Myanmar has denied all allegations of genocide and said that the violence was a legitimate response to attacks on police and military by Rohingya insurgents. The military has been accused of massive human rights violations - including rape, killing, torture, and the burning of Rohingya homes - that the United Nations and USA officials have called ethnic cleansing.
UN Secretary-General Antonio Guterres' spokesman Stephane Dujarric said the overall population of Rohingya refugees in Bangladesh is now estimated to be over one million.
Prime Minister Sheikh Hasina on Monday morning met with the visiting UNSC delegation led by Gustavo Meza-Cuadra at Gonobhaban.
Burma and Bangladesh agreed in January to complete a voluntary repatriation of the refugees within two years.
The delegation will also visit Burma after concluding its three-day visit to Bangladesh on Monday.
However, it is still unclear what a repatriating solution would be comprised of, as many Rohingya have no places to return to in their home country.
"We can not remain silent about it", he said, adding that the issue would remain at the top of the UN Security Council's agenda.
Representatives from the five permanent Security Council members - China, France, the Russian Federation, the United Kingdom and the United States - and 10 nonpermanent member states have joined the delegation, which arrived in the coastal town of Cox's Bazar, where the camps are located.More news: Migrant caravan reaches US-Mexico border
"The other thing the Security Council should do is refer the situation in Rakhine state to the International Criminal Court", Kenneth Roth, executive director of Human Rights Watch, said Friday in a speech to journalists in Yangon, Myanmar's biggest city.
Myanmar has faced intense worldwide pressure over its clampdown on the Rohingya.
She has been criticized by the West for failing to defend the Rohingyas, who Myanmar authorities consider to be Bengali immigrants from Bangladesh, although they have lived in the country for centuries.
"I will tell them my stories".
IOM's Senior Operations Coordinator in Cox's Bazar (where thousands Rohingya Muslims are putting up) John McCue, said, "We can not wait for funding to come in after the Emergency is over and possibly preventable tragedies have occurred". "They have killed my family members, they tortured us, they will kill us again", Mohammed Tayab said, standing in front of a tent where he was expecting to meet the United Nations team.
Bangladesh wants them to act "decisively and immediately" to end the sufferings of the Rohingyas.
The Security Council asked Myanmar in November to ensure no "further excessive use of military force" and to allow "freedom of movement, equal access to basic services, and equal access to full citizenship for all".
They later went to Kutupalong Camp in Bangladesh where over half a million refugees are now living. That team said in March that it found evidence of human rights violations against the Kachin, Shan and Rohingya minorities "in all likelihood amounting to crimes under worldwide law".
