[8][2][9] In early March 2024, the Revolutionary Forces of the G9 Family and Allies staged the largest jailbreak in Haitian history and escalated attacks across the country, including an attempted siege of the Toussaint Louverture International Airport.

Chérizier claimed responsibility for the attacks and stated that the goal was to capture key government institutions, overthrow the unelected acting prime minister Ariel Henry and become more powerful in Haiti,[10] warning that "if Ariel Henry doesn't step down and the international community continues to support him, they will lead us directly to a civil war which will end in genocide.

[2] Chérizier is the leader of the Revolutionary Forces of the G9 Family and Allies (G9, Haitian Creole: Fòs Revolisyonè G9 an Fanmi e Alye), a self-described federation of rebel groups.

[19] As of July 2021, it controlled Martissant, Village de Dieu, Grande Ravine, Bel Air, Cité Soleil, Fort Dimanche, and many other areas in Port-au-Prince.

[23] Human rights groups and victims have described the G9's tactics to include random killing of civilians, systematic rape, looting and torching villages, kidnapping, dismemberment and more.

[27][29] Chérizier publicly demanded Moïse's resignation from office a week before the assassination, calling for a "national dialogue" to redefine Haiti.

[30] In the aftermath of the assassination, Chérizier publicly mourned Moïse, including leading a crowd of more than 1,000 demonstrators calling for justice against the perpetrators.

After Henry requested foreign military aid to end the blockade, Chérizier changed his demands, to receive amnesty for arrest warrants issued for crimes allegedly committed by himself and other G9 members.

[34] In March 2024, Chérizier claimed responsibility for orchestrating attacks that led to the escape of over 4,700 inmates from Haiti's two largest prisons and killed around a dozen people.

[38] Francisco Uribe, one of the few detainees who chose not to leave prison, said in a video posted to social media that "They are massacring people indiscriminately inside the cells".

[41] The Associated Press reported that the G9 Family and affiliated gangs controlled around 80% of the capital city and were launching coordinated attacks on "once unthinkable targets like the Central Bank".

[42] Amid the growing unrest, Chérizier declared former Haitian dictator François Duvalier as an inspiration and warned that if the international community continued supporting the unelected Ariel Henry, a full-scale civil war would be inevitable.

[45] In an October 2024 interview with the journalist Michael Deibert, Chérizier asked for the Kenyan-led "multinational force to leave the country, because it is a group of invaders who just came under the orders of the United States, Canada, and France.
