A flag of Kurdish workers Party (PKK) hangs on a barricade as armed kurdish militants man a barricade, on November 18, 2015 in the Sur district of Diyarbakir. Tensions rose when pro-Kurdish MP Leyla Zana began her oath with 'Biji Asiti', or 'Long live peace' in Kurdish. The phrase triggered a storm that recalled her memorable swearing-in 24 years ago when she also spoke the language that was then still taboo in public.
