At the start of his historic three-day visit to the island of Cuba, President Barack Obama said that “change would happen” in Cuba and that Cuban President Raul Castro (who he will meet later on Monday) understood that, reports the BBC. However, hours before Obama landed in Cuba on Sunday, Cuban authorities arrested more than 50 dissidents marching to demand improved human rights, according to USA Today.
