Barack Obama has become the first US President in 88 years to visit Cuba after Air Force One touched down in Havana.
As the plane landed at a rainy Jose Marti International Airport, Mr Obama tweeted: “What’s up Cuba? Just touched down here, looking forward to meeting and hearing directly from the Cuban people.”
The President was greeted by foreign minister Bruno Rodriguez – not president Raul Castro.
Instead he will hold talks with his Cuban counterpart later today.
The two announced they would re-open diplomatic relations in December 2014, ending an estrangement that began when the Cuban revolution ousted a pro-American government in 1959.
Commercial flights have been resumed and respective embassies reopened, but the economic embargo of Cuba remains after Republicans in the US blocked its rescission.
Mr Obama travelled with daughters Malia and Sasha, the first lady and her mother.
After their arrival, the President called his visit an “historic opportunity to engage with the Cuban people”.
