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.'

All U.S. airlines and other commercial operators have been banned from flying into Haiti for at least 30 days, the Federal Aviation Administration announced Tuesday.
