Policemen stand behind barricades as a protester uses a baton outside the venue for the G20 summit in Melbourne November 18, 2006. A protest against the summit turned violent when 2,000 chanting protesters marched through the city towards the venue, with a police van destroyed, barricade lines broken, glass bottles, flares, steel rods and upturned barricades being thrown at police in riot gear. The meetings with finance ministers and central bankers from the world's biggest economies, including China, India, the United States, Japan and Britain, will discuss ways to ensure energy and resource security.
