Cubans Mourn Castro, As Week of Mourning Begins by VOA News Cubans are mourning Fidel Castro, the country's revolutionary leader whose death was announced Saturday. Flags are flying at half-mast across the country, as Cuba enters a week filled with memorials to mark his passing. The socialist revolutionary, who had long been ill, died late Friday at the age of 90. A cause of death has not been announced. A series of memorials begins Monday, when Cubans gather in Havana's iconic Revolution Square, where Castro often addressed adoring crowds. Students place candles around an image of the late Cuban leader Fidel Castro, at the university where Castro studied law as a young man, during a vigil in Havana, Cuba, Nov. 26, 2016. Castro's remains will then go on a four-day tour across the island nation, before being buried December 4 in Santiago. The socialist leader grew up near Santiago, and launched his first failed attempt at revolution in 1953 from the eastern city. Castro would go on to mount a successful revolt against the U.S.-backed government of Fulgencio Bautista starting in 1959. He eventually set up a one-party socialist government, which constantly defied Washington and allied itself with the former Soviet Union. Castro handed power to his brother, Raul Castro, in 2006, although he still exercised some power behind the scenes until recent years.

A polarizing figure throughout his life, Castro also prompted a mixed reaction in his death. In Cuba, many mourned the loss of a man who dominated the country's politics for over 50 years and helped foster a sense of independence and patriotism. US reactions In nearby Miami, however, large crowds of Cuban Americans danced in the streets, celebrating the passing of a man they saw as a dictator. People celebrate after the announcement of the death of Cuban revolutionary leader Fidel Castro in the Little Havana district of Miami, Fla., Nov. 26, 2016. World leaders were also divided in their response to Castro's death. U.S. President Barack Obama released a statement that was largely neutral in its reference to Castro, saying the U.S. extends its "hand of friendship" to the Cuban people. Meanwhile, President-elect Donald Trump's statement slammed Castro as a "brutal dictator who suppressed his own people for six decades." Starting in 2014, Obama oversaw a historic warming of relations between the U.S. and Cuba, including the restoration of diplomatic ties.

Trump's incoming chief of staff, Reince Priebus on Sunday said Trump was "absolutely" willing to reverse Obama's opening to Cuba. Talking to Fox News Sunday, Priebus said the future of U.S.-Cuba relations depends on whether Havana makes progress on human rights. "Repression, open markets, freedom of religion, political prisoners -- these things need to change in order to have an open and free relationship," Priebus said.
