US President Barack Obama leaves Cuba after historic trip

President Barack Obama has left Havana after a historic three-day visit, the first to Cuba by a US leader in nearly nine decades.
Obama, who was heading to Argentina, was seen off at the airport by Cuban President Raul Castro yesterday.
Earlier, Obama said that his visit meant the two countries could "bury" their Cold War-era hostility and he also called for Cuba to allow more political and media freedom.
