ANKARA, Jan. 23 (Xinhua) -- A U.S. delegation including high-ranking officials arrived in Ankara on Monday to discuss bilateral issues and Turkey's military operation against U.S.-backed Kurdish militia in Syria, state-run Anadolu Agency reported Tuesday.

The U.S. delegation, led by Deputy Assistant Secretary for European and Eurasian Affairs Jonathan Cohen, will meet with Turkish officials from the foreign ministry on Tuesday.

The agenda of the meeting includes Turkey's "Olive Branch" operation in Syria, the bilateral visa crisis and the ongoing investigations of U.S. consular staff.

The U.S. delegation will also hold a meeting with officials of the Turkish General Staff.

The Turkish military and allied Free Syrian Army (FSA) rebels launched "Operation Olive Branch" on Saturday, opening a new front in Syria's seven-year-long war.
