A U.S.-born ISIS fighter has been detained in northern Iraq, according to reports.
It was not immediately clear if the fighter — identified by local media and the Associated Press as Muhammad Jamal Amin — had been captured or surrendered.
Maj. Gen Feisal Helkani told the AP that Amin was carrying a large amount of cash and U.S. driver's license when he was taken into Peshmerga custody near the town of Sinjar.

The Kurdish news agency, Rudaw, said Amin is an American citizen born in Virginia to a Palestinian father and Iraqi mother. The news agency also posted pictures of what appeared to be a Virginia driver's license and U.S. bank cards.
The State Department said it was aware of reports that a U.S. citizen allegedly fighting for ISIS was in Peshmerga custody.
"We are in touch with Iraqi and Kurdish authorities to determine the veracity of these reports," it said in a statement.
Officials in Iraq and the Kurdistan Regional Government did not immediately respond to NBC News requests for comment.
A local Peshmerga commander said Amin entered Syria from Turkey two months ago and then traveled to Mosul, according to Rudaw.
U.S.-backed Kurdish Peshmerga forces have been battling to push back ISIS from areas of northern Iraq.
