Libyan exodus ’ emergency’
THE UN refugee agency says a ‘‘ humanitarian emergency’’ is under way as thousands of foreigners flee Libya by air, land and sea. The agency said almost 100,000 migrant workers, mostly from Egypt and Tunisia, had fled Libya in the past week and many remained stranded at the Libya-Tunisia border as Libyan customs officers deserted their posts. ‘‘ We call upon the international community to respond quickly . . . to cope with this emergency,’’ said Antonio Guterres, the UN High Commissioner for Refugees.
