A top UN official recounted to the Security Council on Tuesday "heartbreaking and horrific accounts of sexual atrocities" by Myanmar soldiers against Rohingya women, urging the body to visit the region and demand an end to attacks on civilians.
Pramila Patten, special envoy of UN Secretary-General Antonio Guterres on sexual violence in conflict, said one woman told her she was held by Myanmar troops for 45 days and raped repeatedly, while another woman could no longer see out of one eye after it was bitten by a soldier during a sexual assault.
"Some witnesses reported women and girls being tied to either a rock or a tree before multiple soldiers raped them to death," Patten told the Security Council.
"Some women recounted how soldiers drowned babies in the village well. A few women told me how their own babies were allegedly thrown in the fire as they were dragged away by soldiers and gang raped," she said.
Patten said the 15-member Security Council should visit Myanmar - also known as Burma - and Cox's Bazar, where more than 646,000 refugees have fled to since violence erupted in Myanmar's northern Rakhine State on August 25.
She said that a Security Council resolution demanding an immediate end to violations against civilians in Rakhine state and outlining measures to hold the perpetrators accountable "would send an important signal."
Myanmar's army released a report last month denying all allegations of rapes and killings by security forces.
"This is unacceptable," said US Ambassador to the United Nations Nikki Haley. "Burma must allow an independent, transparent and credible investigation into what has happened."
"While we are hearing promises from the government of Burma, we need to see action," she said.
Last month the Security Council urged the Myanmar government to "ensure no further excessive use of military force in Rakhine state."
China's Deputy UN Ambassador Wu Haitao said the crisis had to be solved through an agreement between Myanmar and Bangladesh and warned that any solution "reached under strong pressure from outside may ease the situation temporarily but will leave negative after effects."
UN political affairs chief Jeffrey Feltman pushed on Tuesday for the United Nations to be involved in any operation to return Rohingya.
"Plans alone are not sufficient. We hope Myanmar will draw upon the wealth of expertise the UN can offer," Feltman told the Security Council.
