WATCH: A price list for Christian and Yazidi captured by ISIS
'The Spoils of War'
The Islamic State maintains a detailed price sheet for selling Christian and Yazidi girls as young as 1 year old as sex slaves in a document entitled "The Spoils of War" that suggests the terror group may be financing its activities by trafficking women to Turkish, Syrians, and Gulf Arabs, according to evidence submitted to the State Department.
Human rights activists say Western powers haven't done enough to stop the sexual enslavement and to investigate whether trafficking goes beyond ISIS soldiers to other countries, or to stop a systematic genocide targeting Christians in Syria and Yazidi minorities in Iraq.
Congress and the State Department earlier this year declared the slaughter a genocide for the first time.

'Could completely disappear'
"The fact that certain groups, Christians, Yazidis and others could completely disappear is something that is not being addressed at a level sufficient enough to keep these groups not flourishing, but surviving," Andrew T. Walther, a vice president of the Catholic Knights of Columbus, told Circa.

Walther's group, the world's largest Catholic fraternal organization, submitted a 400-page investigative report earlier this year to the State Department, accumulating evidence that it and the nonprofit In Defense of Christians gathered while aiding victims.
The report included a document written by Islamic State, or ISIS, that shows the terrorist organization suffered a decrease in sales of sex slaves and was adjusting the prices to regulate the sale of Christian women as far back as 2014.

Cartel price-fixing scheme
The ISIS document reads like a corporate cartel price-fixing scheme. It states the group has "received news that the demand in women and spoils of war market has been experiencing a significant decrease, which adversely affects the Islamic State of Iraq revenue and the financing of the Mujahideen assaults."
Therefore, the committee of the Treasury considered setting regulations and prices with regards to selling women and spoils of war," it adds.
Closer to extinction
On a trip last year to Iraq's Kurdistan region, Archbishop Bashar Warda, head of the Chaldean Catholic Church in Erbil, said the massacre of the Yazidis, pillaging of Christian communities and abduction of minority women and children has destroyed the ancient communities and pushed them closer to extinction.

Targeted for extermination
"Yazidis were really caught in the middle of the slaughtering campaign, a genocide," said Bishop Warda, whose church aids tens of thousands of Yazidi refugees.
"The Yazidis, poor, poor Yazidis, were really caught in a shock where they were kidnapped, sold on the market, subjected to various kinds of violence and death and most of the world did nothing to stop it," Warda said.
