Gunfire hit a Spirit Airlines flight to Haiti on Monday, injuring a flight attendant, as the State Department warned of “gang-led efforts” to halt travel to the country.

Spirit confirmed in a statement that one of its flights from Fort Lauderdale, Florida, to Port-au-Prince, Haiti, was diverted to the Dominican Republic on Monday. It said an inspection of the aircraft showed damage consistent with gunfire.

“A flight attendant on board reported minor injuries and is being evaluated by medical personnel,” the statement said. “No guest injuries were reported.”

Spirit said it was suspending service to Haiti pending an “evaluation” of the incident and that the plane was grounded for the time being. A return flight to Florida is being arranged for crew members and passengers who were diverted to the Dominican Republic.

American Airlines said in a statement that it is also suspending service from Miami to Port-au-Prince.

“We will continue to monitor the situation with safety and security in mind and adjust our operations as necessary,” the statement said.

JetBlue’s website said The airline was “anticipating disruptions in Haiti due to civil unrest” and was waiving cancellation fees Monday through Saturday.

The State Department said in an alert from the US Embassy in Port-au-Prince on Monday that it was aware of a pause in operations at the city’s airport.

“The US Embassy in Port-au-Prince is aware of gang-led efforts to block travel to and from Port-au-Prince, which may include armed violence and disruptions to roads, ports and airports,” the alert said.

The State Department advises against travel to Haiti, which is still in the midst of violent political unrest. Even domestic travel from the Caribbean is not recommended.

“You should consider your personal security situation before traveling anywhere in Haiti,” the embassy said. “Try to leave Haiti or travel to Haiti only if you believe it is safe to do so.”

Haiti was overtaken by armed groups fighting for control after a power vacuum it was left by the assassination of the democratically elected president Jovenel Moïse in 2021. Ariel Henry, the deeply unpopular prime minister at the time, assumed the role of president and failed to hold elections.

And when he again postponed this year’s elections, violence ensued as armed militias collapsed country in civil unrest and put the lives of civilians in danger.

Henry said in April that he will resign once other Caribbean nations and parties brokered a transitional government.
