The ISIS claims these hostages are Iraq’s Army POWs, some of them in their teens.
The narrator tells how they captured soldiers and covered their uniforms with civilian clothing. They forced their captives to chant, “long live the Islamic Nation,” as they pleaded for their lives.
They were lined up, face down in the dirt, and shot in the head, one after another.
The remaining hostages were escorted to a river. Each was shot in the head, their lifeless bodies tossed into the water, creating a pool of blood beneath them.
The ISIS celebrated, stating, “We will revenge and will return measure with measures…soon the Muslim will walk everywhere dignified with his head high. Here was the spark ignited in Iraq. It will arise Allah willing until they burn the armies of the cross in Dabiq (a prophetic battle in the last days of judgement.”
Walid Shoebat explains the ISIS’s intention on creating a blood river:
The reason for throwing victims in the river stems from Khalid bin Walid. When the Christians and Persians from Ullays turned down a peace offer by Khalid bin Al-Walid, the most respected Muslim general in Muslim history.
The story goes that when Khalid made a vow to Allah during the battle that if he defeated these resistors, he would make the canal that surrounded their village literally run with their blood. When the outcome was in Khalid’s favor, it actually took a day and a half to behead all of the captives. The obstacle for Khalid was that the ravine of blood coagulated and Khalid’s troops were forced to eventually release water into the canal in order that it would run red with the blood of the slain lest Khalid’s vow be left unfulfilled.
Some of Khalid’s men wanted to meticulously fulfill his wishes:
“Even if you were to kill all the population of the earth, their blood would still not run… Therefore send water over it, so that you may fulfill your oath. ”
Khalid had blocked the water from the canal. Now Khalid brought the water back, so that it flowed with spilled blood. Owing to this it has been called Blood Canal to this day.
