CARACAS (AP) -- Venezuelan President Hugo Chavez said that Cuba's Fidel Castro has visibly improved, describing how the Cuban leader has gained weight and is walking around and studying.

"A notable improvement," Chavez said, describing Castro's condition when the two met recently in Havana.

"He has gained several kilograms, and I think he is walking about more than me, analyzing, studying," Chavez said at a news conference in Caracas.

Footage of the meeting aired by Cuban state television on Tuesday evening were the first video images of the 80-year-old Cuban leader released in three months.

Chavez held up a copy of the Cuban Communist Party daily Granma with pictures from the meeting and pointed at a photo. "They said Fidel was dying," he said with a laugh. "He was having a ball."

Cuban authorities have insisted that Castro is recovering, and have denied reports by U.S. intelligence officials that he had terminal cancer.

During the half-year since Castro announced he had undergone intestinal surgery, the nation has been governed by his brother Raul and a team of top leaders that includes Vice President and Cabinet Secretary Carlos Lage.
