Which agency assumes lead responsibilities for terrorist and high-risk incidents within US territories?

The Federal Bureau of Investigation (FBI) assumes lead responsibilities for terrorist and high-risk incidents within US territories. This agency has the authority and resources to respond to various types of threats, including terrorism. The FBI collaborates with other federal, state, and local agencies, utilizing its expertise in intelligence, investigation, and counterterrorism operations.

This leadership role is formalized under the National Response Framework, which assigns the FBI as the primary federal agency in charge when incidents of national significance occur. Their specialized teams, such as the Hostage Rescue Team and Evidence Response Teams, are vital in managing high-risk scenarios effectively and ensuring public safety.

While other agencies like the Department of Homeland Security and the Department of Justice support national security efforts, it is the FBI that directly leads the operational response during these critical incidents.
