The US National Counterterrorism Center is pleased to present the Terrorism Guide Website. This site contains many features across the full range of issues pertaining to international terrorism: terrorist groups, wanted terrorists, technical pages on various threat-related topics, and a historic timeline that marks dates that terrorists may believe are important if planning attacks to commemorate particular events.
Under US law, NCTC focuses exclusively on international terrorism. There are other organized groups that engage in violent acts—some are criminal organizations with no political or social agenda, and some are domestic terrorist groups; however, this guide reflects NCTC’s international focus. Senior Intelligence Community officials assess the greatest international terrorist threats currently facing the United States come from violent extremists inspired by al-Qa‘ida, including its allies and affiliates, who are committed to conducting attacks inside the United States and abroad. These groups promote an ideology that presents a radical vision of Islam that is not followed or endorsed by the vast majority of Muslims.
Individuals portrayed in this calendar are all listed on the US Government’s Rewards for Justice site or on FBI sites devoted to terrorism. These individuals have been either indicted or are being sought for their involvement in international terrorism.
The Terrorism Guide is designed as a ready reference guide for law-enforcement, intelligence, military and security personnel, contingency planners, or citizens concerned about terrorist threats. The website is oriented primarily to readers in the United States, but we hope it will be useful for citizens of other countries as well.
In the conduct of intelligence activities, the Intelligence Community (IC) recognizes that it must protect fully the legal rights of all US persons, including freedoms, civil liberties, and privacy rights guaranteed by Federal law. The IC is not authorized to collect, retain, or disseminate information about US persons solely based on Constitutionally protected activities such as First Amendment speech, and may not do so based solely on race, religion, or other protected classification. All individuals in this calendar are included only because of information linking them to international terrorism. Individuals identified as charged or indicted with criminal wrongdoing are entitled to a presumption of innocence in the US court system, unless and until such time as they are deemed guilty through the judicial process.
