Snitch and get rewarded with sex slaves.

Aside from instilling fear among its members who are planning to defect by way of publicly torturing and executing defectors, the Islamic State (ISIS) has found another way to stop the depletion of its ranks.

As revealed in a confession made by a captured ISIS fighter, the jihadist group is now offering rewards to its members who snitch on fellow jihadis who are planning to defect or leave the group, Sun Online reports.

The ISIS fighter, identified as Abu Al-Mughaira Al-Muhajer, who was captured during the battle in the Syrian city of Aleppo, revealed that ISIS leaders are giving away sex slaves as rewards to loyal ISIS members who provide information about those who would leave its ranks.

In a recent interview on United Arab Emirates television and released in part on video by the Middle East Media Research Institute, Muhajer said he received three women—two Christians and a Yazidi—to use as his personal sex slaves after snitching in his own brother as a would-be deserter.

"After I informed on my brother who wanted to leave ISIS, I was rewarded with the slave girls – one [Yazidi] from Damascus and two [Christians] from Homs," he said.

He even described the women as having been treated poorly, saying they had been "beaten on their backs."

He likewise disclosed that ISIS leaders were buying sex slaves solely for the purpose of handing them out to their fighters.

In an earlier report on Sept. 20, Sun Online revealed that Christian and Yazidi women captured by ISIS militants are being sold at auctions in Saudi Arabia.

This was discovered when a jihadi was killed in fighting in the Iraqi town of Al-Shirqat, which was captured by the terror group in 2014.

Iraqi government forces recovered the ISIS fighter's mobile phone where images of one of the kidnapped girls and information on the sex slave trade were found.

"Our investigation officer was appalled at the set of images involving what we believe to be an Iraqi Yazidi (an ethnic minority in the region) woman taken as sex slave," an Iraqi military spokesman told Sun Online.

"Images were of the auction in Saudi Arabia of the woman and sexually explicit materials of the fighter and the woman in a hotel. Location data was observed on the image file as enabled by default on many smart phones," the official source added.

Saudi Arabia is part of the international coalition fighting ISIS, but wealthy Saudis have been accused of sponsoring the terror group for years.
