A senior official in Bahrain's main opposition group says it plans to file a complaint with the United Nations over a police raid on an exhibition chronicling the Arab Spring-inspired uprising in the Gulf nation.

Authorities on Thursday claimed the museum-style hall contained displays promoting "hatred."

But opposition group Al Wefaq said the storming Wednesday was unjustified because the topics are mentioned in a government-backed report in 2011 on the struggles between Bahrain's Shiite majority and its Sunni rulers. The exhibition included depictions of protesters killed in clashes and interrogation rooms used for alleged torture.

Al Wefaq official Hadi al-Musawi told reporters the group plans to file a grievance with the U.N.'s special rapporteur on freedom of expression.

More than 65 people have died in Bahrain's unrest since February 2011.
