The Boston Globe:

Information obtained through the interrogation of a Guantanamo Bay detainee led to a spectacular series of counterterrorism raids in Germany this month, in which more than 700 police swept through mosques, homes, and businesses in six cities and arrested 22 suspected militant extremists, according to a senior Defense Department official. The role of the Guantanamo interrogations in triggering the raids had not been previously reported. In Europe, the interrogations have been widely denounced as flagrant violations of international law, and many leaders have expressed concern over alleged abuses.
