The state-run Anadolu Agency says Turkish artillery fire has targeted the Islamic State group in Syria, killing 55 militants and destroying three vehicles and three rocket launchers.

The agency also said Turkish warplanes have struck positions of the outlawed Kurdistan Workers' Party, or PKK, in northern Iraq on Sunday.

The attacks come as Turkey is facing twin threats from the PKK and IS, which have carried out six major suicide attacks in the country since July.

The IS has fired rocket salvos almost daily against the Turkish border town of Kilis, which have killed 21 people and injured 70 others since mid-January, prompting the Turkish military to respond.

Anadolu said the military attacked IS targets north of Aleppo on Saturday. The AP couldn't independently verify the death toll.
