Venezuelan President Hugo Chavez warned on Wednesday that a plot to assassinate him was being hatched in Guatemala, saying he might not attend the inauguration of the country's new president next month because of the alleged scheme. "I've received very recent information that worries us about Guatemala and puts at risk my attendance at the swearing-in of President (Alvaro) Colom," Chavez told a news conference in Venezuela's capital, Caracas. Chavez, an outspoken critic of US President George W. Bush, has alleged similar plots in the past and accused Washington of backing the plan. "The government of the United States, is always conspiring - not only to overthrow me (but), sometimes, even to kill me," Chavez said. "Hopefully there is a way to neutralize these plans." US officials have repeatedly dismissed Chavez's accusations of US-backed plots as ridiculous. A US Embassy spokeswoman in Caracas did not immediately return a message seeking comment.
