More than 500 uniformed police officers have joined a "march of anger" in Port-au-Prince to protest for better salaries for law enforcement.
"Our wages are miserable. We don't have insurance: we have an insurance card but at every hospital we go to, we have to pay,"they said.
With their faces hidden, several plainclothes police fired in the air near the anti-government protesters.
Prior to the protests, police officers had complained at the headquarters of the Haitian National Police (PNH).
Separately, a man was beaten to death and then burned by some demonstrators who claimed that he opened fire on a crowd of marchers demanding that President Jovenel Moise step down.
