Shopping trolleys are placed to block the entrance of a Carrefour supermarket in Drogenbos, near Brussels, during a strike February 24, 2010. Carrefour, the world's No. 2 retailer, said it would cut jobs and close stores in Belgium to restore profitability in the country amid intense competition from local rivals. The plan calls for cutting 1,672 jobs and closing 21 stores in Belgium by end-June, Carrefour Belgium said in a statement on Tuesday. REUTERS/Yves Herman (BELGIUM - Tags: EMPLOYMENT BUSINESS)
