Hurricane Matthew slammed into Haiti's southwestern tip with howling 145 mph winds Tuesday, knocking down trees and tearing off roofs in the poor and largely rural area, while inundating neighborhoods in floodwaters and mud.

By nightfall, at least 11 deaths had been blamed on the powerful storm during its week-long march across the Caribbean. But with a key bridge washed out, impassable roads and phone communication cut off with Haiti's hardest-hit area, there was no way to know how many people might be dead or injured.
