Cuba is ramping up preparations for a US invasion.
Cuban President Miguel Diaz-Canel said the country is ready to repel any foreign military aggression.
Cuba is preparing to implement the "whole people's war" doctrine, which includes not only the regular army but also reservists, territorial defense units and civilians under the protection of the state.
Diaz-Canel demanded that the US end its economic blockade of the island and stop putting pressure on Havana.
