The sister of former Islamic State group (IS) leader Abu Bakr al-Baghdadi has been captured in northern Syria, Turkish officials say.
The 65-year-old, named as Rasmiya Awad, was detained in a raid on Monday near the town of Azaz, officials said.
Turkish officials, cited by several media outlets, said the arrest could yield valuable intelligence about IS.
One Turkish official told Reuters news agency the arrest of Baghdadi’s older sister may help shed light on “the inner workings” of IS.
Turkish President Recep Tayyip Erdogan’s communications director hailed the arrest as “another example of the success of our counter-terrorism operations”.
Little is known about Baghdadi’s sister and the BBC has not yet been able to independently verify the identity of the arrested woman.
Baghdadi had several brothers and sisters, although it is not clear if they are all still alive, the New York Times reports.
