Bahrain opposition leader ordered to face prosecutor after protest exhibition raid

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 in the Gulf nation.

It's unclear whether Ali Salman, the head of the Shiite bloc Al Wefaq, could face arrest on Sunday. Such a move could boost tensions sharply and open wider clashes between Shiite-led protesters and Bahrain's Western-backed 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 Saturday that Salman was ordered to the prosecutor's office, but gave no other details.

Bahrain is home to the U.S. Navy's 5th Fleet.
