Ethnic Karen refugees from Myanmar walk at the Mae La camp outside Mae Sot near the Thai-Myanmar border October 14, 2010. Ethnic Karen refugees continue to pour into Thailand, fleeing decades-long fighting between Karen rebels and Myanmar government troops and its guerrilla allies. Some 140,000 refugees live in official camps along the Thai-Myanmar border, according to the U.N. refugee agency and there are concerns that hostilities in the hills of Eastern Myanmar could intensify as a result of a refusal of several ethnic political groups to take part in an election next month.
