Turkish Foreign Minister Mevlüt Çavuşoğlu also lashed out at the US for not extraditing Fetullah Gulen, whom Ankara accuses of masterminding the 2016 coup bid, France 24 reported.

Çavuşoğlu said the accusations of spying and plotting against an employee of the US consulate in Istanbul were "serious" and that the outraged reaction from the US to the employee's arrest was "nonsense".
