Army starts destroying largest US stockpile of chemical weapons

The process of destroying America’s largest remaining stockpile of chemical weapons began on Wednesday in Colorado, more than a decade after the Defense Department approved the destruction of 780,000 shells containing 2,600 tons of mustard agent.

It will take four years to destroy the inventory leftover from World War II at Pueblo Chemical Depot in southern Colorado.
