Venezuela's leader Hugo Chavez has called US President George W Bush as "the devil" in a speech at the United Nations General Assembly.
"The devil came here yesterday," he said, referring to Mr Bush's speech on Tuesday. "It still smells of sulphur today," he added.
US state department spokesman Tom Casey said that it was disappointing to see a head of state speak in such a way.
Mr Chavez went on to criticise the UN system which was "worthless".
The left-wing Venezuelan leader - allied to Cuba's Fidel Castro and with growing ties to fellow oil-producer Iran - has long had tense relations with the US.
UN 'worthless'
On Tuesday, Mr Bush had defended his policies on the Middle East and said democracy was gaining ground as terrorists were marginalised.
Mr Chavez, who brandished a copy of American leftist writer Noam Chomsky's Hegemony or Survival: America's Quest for Global Dominance, said Mr Bush promoted "a false democracy of the elite" and a "democracy of bombs".
"He came here talking as if he were the owner of the world," the Venezuelan leader said.
He called for drastic reform of the UN to reduce what he called US influence.
The UN in its current form "doesn't work", he said.
"I don't think anybody in this room could defend the system," the Venezuelan leader added.
"Let's be honest. The UN system born after World War II collapsed. It's worthless."
Mr Chavez's criticism of the UN echoed Iranian President Mahmoud Ahmadinejad's speech to the assembly late on Tuesday, BBC diplomatic correspondent Bridget Kendall reports from New York.
"As long as the UN Security Council is unable to act on behalf of the entire international community in a transparent, just and democratic manner, it will neither be legitimate nor effective," Mr Ahmadinejad said in a speech delivered a few hours after Mr Bush's appearance.
