Chavez illness 'brought on by the enemy'

Venezuela's President Hugo Chavez is undergoing his "most difficult hours", his deputy has said.
Nicolas Maduro spoke at length in a speech apparently designed to reassure citizens despite the failing health of Venezuela's leader.
He accused the US of plotting against the Venezuelan government. Two US military attaches have been expelled.
Speaking in a room full of dignitaries including the defence minister and the president's brother, Adan Chavez, Mr Maduro said Mr Chavez's illness was an "attack" by his enemies and called for this to be investigated.
