Turkey's state-run television says Turkish warplanes have struck Islamic State group targets across the border in Syria.

TRT television says four jets took off from Diyarbakir air base in southeast Turkey and used missiles to hit the IS targets in the Syrian village of Havar. Havar is across the border from the Turkish border province of Kilis. TRT said the planes did not violate Syrian airspace.

The station did not cite a source for the report and there was no official confirmation of the airstrikes.

The report comes a day after IS militants fired from Syrian territory at a Turkish military outpost, killing one soldier and prompting Turkish retaliation that killed at least one IS militant.
