Haitis government declared a 72-hour state of emergency on Sunday after armed gangs stormed a major prison. At least 12 people were killed and about 3,700 inmates escaped in the jailbreak.

Gang leaders are demanding the resignation of Prime Minister Ariel Henry, whose whereabouts are unknown since he travelled to Kenya.

Gangs control around 80% of the capital, Port-au-Prince.

Gang violence has plagued Haiti for years.

A government statement said two prisons “ one in Port-au-Prince and the other in nearby Croix des Bouquets “ were stormed over the weekend.

It said the acts of disobedience were a threat to national security and said it was instituting an immediate night-time curfew in response, which started at 20:00 local time (01:00 GMT on Monday).

Haitian media reported that police stations were attacked, distracting authorities before the coordinated assault on the jails.

Among those detained in Port-au-Prince were suspects charged in connection with the 2021 killing of President Jovenel Moïse.

In the capital, gangs have erected barricades to prevent security forces from encroaching on their territory, while their strongholds in Port-au-Princes vast shantytowns are still largely on lockdown.

Schools and many businesses are closed, and there are reports of looting in some neighbourhoods.

Police have set up roadblocks and there is much uncertainty on the streets.

The latest upsurge in violence began on Thursday, when the prime minister travelled to Nairobi to discuss sending a Kenya-led multinational security force to Haiti.

Gang leader Jimmy Chérizier (nicknamed Barbecue) declared a co-ordinated attack to remove him.

All of us, the armed groups in the provincial towns and the armed groups in the capital, are united, said the former police officer, who is accused of being behind several massacres in Port-au-Prince.

Haitis police union had asked the military to help reinforce the capitals main prison, but the compound was stormed late on Saturday.

On Sunday the doors of the prison were still open and there were no signs of officers, Reuters news agency reported. Three inmates who tried to flee lay dead in the courtyard, the report said.

A journalist for the AFP news agency who visited the prison saw around 10 bodies, some with signs of injuries caused by bullets.

One volunteer prison worker told the Reuters news agency that 99 prisoners “ including former Colombian soldiers jailed over President Moïses murder “ had chosen to remain in their cells for fear of being killed in crossfire.

They have now been transferred to a different prison.

The US embassy in Port-au-Prince on Sunday urged its citizens to leave Haiti as soon as possible. The French embassy said it was closing visa services as a precaution.

While Haiti has been plagued by gangs for years, the violence has further escalated since President Moïses assassination at his home in 2021. He has not been replaced and presidential elections have not been held since 2016.

Under a political deal, Mr Henry was due to stand down by 7 February. But planned elections were not held and he remains in post.

A spokesperson for the White Houses National Security Council said it was monitoring the rapidly deteriorating security situation with grave concern.

They said the path forward lies with free and fair elections and violence serves only to delay a democratic transition while¦ upending the lives of thousands.

Speaking to the BBCs Newsday, Claude Joseph “ who was serving as acting prime minister when President Moïse was assassinated and who is now head of the opposition party called Those Committed to Development “ said Haiti was living through a nightmare.

Mr Joseph said Prime Minister Henry wanted to stay as long as possible in charge.

He agreed to step down on 7 February. Now he decides to stay, despite the fact that there are huge protests throughout the country asking him to step down “ but its unfortunate that now those criminals are using violent means to force him to step down.

In January, the UN said more than 8,400 people were victims of Haitis gang violence last year, including killings, injuries and kidnappings “ more than double the numbers seen in 2022.

Many health facilities have stopped operating because of the bloodshed.

Anger at the shocking levels of violence, on top of the political vacuum, have led to several demonstrations against the government, with protesters demanding the resignation of the prime minister. (BBC)
