Some thousands of supporters demonstrate waving various PKK flags and posters of jailed Kurdish rebel leader Abdullah Ocalan, in southeastern Turkish city of Diyarbakir, Turkey, Thursday, March 21, 2013, as Ocalan called Thursday for an immediate cease-fire and for thousands of his fighters to withdraw from Turkish territory, a major step toward ending the fighting for self-rule for Kurds in southeastern Turkey, one of the world's bloodiest insurgencies lasting nearly 30-years and costing tens of thousands of lives.
