(CNN) -- [Updated 3 p.m. ET, Monday, October 24] The photo above was taken Thursday in Athens, Greece, where protesters clashed over the country's tough budget cuts.
The unpopular austerity measures are designed to bring down Greece's national debt. But they are also expected to cause about 30,000 job losses while cutting wages and pensions for workers in the public sector.
"We have no hope. The only hope we have is the strength of the people," said protester Vagelis Filezis, a civil engineer, before the vote. He said Europe's leaders were trying "to save the banks but they don't think about the people."
