GENEVA (Reuters) - Up to one million Ivorians have now fled fighting in the main city Abidjan alone, with others uprooted across the country, the UN Refugee Agency (UNHCR) said Friday as violence escalated in a 4-month power struggle.
Hours ahead of a U.N. Security Council debate, France announced it had submitted a draft U.N. resolution banning the use of heavy weapons in Abidjan. The United Nations has accused forces loyal to incumbent Laurent Gbagbo of such attacks, which his camp strenuously denies.
"The massive displacement in Abidjan and elsewhere is being fueled by fears of all-out war," UNHCR spokeswoman Melissa Fleming told a news briefing in Geneva.
"Available estimates are that between 700,000 and one million could now be displaced," Fleming told reporters.
Ivory Coast has descended to the verge of civil war following a disputed election in November last year which Alassane Ouattara is recognized internationally to have won. Gbagbo has refused to step down, saying the results were rigged.
The violent stand-off has led to 462 confirmed deaths.
The U.N. agency said those leaving were mainly residents from the districts of Abobo, Adjamame, Williamsville and Yopougon, some of the most populated areas of Abidjan, a city of more than 4 million inhabitants.
"Families fleeing areas of conflict have told UNHCR monitors that they are afraid of being caught in the fire and killed by stray bullets," Fleming added.
A U.N. human rights officer said Thursday forces loyal to Gbagbo shelled areas seen as pro-Ouattara, and had killed 50 people in the past week. Gbagbo's camp has denied such attacks.
MEDICAL STAFF FLEE ABIDJAN
Leaders of Ivory Coast's neighbors called Thursday for the mandate of the 12,000-strong U.N. peacekeeping mission to be strengthened so it can more robustly prevent civilian deaths. The world body is mindful, however, that a more forceful engagement could also lead to an escalation in the fighting.
At an EU summit in Brussels, French President Nicolas Sarkozy told reporters France had submitted a draft resolution banning heavy weapons in Abidjan, days after the United Nations warned that pro-Gbagbo forces were readying an attack helicopter and rocket launchers. Gbagbo's government has repeatedly accused the U.N. of bias and siding with rivals it calls "terrorists."
"At a minimum there should be no heavy weapons in Abidjan," Sarkozy said. "We're talking about helicopters, mortars that could shoot on the population. It should be declared illegal by the international community."
The medical charity Doctors Without Borders (MSF) said it had treated hundreds of people with bullet wounds and there were no signs of the situation improving as health staff, along with many Ivorians, were fleeing Abidjan. Nearly all medical workers in six hospitals have fled, it said.
"Health centers no longer operate -- or provide extremely limited services -- because medical staff have left, they lack drugs and medical supplies, and because some have been looted," said Renzo Fricke, MSF emergency coordinator.
Residents said people were continuing to flee Abobo -- scene of some of the worst fighting -- Friday morning following a night of sustained automatic and heavy weapons fire in the area.
"We could not sleep last night. We shut the windows but could hear the sounds of heavy weapons and were afraid," said Clementine Yao.
A Reuters reporter heard sporadic machinegun fire in the direction of Williamsville Friday.
"Greater measures to protect civilians and meet fundamental humanitarian needs in Ivory Coast are urgently needed," said a coalition of 32 international charities in a Friday statement.
"Hundreds of thousands of people are in urgent need of food and non-food aid, including medicine ... current provision of funding for humanitarian aid is already insufficient," it added.
It urged that more funds be made available to cope with the unfolding humanitarian crisis, the deployment of extra peacekeepers to protect civilians and the establishment of a commission of inquiry to investigate human rights abuses.
