A delegation of members of the US House of Representatives urged Ankara to abandon the purchase of Russian S-400 air defense missile systems, Hurriyet Daily reported.

“A three-member delegation headed by Congressman Michael Turner, a member of NATO Parliamentarian Assembly, first visited İncirlik Airbase in southern Adana province. The delegation later met with Turkish parliamentarians and discussed the issues of Turkey’s purchase of Russian S-400 systems and delivery of F-35 fighter jets to Turkey,” the source noted.

According to Hurriyet, during the talks with Turkish parliamentarians, the American side urged to abandon procurement of S-400 systems, in order to guarantee the delivery of F-35.

Ankara, in its turn, insisted on continuing cooperation to fight the supporters of the preacher Fethullah Gulen, whom the Turkish authorities accused of organizing a coup attempt in July 2016.
