Cuba has begun nine days of mourning following the death of revolutionary leader and former President Fidel Castro, who died Friday at the age of 90. In Havana, tens of thousands of people lined up to pay their respects to Castro, who launched the Cuban revolution to oust the U.S.-backed Cuban dictator, Fulgencio Batista, and went on to lead Cuba for nearly a half-century. This is one of the mourners, professor Maydelis Savon.

Maydelis Savon: “Before anything else, I am a revolutionary. I am compelled to be here because I am part of the people. Also, Fidel Castro fought so that all Cubans can have the same rights.”

Bolivia has declared a week of mourning for Castro, whose revolution inspired revolutionary efforts across Latin America and the globe and led Castro to become one of the archenemies of the United States. On Monday, President-elect Donald Trump threatened to undo President Obama’s re-establishment of formal diplomatic relations with Cuba and reimpose the crushing economic sanctions against Cuba. Trump tweeted, “If Cuba is unwilling to make a better deal for the Cuban people, the Cuban/American people and the U.S. as a whole, I will terminate deal.”
