Riot police use shields to move supporters of detained protesters from outside the Labor Ministry in Athens, 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. (Thanassis Stavrakis/AP Photo)
