French President Rejects Possible Intervention in Central African Republic
Has enough to worry about with Mali
There is a mood of deep anxiety in the capital of the Central African Republic, Bangui, as rebels advance towards the city, a UN envoy has said.
Margaret Vogt told the BBC she had seen that residents of Bangui were "petrified as to what could happen".
The UN is now evacuating its non-essential staff from the country, while the US urged its nationals to leave.
France has ordered tighter security of its embassy in Bangui after it was attacked by protesters.
