Demonstrators gather during a rally for U.S. detainee Alan Gross in Lafayette Square in Washington December 3, 2013. The United States yesterday called for the immediate release of Gross, the American contractor jailed for the past four years in Cuba, saying his continued captivity on the communist-ruled island was "gravely disappointing."
