Iraq, Feb 16 (ANI): Thousands of foreigners have flocked to Iraq and Syria, most of them to join Islamic State, but there are few who came to fight on the other side by joining a small Christian militia. The militia they have joined is called Dwekh Nawsha - meaning self sacrifice in the ancient Aramaic language still spoken by Assyrian Christians, who consider themselves the indigenous people of Iraq. Dwekh Nawsha operates alongside Kurdish peshmerga forces to protect a cluster of Christian villages on the front line. Twenty-eight year old Brett is one of the volunteers who came from overseas, a US army veteran who recently returned to Iraq to fight Islamic State in what he sees as a wider war between good and evil. Brett is the only one of the foreign volunteers to have engaged in fighting so far. The others only recently arrived, and were turned back from the front line on Friday by Kurdish security services because they did not have necessary approval from the authorities.
