A Greek presidential guard, known as an Evzone, take part in a changing of the guard ceremony at the Tomb of the Unknown Soldier, as riot police secure the Greek parliament during an anti-government rally of public transport workers, in central Athens, Wednesday, Dec. 8, 2010. Strikes have halted public transport in Athens for 24 hours, in the latest display of union opposition to austerity measures in crisis-hit Greece. Buses, the metro, trams and trolleys stopped in the capital Wednesday along with national rail services, as workers walked off the job in opposition to plans by the Socialist government to restructure state-run transport companies and reduce subsidy payments. less
