Hundreds of protesters faced off with left-wing opponents yesterday in a standoff over plans to build a mosque in a rural Australian town, the latest anti-Islam protest since a Muslim teenager killed a police officer this month. Right-wing activists from the United Patriots Front, which says that its aim is opposing the spread of Islam, faced off with members of a left-wing coalition promoting tolerance in the town of Bendigo in Victoria state. The dispute began over plans to build a mosque in the town and has been simmering for months. Police said four arrests were made, but all were subsequently released.
