By Andrew Cawthorne CARACAS (Reuters) – President Nicolas Maduro’s government plans to nominate a new ambassador to the United States on Tuesday despite accusing Washington of fomenting violence which has killed more than 13 people, Venezuela’s worst unrest in a decade. Disputes between the ideologically opposed governments were common during the 1999-2013 rule of late socialist leader Hugo Chavez and have continued under his successor, although the United States remains the OPEC member’s main export market. “U.S. society needs to know the truth about Venezuela,” Maduro said at a meeting with state governors late on Monday in the latest of his daily speeches to the nation. They’re asking for U.S. military intervention in Venezuela.
