More than 80 aid workers, including some employed by the World Health Organization (WHO), were involved in sexual abuse and exploitation during an Ebola crisis in the Democratic Republic of Congo, an independent commission said on Tuesday.

The probe was prompted by an investigation last year by the Thomson Reuters Foundation and The New Humanitarian in which more than 50 women accused aid workers from the WHO and other charities of demanding sex in exchange for jobs between 2018 and 2020.

In its long-awaited report, the commission found that at least 21 of 83 suspected perpetrators were employed by the WHO, and that the abuses, which included nine allegations of rape, were committed by both national and international staff.
