Venezuelan President Hugo Chavez arrived back home in Caracas early Friday after 10 days of medical treatment in Cuba, but his failure to show up at a regional meeting in Brazil raised new questions about his health.

State television showed images of Chavez arriving at Caracas' airport and walking down the steps of the presidential jet wearing a track suit. Chavez smiled and laughed heartily as he chatted with members of his Cabinet including Vice President Nicolas Maduro.
