Terrorism: Commentary on Security Documents is a series that provides primary source documents and expert commentary on the worldwide counter-terrorism effort. Among the documents collected are transcripts of Congressional testimony, reports by such federal government bodies as the Congressional Research Service (CRS) and the Government Accountability Office (GAO), and case law covering issues related to terrorism. Most volumes carry a single theme, and inside each volume the documents appear within topic-based categories. The series also includes a subject index and other indices that guide the user through this complex area of the law.Volume 122, U.N. Response to Al Qaeda--Developments Through 2011, discusses recent actions by the United Nations in response to Al-Qaeda, particularly focusing on sanctions under Security Council Resolution 1267 as well as regional responses and court challenges to 1267 sanctions. The documents introduced by Kristen Boon include the key Security Council resolutions, EU regulations, court decisions, and reports by Security Council committees and external bodies.
