Eight civilians were killed and 35 wounded when the YPG militants launched a mortar and rocket attack on Turkey's Syrian border town of Nusaybin, the governor's office in the southeastern province of Mardin said on Friday.
The wounded were taken to hospitals in the region, the governor's office said.
Turkey on Friday stepped up its air and artillery strikes on the bloody-minded PKK's Syrian branch YPG in northeast Syria, focusing mainly on an area further west along the border region.
