Chávez's followers commemorate 21st anniversary of failed coup
Vice-President Nicolás Maduro promised a civilian-military surprise
The celebration will begin after a special ceremony at the Military History Museum, at 23 de Enero neighborhood.
Chávez's followers are to participate in rallies in different places in west and downtown Caracas.
The celebration includes a "civilian-military surprise," said Executive Vice-President Nicolás Maduro on Saturday.
Ever since last March 9, when US President Barack Obama issued an Executive Order declaring Venezuela an "unusual and extraordinary threat" to the United States, the Venezuelan government has screamed denunciations of supposed plans of invasion or military incursion by the United States.
