2 Brave Muslim women film how it is living as a woman under the ISIS controlled city of Raqqa, Syria

Two Syrian women took a hidden camera through the northern Syrian city of Raqqa to document their life under ISIS rule, knowing they faced execution should they be discovered, according to CNN Swedish affiliate Expressen TV, which commissioned the video.

Fully covered and wearing face veils, they shop, take a taxi and walk around neighborhoods, showing a deserted city with little traffic and some armed men walking about.

"Everyone's left," they say, because airstrikes on Raqqa have intensified. "Foreign ISIS fighters have set up checkpoints, taken the ID cards of Syrians and use them to flee to Turkey," the women say.

Five years after the start of the civil war in Syria, Raqqa -- the capital of ISIS' self-proclaimed caliphate -- has fundamentally changed. The war has claimed the lives of more than 250,000 people nationwide and displaced more than 10 million, according to the United Nations. ISIS captured Raqqa in 2013.

The video was taken in late winter, according to Expressen TV, and shows the rubble of what once was the Uwais al-Qarni shrine, important to both Sufis and Shia Muslims.

Passing by the Armenian Catholic Church of the Martyrs, distinctive by its geometric facade, one of the women notes ISIS has turned it into the Islamic police headquarters.
