine, a lot of them militants, but also members of the security forces and civilians.
"We've been ordered not to allow Rohingya to enter Bangladesh", said one border guard, who asked to remain anonymous as he was not permitted to speak to media.
Mapim vice-president Ahmad Tarmizi Sulaiman said UN Security Council should deploy troops to Myanmar and put pressure on its government to stop the killing of Rohingya people.
The government said it was investigating whether members of worldwide aid groups had been involved in an alleged siege by the insurgents of a village in Rakhine.
"The secretary-general, who condemned those attacks, reiterates the importance of addressing the root causes of the violence and the responsibility of the fovernment of Myanmar to provide security and assistance to those in need", Stephane Dujarric, spokesman for Guterres, said.
"The Burmese government and army blame Rohingya residents and militants for the burning of some structures, but thus far have not presented evidence to support their allegations", HRW's statement said.
Speaking to Anadolu Agency, ARNO President Nurul Islam urged "the attention of the United Nations and the worldwide community, powerful countries, the OIC, ASEAN and Myanmar's neighbors to bring consistent pressure to bear on the Myanmar government and the military".
Although the cause of fire has not been ascertained yet, NY based Human Rights Watch are adamant that satellite images emerging in the aftermath clearly show burning in at least ten different areas in Northern Rakhine State.
Bangladesh is a Muslim-majority country, while Myanmar is dominantly Buddhist, with Christians occupying a very small percentage of the population. Large numbers of refugees are now stranded near the border after Bangladesh blocked their entry.
"Please save us", 61-year-old Amir Hossain told Reuters near the Bangladeshi village of Gumdhum.
The UN has said the government's response to those attacks could amount to ethnic cleansing.
