Women in refugee camps in Syria have been forced to offer sexual favours in return for aid from the United Nations, a report has found, in the latest accusation to hit the sector.

Aid workers would allegedly regularly harass and abuse women and girls trying to access humanitarian assistance in the war-torn country, to the point that some stopped asking.

Some victims were allegedly forced to marry locally-hired officials working for the UN and other international charities for “sexual services” in order to receive meals.

The allegations have been published by the United Nations Population Fund (UNFPA), which conducted an assessment of gender-based violence in the region last year and concluded that aid was being exchanged for sex.

The UN had been warned of such activity three years before, but the report suggests the abuse was continuing until at least late 2017.

The report, entitled Voices from Syria 2018, claimed that aid distribution sites are often perceived by women as unsafe places which are dominated by men.
