UNITED NATIONS - UN humanitarian aid chief Valerie Amos and UN special envoy to Libya Abdelilah Al-Khatib will go to Tripoli in the coming days to assess the impact of the fighting, Amos' deputy said on Thursday.UN assistant secretary-general and deputy emergency relief coordinator Catherine Bragg told a briefing for the 192 UN member states that some 250,000 people had fled Libya for neighboring countries as forces loyal to leader Muammar Gaddafi step up their attacks against rebel fighters.Most of the refugees -- over 137,000 -- had gone to Tunisia and the majority of them are foreigners, she said."Humanitarian agencies are working tirelessly to avoid bottlenecks at the borders, and to ensure that those waiting in transit camps do so in a dignified manner," she said, according to a written copy of her speech.
