President Barack Obama has arrived in Cuba for a historic visit to the island and talks with its communist leader.
He is the first sitting US president to visit since the 1959 revolution, which heralded decades of hostility.
Speaking at the reopened US embassy in Havana, he called the visit "historic". He also spent time in the old city.
Mr Obama will meet President Raul Castro, but not retired revolutionary leader Fidel Castro, and the pair will discuss trade and political reform.
The US president emerged smiling from Air Force One with First Lady Michelle and their daughters Sasha and Malia.
