Maitham al-Salman, the man in charge of religious freedoms in Bahrain’s Human Rights Watch, said Sunday that unknown assailants attacked the mosque and looted some equipment there, after causing damage to the worshipping site.
Activists have repeatedly blamed the Bahraini regime for such attacks.
Since mid-February 2011, when anti-government protests erupted in Bahrain, Saudi-backed regime forces demolished over two dozen mosques in their crackdown on Bahrainis.
According to local sources, scores of people have been killed and thousands arrested so far during the regime clampdown on peaceful demonstrations.
Manama forces have also destroyed 18 mourning halls since the start of the revolution.
