Surging violence in Haiti from clashes with armed gangs since March has displaced nearly 580,000 people, according to a new report from the UN migration agency.

Haiti has long faced unrest, but at the end of February gangs unleashed co-ordinated attacks with gunmen taking control of police stations, opening fire on the main international airport – which remained closed for nearly three months – and storming Haiti’s two biggest prisons.

The report released on Tuesday by the International Organisation for Migration, said the displacement of more than half a million is mainly due to people fleeing the capital of Port-au-Prince for other provinces, which lack the resources to support them.

In March, the agency reported more than 362,000 internally displaced people in Haiti. The violence has more than doubled the number of internally displaced in the southern region — already ravaged by a 2021 earthquake — from 116,000 to 270,000.

“Nearly all those internally displaced are currently hosted by communities already struggling with overburdened social services and poor infrastructure, raising further concerns about tensions with the potential to spark further violence,” the report said.

With more than 2,500 people killed or injured across Haiti in the first three months of the year, Haiti’s National Police has been unable to bring the situation under control.

Marie Jean, 49, and her two children were displaced from their Port-au-Prince home after a gang killed her husband in February. She is now sheltered with her children at a public school.

“I lived in a comfortable home that my husband worked hard to build,” Ms Jean told The Associated Press.

“Now I’m living in a situation that’s inhuman.”

With the gangs in control of at least 80% of Port-au-Prince and critical roads leading to the rest of the country, many are living in makeshift shelters, including schools and learning institutions that are now hosting more than 60,000 people.

The gangs have been charging fees for those wanting to use the highways or blackmailing drivers to get their hijacked trucks back on the roads, where police presence is scarce.

Haiti’s acting prime minister Garry Conille, who was appointed last month, attended a ceremony on Tuesday where more than 400 officers graduated from the police academy, with the expectation that they will help curb gang violence in Haiti.

He reminded the graduates that the people count on their dedication to combat insecurity.

“You need to know that you are not alone,” Mr Conille said. “You are the hope of the population at this crucial moment in our history.”

Violence is also on the rise outside Haiti’s capital. Last week, armed gangs attacked families located in Terre-Neuve, a village in northern Haiti, forcing more than 1,000 people to flee their homes.
