Hundreds of protesters gathered last Friday to criticise a recent court decision in the Dominican Republic that could strip the citizenship of generations of people of Haitian descent living in the neighbouring country.
The crowd peaked at about 2,000 people but thinned out during the march uphill to the Dominican Embassy to protest the decision passed two months ago by that country's court. The demonstrators urged people to boycott travel to the Dominican Republic.
The ruling has been met with sharp objection from Caribbean leaders to the United Nations.
On Friday, the Inter-American Commission on Human Rights became the latest international entity to oppose the court decision, calling on the Dominican government to take urgent measures to guarantee the rights of those people affected.
Advocacy groups estimate 200,000 people, many of them of Haitian descent, could lose their Dominican citizenship because of the court ruling. Dominican officials say only about 24,000 would be affected.
Haitian officials have said little about the matter. President Michel Martelly has called it a "Dominican issue" and Prime Minister Laurent Lamothe posted on Facebook that a lot "is being done to solve the problem".
The lack of a robust response from the Haitian government was cited as one reason for the protest. Demonstrators carried a coffin spray-painted with the slogan 'Down with Martelly'.
Friday's march is the latest of recent protests in Haiti, many of them critical of Martelly's government. A few have turned violent, with anti-government demonstrators last week burning tyres outside the US Embassy as they pressed for the departure of Martelly, accusing the US of interfering in Haiti's domestic politics.
Haiti and the Dominican Republic have long had a volatile relationship as neighbours on the Caribbean island of Hispaniola. But the Dominican Republic put aside such differences and was among the first responders after Haiti's devastating 2010 earthquake.
