The 15 year old says ISIS would give fighters a drug that causes you to lose your mind, making you willing to strap on a suicide vest.
SYRIA - In the basement of a prison in northern Syria, men accused of being ISIS terrorists were led in one by one. The guards holding them are part of a Kurdish group fighting against the Islamic extremists and don't want to be identified.
15-year-old Kareem Mufleh freely admits that he fought with ISIS
They captured my village and gave me a choice," he said. "Either join ISIS, or be beheaded."
ISIS has embarked on a reign of fear. Mufleh told us he was a witness to massacres when ISIS seized villages in Syria.
"I even saw them kill a woman because her wedding dress showed her neck and bare arms," Mufleh said. He claims that ISIS gave him the anti-anxiety drug Zolam before he went in to battle. "That drug makes you lose your mind," he said. "If they give you a suicide belt and tell you to blow yourself up, you'll do it."
