ISIS' female militants have tortured a woman with a medieval-inspired and spiked clamp for breastfeeding her baby in public. The all-female group, known as the Al Khansa brigade, are using a torture device called the "biter" to ensure everyone strictly observes the Sharia law in the ISIS-held town of Raqqa.

The female members of ISIS are believed to include British women serve as "religious police" and torturing those who violate the law. The giant device they use has two iron jaws covered with spikes. It is clamped around the victim's chest to cause severe pain, according to The Mirror.

Residents who witnessed the incident said ISIS' Al Khansa force punished the woman with the device after she was found nursing her child in the bus station in Raqqa. Since ISIS has declared the establishment of its own "caliphate" in June, around 1,880 people have been murdered in battle and mass killings. Previous reports said at least 1,177 civilians have been killed in over the past six months including eight women and two children.

One 24-year-old woman was arrested while she was in the market for wearing a see-through Niqab that did not meet the Sharia requirement. Brave Batol said in a Mirror report that ISIS arrested her and placed her inside the torture chamber. She revealed ISIS made her choose between a biter and a whip as her punishment. Since she didn't know what a biter was and thought it was a reduced sentence, she chose that instead of the whip.

To Batol's horror, she saw the militants bring out a sharp object with a lot of "teeth" and placed it on her chest before clamping down. She screamed from the immense pain. ISIS took her to the hospital for treatment.

She described her experience and said she felt her femininity was "destroyed" completely. Batol added that there were many women in the torture chamber.

Meanwhile, in an attempt to fight ISIS' ideology, the Pentagon has convened a secret group to analyse what makes ISIS so attractive to supporters. According to New York Times, Maj. Gen. Michael Nagata, American Special Operations forces in the Middle East, had sought help of experts in understanding ISIS. In a confidential minutes of a conference call to experts, Nagata said they cannot beat ISIS unless they understand the movement.

The internal conference calls had produced one of the expert panel's initial observations that ISIS has the ability to control populations using "psychological tactics" like terrorism, religious and sectarian rules and economic controls. ISIS' radical views continue to attract foreign fighters who flock to Iraq and Syria every month to join the group, according to U.S. intelligence officials.
