(KUNA) -- Turkish authorities have aborted planned bombing of a building housing offices for the central intelligence in the southeast of the country. "Khabar Turk" website reported on Friday that up to 495 kg of explosives were set to go off and blow up the building in the province of Shirnak. But police arrested two members of the Workers Party of Kurdistan (the PKK) while the pair were trying to plant the explosives. The PKK, a group based in the southeast of the country, advocates establishing a separate Kurdish entity.
