On 9 June 2014, IS militants invaded Mosul in Iraq. All residents who didn't conform to their brand of Islam had to convert, pay a high tax or be killed. 120,000 Christians and other minorities fled and for the first time in 1,600 years there were no church services held in the city. Many families were left with nothing but the clothes on their backs, as IS militants stripped them of their belongings as they fled. Mariam, a gynaecologist who is a Christian, had to flee Mosul as the city fell. Her house was confiscated by IS and marked with the letter 'N' for Nasrani - a word used by IS to refer to Christians. Her precious library was emptied onto the street. Secret footage obtained by the BBC showed what life had become for those who stayed. Open Doors has been working through local churches and partners to provide relief to these refugees. In the past twelve months they have helped some 80,000 with immediate needs of water, food, medicine, hygiene kits and mattresses. They also work with the children, many of whom are deeply traumatised by their experiences.
