CARACAS, Venezuela (AP) — President Hugo Chavez's new complications after cancer surgery prompted his closest allies to call for Venezuelans to pray for him on Monday, presenting an increasingly bleak outlook and prompting growing speculation about whether the ailing leader has much longer to live.

Vice President Nicolas Maduro looked weary and spoke with a solemn expression as he announced in a televised address from Havana on Sunday that Chavez now confronts "new complications" due to a respiratory infection nearly three weeks after his operation. He described Chavez's condition as delicate.

The streets of Caracas were abuzz on Monday with talk of Chavez's increasingly tough fight, while the news topped the front pages of the country's newspapers.
