"We are scaling up as fast as we can, but we need worldwide assistance to help these people".
Fleeing Rohingya say security forces shot indiscriminately, burned their homes and threatened them with death.
Analysis of active fire-detection data, satellite imagery, photographs and videos from the ground - as well as interviews with dozens of eye witnesses - reveals that security forces set more than 80 separate fires in the country's troubled Rakhine State since fighting broke out on August 25, according to an Amnesty press statement.
Retired South African Archbishop Desmond Tutu of South Africa wrote an open letter to Aung San Suu Kyi. "We are urgently appealing for more funds", he said. He also reiterated his call for the government to grant the Rohingyas nationality or at least legal status so they can get jobs, education and health care.
Last week there were 125,000 Rohingya refugees who had fled to Bangladesh and "the number has now tripled to almost 380,000", he said.
Suu Kyi has been under increasing global pressure to put an end to the crackdown and restore the rule of law in her country.
"One is the current situation in Rakhine state".
But she is facing sharp criticism for her response to the violence against Rohingya in the country.
While the Security Council was meeting, U.N. Secretary-General Antonio Guterres told reporters that ethnic cleansing is taking place against the Rohingyas.
Since August 25, the number of Rohingya refugees who have crossed the border from Myanmar into Bangladesh has now reached 389,000, Stephane Dujarric, spokesman to the UN Secretary General told reporters at the UN headquarters in NY.
"In our parliament, we have taken a resolution that Myanmar should take all their citizens back to their country and create a congenial atmosphere so that they can go back", Hasina said, according to Al-Jazeera.
He said the Nobel laureate, who has been pilloried by rights groups for failing to speak up for the Rohingya minority, would skip the United Nations General Assembly next week to tackle the crisis unfurling at home.
