(BBC) The Nepalese army has condemned a study linking its United Nations peacekeepers in Haiti to a cholera epidemic there.
The disease has so far killed more than 2,000 people.
A spokesman for the army in Kathmandu said there was no concrete evidence to support the allegation.
He said the Nepalese base in Haiti had been tested three times and no cholera had been found.
Sources say a study by a French medical professor found that the cholera outbreak in Haiti was an imported strain, and began at a base housing the Nepalese forces.
Last month UN peacekeepers used teargas to break up angry protests by Haitians who blamed them for the epidemic.
