Russia on Wednesday rejected a U.S. allegation it had persuaded Venezuelan President Nicolas Maduro not to flee the country the previous day, calling the assertion a calculated attempt to demoralize the army and escalate the crisis there.

U.S. Secretary of State Mike Pompeo told broadcaster CNN on Tuesday that Maduro was prepared to leave the country that morning in the face of a call for an uprising by opposition leader Juan Guaido, but reversed his plan after Russia intervened.

Pompeo suggested Maduro had been planning to fly to Cuba, which Maduro himself has since dismissed.
