President Obama and Cuban President Raúl Castro met Monday as part of Obama's historic visit to the Cuban capital marking the revitalized relations between the two countries.<br />It was their third face-to-face encounter since the two countries began to normalize relations 15 months ago, but it was the first on Castro's home turf and the first visit of a U.S. president to the island in 88 years.<br />Obama and Castro are scheduled to have two back-to-back meetings, the most extensive high-level talks between the United States and Cuba in decades.
