Chemical warfare

Chemical warfare is warfare using the toxic properties of chemical substances to kill, injure or incapacitate an enemy.

About 70 different chemicals have been used or stockpiled as Chemical Weapons agents during the 20th century.

Chemical weapons are classified as weapons of mass destruction by the United Nations, and their production and stockpiling was outlawed by the Chemical Weapons Convention of 1993.
