An Islamic State (IS) militant who helped imprison and brutalize American hostage Kayla Mueller will not be charged in the United States, the White House announced August 7.
The militant known as Umm Sayyaf cooperated with American military interrogators after she was captured in Syria during a May U.S. Special Operations raid.
She is an Iraqi citizen and will be prosecuted by Kurdish authorities in Iraq, White House spokesman Josh Earnest said.
"While we obviously can't guarantee a particular result, we do have a firm belief that she will be held accountable for her crimes," Earnest said.
Sayyaf, who is already in Kurdish custody, was the wife of an Islamic State financier known as Abu Sayyaf, who was killed during the Delta Force raid three months ago.
Documents seized at the raid site, and hours of conversations with Sayyaf, have provided American officials with some of their best intelligence to date on IS, U.S. officials said.
Mueller and her Syrian boyfriend were taken hostage in August 2013. The boyfriend was later released. In February, IS announced she had been killed in a Jordanian air strike.
