Supporters of Venezuela's Hugo Chavez began setting off fireworks and partying in the street on Sunday night in anticipation of victory in the presidential election.
Various aides to Chavez published celebratory messages on Twitter, while some supporters of opposition leader Henrique Capriles began crying at his campaign center, Reuters witnesses said.
Interior Minister Tareck el Aissami tweeted: "Perfect victory! The fatherland has won".
