SEOUL: North Korea has up to 5,000 tonnes of chemical weapons, South Korean experts said, including the toxin used to assassinate its leader’s half-brother.

South Korea’s Defence Ministry said in its 2014 Defence White Paper that the North began producing chemical weapons in the 1980s and estimated that it has about 2,500 to 5,000 tonnes in stock.
