"I KEPT the four girls in an abandoned house. Each night I would have sex with a different one," a grubby looking man said, unperturbed.
"Sometimes they seemed scared, but they never said no. They were all virgins when I got them and more beautiful than you can imagine."
It was the world's single largest military operation in nearly 15 years.
The battle for the northern Iraqi city of Mosul, the largest offensive in the war against Islamic State - and no doubt, the bloodiest - took a mighty three years for allied forces to remove Islamic State's tight grip.
But with freedom, comes vengeance - and makeshift courts have been set up, notably the Nineveh Criminal Court in the Al- Hamdaniya district east of Mosul, approximately 30 minutes drive from the city, to condemn those who fought against them.
The suspected Islamic State fighter giving his story of events at the investigations court plead to guilty to four counts of kidnap and rape of women belonging to the minority Yazidi sect and 10 counts of the murder of its men.
He "seemed unrepentant as he confessed to his crimes," noted the Telegraph 's Josie Ensor from Qaraqosh, Iraq.
The 40-year-old Mohammed Ahmed was "struggling for breath and shaking. His eyes rolled and his chin lolled down to his chest. He had been made to wait outside in the blistering Iraqi sun since early morning and was suffering", Ms Ensore wrote.
Mr Ahmed began detailing his crimes, including the murder of a group of Yazidi men and boys in a primary school in 2014.
"I shot them there in the school hall," he told the court. "I think I killed 10 or 12 of them, including some children."
He was then instructed to take the "prettiest" girls in the town where they were sold into slavery and passed around senior members of the group.
He was given four women, between 22 and 30, where he kept them in an abandoned house and had sex with "a different one" each night.
"They were part of my salary. I received R8,000 a month and the women as a bonus," he said.
"What did you do when you were done with them?" the judge asked.
"I gave them to another fighter in return for R2,660 each. I was brainwashed. I thought the Yazidis were infidels, like Jews. That they were lower than Muslims and that what we were doing to them was OK."
As Islamic State continues to lose control in Iraq, more and militants are finding themselves captured by Kurdish Peshmerga and Iraqi security forces, who have taken much of the control on the ground. Many have surrendered.
According to journalists, including the BBC's Yollande Knell, who have stepped foot in the court, most cases involve young men accused of being members of Islamic State.
The number of detained extremists is currently unknown, but the court, made up of 12 judges, can hear up to 50 cases per day. One judge has reportedly signed arrest warrants for 6500 members of Islamic State.
Earlier this week, the court sentenced four militants to death in the first execution verdicts issued in Mosul since recapture.
"One of the militants was responsible for recruiting fighters for the group before capturing Mosul," a statement by the council's spokesman, Abdulstar Bayraqdar read.
"The other three were members of the Islamic Police."
In one case, heard by Ms Knell, a 21-year-old man "crumpled over and started crying" as he was found guilty by a panel of judges.
The court heard he had been picked up on the frontline of the battleground, and threw his weapon away just before he was detained.
The second defendant, another man in his young 20s, was more talkative.
He admitted joining Islamic State, telling the court, "I gave the loyalty oath to Abu Bakr al-Baghdadi," he explained, providing detail on how he had been trained by Islamic State to handle weapons and sharia law.
During the battle for Mosul, soldiers were faced with at least five suicide car bombers a day - many of them children - and drones strapped grenades. Islamic State was not going to let this city go without a fight.
Nearly one million Iraqis have fled the homes in Mosul since October, 2016, but since its recapture in July, its battered citizens are attempting to rebuild their fallen city, shaken to its core after years of airstrikes and shelling. Electricity and clean water supplies are already beginning to flow.
As of July 2017, More than 7000 Iraqi civilians had been killed in the conflict, while another 22,000 were wounded. Additionally, almost 1000 Iraqi security forces deaths had been noted.
