Samir Afif Ammar was sitting in a small café in Deir Al-Zor, a city in northeastern Syria on the Euphrates, when a man he had never met named "Abu Omar" sparked a conversation. Abu Omar said he could give him work in an Iraqi oil field and he promised him a good salary. It was January 2009, and Abu Omar would soon thereafter smuggle a then 19 year-old Samir across the border to Iraq. Samir spent two weeks in Iraq, and as recounts, "I can't remember the rest."
