Prosecutors have launched an investigation into the proclamation of a Kurdish autonomy in the country's largely Kurdish southeast, according to AP. The prosecutor's office in Diyarbakir, the largest city in the southeast, announced Friday that it is examining the declaration, which the government sees as a threat to national unity. An umbrella group that includes Turkey's Kurdish party proclaimed Kurdish autonomy in Diyarbakir on Thursday, hours after a clash left 13 soldiers and seven Kurdish guerillas dead in the region. The deaths of the soldiers and the declaration of autonomy have dramatically fueled tensions in the country, sparking anti-Kurdish rebel protests across the country and a firebomb attack on an office of the Kurdish party in Ankara overnight. -- SPA
