Venezuelan President Hugo Chavez is suffering from a new, severe respiratory infection following cancer surgery, the government information minister has said.

Mr Chavez, 58, returned to Venezuela last month after being treated for cancer in Cuba, but has not appeared in public since.

Information Minister Ernesto Villegas said Mr Chavez's condition continued to be very delicate.
