Cuban school children carry pictures of the five Cuban prisoners in U.S. jails, during celebrations for Cuban national hero Jose Marti's 160th birth anniversary in Havana January 28, 2013. The so-called "Cuban Five" are celebrated by many in Cuba as national heroes who were spying on armed exile groups in Miami to prevent attacks on their country and are victims of Washington's campaign against the communist-run island.
