A protester confronts riot police outside parliament during a rally in central Athens, Thursday, July 8, 2010. The Greek government is battling growing discontent over a new round of economic austerity, with fresh strikes, public hostility, and party dissent testing the nation's ability to make it out of its debt crisis. Unions on Thursday staged their sixth general strike this year _ halting public transport and services, stopping ferry departures and closing schools, newspapers, courts and public hospitals.
