"How can you claim that we support Daesh?… In Bashiqa alone we killed over Daesh 700 terrorists," Cavusoglu was quoted as saying by the Daily Sabah newspaper, responding to the comments of an Armenian representative at the NATO Parliamentary Assembly on Ankara's alleged support of the Islamists.
He added that Turkey was one of the most active fighters against Daesh, as well as one of the main terrorists' targets.
Daesh, a terrorist organization outlawed in Russia, the United States and a number of other states worldwide, took over vast swathes of Syria and Iraq in 2014.
Turkey sent troops across the border with Iraq late last year allegedly to train Sunni fighters at a base near the Daesh-held Iraqi town of Bashiqa. Ankara's move has been repeatedly criticized by Baghdad.
