Four UN staffers and two pilots were killed in a plane crash in Bolivia, where they were monitoring cocaine production, officials in La Paz and New York said Saturday.
The small Cessna crashed Thursday some 200 kilometres north-east of the capital, La Paz, and was found Saturday, the Bolivian air force said.
The UN said the staff were part of the UN Office on Drugs and Crime and were Bolivians, DPA reported.
The flight was to have surveyed coca producing regions of the country.
