World Reacts to Cuban Leader Fidel Castro's Death by Fern Robinson WASHINGTON -- Cubans in Havana took to the streets to mourn the passing of Fidel Castro. The passing of the man known to most Cubans as "El Comandante" -- the commander -- or simply "Fidel" leaves a void in the country he dominated for so long. "I am very upset. Whatever you want to say, he is public figure that the whole world respected and loved," said Havana student Sariel Valdespino. Meanwhile in Miami, Florida, about 145 kilometers (90 miles) away in the United States, Cubans took to the streets in celebration of Castro's death. Some were draped in Cuban flags, other danced in the streets, some dazed in disbelief that this day -- so long wished for -- was finally here. Watch: In Miami a celebration of Castro's death "Cuba si! Castro no!'' people chanted in the streets, while others screamed "Cuba libre!'' Forty-year-old financial executive Gabriel Morales, whose parents left Cuba decades ago, said the news of Castro's death "seems unreal.'' Carlos Lopez told the Miami Herald, "We are not celebrating one man's death, but the death of an ideology. We are celebrating that little piece of liberty we got back today." On Twitter, Gloria La Riva said, "...His legacy will endure because he leaves a strong country of true revolutionaries, people who have given of themselves countless times as medical workers, as teachers, as construction workers, as combatants, all for humanity..." Mexican President Enrique Pena Nieto said on Twitter, "I lament the death of Fidel Castro Ruz, leader of the Cuban revolution and emblematic reference of the 20th century." Former Soviet leader Mikhail Gorbachev hailed Castro for strengthening his island nation. "Fidel stood up and strengthened his country during the harshest American blockade when there was colossal pressure on him, and he still took his country out of this blockade to a path of independent development," Interfax news agency quoted Gorbachev as saying.
