And in Cuba, 138 huge black flags have been placed in front of the U.S. diplomatic mission in Havana. The Cuban government said the flags pay honor to what they describe as Cuban victims of U.S.-backed terrorism. The flags will also block the U.S. government from operating an electronic news ticker from its window. On Monday protesters also held up 138 photographs of the 73 victims of a 1976 plane explosion. Cuba has been calling on the U.S. to extradite the alleged mastermind of the attack, Luis Posada Carriles, to stand trial in Venezuela.
