A 21-gun salute echoed across the Havana, as thousands of Cubans started gathering in Revolution Square to bid farewell to Fidel Castro. <br /><br /> People began queuing up as early as 4 a.m. to be at the head of one of three lines of mourners entering a square that has been central to Cuba’s recent history and where the revolutionary leader gave many of his speeches.<br /><br /> El Comandante’s death marks the end of an era and has added to worries among Cubans that Donald Trump will undo two years of dialogue between the two countries. The U.S. President-Elect has struck a very different tone from Barack Obama, who reached an agreement in 2014 with Castro’s younger brother President Raul Castro to end half a century of hostilities.<br /><br /> The ceremony in the capital will end on Tuesday night when foreign leaders are expected to pay their respects.<br /><br /> Fidel Castro addresses a crowd during an event at Revolution Square in Havana Cuba. pic.twitter.com/LGTumIvjAH— allan crawshaw (@allan_crawshaw) November 26, 2016<br />
