Justice Minister Bekir Bozdağ on Tuesday conveyed Turkey's expectations on the extradition of FETÖ leader Fetullah Gülen to U.S. Attorney General Jeff Sessions.

During the phone call between the two officials which lasted about 30 minutes, Bozdağ congratulated Sessions on his appointment as Attorney General.

In February, Bozdağ sent a letter to Sessions to request the extradition of fugitive leader, saying the extradition process remains the most important issue between the two countries.

Turkish-American relations were severely strained during the Obama administration's open support for the PKK's Syrian offshoot, the People's Protection Units (YPG), and its reluctance to process Turkey's extradition request for the FETÖ leader. However, bilateral relations appear to have entered a more productive and collaborative phase since Donald Trump assumed office.

Under a 1979 treaty between the U.S. and Turkey, the former is obliged to temporarily detain any suspect and meet extradition requests upon the fulfillment of legal submittal requirements. Turkey submitted official evidence against Gülen and his network to the U.S. in October of last year.
