Turkish President Recep Tayyip Erdogan on Friday said he was "extremely saddened" by France's position after Paris offered to mediate with the Syrian Democratic Forces dominated by a Kurdish militia deemed a terrorist group by Ankara.

French President Emmanuel Macron has suggested that Turkey should renounce its ambition of joining the EU and settle instead for a looser "partnership" after talks with visiting Turkish leader Recep Tayyip Erdogan.
