UN agencies are planning for the possible arrival of 200,000 refugees in Sudan fleeing violence in Ethiopia over a six-month period, a UN refugee agency official said on Friday. 'Together with all the agencies we have built a response plan for about 20,000 people and currently we are at about 31,000 so it has already surpassed that figure,' Axel Bisschop told a Geneva briefing. 'The new planning figure is around 200,000.'
