SYDNEY (AFP) - Two police were injured and up to 20 people arrested in clashes between authorities and anti-capitalism protesters in Australia's second-largest city Melbourne on Friday. Police used pepper spray to subdue some protesters as they attempted to turn scores out of City Square where they have been camped out for almost a week as part of the global anti-corporate greed "Occupy" protests. "I've been throwing water on my eyes, I've been rubbing onion in my eyes, I've even thrown milk on eyes to cool the sting, but my face is still on fire so I'm going to go off to the ambulance now," one demonstrator told the ABC.
