Hurricane Melissa has caused devastating flooding in Haiti, leading to at least 20 deaths on the island. Many homes have been washed away in the floodwaters and people have been clearing debris with their bare hands, Pascal Bimenyimana from the World Relief NGO says.

The extent of the damage from Melissa was unclear Wednesday as widespread power outages and dangerous conditions persisted in affected areas.

Hurricane Melissa has strengthened into a major Category 4 hurricane, with the possibility of intensifying to a Category 5 storm Sunday night, unleashing torrential rain and threatening to cause catastrophic flooding in the northern Caribbean,

Hurricane Melissa made landfall in Jamaica as a Category 5 storm with wind speeds of up to 185 miles per hour.
