Yoani Sanchez reports in Spanish via Twitter that yesterday around 1:00 pm opposition activists deployed "Zapata Vive" signs, and shouted "Libertad" ["Freedom!"] on the steps of the [former] National Capitol [El Capitolio].  The building, which used to house the Cuban Congress during the republican era, is a tourist attraction, and Yoani reports that several tourists joined the protesters shouting "¡Libertad!".  It was a very brief act, but the news of it are still circulating around Havana.
