Cholera victims sue UN for $2b New York: The United Nations has been sued for more than $2 billion by victims of a deadly cholera epidemic in Haiti that scientists say was caused by UN peacekeepers. In a lawsuit filed on Wednesday, the organisation was asked to pay compensation for the thousands of Haitians who have been killed or injured by the outbreak since October 2010. The epidemic caused about 8300 deaths and made more than 650,000 ill. The UN has refused to accept responsibility and said it cannot be sued because it is immune from such claims.
