In Bahrain, the government has bulldozed dozens of mosques in Shi'ite villages in recent days as part of a crackdown on Shi'ite-led protests. In the ancient village of Aali, where some graves date to 2000 BCE, the 400-year-old Amir Mohammed Braighi mosque was demolished. At least 28 Shi'ite mosques have been demolished over the past two months since the protests began, under the pretext that they are not "licensed." (AlJazeera, May 13; McClatchy Newspapers, May 8)
