An ex-senior UN member has stated that allegations of sexual assault and corruption at the UN should be probed as soon as possible by an impartial panel.
Purna Sen's remarks come after a BBC investigation found that a number of UN employees who sought to uncover alleged corruption were fired.
Ms Sen stated that the United Nations should "step up" and follow any recommendations given by the group.
According to the BBC, the UN is focused on ensuring that individuals feel secure reporting abuse.
The BBC documentary The Whistleblowers: Inside the UN explores charges of corruption, management cover-ups, and sexual assault inside the UN.
Staff employees who attempted to report allegations said they were punished for coming up, and several were fired.
Ms Sen, who was named spokesman on harassment, assault, and discrimination at the United Nations in 2018, claimed in the video that women at the UN have been "approached, harassed, and raped." "The more males get away with it," she continued, "the more they will continue to do it."
She told BBC Newsnight that the "very sad" testimony do not surprise her.
"It implies that the safety of top personnel inside an organisation is often more important than the safety of individuals who aren't influential.
"It implies that there is significant friction inside an organisation that not only respects and campaigns for human rights, but is also the originator of many of these rights - yet it hasn't learnt to bring them together.
Ms Sen stated that she would like UN Secretary-General António Guterres to form a diverse external group to review worker experiences and make recommendations for specific solutions.
Mr Guterres' office stated in a statement that it was open to any external examination of its measures "to prevent misbehaviour of any form."
Stephane Dujarric, a spokesperson for UN Secretary General Ban Ki-moon, told the BBC's Newshour that Ban has "taken this quite seriously since he came into office."
"We will continue to do everything we can to assist victims, and we are working to improve protocols and ensure that individuals feel secure reporting abuse," he said.
"There is full openness and we have an internal independent committee," Mr Dujarric replied when questioned about external supervision.
