Venezuelan President Nicolas Maduro, whose nearly 12 years in office have been marked by a deep economic and social crisis, is set to be sworn in for a third term on Friday, staying in power despite a six-month-long dispute over a July election and international calls for him to stand aside.

President-elect Donald Trump gave Venezuelan President Nicolas Maduro a stern warning on Thursday not to harm his country’s opposition leader.

Venezuela opposition leader María Corina Machado's aides said she was detained Thursday, followed moments later by official denials of her arrest, in a confusing episode that capped a day of protests seeking to block President Nicolás Maduro from clinging to power.
