Oxfam International executive director Winnie Byanyima has apologised over the British charity's handling of a prostitution scandal in Haiti involving its staff members and allegations of similar behaviour in Chad and South Sudan.
The sex scandal has forced some senior managers to resign from their roles.
Ms Byanyima says they have a dedicated confidential complaints mechanism through which victims wherever they work can report.
“From the bottom of my heart, I’m asking for forgiveness...... I am inviting anyone who has been a victim of abuse to come forward. My message to women who have suffered: I’m fighting this abuse. I’m with you. We are going to do justice. Oxfam will be a standard bearer of safety and dignity for all who interact with us,” she said on twitter.
