BANGUI - Violence in Central African Republic has uprooted nearly a million people, a fifth of the population, and is hampering aid efforts, particularly in the capital Bangui, the UN refugee agency (UNHCR) said on Friday.
A flare-up in violence between Muslim fighters and Christian militias has displaced more than 200,000 people in the past few weeks alone, leaving a total of 935,000 homeless.
A Muslim rebel group, the Seleka, unleashed a wave of killing and looting after seizing power in March, and the deployment of 1,600 French and nearly 4,000 African Union peacekeepers has done little to contain the tit-for-tat violence between religious communities.
In the riverside capital alone, more than 510,000 people are displaced - equivalent to more than half the city's population, UNHCR said. Just over half of them are children.
The number of people sheltering at a makeshift camp at the international airport has doubled in the past week to 100,000. The site lacks proper access to food or water but access for humanitarian groups has been restricted by fierce fighting in nearby neighborhoods.
"Insecurity and chaos around the site...prevents us from doing any distribution," UNHCR spokesman Babar Baloch told a news conference in Geneva. "It's a horrible situation. We have heard a lot about revenge attacks happening inside health centers, where armed elements have gone and attacked patients."
Medical charity Medecins Sans Frontieres said it was cutting services to a minimum at its airport clinic after stray bullets killed three children and injured 40 people this week.
"We are not going to continue to put the lives of our personnel at risk," Lindis Hurum, its coordinator at the site, told Reuters. "A team composed of five of our 16 doctors will be left in place for cases of extreme emergency."
Many of the displaced and injured inside the airport camp voiced fear that they were being abandoned.
"I owe my life today - like hundreds of others here - to MSF. But with this suspension of their activities, it will be a massacre," said Saint Cyr Lamaka, one of the wounded receiving treatment.
