| has gloss | eng: Yellow rain was a political incident in which the United States Secretary of State Alexander Haig accused the Soviet Union of supplying T-2 mycotoxin to the Communist states in Vietnam and Laos for use in counterinsurgency warfare. Refugees described many different forms of attacks, including a sticky yellow liquid falling from planes or helicopters, which was dubbed "yellow rain". The Americans alleged that over ten thousand people had been killed in attacks using these chemical weapons. and these allegations are now generally regarded as false. Indeed, a 2003 review of the history of biological warfare described the "yellow rain" allegations as one of many cases where states have produced propaganda containing false or unsubstantiated accusations of the use of biological weapons by their enemies. The US government has not withdrawn these allegations. |
