Crowds Pack Havana Square For Pope Francis' Mass

Pope Francis led tens of thousands of Cubans in a mass in Havana's Revolution Square, the political heart of Cuba where the Communist government stages its biggest rallies. Following the mass attended by an estimated 300,000 people, the leader of the Catholic Church, Latin America's first pope, also met on Sunday with Cuban revolutionary leader Fidel Castro, discussing religion and world affairs at the home of the 89-year-old retired president.
