The violence has worsened a devastating humanitarian crisis in the Caribbean nation of 11 million. Almost half of the population suffers from acute hunger. Conditions deteriorated further this month when the gangs, which usually battle one another, joined together to attack two prisons, the international airport, the principle seaport and several police stations.

The Haitian presidency has been vacant since Moïse’s killing; the last lawmakers’ terms expired last year. That left Ariel Henry, the deeply reviled prime minister appointed by Moïse days before his assassination, in charge — until the recent violence prevented him returning home from a trip to Kenya. He had traveled to the African nation to finalize an agreement for a U.N.-approved, Kenyan-led security mission for Haiti.

Henry, who has long drawn criticism for failing to stem the violence and for reneging on promises to hold elections, said this week that he would resign once a transitional presidential council and interim prime minister were put in place. But it’s unclear whether Haiti’s quarreling factions will be able to put aside their differences to stand up the council and reimpose order.
