Former Cuban President Fidel Castro, 88, appeared in public “full of vitality” for the first time in more than a year on Monday, greeting a delegation of Venezuelans, official media reported on Saturday (Sunday NZT).

It was his first known appearance outside his home since Cuba in December agreed to normalise relations with the United States, Castro’s longtime adversary.

Official media showed images of a seated Castro shaking hands with the visiting Venezuelans through the window of his vehicle, wearing a baseball cap and a windbreaker.

There was no explanation why five days passed before the encounter was reported in Cuba.

He met at a school with 33 Venezuelans, who were on a solidarity mission to Cuba, for about 90 minutes. Since the fall of the Soviet Union, oil-rich Venezuela has become Communist Cuba’s closest ally and chief benefactor.

Castro impressed the Venezuelans with a firm, long handshake and a lucid mind, the newspaper Juventud Rebelde reported in a writer’s first-person account.

Castro relayed “multiple details about life in Venezuela, especially now that this great nation has become the bull’s eye for imperial greed,” the report said, in apparent reference to US sanctions on Venezuela that declared the South American nation a national security threat.

“Fidel is full of vitality,” the report said.

Castro’s last previous public sighting came on January 8, 2014, at the opening of a Havana cultural center sponsored by one of his favorite Cuban artists, Alexis Leyva, alias Kcho.
