Speakers accused the U.S. forces of introducing bio-chemical weapons and testing them according to the "Jupiter plan" from 2013.

The U.S. forces have posed a serious threat to the lives of the south Korean people through the introduction of anthrax germs but they covered up the fact and are evading the responsibility for it, the speakers noted.

They called for thoroughly probing the truth behind the U.S. forces' introduction of anthrax germs and severely punishing those responsible for it.

The organization read out a protest letter demanding the U.S. chief executive make apology for abusing the human rights of the south Korean people through the introduction of anthrax germs, the U.S. forces probe the truth behind the anthrax germ experiment and revise the humiliating SOFA. The organization thrust the protest letter to the U.S. embassy.
