On August 8, nearly three years after the United States pulled out of Iraq, President Barack Obama ordered airstrikes to commence on Islamic State positions in northern Iraq, as the group’s fighters advanced towards the Kurdish capital of Erbil. For six weeks prior to the strikes the Islamic State made stunning gains within Iraq, effectively dismantling the border with Syria and defeating the Iraqi army with little in the way to stop them.

The lightning advances of the Islamic State across Syria and Iraq in June shocked the world. But it’s not just the group's military victories that have garnered attention — it’s also the pace with which its members have begun to carve out a viable state.

The Islamic State now governs its caliphate from the north central Syrian city of Raqqa, which was once a relatively westernized agricultural hub. As the State's power base, Raqqa is where it imposes its version of Sharia law throughout large swaths of Iraq and Syria. The "Hisbah" are the new Sharia police. In the latest episode of The Islamic State, VICE News joins them on their daily patrols during Ramadan, and witnesses how they check on shops and scrutinize produce, while at the same time ensuring their strict rules on women's appearances are adhered to. We are also taken to an Islamic State prison and speak with inmates accused of abusing drugs and selling alcohol. There we learn firsthand of the prisoners' punishments, and how they have since "rediscovered" their devotion to the Islamic faith since their incarceration — but are yet to be granted permission to declare their allegiance to the caliph, Abu Bakr al-Baghdadi.

Filmmaker Medyan Dairieh meets an Islamic State member from Belgium who works to indoctrinate some of the youngest members of the group. He also gains further insight into the minds of Islamic State fighters as they host celebrations and military parades featuring American tanks and APCs seized from the Iraqi army.

The Islamic State, a hardline Sunni jihadist group that formerly had ties to al Qaeda, has conquered large swathes of Iraq and Syria. Previously known as the Islamic State of Iraq and Syria (ISIS), the group has announced their intention to reestablish the caliphate and declared their leader, the shadowy Abu Bakr al-Baghdadi, as the caliph.
