ANKARA, Jan. 7 (Xinhua) -- U.S. National Security Adviser John Bolton and his delegation arrived in Ankara on Monday to discuss security arrangement as the U.S. troops withdraw from Syria.

Talks between U.S. and Turkish officials scheduled for Tuesday are expected to focus on the coordination of regional security following U.S. troops pullout from Syria, the roadmap for Syria's Manbij, and the fight against Islamic State (IS) and other terror groups, reported Anadolu Agency.

The sale of U.S. Patriot air defense systems and extradition of Fethullah Gulen, U.S.-based preacher, are among the topics as well.

Monday's visit comes a day after Bolton said the U.S. will not withdraw troops from Syria unless the Turkish government guarantees it won't attack Kurdish fighters.

Turkish Defense Minister Hulusi Akar responded on Monday, saying that Turkey's fight isn't against Kurds but against the People's Protection Units (YPG) and IS group.

Ankara sees the YPG as the Syrian affiliate of the Kurdistan Workers' Party (PKK), listed as a terrorist organization by Turkey. However, the United States has supported the YPG to combat the IS in Syria.

The U.S. delegation is due to leave on Tuesday.
