In Honduras, violence continues to spread over the disputed result of last November's presidential poll.
More than 30 people have been killed in protests across the Central American country.
Allegations of fraud sparked the unrest after the opposition candidate appeared set for victory.
On Saturday, security forces clashed with thousands of demonstrators who gathered near a stadium playing host to the president's swearing in ceremony.
"His duty was to hand over at the end of his administration, but instead what he did was steal our votes. He didn't steal (opposition candidate) Salvador Nasralla's votes; he stole them from the people," said one protester.
President Juan Orlando Hernandez called for unity after taking the oath of office again.
The Organization of American States said the election was marred by irregularities and has called for a new vote.
But the result was eventually ratified by the country's electoral tribunal and both Mexico and the United States have backed the incumbent.
