An ISIS official captured by U.S. Special Operations Forces is a chemical weapons specialist and a "key operator" in terrorist and military operations, a senior defense official told NBC News
The detainee was identified as Sleiman Daoud al-Afari, an expert in chemical and biological weapons who formerly worked for Saddam Hussein's regime.
"He's a bad guy," according to one US official.
Under interrogation by the U.S. military, al-Afari has reportedly provided valuable information regarding ISIS chemical weapons and operations. The Americans are expected to turn al-Afari over to Kurdish forces by the end of this week.
