Summary:  
The documents detail a Cuban diplomatic protest letter submitted to Mexico on November 29, 1963, regarding the treatment of Sylvia Duran, a Cuban consulate employee in Mexico City.

The Cuban government accuses Mexican authorities of involvement in the U.S. plot against President Kennedy and asserts that the incident damages bilateral relations.
