10 Weirdest Weapons Used During World War II

9. The Plagues Of China - Infected Fleas Dropped By The Japanese

In one of the many horrendous acts carried out by the Japanese on the Chinese, their military "bombed" the city of Ningbo with fleas carrying the bubonic plague.

Bacteriologist Huang Ketai undertook extensive research into this supposed act during the 1990s and discovered that more 110 Chinese died from the plague - which was rife in Europe in the Middle Ages, when it killed millions of people, but has been largely controlled throughout the world ever since.

Yet the Japanese attempted to infect the Chinese population by dropping fleas into Ningbo city centre in November 1940. Within days, hundreds of Ningbo residents became infected with the disease because the strength of the plague had been artificially intensified by the Japanese.
