Turkish President Tayyip Erdogan announced that he had captured the wife of Abu Bakr al-Baghdadi, the supreme leader of IS, who was killed last week.

"The US says Baghdadi committed suicide in a tunnel. They have made a strong propaganda about this," Erdogan said in a speech at Ankara University on November 6. "But today, I announce for the first time that we have captured his wife and we did not make a fuss like them. We even caught his sister and brother-in-law in Syria."

Earlier, a senior Turkish official said they arrested Baghdadi's sister, Rasmiya Awad, 65, with her husband, daughter-in-law and five children in the town of Azaz in northwestern Syria on November 4.

ISIS leader Abu Bakr al-Baghdadi was killed by US special forces during a raid operation in Idlib province on October 26. Baghdadi detonated a suicide belt in the bunker with his two children when he was cornered. The Islamic State later confirmed his death and announced the new leader, Abi Ibrahim al-Hashimi al-Qurashi.
