DIYARBAKIR, Turkey (AA) - Four additional suspects were arrested over an attack last week on a police station in southeast Turkey, police sources said on Tuesday.
One suspect remains at large, with investigations ongoing into the incident.
In Diyarbakir province on Wednesday, two PKK terrorists wearing masks targeted a police station in Yenisehir district with improvised explosives, injuring four.
In its more than 30-year terror campaign against Turkey, the PKK -- listed as a terrorist organization by Turkey, the U.S. and the EU -- has been responsible for the deaths of nearly 40,000 people.
