The rebels, in a letter to Prince Norodom Sihanouk, said they were 'leaving Phnom Penh . . . (because) they didn't feel secure,' said Eric Berman, a UN spokesman.
It was not clear whether the letter meant the Khmer Rouge was pulling out of the peace process altogether, Mr Berman said. 'Where they hang their hat is not a concern to us,' he said. 'The most important thing is if they're dropping out of the peace process.'
