At least 1,941 have died in Haiti in Saturday’s powerful earthquake, a rise of more than 500 on the previous figure.
Rescue workers have managed to pull 34 people alive from the rubble but many are still missing after the 7.2-magnitude quake.
The search for survivors has been hampered by heavy rains brought this week by Tropical Storm Grace.
Nearly 10,000 people have been injured and hospitals were left overwhelmed.
The UN says about 500,000 children now have limited or no access to shelter, safe water and food.
Many have been staying in make-shift tents erected on a football field in the city of Les Cayes, one of the areas worst affected by the quake.
Haiti has been hit by a series of natural disasters in the past, including Hurricane Matthew in 2016.
The deadliest was the 2010 earthquake which killed more than 200,000 people and caused extensive damage to the country’s infrastructure and economy.
