A woman weeps hugging a book with the image of Venezuela's late President Hugo Chavez and Fidel Castro, as she leave a tribute for the South American leader at Revolution Plaza in Havana, Cuba, Thursday, March 7, 2013. The Cuban government declared two days of national mourning and ordered flags to fly at half-staff after the death of Chavez. Some islanders worried about the loss of the country's No. 1 ally, who has sent billions of dollars of oil to Cuba at preferential terms. (AP Photo/Ramon Espinosa)
