Dr Shible Sahbani is humanitarian affairs specialist for the UN Population Fund (UNFPA) at Zaatari, which provides support and direct services to women and their children. "In our culture women are not allowed to go outside unless accompanied by their husbands and sons," he says.

"In Arabic culture the men have a strong role in the family, but here in the camp the male has lost his role because food is for free, and shelter is for free. He gets stressed and the result is domestic violence."

Margherita Maglietti specialises in countering gender-based violence for UNFPA. She proudly shows me the women-only group sessions being held in a prefab on the camp; they are packed with women, many clutching babies, being encouraged to speak about difficulties they face. Incongruously, men are leading the session. I ask Maglietti if she has encountered prostitution and trafficking at Zaatari. "It is a very complex topic and we have been discussing it quite a lot. We cannot say there are confirmed cases. We do know that in situations like this survival sex is part of the scenario, so it cannot be denied."

But the previous day I had been told by a senior law enforcement official that the main concern for police at Zaatari in relation to women and children is that prostitution is thriving on the camp, and that the authorities have "no idea" what to do about it. Indeed, sources close to the Zaatari security agencies tell me that a number of women have been targeted by pimps and traffickers in Zaatari who smuggle them out of the camp into one of the thriving brothels in Jordan's capital, Amman.
