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.
“We hope to gather a trove of intelligence from Baghdadi’s sister on the inner workings of ISIS,” he added.
The arrest was reportedly made in Aleppo province, which is controlled by Turkey after it launched an offensive in the area last month.
Ms Awad was found in a trailer, where she was living with her husband, daughter-in-law and five children, a told by Turkish official, adding that she was being interrogated on suspicion of involvement with an extremist group.
Turkish officials, cited by multiple media outlets, said the arrest could yield valuable intelligence about IS.
According to a Turkish official the arrest of Baghdadi’s older sister may help shed light on “the inner workings of ISIS”.
Baghdadi had five brothers and several sisters, although it is not clear if they are all still alive, the New York Times reports.
President Trump announced the death of Baghdadi at a press conference at the White House on 27 October.
Baghdadi detonated his suicide vest after fleeing into a tunnel during a US raid on his hideout in Idlib province, Mr Trump said.
