Haiti says it will investigate Monday's riots that prompted the president of the Dominican Republic to cut short his visit to the Haitian capital of Port-au-Prince.
The Haitian government issued a statement Tuesday ordering an investigation into the violence and vowing to punish those responsible.
At least two people were injured Monday when police confronted protesters gathered outside Haiti's presidential palace, where Haiti's interim president Boniface Alexandre was meeting with Dominican president Leonel Fernandez. Officers fired automatic weapons into the air as demonstrators burned tires and threw stones in protest of a new Dominican practice of expelling Haitians working illegally inside its borders.
The Dominican president left Haiti following the riots.
About a million Haitians live in neighboring Dominican Republic, where they work at low-paying jobs to escape Haiti's destitution. Many are in the Dominican Republic illegally.
