ISTANBUL (Reuters) - Syrian Kurdish PYD forces sprayed a Turkish border post with gunfire late on Tuesday, wounding one soldier, and Turkey responded with artillery fire, private broadcaster CNN Turk said

The gunfire came from Afrin province in northwest Syria, it added. No further information was immediately available.

Turkey views the PYD and its armed YPG affiliate as offshoots of the outlawed Kurdistan Workers Party (PKK), which has fought a decades-long insurgency in Turkey and is designated a terrorist group by Ankara, the United States and the European Union.
