Turkish President Tayyip Erdogan slammed his French counterpart Emmanuel Macron on Saturday, saying he needed mental treatment over his attitude towards Muslims and Islam.
Earlier this month, Macron pledged to fight "Islamist separatism", which he said was threatening to take control in some Muslim communities around France, drawing a sharp rebuke from Erdogan.
"What is the problem of this person called Macron with Muslims and Islam? Macron needs treatment on a mental level," Erdogan said in a speech at a provincial congress of his AK Party in the central Turkish city of Kayseri.
"What else can be said to a head of state who does not understand freedom of belief and who behaves in this way to millions of people living in his country who are members of a different faith?" Erdogan added.
The Turkish president said on Oct. 6 after Macron's initial comments on "Islamist separatism", that the remarks were "a clear provocation" and showed the French leader's "impertinence".
Turkey and France are NATO members but have been at odds over issues including policies in Syria and Libya, maritime jurisdiction in the eastern Mediterranean and the conflict in Nagorno-Karabakh.
Erdogan and Macron discussed their disagreements in a phone call last month and agreed to improve ties and keep communication channels open.
