This was the second such initiative by the Turkish Army in the past two days. On April 27, according to Turkish sources, 13 ISIL militants were killed when Turkish artillery units shelled a building in the Duwaibik region to the north of Aleppo. The building used by ISIL militants collapsed, killing 13 militants inside and injuring another seven. Around 150 Katyusha rocket projectiles stored on the ground floor of the building were also destroyed. The same day Turkish artillery units also shelled two missile launchers and killed 11 ISIL militants. On April 28, five mortar shells targeting a border military post in the Karkamış district of the southeastern province of Gaziantep were fired by the ISIL. 11 ISIL militants were killed in Turkish artillery shellings following the attack according to Turkish sources. On April 29, two rocket projectiles fired by the ISIL hit the border province of Kilis in Turkey. On January 1, a gunman entered a nightclub in Istanbul and killed 39 people. On 6 February, about 820 ISIL suspects, most of them foreign nationals, were arrested in at least 29 provinces, including capital Ankara and southeastern provinces during the past week, Anadolu news agency reported. On November 4, 2019, Turkish communications director Fahrettin Altun stated that Rasmiya Awad, Baghdadi's lesser-known older sister, had been captured. According to Reuters, citing Turkish officials, Awad was captured in a raid on a shipping container in the Turkish-controlled Syrian border town of Azaz and that Turkish authorities were interrogating her husband and daughter-in-law who were also detained. When captured, she was also accompanied by five children. "We hope to gather a trove of intelligence from Baghdadi’s sister on the inner workings of Isis," Altun stated. Little independent information is available on Baghdadi’s sister and Reuters was not immediately able to verify if the captured individual was her.
