Venezuelan President Hugo Chavez has said he believes the US government is planning to assassinate him. "If they kill me, the name of the person responsible is [President] George Bush," Mr Chavez said. Mr Chavez - who offered no evidence to back his claim - said any attempt on his life would backfire and threatened to cut off oil supplies to America. He was apparently reacting to growing criticism by top US officials of his left-wing government. US Secretary of State Condoleezza Rice has recently described the former paratrooper as a "negative force" in Latin America, while CIA chief Porter Goss said Venezuela was a possible source of instability in the region. Washington blames Mr Chavez of being heavy-handed towards Venezuela's opposition, and has recently criticised Caracas for arms purchases from Russia. Diplomatic ties between Washington and Caracas have soured since Mr Chavez came to power in 1999.
