“The conditions for maintaining the ceasefire… have been eliminated,” the People’s Defence Forces (HPG), the military wing of the Kurdistan Workers Party (PKK) said in a statement.
It denounced an “aggression of war” by Turkey and vowed “resistance.”
“Faced by these aggressions, we have the right to defend ourselves and to resist,” it said. “The defence of our freedoms and democracy is the duty that you have in front of you,” the group added.
It described the bombings of the targets in northern Iraq as the “most serious military and political error” by President Recep Tayyip Erdogan and the ruling party.
The two the sides had until now largely observed a fragile ceasefire since 2013, but the fighting has now thrown the entire process to make peace with the PKK into doubt.
The PKK has for decades waged a deadly insurgency in the southeast of Turkey for self-rule that has claimed tens of thousands of lives.
The HPG statement meanwhile said that one of the PKK fighters in northern Iraq — named as Onder Aslan — had been killed in the air strikes and three of its “guerillas” wounded.
The raids were the fiercest launched by Turkey on the group’s bases in Iraq since August 2011 when PKK targets in northern Iraq were pounded by Turkish jets in almost a week of air strikes.
