Venezuela's vice-president has accused a right-wing group in the US of being behind rumours about President Hugo Chavez's health as he continues battling for his life.
Speaking after a mass at a military hospital in honour of the president, Nicolas Maduro said:
"They're part of a wing of the imperial power of the United States that's the wing that has made more disasters and wars in our continent".
Mr Maduro also said Mr Chavez is receiving chemotherapy and radiation treatment.
Last week, after more than two months of in a Cuban hospital, Chavez returned to Caracas where he is being treated at a military hospital.
