Cuba's Fidel Castro makes surprise appearance
Former Cuban President Fidel Castro has made an unannounced appearance at a Communist Party Congress alongside his brother, current President Raul Castro.
The two men received an emotional standing ovation from delegates in the Cuban capital, Havana.
It is the first time the two have appeared publicly together since Fidel, 84, handed over the presidency to Raul five years ago.
The BBC's Michael Voss in Havana said that Fidel Castro's appearance was a sign of support for his brother.
