UN troops are guarding food distribution centres in Haiti

Calixte Valentin, mayor of Gonaives, said bodies were still being found, 10 days after the storm.

The United Nations has warned that the situation in the city is "critical".

Relief workers say food is still not getting to people quickly enough, amid problems with security and logistical problems caused by the storm.

The official death toll from the flooding is at least 1,514 across the island, but more than 900 people are still unaccounted for.

"It's sad but true that the missing will slowly be started to be counted among the dead," said Brazilian Army Gen Augusto Heleno Ribeiro Pereira, in charge of the United Nations peacekeeping force in Haiti.

Fighting

Many residents in Gonaives have not had food for a week.

Dr Jose Manuel Aguilar: No clean water

The UN troops have been mobilised to stop people fighting at food distribution points.

At the weekend, troops had to fire into the air to stop hungry people grabbing food from aid trucks.

A doctor from New York who has gone to help in his native Haiti, Jean-Claude Kompas, told the Associated Press news agency he had treated 30 people for gunshot wounds received in fights over food.

The city is still without electricity or running water, and lacks basic medicines such as antibiotics.

Volunteer doctors have spoken of appalling conditions as they try to help the storm survivors in makeshift clinics.

Amputations have been carried out under primitive conditions, many people have infected wounds, and there are widespread cases of diarrhoea.

"There's no clean water. There are no resources," Dr Jose Manuel Aguilar told AP at a tent hospital set up by Cuban and Venezuelan doctors.
