Cuban national flags wave in front of the U.S. Interest Section in Havana, Cuba, 13 August 2008. In 2006 the US installed the giant electronic banner on the fifth floor of their building in the centre of Havana and start to broadcast political propaganda, news, messages and statements. In return, the Cuban government erected so called "Monte de las Banderas" (Forest of Flags), 138 flagpoles in front of the building to prevent Cubans from seeing the scrolling letters.
