Damnak Chang'aeur (Central Khmer: ដំណាក់ចង្អើរ, UNGEGN: Dâmnăk Châng'aeur in Central Khmer pronounced as /ɗɑmnak cɑŋʔaə/) is a district (srok) in Kep Province, Cambodia. It is the largest district in the province and a train track from Phnom Penh to Sihanoukville runs through here. The district is subdivided into three communes (khum) and 11 villages (phum).[2]
In June 1994, Phnom Voar in Damnak Chang'aeur hit the international headlines as the site of the kidnapping of three westerners, Australian David Wilson, 29, Briton Mark Slater, 28, and Frenchman Jean-Michel Braquet, 27 from a train by Khmer Rouge forces led by Commander Chouk Rin.[3]
