Protesters stand in front of the parliament building during violent protests against austerity measures in Athens' Syntagma (Constitution) square, June 28, 2011. With Greece teetering on the brink of bankruptcy, parliament is due to vote this week on a package of spending cuts, tax increases and privatisations agreed as part of a massive bailout aimed at averting the euro zone's first default.
