The Kaka'i are a secretive religious minority in Iraq who usually avoid the cameras.

Their persecution has forced them to keep their beliefs and rituals a secret; once numbering in their millions in Iraq, there are now just 200,000.

They have been persecuted by extremists in the region who consider them to be infidels, such as ISIS and al-Qaeda.

The Kaka'i have also faced discrimination from the Shia Muslim-led paramilitary Popular Mobilisation force since the central government retook control of Kirkuk province from Kurdish forces in 2017.

They are finally revealing their lives to the international community in an attempt to thwart the risk of genocide.
