Violence has broken out in Port-au-Prince in recent days.
A large number of prisoners have been released after an armed group attacked the main prison in Haiti's capital, Port-au-Prince.
A local journalist told BBC News that the majority of the approximately 4,000 men held here are now at large.
Those detained included gang members charged in connection with the 2021 murder of President Juvenel Moïse.
Violence in Haiti, the poorest country in the Americas, has worsened in recent years. Gangs seeking to overthrow Prime Minister Ariel Henry control 80% of Port-au-Prince.
On Friday, Kenyan President William Ruto said he had signed an agreement with Henry and was working to speed up the deployment.

Since President Moise was assassinated in 2021, violence has been widespread. The president has not been replaced since 2016, and no elections have been held.
Under the agreement, elections were to be held and Mr Henry, who was not elected, was scheduled to step down by February 7, but this did not happen.
Since his departure for Kenya, unrest in Port-au-Prince has intensified, with gang leader Jimmy Chéridier (nicknamed “Barbeque”) declaring a coordinated attack to oust the prime minister.
“We are all united, both the armed groups in the provincial cities and the armed groups in the capital,” said a former police officer believed to be behind several massacres in Port-au-Prince.
Four police officers were killed and five others injured in a spate of shootings in the capital.
Over the weekend, the French embassy in Haiti advised against travel to and around the capital. Haiti's police union has called on the military to help strengthen prisons.
