A Bahraini protester holds a placard portraying Sheikh Ali Salman, head of the Shiite opposition movement Al-Wefaq, on March 24, 2015, during a demonstration against his arrest, in the village of Daih, west of Manama. Salman is behind bars for allegedly trying to overthrow the regime. His arrest on December 28, 2014, shortly after he was re-elected head of Bahrain's main opposition party Al-Wefaq, has sparked near-daily protests in Shiite villages.
