Erdogan pledges to fight back as PKK steps up attacks

Violence escalated following Ankara's air bombardment targeting Kurdish militants

President Recep Tayyip Erdogan on Monday vowed to do "whatever necessary" in Turkey's fight against Kurdish militants, with no end in sight to a two-week cycle of violence.

Ankara is waging a two-pronged cross border "anti-terror" offensive against Islamic State militants in Syria and rebels from the Kurdistan Workers Party, also known as PKK, in northern Iraq, after a wave of attacks in the country.
