Fidel Castro was seen in the image wearing a blue and white track suit and surrounded by workers of the National Center for Scientific Research. Castro appears to be healthy and jolly in almost all of the shots.
"Today we had the honor of Fidel paying a surprise visit to the center... He is thin but looks well and our boss said mentally he was doing very well," an unnamed blogger reported, saying the images were shot with a cell phone.
In 2008 Fidel Castro secede his powers as Cuba's head of State to his brother Raul Castro. However, Fidel Castro still heads the Cuba Communist Party and continues to write political columns for state media.
