The US National Counterterrorism Center is pleased to present the 2014 edition of the Counterterrorism (CT) Calendar. This edition, like others since the Calendar was first published in daily planner format in 2003, contains many features across the full range of issuespertaining to international terrorism: terrorist groups, wanted terrorists, and technical pages on various threat-related topics. The Calendar also marks dates that terrorists may believe are important if planning attacks to commemorate particular events.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 all been either indicted or are being sought for their involvement in international terrorism.The CT Calendar is designed as a ready reference guide for law-enforcement, intelligence, military and security personnel, contingency planners, or citizens concerned about terrorist threats. The CT Calendar is oriented primarily to readers in the United States, but we hope it will be useful for citizens of other countries as well.
