Islamic State militants have turned Christian churches into torture chambers.

According to the Jerusalem Post, Isis have been forcing church-goers to convert to Islam, in a bid to 'wipe out Christianity.'

Christians were reportedly being held captive in make-shift torture chambers set up in raided churches in Qaraqosh, Iraq.

The Jihadists have stripped the churches of their ancient relics and artefacts, to be smuggled to Western collectors to help fund their terrorist activity.

The extremist organisation have made £23 million from the sale of stolen artefacts in Nabaq, Syria, according to the Christian Post.

A source said: "This is why they are crucifying Christians — which includes children — destroying churches and selling artefacts.

"The reality is, this group will stop at practically nothing to raise funds for its terrorist mission."

The news comes as it has been revealed that militants captured a Jordanian pilot after his warplane crashed while conducting airstrikes over Syria.

His father, Yusuf al-Kasasbeh, said the family had been informed of Lt Al-Kasasbeh's capture by the head of the Jordanian air force.

He appealed to Isis' leaders for compassion saying: "May Allah plant mercy in your hearts and may you release my son."

Canon Andrew White, the vicar of the only Anglican church in Iraq, has warned Christians that the end of the religion in the country appears "very near".
