How does government’s power affect the news frames of terrorism? This thesis seeks to answer this question in the case of PKK attacks’ presentations in media in Turkey. Current study explores the news frames during two periods in contemporary Turkish politics; the interim government period of June 7th 2015- November 1st 2015, and, the single party government period upon the November 1st 2015 general elections in Turkey. The study asks two initial questions; how the PKK attacks are framed in the periods of interim government and single party government in Turkey; and how news frames in two periods of government differ from each other. The purpose has been exploring the effects of the single party government’s consolidation of power on news frames. To answer the research questions posed, I conducted a news frame analysis of 1068 news articles published on four PKK attacks, two of which occurred in the interim government period and the other two in the single party government period. The news articles are gathered from three different newspapers published in Turkey. The results indicate significant differences in frame usage between the two time periods. As government consolidated its monopoly on political power in Turkey, news frames displayed an increasingly militaristic approach to the PKK attacks, presenting the continuation of the military operations as the only solution to terrorism. The responsibility of the PKK attacks was attributed to the official authorities in the interim government period whereas criticism of official authorities and policies significantly decreased in the single party government period. An increase in conspiracy theories portraying unidentified dark powers as responsible for PKK terrorism prevails in the single party government period. All findings are discussed in terms of their contributions to the political communication literature and terrorism discourses.
