Cuba organized its major annual commemoration July 26 event in Santiago de Cuba.
This underscores 73 years in the wake of the 1953 Moncada Barracks attack.
Raúl Castro was missing.
President Miguel Díaz-Canel addressed the U.S. government at the event.
He claimed Washington tried to wipe out Cuba and take its land.
Residents in Havana got ready for the ceremonies.
They did this despite this with acute water problems, caused by ongoing power shortages.
