A UN report has found that UN Peacekeepers regularly barter goods for sex with women and children in Haiti and Liberia.
The draft report by the UN Office of Internal Oversight Services says it has found that hundreds of women and children were motivated by hunger and poverty to sell sex.
They are paid with cash, jewellery, mobile phones and other items.
The report says 480 sexual exploitation and abuse claims were made between 2008 and 2013.
