9 out of 10 countries where Christians face the worst persecution have a Muslim-majority population, Open Door's World Watch List 2015 has revealed.
The list, an annual survey of "religious liberty conditions" for Christians worldwide, named North Korea the worst country for persecution for the 13th year in a row, stating that the "god-like" worship of Kim Jong-Un made it "virtually impossible" for Christians to exist.
According to Open Doors, it is illegal to be Christian in North Korea, and if discovered, Christians are sent to labour camps or killed.
Following the Communist dictatorship-led country were Somalia, Iraq and Syria, all which have a large majority of their population made up of Muslims.
Over the past year, reports of Christians being targeted by Islamic extremist groups Islamic State and al-Shabaab have soared.
Open Doors also reported that the main cause for persecution observed was "Islamic extremism," from which 100 million Christians suffer under.
"Christian persecution is any hostility experienced from the world as a result of one's identification as a Christian," the persecution watchdogs explained.
"Beatings, physical torture, confinement, isolation, rape, severe punishment, imprisonment, slavery, discrimination in education and employment, and even death are just a few examples of the persecution they experience on a daily basis."
The top ten rounded up with Afghanistan, Sudan, Iran, Pakistan, Eritrea and Nigeria making the list.
