One person was killed and at least one other wounded Tuesday when three rockets fired from Syrian territory slammed into the Turkish border town of Kilis, reports said.
Two rockets hit empty areas but one caused casualties, Turkish media quoted Kilis mayor Hasan Kara as saying.
It was not immediately clear which force was in control of the area in northern Syria the rockets were fired from.
The attack comes after Turkish armed forces launched artillery strikes on repeated occasions in the last two weeks on Islamic State (IS) group positions in Syria.
A fragile ceasefire backed by Turkey has taken effect in Syria, but the deal does not apply to territory held by the IS group and Al-Qaida affiliate Al-Nusra Front.
From mid-February, Turkish artillery had also on successive days shelled targets of the Syrian Kurdish Democratic Union Party (PYD) inside Syria, with the military saying it was responding to incoming fire.
But Turkey has not shelled any positions held by Syrian Kurdish fighters inside Syria since the ceasefire was implemented on February 27.
Washington had urged Ankara to halt its fire on the PYD and its People's Protection Units (YPG) militia.
