The top female ISIS member who has been captured claims she has been cooperating with the CIA to help them track down terror kingpin Abu Bakr al-Baghdadi — though he remains at large despite her purported assistance.

Nisrine Assad Ibrahim, better known by her nom de guerre, Umm Sayyaf, has helped both the CIA and Kurdish intelligence officers learn about Baghdadi’s movements, hideouts and networks, the Guardian reported.

The woman was captured in a Delta Force raid in Syria four years ago that killed her husband, then the ISIS oil minister.

But the 29-year-old is a controversial figure who has been accused of involvement in some of the terror group’s most hideous crimes, including the enslavement of captured US aid worker Kayla Mueller and several Yazidi women and girls, who were raped by senior ISIS leaders, the UK paper reported.

She was sentenced to death by a court in Erbil, Iraq, and spoke to the Guardian, partly through a translator, at a prison in the city.

In February 2016, she identified a house in Mosul in which Baghdadi was believed to have been staying.

“I told them where the house was,” she said. “I knew he’d been there because it was one of the houses that was provided for him, and one of the places he liked the most.”

But US officials decided not to strike the house based on her intelligence alone, though they later acknowledged that he was likely there.

Despite her purported cooperation, she is unlikely to have her sentence commuted, Kurdish authorities said.
