U.N. Secretary-General Ban Ki-moon has arrived in Haiti to see firsthand a sliver of the extensive damage and destruction left by Hurricane Matthew.

Ban was greeted Saturday by Prime Minister Enex Jean-Charles after he stepped out of a U.N. jet at the airport in Haiti's capital of Port-au-Prince.

He then boarded a helicopter traveling to the storm-damaged southern city of Les Cayes, where he was to visit one of many schools serving as an emergency shelter for families who lost homes.

Matthew's eye made landfall Oct. 4 in a rugged region of southwest Haiti that's home to more than 1 million people.

Haitian authorities have reported that the death toll was 546, though it's likely to climb higher as reports continue to come in from remote areas.
