Islamic State of Iraq and Syria (ISIS), the Islamist militant group, has reportedly been harvesting organs as well as blood from its healthy prisoners, according to an escaped hostage. 

In a statement released by escaped captive Abo Rida to an anti-ISIS website RBSS, ISIS not only tortures prisoners but also uses them as blood donors. 

He relays that healthy prisoners are lucky because they are given special care. He says, "Some of the prisoners were having a strong bodies and healthy, they weren't get tortured, but they were taking special care of them."

He continues, "Because ISIS was using them as a blood bank to withdraw blood when they need it for his injured members."

Aside from getting blood from its prisoners, various body organs are also taken from healthy prisoners to be given to ISIS terrorists in need.

"There were some of the surgeries that ISIS did and moved organs such as kidneys and corneas from the prisoners to the members arguing that the fate of these prisoners inevitable death and the members are deserving those organs more than their owners," he said. 

Abo Rida, who was held prisoner by ISIS inside the state security building now being used by ISIS as a prison, escaped following an attack planned to eliminate the terrorists in the area. 

After four months of being held captive, He recalls the incident saying, "I remember that day very well... at the beginning we heard several explosions and then it hit the prison... the place was full of dust... we tried to exploit the situation to escape from prison and we ran out... only four people could escape including me."

News about ISIS organ harvesting and bloodletting has allegedly been rampant with the ISIS militants. It has also been confirmed by other captives as told by Mail Online saying that doctors would usually look for blood following explosions.
