Major accident in Haïti reported.
Fifty die as Haiti bus swept awayAbout 50 people have died in Haiti when their bus was swept away by a river gushing with rain dumped by Tropical Storm Fay, officials say.
Two dozen other people managed to escape as the bus sank in the Glace river in south-west of the country.
The storm is now moving over Cuba, bringing high winds and heavy rain.
Fay is forecast to strengthen to a possible hurricane as it heads towards Florida, where a state of emergency has been called.
Western and central areas of Cuba are being evacuated, as well as the Florida Keys.
The storm passed over Haiti at the weekend, bringing torrential downpours.
About 80 people were on board the bus that plunged into a swollen river on Sunday, officials said.
One report said the vehicle had overturned as it tried to cross a bridge over the Glace river near the town of Bomont in the south-western province of Grand-Anse.
Witnesses said many of those who died were swept away by the raging waters, while others, including about a dozen children, were trapped in the sunken vehicle.
"The river swept them away as if they were driftwood," Bomont Mayor Oreste Andre told the Reuters news agency.
Some two dozen survivors escaped by climbing onto the roof, he said.
Several other people were killed in Haiti and the neighbouring Dominican Republic as the storm caused floods on the island of Hispaniola.
