CUBA - New photos of Fidel Castro have been posted on the Cuban state-run media website.
The photos purportedly show a smiling Fidel Castro greeting workers at a scientific think tank this week.
The 83-year-old former Cuban leader and head of Cuba's communist party is wearing a track suit and appears to be healthy.
The website credits the photos to Alex Castro.
No photographs of Castro have been taken publicly since he fell seriously ill in July 2006.
