Venezuela’s Nicolas Maduro has been sworn in for a third presidential term despite the protests of the country’s opposition movement, capping more than five months of dispute over last summer’s contested election.

President Nicolás Maduro will extend his increasingly repressive rule over Venezuela until 2031 when he is sworn in on Friday, despite credible evidence that his opponent won the latest election and following protests against his plan to serve a third six-year term.

The United States on Friday imposed sanctions on eight Venezuelan officials and increased to $25 million the reward it is offering for the arrest of President Nicolas Maduro on the day of his inauguration to a third term following a disputed election last year.
