Eight people died in Haiti in the path of Tropical Storm Isaac, according to a preliminary report from emergency services officials.

Among the victims were three minors - a 10-year-old girl who died when a wall collapsed onto her home in Thomazeau, a boy struck by a falling tree in the capital suburb of Carrefour, and another boy who was electrocuted in the northern city of Gonaives.

Meanwhile, 14,375 people were evacuated in six provinces, of whom 13,561 are in shelters.

The two provinces hit hardest by Isaac are Ouest and Sud-Est, the government statement said.

In terms of infrastructure, the road across the Grand-Goave River in Ouest province was swept away by the waters, while bridges over the swollen Grise River on the outskirts of Port-au-Prince are under close watch.

Authorities also said the storm has inflicted considerable damage on housing and agriculture, while tearing the roofs off a good many homes in the Ouest, Sud-Est and Nord-Ouest provinces.

Isaac was blamed for at least two deaths in the Dominican Republic, which shares the island of Hispaniola with Haiti.
