The FAA banned flights to Haiti because a Spirit Airlines plane was shot at while it was trying to land in Port-au-Prince, Haiti's capital, and one flight attendant was injured.

The United Nations said it will also suspend flights, 'obviously limiting the flow of humanitarian aid and humanitarian personnel into the country.'

A Spirit Airlines flight from Florida was damaged by gunfire en route to Haiti and diverted to the neighboring country of the Dominican Republic, the airline said.
