At least 12 people have died and about 4,000 inmates released following a jail break at Haiti over the weekend.
This has forced the government to declared a 72-hour state of emergency and night curfew in and around the capital because of two jailbreaks and spiralling insecurity.
According to the BBC, armed gangs stormed a major Port-au-Prince prison.
Gang leaders say they want to force the resignation of Prime Minister Ariel Henry, who is outside the country.
The groups aiming to oust him control around 80% of Port-au-Prince.
A government statement said two prisons – one in the capital and the other in nearby Croix des Bouquets – were stormed over the weekend.
Among those detained in Port-au-Prince were gang members charged in connection with the 2021 killing of President Jovenel Moïse.
