PORT-AU-PRINCE, Haiti — Haiti’s international airport shut down temporarily Monday after gangs opened fire at a Spirit Airlines flight landing in Port-Au-Prince, the U.S. State Department and the airline said. The latest violence came as a new prime minister was sworn in.  The flight, headed from Fort Lauderdale to Port-Au-Prince, was hit multiple times by gunfire as it was set to land in Haiti’s capital, striking a flight attendant, who suffered minor injuries. Photos and videos obtained by The Associated Press show bullet holes dotting the interior of a plane. The flight was diverted and landed in the Dominican Republic, according to Spirit Airlines. It appeared to be part of what the U.S. Embassy called “gang-led efforts to block travel to and from Port-au-Prince which may include armed violence, and disruptions to roads, ports, and airports.”  In other parts of Haiti’s capital, firefights between gangs and police broke out. Rounds of gunfire echoed through the streets as heavily armed officers ducked behind walls and civilians ran in terror. In other upper-class areas, gangs set fire to homes. Schools closed as panic spread in a number of areas. The turmoil comes a day after a council meant to reestablish democratic order in the Caribbean nation fired the interim Prime Minister Garry Conille, replacing him with businessman Alix Didier Fils-Aime. The council has been marked by infighting and three members were recently accused of corruption. On Monday, suit-clad diplomats and security officials flocked to the swearing-in ceremony, set to take place in the afternoon. The country has seen weeks of political chaos, which observers warned could result in even more violence in a place where bloodshed has become the new normal. The country's gangs have long capitalized on political turmoil to make power grabs, shutting down airports, shipping ports and stirring chaos. The transitional council was established in April, tasked with choosing Haiti’s next prime minister and Cabinet with the hope that it would help quell violence, which exploded after Haitian President Jovenel Moise was assassinated in 2021. The council was meant to pave the way to democratic elections, which haven’t been held in years in Haiti. Gangs have capitalized on that power vacuum to make their own power grabs. But the council has been plagued with politics and infighting, and has long been at odds with Garry Conille, the interim prime minister they handpicked six months ago, who they fired yesterday. Organizations including the Organization of American States tried and failed last week to mediate disagreements to save the fragile transition. 

PORT-AU-PRINCE, Haiti — The Federal Aviation Administration announced Tuesday that it will prohibit U.S. airlines from flying to Haiti for 30 days after gangs shot a Spirit Airlines flight. The United Nations also said it will suspend flights, "obviously limiting the flow of humanitarian aid and humanitarian personnel into the country."  The bullets hit the plane when it was about to land Monday in the country's capital, Port-au-Prince, injuring a flight attendant. It was part of a wave of violence that erupted in Haiti as the country swore in its new prime minister after a politically tumultuous process.  Life in much of Haiti's capital was frozen after the wave of violence, which came to a head when gangs shot the Spirit Airlines airplane Monday, forcing the airport to shut down. Photos and videos obtained by The Associated Press show bullet holes dotting the interior of a plane. A number of airlines suspended flights to Haiti through Thursday, but it was unclear how long closures could drag on.  Neither the former interim prime minister, Garry Conille, nor the newly inaugurated Alix Didier Fils-Aime commented on the violence.  But Luis Abinader, who as president of the neighboring Dominican Republic has cracked down on Haitian migration, called firing on the airplane terrorism.  "This was a terrorist act; the countries that are following and helping Haiti should declare these armed gangs as terrorist groups," Abinader said in a news conference.  On Tuesday, heavily armed police in armored cars outside the airport checked trucks used for public transportation passing by.  Schools were closed, as were banks and government offices. The streets, where just a day before gangs and police were locked in a fierce firefight, were eerily empty.  The sound of heavy gunfire was heard in the streets in the afternoon — a reminder that despite political maneuvering by Haiti's elites and a strong push by the international community to restore peace, the country's toxic slate of gangs kept its firm hold on much of the Caribbean nation.  The United Nations estimates that gangs control 85% of the capital. A U.N.-backed mission led by Kenyan police to quell gang violence struggles with a lack of funding and personnel, prompting calls for a U.N. peacekeeping mission.

The majority of U.S. airlines don't pay their flight attendants until the airplane door closes, even though plane boarding is one of the most stressful parts of their job.
