Riot police use shields to move away supporters of detained protesters from outside the Labor Ministry in Athens, Wednesday, Jan. 30, 2013. Protesters from a Communist-backed labor union forced their way into a government building and clashed with police who used tear gas to expel them. Members of the union are protesting planned reforms to the country's pension and income contribution system — part of ongoing austerity cuts demanded by Greece's euro partners and the International Monetary Fund who are keeping the country afloat with emergency loans.
