About 10,000 are foreigners, including relatives of IS fighters, and observers are increasingly worried what was meant as a temporary detention facility is turning into a jihadist breeding ground.
Most of Al-Hol’s residents are people who fled or surrendered during the dying days of IS’s self-proclaimed “caliphate” in early 2019.
For staying, whether by choice or not, until the very end, they are seen as fanatical IS supporters, although the camp’s population also includes civilians displaced by battles against the jihadists.
The stigma is a challenge for Khalif who arrived in Al-Hol from Baghouz, the riverside hamlet where IS was declared definitively defeated by US-backed Kurdish forces.
“Al-Hol camp was more merciful to us than Raqa. I left the camp for my children and their education, but the situation here is not better,” she said.
In 2014, Khalif married a Saudi-born jihadist and lived with him across several IS-held regions before the two were separated by the fighting.
She hasn’t heard from her husband since she left for Al-Hol in 2019.
After a few months living in the camp, Khalif was permitted to leave along with hundreds of other Syrians under an agreement between Syrian tribal chiefs and Kurdish authorities overseeing the facility.
More than 9,000 Syrians have since been allowed to exit Al-Hol under such deals which aim to empty the camp of nationals, according to the Britain-based Syrian Observatory for Human Rights.
Khalif’s homecoming has been anything but sweet.
She said she struggles to make a living cleaning homes and faces constant suspicion.
“Some families won’t let me clean their homes because I wear the niqab (face veil) and because they think I’m an IS supporter,” she said.
“Society won’t accept me.”
Raqa tribal elder Turki al-Suaan has arranged for the release of 24 families from Al-Hol with the aim of facilitating their reintegration into their communities, but he acknowledged that it was no easy task.
“I know their families and they are from our region,” he told AFP, explaining his endorsement.
“But the intolerance that society has towards these people is a reaction to the abuses committed by IS against civilians in the area during their rule,” he said.
Raqa resident Sara Ibrahim warned that there was a danger in stigmatising people returning to Raqa from Al-Hol, most of whom are women and children.
“A lot of families in Raqa refuse to engage with these people and this... could push them towards extremism in the future,” she said.
Fearing prejudice, Amal has kept a low profile since she arrived in Raqa seven months ago from Al-Hol.
The 50-year-old grandmother and members of her family were among the last of those who flooded out of Baghouz, where the jihadists made their final stand.
“My neighbours in Raqa do not know that I was in Al-Hol camp, and I fear people will have a bad idea if they know that I was living” there, she said, a niqab covering her face.
“As long as I am comfortable with my life... there is no need for people to know,” she added.
Umm Mohammad, who also fled Baghouz three years ago, is still adjusting to life in Raqa since leaving Al-Hol late last year under tribal guarantees.
“When is society going to stop treating us like IS supporters?” she asked.
“I just want to live in peace and comfort.”
