The fanatical jihadis are sending teams of trained killers into camps disguised as refugees to kidnap and kill vulnerable Christians. But refugees are terrified to report many of the killings in case they are targeted next, according to aid workers. The horrifying tactic emerged after one terrorist got cold feet and renounced jihad after witnessing Christians helping out other refugees within the camp.

He then revealed that he had been sent with an Islamist hit squad to eliminate Christians as part of the hate group's ideological drive to wipe the religion off the map. Express.co.uk has revealed how Christianity could disappear from the Middle East within five years as fanatical fundamentalists ramp up their campaign of persecution. An aid worker at a Unite4d Nations (UN) run camp in Jordan, who did not wish to be named for fear of reprisals, revealed that the jihadis are also kidnapping young refugee girls to sell on as sex slaves. He said: "The Muslim gangs come as refugees, but they have their agendas.

"They're like a mafia. People are even killed inside the camps, and the refugees are afraid to say if they saw somebody get killed. If you ask them, they'll say, 'I don't know, I was asleep.'" Britain has pledged to take 20,000 people in from such camps in the last five years.

But there are fears that hundreds of jihadis could disguise themselves as refugees in a bid to reach the UK, where they will plot terror attacks on our streets. The aid worker told the Christian Post: "The last time I went inside a camp, I had a policeman with me. "The camps are dangerous because they have IS, Iraqi militias and Syrian militias. It's another place for gangs. "They're killing inside the camps, and they're buying and selling ladies and even girls."

GETTY Christianity could disappear from the Middle East within five years as ISIS rampages

ISIS is believed to have executed thousands of Christians in Iraq and Syria who have refused to renounce their faith. When the terror group conquered the city of Mosul, in northern Iraq, it gave Christians 24 hours to either leave or face a gruesome death. But it appears that not all ISIS fighters are immune to the horrors the group's commanders order them to inflict.

The aid worker told how one terrorist from northern Syria, who was sent to a camp in Jordan to kill Christians, renounced his jihad after "witnessing the love of the Christians". He said: "He first saw how Islam brainwashed him about Christianity, and how that contrasted with the reality of what he saw in the Christians. "And we're talking about an area of Jordan that has three Salafist [a strict, fundamentalist branch of Sunni Islam] mosques. They raise up people to go and fight." The jihadi was reportedly so enthusiastic about his new religion he had to be hidden away to prevent him from being killed by ISIS militants furious at his conversion.
