#AP | Bahraini anti-government protesters chant slogans during a march in Sanabis, Bahrain, Monday, Feb. 11, 2013. Clashes erupted after the march between riot police firing tear gas and protesters hurling rocks. After nearly two years of nonstop unrest, opposing factions in Bahrain began talks on Sunday to ease an Arab Spring conflict that has run longer than Syria's rebellion and is playing out on the doorstep of the U.S. military's main naval base in the Persian Gulf. Signs read, "dignity strike, we are coming down to Martyrs Square on Feb. 14 and 15," referring to plans to attempt a return to the well-guarded site of the pro-democracy uprising that began Feb. 14, 2011.
