The United States has officially re-opened its embassy in Havana, 54 years after last closing its doors.
At a ceremony in the Cuban capital, the US Secretary of State John Kerry said: "The time has come for us to move in a more promising direction".
"The road of mutual isolation, estrangement that the US and Cuba have been traveling is not the right one."
"The establishment of normal diplomatic relations is something two countries do together when the citizens of both will benefit."
He added that the re-opening of the embassy was important on both a "people-to-people and government-to-government" level.

He also said the US government would strongly favour Congressional action to lift an overall US embargo on trade with Cuba.
The United States formally dropped Cuba from its list of state sponsors of terrorism back in May.
And there are also plans for an expansion of travel, and expanded sales and exports of certain goods and services from the US to Cuba.

While Mr Tracy said: "I'm gonna love seeing that flag go back up".
