I'm just walking into the women's wing or what's left of it. You can see all around evidence of how intense the blaze was. There are burn marks here on all the walls and lots of ash at my feet. And there are a lot of belongings strewn around here. Piles of clothing, lots of cooking utensils. On the ground I can see a copy of the Bible.

You can just imagine what was endured by the women and children who were trapped here, locked in, unable to get away. Two survivors from the women's prison have come back for the first time. They want to tell their story. In silence, they walk through the charred ruins. 22-year-old Pascaleen has her hand to her mouth in horror. Nadine, who is 23, is soon in tears.

Pascaleen, can you tell me what happened to you that night?

That night, the prison was engulfed by chaos and by fire. Most of the guards long gone. By morning, thousands of the men had managed to break free. But the women were still trapped, among them Nadine, who was raped by two men and saw women and children dying around her.

Do you have any faith in justice here in the DRC?

I'm just coming into a tent in the grounds of a hospital in Goma. I've come here to meet a 25-year-old woman, Sifa Mohammed. Sifa was badly burned in the fire in the prison. Her right arm is very heavily bandaged and you can see burn marks on her arm and on her face. She was in prison without being convicted of anything, she says, and she was with her two-year-old daughter, Esther.

They had all gone. Sifa, I'm sorry to ask this question, but can you tell me what happened to your daughter, Esther?

The full story of what happened in the prison may never be known. Sifa says no one is looking for the truth. She and the other survivors we spoke to have not been contacted by anyone. Not the rebels in control in Goma now, nor the government in Kinshasa, which used to run the prison.

It's extremely rare to get access inside these walls. There's iron gate after iron gate. All along this corridor, there are numbered cells. There are guards here, all of them with their faces covered, one standing outside each of the cells. Hello. We've been allowed to get a look inside one of the cells, but we've been told we can't speak to the men. The cell is quite full.

There are men sitting on the ground, lining both sides, sitting on blankets and thin mattresses. This is the biggest detention centre for IS prisoners. Most of the men being held here were with IS until the group made its last stand. Kurdish security sources tell us they were deeply committed to the IS ideology. What happens to these prisoners is one of the big questions facing this country.
