Turkey has vowed to take “legal, diplomatic actions” over a cartoon of President Recep Tayyip Erdogan in French magazine Charlie Hebdo.
The cartoon depicts Turkey’s president lifting the dress of a veiled woman.
State media say Turkish prosecutors have launched an official investigation into the satirical magazine.
Tensions between France and Turkey are high after President Emmanuel Macron pledged a tougher stance against radical Islam.
Mr Erdogan, who has also launched legal action against an anti-Islam MP in the Netherlands over a separate cartoon, has called on Turks to boycott French goods and said Mr Macron needed “mental checks”.
The dispute has reverberated across the world, spurring boycotts and protests against France in several Muslim-majority countries including Bangladesh, Kuwait, Jordan and Libya.
