The Shabak are a minority ethnic/religious group from Nineveh Province in northern Iraq. Much like the Kurds, they are a stateless people, so they tend to enjoy a degree of autonomy and have their own militias. By the looks of it, they’re putting them to good use.
In this video, the Shabak fighters show a group of dead ISIS mujaheddin whom they caught out in the open. Nineveh – the province where they live, has fallen to ISIS after the take over of Mosul so there’s plenty of mujaheddin around for them to kill.
A few thousand Shabak and Turkmen were reportedly trained to fight alongside the ISF – Iraqi Security Forces, against the Islamic State militants.
