Thousands of people have taken to the streets of the Haitian capital Port-au-Prince and other cities for renewed protests against the government.
They lit barricades of burning tyres and debris, demanding the resignation of President Jovenel Moïse.
Some demonstrators were reportedly injured as police fired rubber bullets to disperse them.
The cause of the Caribbean nation’s fresh unrest is a bitter dispute over Mr Moïse’s legitimacy.
Haiti’s opposition says that Mr Moïse’s five-year term should have ended on 7 February 2021, five years to the day since his predecessor in office, Michel Martelly, stepped down.
Mr Moïse, however, insists he has one more year to serve as he did not take office until 7 February 2017.
The year-long delay was caused by allegations of electoral fraud which eventually saw the result of the 2015 election being annulled and fresh polls being held, which were won by Mr Moïse.
