9 Most Horrendous Chemical Weapons

5. Sarin

Sarin is well known these days, due to its use in recent attacks on civilians.

It is a class of chemical weapons called nerve agents which work by catastrophically interrupting the nerve signals that help the body to function. It is colourless and odourless and a pinprick sized drop is enough to kill a fully grown adult. It causes victims to rapidly lose control of all bodily functions, including bladder, bowels and respiratory system, as well as bringing about convulsions and paralysis as nerve signals are interrupted.

The deadly chemical was infamously released on the Tokyo subway in 1995, in an attack that killed 13 people, and on the city of Halabja in 1988 by Saddam Hussein massacring as many as 5,000 people, most of which were civilians, making it the biggest chemical weapons attack against civilians in human history. It was most recently used in Ghouta, Syria in 2013, with an estimated death toll of at least 281 people to 1,729.
