Joseph Edgard Celestin of the Haitian government says that the death toll has risen from Tropical Storm Isaac.

The official from Haiti's Civil Protection Office said Sunday that the number of people who died in the Caribbean nation is now up to seven after an initial report of four.

Celestin had few details about how the people died. But he said one man was swept away as he tried to cross a river in the north of the country.

Impoverished Haiti is prone to flooding and mudslides because the bulk of the country is heavily deforested and rainwater rushes down barren mountainsides.

The center of Tropical Storm Isaac passed Haiti's southern peninsula early Saturday and caused flooding in the capital and elsewhere but no major damage.
