Odaily Planet Daily reported, citing CNN through Jinshi, that the incident involving the U.S. Department of Defense was triggered by a false alarm. The brief update described the nature of the event as a “false alarm,” but did not provide further details on what caused the alert, how the situation was handled, or when normal conditions resumed.
Earlier information had stated that the Pentagon had been locked down and that a hazardous materials response team was heading to the scene. With the later CNN update, the report shifted from an active on-site response to an incident attributed to a false alarm. The available dispatch includes only this sequence of events and does not mention casualties, confirmation of hazardous materials, or any additional official explanation.
