Saudi Shiite men hold placards bearing portraits of prominent Shiite Muslim cleric Nimr al-Nimr during a protest on January 8, 2016 in the eastern coastal city of Qatif against his execution by Saudi authorities earlier in the week. Nimr was a driving force of the protests that broke out in 2011 in the kingdom's east, an oil-rich region where the Shiite minority of an estimated two million people complains of marginalisation.
