Aid workers for charity Medecins Sans Frontiers (MSF) used prostitutes in Africa, a BBC report said yesterday citing anonymous whistleblowers who also reported boasts of trading medicine for sex.
The NGO said it took the allegations seriously but said it had been unable to confirm the claims and urged anyone with information to come forward.
The allegations follow a crisis at British charity Oxfam over claims that its workers used prostitutes while stationed in Haiti after the devastating 2010 earthquake.
A former employee based in MSF's London office told the BBC she had seen a senior staff member bring girls back to MSF accommodation while posted in Kenya.
"The girls were very young and rumoured to be prostitutes," she said, adding that it was "implicit" that they were there for sex.
She said some of the older, long-standing male aid workers took advantage of their positions.
