ANKARA, Turkey (AP) — Turkey's state-run news agency says unknown attackers have fired at traffic police in Turkey's mainly-Kurdish southeast, killing one officer and seriously wounding a second.

The attack Thursday comes amid a surge of violence in Turkey following a suicide bomb attack near Turkey's border with Syria which killed 32 people and has been blamed on militants linked to the Islamic State group.

The Anadolu Agency said the police officers were gunned in a street in Diyarbakir, the region's largest city. There was no immediate responsibility claim and an operation was launched to catch the assailants.

Kurdish militants on Wednesday claimed responsibility for the slaying of two other policemen who were found shot dead in their shared home and said the attack was carried out in retaliation to the suicide bombing.
