The U.S. Deputy State Secretary reiterated Wednesday that the country is against the merging of areas known as Kurdish cantons in northern Syria, which are controlled by PKK's Syrian offshoot YPG.

Speaking in an interview for Turkish broadcaster NTV, Anthony Blinken said that the U.S.' position has been clear so far and will continue to remain that way.

Turkey and the U.S. have made important progress regarding the fight against said Daish terrorist group, Blinken stated. "We have come to a point that we have now seized the opportunity to remove this regional structure that calls itself a 'caliphate' both in Iraq and Syria. Only Mosul, Raqqa and Dabiq remains in Daish's so called caliphate. Therefore we will work on various plans to recapture these regions," Blinken said.

The plan to liberate Mosul from Daish, which was developed between the Iraqi central government and the Kurdistan Regional Government through months of coordination and cooperation, was also shared and discussed with Turkish authorities during the visit, Blinken said, adding that the PKK terror organization will not take part in the operation whatsoever.

Blinken noted that the U.S. wants to make sure that the fight against Daish is taking place in complete consultation and transparency with Turkey while all actions carried out in the process would not harm its national security.

Regarding the no-fly zone proposed by Turkey to prevent regime attacks from hampering humanitarian aid efforts and causing another refugee influx, Blinken said the latest actions by the regime and Russians in Aleppo made it hard for such proposals to come into being.

He also reiterated the U.S.' position on the extradition of Fethullah Gülen, the Pennsylvania-based cleric who is accused of managing the Gülenist Terror Group (FETÖ), remains the same. "For us this is completely a legal matter rather than a political one," Blinken said, adding that U.S. authorities are currently evaluating the information handed over by Turkish authorities.
