Here is an overview of global arsenals of chemical weapons.
WHO HAS CHEMICAL WEAPONS?
According to the Organization for the Prohibition of Chemical Weapons, Albania, India, Iraq, Libya, Russia and the United States, along with a country identified by the OPCW only as “a State Party” but widely believed to be South Korea, have declared stockpiles of chemical weapons to the Hague-based organization that polices the treaty outlawing such weapons.
WHAT ABOUT SYRIA?
The OPCW, which has 189 member states, cannot check countries that are not party to the Chemical Weapons Convention for possible stockpiles. Syria does not belong to the convention but has now said it is joining. Other non-signatories include North Korea, Angola, Egypt and South Sudan. Israel and Myanmar have signed but not ratified the convention.
WHAT DO COUNTRIES HAVE IN THEIR STOCKPILES?
Between them, the seven signatory nations have declared 8.67 million chemical weapons-related items including containers and munitions and 71,196 metric tons of toxic chemical agents. Weapons include mustard gas and nerve agents like sarin and VX. Russia and the United States have the biggest stockpiles. The U.S. stockpile reached about 31,500 tons, according to the Army. Russia, by comparison, has said it amassed about 44,000 tons.
