Geneva - The situation for refugees in the Georgian city of Gori is worrying, UN aid organization UNHCR said Tuesday.

"With 4,200 registered persons, the accommodation capacities are exhausted," UNHCR spokesman Ron Redmond said in Geneva.

About 450 arrived last week alone, fleeing looting militias, he said. "The militias are made up of armed men in uniforms without markings."

All of the refugees come from the so called buffer zone between Gori and the South Ossetia border, Redmond said.

Refugees told the UN organization that their homes were looted and set on fire. People who had stayed in their villages as the conflict first erupted were now fleeing too. Many of them had hid for two weeks before reaching the UNCHR camp.

Last month saw a brief but bloody conflict between Georgia and Russia over the breakaway Georgian regions of South Ossetia and Abkhazia. (dpa)
