ANKARA, Jan. 8 (Xinhua) -- Turkey cannot accept the U.S. national security adviser's recent comments regarding the Syrian Kurdish militia, Turkish President Recep Tayyip Erdogan said Tuesday.

Speaking at his Justice and Development Party's (AKP) parliamentary group meeting, Erdogan said Ankara cannot accept the U.S. condition of ensuring the safety of the People's Protection Units (YPG) in Syria, reiterating the need to clear Syria of terrorists after U.S. forces leave the country.

Erdogan highlighted Turkey's determination to eliminate "terror corridor" in northern Syria, adding that Turkey made no distinction between terrorist groups.

U.S. National Security Adviser John Bolton arrived in Ankara late Monday to meet Turkish officials over safeguarding Kurdish fighters in Syria, who act as a U.S. vital ally against extreme groups.

However, Bolton reportedly departed Turkey at noon on Tuesday without meeting with Erdogan, in an apparent snub over disagreements about the Kurdish issue.
