An ISIS militant, who had pretended to be a refugee in order to kill people, converted to Christianity after seeing the "love of Christians" at the camps, according to Christian Aid Mission.

An ISIS fighter from northern Syria, veiled as a refugee, arrived at a Jordanian camp with the intention of killing Christian workers, but he abandoned his plans after hearing the Gospel and "witnessing the love of Christians."

"He first saw how Islam brainwashed him about Christianity, and how that contrasted with the reality of what he saw in the Christians," the ministry director that could not be named said. "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 militant convert was so excited about his new found faith that the director had to "calm him down" to dispel threats he began receiving from other jihadists who wanted to kill him after his conversion.

The situation inside some UN-operated refugee camps in Jordan are often violent, according to the director; ISIS fighters are disguising themselves as refugees in order to kill people and sell girls.

"The Muslim gangs come as refugees, but they have agendas. They're like 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.'"

"The last time I went inside a camp, I had a policeman with me," he added. "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."
