PORT-AU-PRINCE, Jan 27 - Haitian police officers on Thursday blocked streets and forced their way into the country's main airport to protest the recent killing of officers by armed gangs expanding their grip on the Caribbean nation.

Protesters in civilian clothes who identified themselves as police first attacked Prime Minister Ariel Henry's official residence, according to a Reuter’s witness, and then flooded the airport as Henry was arriving from a trip to Argentina.

Henry was temporarily stuck in the airport, but returned to his residence in Port-au-Prince later on Thursday, followed by police protesters. A Reuters witness heard heavy gunfire near his home.

Haiti's National Police and the Prime Minister's Office did not immediately respond to requests for comment.

Roads around Port-au-Prince and in several cities to the north were blocked by protesters.

A group of U.S. government officials were visiting Haiti at the time, and a U.S. State Department spokesperson said all Washington's personnel were accounted for and they had moved some meetings as a precaution.

Haitian human rights group RNDDH said in a statement that 78 police officers had been killed since Henry came to power in July 2021, averaging five each month, saying the prime minister and the head of the national police Frantz Elbe were "responsible for each of the 78 lives lost during their reign."

"History will remember they did nothing to protect and preserve the lives of these agents who chose to serve their country," it added.

Last week, four police officers near the capital were killed by the Vitelhomme gang, while shootouts on Wednesday with the Savien gang in the town of Liancourt left another seven officers dead, according to Haiti's National Police and local media reports.

U.S. Assistant Secretary of State Brian Nichols expressed condolences to the families of police officers killed in the latest violence, and said the United States would continue to "impose costs on those responsible for this heinous violence."

Asked how the developments could affect efforts to craft an international armed intervention, the U.S. State Department spokesperson told Reuters the United States was still working with international partners to develop "a framework" for a security mission to "provide security and stability."

The United Nations is discussing sending a foreign strike force to confront the criminal groups. The proposal was originally made three months ago but no country has offered to lead such a force.
