Turkey's president has strongly rejected US calls for his country to protect Kurdish fighters in Syria.
President Recep Tayyip Erdogan said such statements made by US National Security Adviser John Bolton at the weekend were "unacceptable".
Mr Bolton was in Ankara to seek guarantees that a Kurdish militia battling the Islamic State group would be safe after US troops pulled out.
Turkey regards the People's Protection Units (YPG) as a terrorist group.
Mr Erdogan told MPs from his governing Justice and Development Party on Tuesday that he could not "accept and swallow" Mr Bolton's message.
