A captured ISIS terrorist has told in chilling detail of the mass executions the terrorist group carried out during their barbaric raids.

Amar Hussein says he reads the Koran all day in his tiny jail cell to become a better person, yet he shows little remorse for the 200 women he raped as he pillaged Iraqi villages, Daily Mail reported.

According to him, local Islamic State commanders, gave him and others a green light to rape as many Yazidi and other women as they wanted.

“Young men need this,” Hussein said in an interview after a Kurdish counter-terrorism agent removed a black hood from his head.

Hussein said he also killed about 500 people since joining Islamic State in 2013.

“We shot whoever we needed to shoot and beheaded whoever we needed to beheaded,”  Hussein said.

He recalled how emirs trained him to kill, which was difficult at first when one person was brought for a practice kill. It became easier day by day.

“Seven, eight, ten at a time. Thirty or 40 people. We would take them in desert and kill them. I would sit them down, put a blindfold on them and fire a bullet into their heads,' he said. 'It was normal,”  Hussein said.

Hussein, now 21, began his career as an Islamic militant began when he was just 14.
