Venezuelan Opposition Leader Juan Guaido says he has started the “final phase” of his plan to oust the Venezuelan President Nicolas Maduro.
He is calling on Venezuelans and the military to back him.
Guaido, in a video posted on his Twitter account, was accompanied by men in military uniform and opposition politician Leopoldo Lopez, who has been placed under house arrest.
Videos emerged on social media showing military personnel calling on Venezuelans to join Guaido and “join freedom.”
Images posted to Twitter show Venezuelans gathering to protest.
Nelson Chamisa, Zimbabwe's opposition leader, says President Emmerson Mnangagwa's election victory is a "coup against [the people's] will".
Chamisa believes that the results announced late on Thursday evening were fake, and said he had won Monday's presidential poll.
However, the electoral commission said no dishonest behaviour was involved in the vote tally.
This was the first election since long-term leader Robert Mugabe was ousted.
Addressing journalists on Friday afternoon, the opposition leader called on his rival not to accept "corrupted results".
