The UN Resident and Humanitarian Coordinator in Burma Ashok Nigam called for the release of four UN employees who have been detained in Arakan State for more than a year. The Burmese workers were being subjected to “arbitrary arrest and detention” Nigam said in a statement released on the occasion of World Humanitarian Day on Monday. “The freedom of these four humanitarian workers is long overdue,” he said. Burmese authorities arrested about a dozen Muslim aid workers employed by international aid groups last year after they interacted with villagers affected by inter-communal violence in the state. Most were released after several months.
