Multiple floors of the Pentagon were evacuated earlier today following a reported incident involving hazardous materials. The evacuation and subsequent isolation of the building were triggered by a false alarm, according to CNN. Emergency responders from Arlington County investigated the situation, initially responding to a potential threat related to dangerous substances. The incident was reported around 6 PM Finnish time. No actual hazardous materials were found, and the building has since been cleared. Authorities are currently investigating the source of the false alarm that prompted the large-scale response. The situation caused temporary disruption but did not result in any injuries.
