This is the latest in a series of reports from the Combating Terrorism Center drawing on newly released information from captured al-Qa’ida documents maintained in the Defense Department’s Harmony Data Base. The report is a preliminary analysis of records containing background information on foreign fighters entering Iraq via Syria over the last year. The data used in this report was coded from English translations of these records and undoubtedly contains some inaccuracies de to imprecise translation as well as through errors in the transcription process. The CTC plans further studies based on the Sinjar Records and expects to hone and improve the accuracy of our database as we do so.
