A draft report commissioned by the United States government suggests far fewer people died in the Haiti earthquake that the Haitian government reported.
The latest report puts the number of dead after the 7.0-magnitude quake in January last year at between 46,000 and 85,000 people.
The Haitian government says 316,000 died and is standing by the figures it released last year.
If confirmed the new lower figure could challenge the need for the multi-billion dollar aid effort the Haitian government has been calling for, the BBC reports.
A spokesperson for the US government said the report was not yet ready to be released, as there were still some internal inconsistencies.
