Two Haitian reporters were fatally shot and their bodies set on fire while reporting in a slum controlled by gangs in the capital.
Haiti's Association of Independent Journalists says this is the second such incident this year.
The association says the two men were among seven journalists who came under attack Sunday in Cite Soleil, Port-au-Prince while investigating worsening violence in the area, including the recent killing of a 17-year-old girl.
The victims have been identified as Tayson Latigue and Frantzsen Charles.
The journalists were reportedly ambushed by two warring gangs. Their bodies have not been recovered.
Five other reporters fled, unharmed.
The Association of Independent Journalists has condemned what it called a "villainous and odious act" and demanded that the government improve the country's worsening insecurity amid a spike in killings and kidnappings.
Prime Minister Ariel Henry has also condemned the killing of the reporters.
