An ivory-coloured rosary swings from the rear-view mirror of Abboud Seryan’s pickup truck as he speeds through Syria’s Raqa, inspecting the positions of fellow Christian fighters taking on the Islamic State group. Lively music blasts through the car speakers while the thin 23-year-old, wearing a military-style cap and a revolver tucked into his waist, waves to comrades in the western district of Al-Romaniya. IS was ousted from the neighbourhood earlier this month as part of the US-backed offensive to defeat the jihadists in their northern Syrian bastion. The ground assault is being carried out by the Syrian Democratic Forces, a majority Kurdish and Arab alliance, but dozens of Christians from the Syriac sect have also joined the fight. “We’re participating in the liberation of Raqa in the name of all Syrians. There’s no difference between Syriacs, Kurds, or Arabs. We’re all brothers,” Seryan says. The jihadists “blew up Raqa’s churches and forced Christians to convert to Islam. This is also why we’re participating in this battle.” Thousands of Syriac Christians once lived in Raqa alongside Armenians, Kurds and the city’s mainly Sunni Arab population, but many fled when ISIS overran the city in 2014. On June 29 of that year, ISIS declared the establishment of a self-styled “Islamic caliphate” straddling areas under its control in Syria and neighbouring Iraq. Christians could remain in Raqa if they paid a special tax called the jizya or converted to Islam — but many of them chose to flee. As the fightback against IS intensified the Syriac Military Council (SMC) — formed in 2013 to defend the community during Syria’s civil war — joined with the SDF. After a months-long operation to encircle Raqa, the SDF burst into the city on June 6 and are chipping away at jihadist-held districts, with help from heavy US-led coalition air strikes. Now the SMC’s fighters are battling jihadists on the frontline in Raqa, some proudly wearing their religion on their sleeves — literally. Many fighters have tattoos of rosaries inked around their wrists and the word “JESUS” printed down their forearms.
