The official said that the detainee identified as Sleiman Daoud al-Afari is an expert in chemical and biological weapons who once worked for Saddam Hussein's regime. During his interrogation, al-Afari has provided some important information regarding ISIS chemical weapons and operations. It is expected that al-Afari would be turned over to Kurdish forces by the US in the next few days.
Al-Afari was captured in February. He is said to be responsible for some of the potentially more deadly ISIS military operations. "He's a bad guy," according to one US official.
It is learned that al-Afari is the first ISIS operative captured by the US military's "Expeditionary Targeting Force", which is made up of two separate 50-man units of US special operations forces specifically targeting top ISIS officials in both Iraq and Syria. The units were formed in December 2015.
In October 2015, a raid was launched by Delta Force Commandos together with Kurdish forces to free more than 60 prisoners from an ISIS prison in northern Iraq. U.S. Army Master Sgt. Joshua Wheeler was killed in the assault in which the US forces had managed to kill twenty ISIS fighters and captured six. This raid took place before the formation of Expeditionary Targeting Force units.
