The US had been trying to "strangle the Cuban economy" with measures to cause medicine shortages and block purchases and donations of medical equipment to treat COVID-19, the Rock Around The Blockade solidarity campaign said.
The Trump administration's Title III measures, added to the Helms-Burton Act in April last year, have led to the increased shortages, the campaign wing of the Revolutionary Communist Group said.
According to the group, Washington claims that Cuban medical internationalists were "slaves" despite nearly 4,000 specialists from the island nation treating COVID-19 infections in nearly 40 countries.
