Men caught in the grip of the Islamic State terror network cannot shave their beards, and must obey the decisions of a senior cleric over how to share their sex slaves.
Those guidelines were among a long list of rules found in documents uncovered in northern Iraqi towns freed from ISIS as U.S.-backed troops stormed the terror group's hub of Mosul. Reuters published details from the documents on Tuesday.
One pamphlet read, "Wearing beards is compulsory, shaving is prohibited." It defined a beard as "hair that grows on your face and your cheeks."
Another pamphlet, which included a question-and-answer section on women and girls held as ISIS captives, stated, "Non-Muslim women can be taken as concubines."
It reportedly added that terrorists could keep two sisters as concubines, but could have sex with only one of them. In addition, each woman could sleep with only one man.
Many of the documents included glossy photos with ISIS logos. Reuters reported that it could not independently verify that they originated from ISIS, but Iraqi troops said they were legitimate.
The papers also seemed to confirm the terror network banned most outside media. One poster told people in ISIS territory to destroy their satellite dishes in part "satellite channels show stories of love and naked women and inappropriate language."
Iraqi special forces paused their advance in an eastern district of Mosul on Wednesday to clear a neighborhood of any remaining ISIS fighters, as forces further to the south of the city took four small villages, military officials said.
In Mosul's easternmost Gogjali district, special forces could be seen going house to house while other troops searched the road for explosives and booby traps left behind by the jihadis driven out a day earlier.
Gen. Abdul-Ghani al-Asadi, the top counterterrorism forces commander, told reporters a curfew had been imposed in the neighborhood while gains there were being consolidated.
"We fear that Daesh militants could attack our forces or the town with mortars," he said, using the Arabic acronym for ISIS. "So for the safety of the families we ask them to stay inside their houses." He spoke in the town of Bartella, some 9 miles behind the front lines.
Brig. Gen. Haider Fadhil said that no advances were planned while high humidity and clouds obscured the view of aircraft and drones -- a key component to the operations provided by the U.S.-led air campaign.
