Bahrain opposition leader faces prosecutor BAHRAIN'S main opposition group says its leader has been called to the state prosecutor's office over an exhibition that showed alleged abuses against anti-government protesters. It's unclear whether Ali Salman, the head of the Shi'ite bloc al-Wefaq, could face arrest on Sunday. Such a move could boost tensions sharply and open wider clashes between Shi'ite-led protesters and Bahrain's Sunni rulers. Riot police last week raided the museum-style hall opened by al-Wefaq that included depictions of alleged torture and heavy-handed tactics against protesters during 32 months of unrest. Authorities said the displays incited "hatred." Al-Wefaq said on Saturday that Salman was ordered to the prosecutor's office, but gave no other details.
