The bombardment by Syrian Kurdish Democratic Union Party (PYD) forces hit the post in Kilis province and the Turkish military responded with shellfire, Yilmaz told a parliamentary budget meeting. He did not say how many bombs landed.

“When a strike hits our border within the rules of engagement it will be responded to in a dissuasive way,” he said.

There were no casualties on the Turkish side of the frontier, the minister added.

Turkish troops have shelled PYD positions around Azaz in northern Syria since Saturday in response to artillery strikes on Turkey.

The PYD is the Syrian affiliate of the PKK, which is listed as a terror group by Turkey, the U.S. and EU and has waged war against the Turkish state since 1984.

Azaz -- six kilometers (four miles) from the Turkish border -- has been the scene of recent heavy fighting as the PYD has advanced during a Russian-backed Syrian government offensive against opposition forces.
