Turkey, US in deadlock over two major issues

Turkey and the United States have become ensconced in a deadlock over two major issues, Turkey's demand for the extradition of U.S.-based Islamic preacher Fethullah Gülen, whom the government accuses of staging the failed July 15 coup, and the approach to Syrian Kurdish fighters.

Erdoğan, who is attending meetings at the United Nations, also accused the United States of supplying more weapons to the Syrian Kurdish Democratic Union Party (PYD) and its military wing, the People's Protection Unit (YPG), in northern Syria this week.
