ADRE, Chad (AP) — Crossing into Chad, the 27-year-old thought she’d left the horrors of Sudan’s war behind: the bodies she ran over while fleeing, the screams of girls being raped, the disappearance of her husband when gunmen attacked. But now she says she has faced more suffering — being forced as a refugee to have sex to get by.

She cradled her 7-week-old son, who she asserted was the child of an aid worker who promised her money in exchange for sex.

“The children were crying. We ran out of food,” she said of her four other children. “He abused my situation.” She and other women who spoke to The Associated Press requested anonymity because they feared retribution.

Some Sudanese women and girls assert that men, including those meant to protect them such as humanitarian workers and local security forces, have sexually exploited them in Chad’s displacement sites, offering money, easier access to assistance and jobs. Such sexual exploitation in Chad is a crime.

Hundreds of thousands of people, most of them women, have streamed into Chad to escape Sudan’s civil war, which has killed over 20,000 people. Aid groups struggle to support them in growing displacement sites.

Three women spoke with the AP in the town of Adre near the Sudanese border. A Sudanese psychologist shared the accounts of seven other women and girls who either refused to speak directly with a reporter or were no longer in touch with her. The AP could not confirm their accounts.

Daral-Salam Omar, the psychologist, said all the seven told her they went along with the offers of benefits in exchange for sex out of necessity. Some sought her help because they became pregnant and couldn’t seek an abortion at a clinic for fear of being shunned by their community, she said.

“They were psychologically destroyed. Imagine a woman getting pregnant without a husband amid this situation,” Omar said.

Sexual exploitation during large humanitarian crises is not uncommon, especially in displacement sites. Aid groups have long struggled to combat the issue. They cite a lack of reporting by women, not enough funds to respond and a focus on first providing basic necessities.

The U.N. refugee agency said it doesn’t publish data on cases, citing the confidentiality and safety of victims.

People seeking protection should never have to make choices driven by survival, experts said. Nidhi Kapur, who works on preventing sexual exploitation and abuse in emergency contexts, said exploitation represents a deep failure by the aid community.

Yewande Odia, the United Nations Population’s Fund representative in Chad, said sexual exploitation is a serious violation. U.N. agencies said displacement camps have “safe spaces” where women can gather, along with awareness sessions, a free hotline and feedback boxes to report abuse anonymously.

Yet many of the Sudanese women said they weren’t aware of the hotline, and some said using the boxes would draw unwanted attention.

The Sudanese woman with the newborn said she was afraid to report the aid worker for fear he’d turn her in to police.

She said she approached the aid worker, a Sudanese man, after searching for jobs to buy basic necessities like soap. She asked him for money. He said he’d give her cash but only in exchange for sex.

They slept together for months, she said, and he paid the equivalent of about $12 each time. After she had the baby, he gave her a one-time payment of approximately $65 but denied it was his, she said.

The man was a Sudanese laborer for Doctors Without Borders, known by its French acronym MSF, she said.

Two other Sudanese women said Chadian men working at MSF sites— one wearing MSF clothing — solicited them after they applied for work with the organization. The men took their phone numbers and repeatedly called, saying they’d give them jobs for sex. Both women said they refused.

Christopher Lockyear, MSF’s secretary general, said the organization was not aware of the allegations and wanted to investigate. “Asking for money or sex in exchange for access to care or a job is a clear violation of our behavioral commitments,” he said.

MSF would not say how many such cases had been reported among Sudanese refugees in Chad. Last year, out of 714 complaints made about MSF staff behavior where it works globally, 264 were confirmed to be cases of abuse or inappropriate behavior including sexual exploitation, abuse of power and bullying, Lockyear said.

Lockyear said MSF is creating a pool of investigators at the global level to enhance its ability to pursue allegations.

One woman told the AP that a man with another aid group also exploited her, but she was unable to identify the organization. Omar, the psychologist, said several of the women told her they were exploited by aid workers, local and international. She gave no evidence to back up the claims.

Another woman, one of the two who alleged they were approached after seeking work with MSF, said she also refused a local policeman who approached her and promised an extra food ration card if she went to his house.

Ali Mahamat Sebey, the head official for Adre, said police are not allowed inside the camps and asserted that allegations against them of exploitation were false. With the growing influx of people, however, it’s hard to protect everyone, he said.

The women said they just want to feel safe, adding that access to jobs would lessen their vulnerability.

After most of her family was killed or abducted in Sudan’s Darfur region last year, one 19-year-old sought refuge in Chad. She didn’t have enough money to support the nieces and nephews in her care. She got a job at a restaurant in the camp but when she asked her Sudanese boss for a raise, he agreed on the condition of sex.

The money he paid was more than six times her salary. But when she got pregnant with his child, the man fled, she asserted. She rubbed her growing belly.

“If we had enough, we wouldn’t have to go out and lose our dignity,” she said.
