Venezuelan President, Hugo Chavez, is suffering from "complications" brought on by a "severe lung infection" which developed after surgery, officials say. Hugo Chavez 58, had his fourth operation for cancer in Cuba on 11 December and then developed a respiratory infection. Venezuelan Information Minister Ernesto Villegas said in a statement carried by the BBC, the infection had "led to a respiratory insufficiency". Chavez has faced complications as a consequence of a severe lung infection," he added. Ernesto Villegas also warned Venezuelans not to be taken in by a "psychological war" being fought in the media which had the "ultimate aim of destabilizing the Bolivarian republic". Chavez is due to be sworn in for another term in office on 10 January. He has been in power since 1999 and was elected for a fourth term in office in October
