His comments came as Nato envoys met in Brussels to discuss the crisis in Syria and Iraq in a special session requested by Turkey.
“It is not possible for us to continue the peace process with those who threaten our national unity and brotherhood,” Erdoğan told a news conference in Ankara before departing for an official visit to China.
The Turkish air force has bombed camps in northern Iraq of the Kurdistan Workers’ party (PKK). The PKK said the air strikes rendered the peace process meaningless, but had stopped short of formally pulling out.
Opening the specially convened meeting in Brussels, Nato’s secretary general, Jens Stoltenberg, expressed solidarity with Turkey in its fight against terrorism. Stoltenberg told the 28-member alliance: “Nato is following developments very closely. And we stand in strong solidarity with our ally Turkey.”
Stoltenberg said it was right to hold the meeting since there is instability on Turkey’s border and Nato’s southeastern border.
It was easy for Stoltenberg to express support for Turkey joining the fight againstIslamic State. More problematic for the US and other members of the alliance is Turkey linking the fight against terrorism to include the PKK.
The difficulty for the US and other allies is that the fight against Kurdish separatists is largely seen as a domestic problem. A further – and bigger – reservation is that the PKK is one of the few armed groups in the region putting up a fight against Isis.
