There are new reports that claim Christians living in Iraq are being forced to leave their homeland after constant persecution by the Islamic State in Iraq and Syria (aka ISIS), where the Muslim group recently marked Christian homes with the letter "N" for Nazarene.

In addition, the ISIS previously issued an ultimatum on Friday that Iraqi Christians must convert to Islam, pay extra taxes to Islamic Sharia courts by June 19 at noon (5am EST) or face "death by the sword," according to a CNN report.

Furthermore, ISIS also ordered Christians to appear in a meeting that took place on July 17 to discuss their standing in the country.

"We were so afraid to go," said research expert Duraid Hikmat according to an Assist News report.

As a result, many Iraqi Christians fled their nation over the weekend in order to avoid certain death after it was revealed the ISIS had reportedly killed 1,531 people in June alone, which brings the death total to at least 5,576 people according to a report by the United Nations mission in Iraq and the United Nations human rights office in Geneva, Switzerland.

"They told us, 'You to leave all of your money, gold, jewelry and go out with only the clothes on you,'" said Wadie Salim told CNN.

According to CNN, the Mosul Governor Salman al-Farisi said Christians must pay 550,000 Iraqi dinar (worth approximately $470 in the US) if they continue to live in the Iraqi city.

"We are not thinking of going back to Mosul, we have left homes with our memories," said Omar to New York Times, who recently fled to Bartella, Iraq, "It is a sad time for Christians."

Additionally, the ISIS group recently killed at least 270 people in a gas field massacre in Homs, Syria on Thursday. Among the victims, 90 employees who worked at the station were killed and are still reportedly missing.

"Being a Turkman, a Shabak, a Yazidi or a Christian in ISIS territory can cost you your livelihood, your liberty, or even your life," said Human Rights Watch Middle East Director Sarah Leah Whitson said in a statement released on Saturday from Duhok in Iraqi Kurdistan, according to CNN.
