Laos: Well-known aid worker disappears in Laos

The work of Sombath Somphone is well-known across southeast Asia, but his disappearance in Laos on December 15 is a mystery. It was Sombath's development work and help to poor farmers that won him one of Asia's most prestigious civil service awards. Laos authorities told Sombath's wife that they don't have him; they say he might have been kidnapped for personal or business conflicts and an investigation is underway.
