Bahrain has always been divided between the Sunni ruling élite, centred on the Khalifa royal family, and the Shia, but since March this has turned into something closer to an anti-Shia pogrom. Evidence of official sectarianism is widespread. After watching the beginning of a riot in Nuwaidrat we drove to a quieter part of the village where 10 Shia mosques had been destroyed three months earlier. A local man, who is writing a history of Shia mosques and holy sites in the neighbourhood and does not want his name published, points to a heap of rubble saying "this used to be the Momin mosque where 200 to 300 people worshipped. There has been a mosque here for 400 years".
