More than 100 Democrats from the US House of Representatives have called on the UN to take responsibility for introducing cholera to Haiti.
It is the latest twist in the allegation that UN peacekeepers unwittingly introduced the disease.
The United Nations’ envoy to Haiti, Bill Clinton, has accepted UN soldiers may have brought cholera.
But with more than 7,000 deaths so far, the UN said tackling the disease is more important than attributing blame.
