HATAY, Turkey

Turkish security forces arrested five suspects Wednesday with links to a PKK terror attack in southern Hatay province, according to judicial sources.

The suspects were nabbed in Istanbul, Sanliurfa, Adiyaman and Diyarbakir provinces.

Iskenderun Chief Public Prosecutor's Office said an investigation was initiated after an explosion occurred in the district.

Police were chasing two PKK terrorists Monday in Iskenderun in Hatay when one detonated himself and the other was killed by forces.

In its more than 30-year terror campaign against Turkey, the PKK -- listed as a terrorist organization by Turkey, the US, and the EU -- has been responsible for the deaths of nearly 40,000 people, including women, children and infants.
