DANAMAJA, Chad, Nov 9 (Thomson Reuters Foundation) - Wearing a pastel-coloured dress embroidered with a tatty trim and speaking almost in a whisper, 17-year-old Chancelle looks like she should be in school.
But, since the age of 15, she has instead been going into isolated huts or simply to the fields to sell sex for money.
"Each week, I would meet with three or four men," the teenager, who declined to give her real name, told the Thomson Reuters Foundation.
Chancelle fled north to Chad in 2014 after her father was killed by armed militants in her native Central African Republic (CAR), where Muslim Seleka rebels and Christian and animist "anti-balaka" militias have been fighting since 2013.
A spike in violence in CAR over the last year has forced a fresh wave of refugees into Chad, the world's third least-developed country, which is also weighed down by drought, floods and conflict with the militant group Boko Haram.
The teenage girl imagined life would be easier in the vast central African country where her parents were born.
But she has gone from trading goods at a market in CAR to selling her body in Chad for as little as 250 CFA francs ($0.44) to men who sometimes beat her.
She does not even insist on condoms.
"I don't want to risk it, in case he goes to another girl," she said. "Some days, I don't eat at all. Some days, I have only 50 CFA, 100 CFA to put something in my belly."
'I DON'T HAVE A CHOICE'
Chancelle is one of thousands of so-called returnees living in Danamaja, a muddy site in southern Chad that hosts displaced people who claim to have family roots in the country but lack paperwork to prove their nationality.
For centuries, trading and cattle herding families freely criss-crossed the international border drawn up by European colonialists, which was little more than a line on a map.
When the war erupted in CAR, widespread violence and ethnic killings made life there impossible for many.
