Chiha-ri Chemical Corporation
The Chiha-ri Chemical Corporation in Anbyon, also known as the Chiha-ri Materials Corporation, south of Wonsan, is said to be one of at least two primary chemical weapons storage facilities, with the other being located at Masan-dong. This facility is said to consist of numerous underground storage tunnels dug into mountains. The tunnels reportedly contain filled warheads, bulk agents stored in large tanks, as well as chemical warfare protection gear, detection equipment, and decontamination materiel. Some reports suggest that the facility is also used for biological weapons.
