Authorities in western Bangladesh pleaded with football fans today to remove tens of thousands of Brazilian and Argentinian flags from their rooftops as World Cup fever grips the normally cricket-mad nation. Ahead of Thursday's big kick-off in Brazil, many Bangladeshi towns and cities have been turned into seas of either yellow and green or blue and white in a reflection of the huge support for the South American giants.Government administrator of Jessore district said the mass display of support for the tournament's two favourites was disrespectful to Bangladesh's own flag.
