LONDON -- An American journalist working in Myanmar has been detained there by local authorities, according to his employer and his family. Frontier Myanmar, a Yangon-based news and business magazine that publishes in print and online in both English and Burmese, said in a statement Monday that its managing editor, Danny Fenster, was detained at Yangon International Airport in Myanmar's largest city as he was preparing to board a flight to Kuala Lumpur, Malaysia. He has since been transferred to Insein Prison in Yangon, which has housed thousands of political prisoners. "We do not know why Danny was detained and have not been able to contact him since this morning," Frontier Myanmar said. "We are concerned for his wellbeing and call for his immediate release. Our priorities right now are to make sure he is safe and to provide him with whatever assistance he needs." ABC News has contacted Frontier Myanmar for further comment.
