Islamic State (Isis) have released a list of seven rules which all Christians living in Syrian city Raqqa must obey.
The statement opens with a quote from the Quran, which reads: "Fight those who do not believe in Allah, nor in the latter day, nor do they prohibit what Allah and His Apostle have prohibited, nor follow the religion of truth, out of those who have been given the Book, until they pay the tax in acknowledgement of superiority and they are in a state of subjection."
It goes on to declare that Abu Bakr al-Baghdadi, the self-styled caliph of Islamic State, had given safety to Christians, promising to protect "their selves, children, money and churches."
The promised safeguard comes with a list of seven clear rules, forbidding public worship and treachery against IS.
Under IS, Christians in Raqqa are no longer allowed to construct churches in their villages or even repair any damaged churches.
They are also banned from publicly showing their crosses in Muslim areas, or in their own market places. All acts of worship must be carried out with minimal noise as IS have forbidden Christians to "raise their voices when praying or in other acts of worship."
The statement specifically states that "Muslims do not hear the recitation of their books out loud", effectively banning any Christians from openly reading the Bible or singing psalms. Likewise, all acts of worship must be carried out inside a church and under no circumstances should acts of worship be performed in public.
Christians have also been ordered not to prevent any of their fellow Christians from converting to Islam and that they should never "make a mockery" of Islam and Muslims.
A clear warning has also been made to Christians living in Raqqa. IS have declared that it is illegal, under pain of death, for Christians to "carry out any actions of enmity to the Islamic State such as helping air strikes locate their positions."
IS recently executed three men in Raqqa, for being found guilty of placing beacons near strategic buildings and aiding coalition air strikes.
