PORT-AU-PRINCE, Haiti (AP) — The Federal Aviation Administration is prohibiting U.S. airlines from flying to Haiti for 30 days after gangs shot two planes. The United Nations also said Tuesday that it temporarily suspended flights to the capital, limiting humanitarian aid coming into the country. Bullets hit a Spirit plane when it was about to land Monday in the country’s capital, injuring a flight attendant and forcing the airport to shut down. JetBlue and American Airlines said that their planes had also been shot while leaving the airport. The shootings were part of a wave of violence that erupted in Haiti as the country swore in its new prime minister after a politically tumultuous process.
