The US Program Executive Office, Assembled Chemical Weapons Alternatives said earlier on Thursday that the stockpile of chemical weapons stored at the US Army Pueblo Chemical Depot has been safely destroyed.
"The United States has announced the completion of destruction activities at its Pueblo Chemical Agent-Destruction Pilot Plant. In the coming weeks it is expected that the last declared chemical weapons stockpile in Blue Grass, Kentucky will be eliminated," the OPCW tweeted.
The organization added that its stringent verification regime gives the international community confidence in chemical weapons destruction results.
