An "End the blockade of Cuba" sign is held up outside the Cuban embassy after a flag-raising ceremony in Washington, D.C., U.S., on Monday, July 20, 2015. A diplomatic freeze that stretched five decades, outlasting the Cold War and nine U.S. presidencies, formally ends Monday when Cuba and the U.S. reopen embassies.
