Allegations of biological warfare in the Korean War
Allegations that the United States military used biological weapons in the Korean War (1950–53) were raised by the governments of People's Republic of China, the Soviet Union and North Korea. The claims were first raised in 1951. The story was covered by the worldwide press and led to a highly publicized international investigation in 1952.
