Forty-seven people perished in the Haitian village of Cabaret, near Port-au-Prince, in flooding caused by Ike, officials said Sunday.
"Many homes were destroyed in Cabaret, and we have seen some bodies of children in the water," a journalist for UN radio who spent the night on the roof of his house told AFP.
Ike late Saturday plowed across the low-lying Turks and Caicos as a powerful Category Four storm, causing some injuries and extensive damage on the British territory and tourist haven, before weakening somewhat to a Category Three.
The hurricane also raked the southeastern Bahamian island of Great Inagua, toppling trees, blowing off roofs, causing an island-wide power failure and forcing many of its one thousand residents to seek refuge in shelters.
But the greatest concern was Haiti, where a humanitarian crisis deepened after four storms in three weeks left at least 600 people dead and hundreds of thousands in desperate need of food, clean water and shelter.
Hundreds of bodies were found in flood-prone Gonaives, a town of 350,000 in northwestern Haiti, after a five-meter (16-foot) wall of water and mud engulfed much of the town.
UN peacekeepers on Saturday evacuated several thousand residents from Gonaives, a local official said, but thousands more are still awaiting relief.
Some 650,000 Haitians have been affected by the flooding, including 300,000 children, and the task of delivering crucial aid has been complicated by dismal transport conditions, according to UNICEF. Officials said 200,000 people have been without food and clean water, many for four days.
"What has happened here is unimaginable," member of parliament Pierre-Gerome Valcine told AFP from Cabaret, 35 kilometers (22 miles) north of the capital Port-Au-Prince.
Massive flooding over the past week in the poorest country in the Americas has triggered a humanitarian crisis that was worsening by the day -- and prompted prayers from Pope Benedict XVI.
"I want to remember the dear population of Haiti, greatly distressed in recent days by passing hurricanes," Benedict told pilgrims on the Italian island of Sardinia.
Continuing stormy weather hampered relief efforts Sunday, when heavy rains led to the collapse of a key bridge which severed the only viable land route to Gonaives.
The bridge gave way overnight at the town of Mirebalais in central Haiti, forcing three trucks loaded with emergency supplies and bound for Saint-Marc, where thousands of desperate flood refugees from Gonaives were crowding into shelters, to turn back, according to a World Food Programme official.
Many bridges in other areas of Haiti have also collapsed, homes have been washed away and crops ravaged.
