The head of Germany's domestic intelligence service resigned on [July 2] after admitting that his agency had shredded files on a neo-Nazi cell whose killing spree targeting immigrants rocked the country late last year. Heinz Fromm's resignation is the latest in a series of embarrassing setbacks for Germany's security services over their handling of the National Socialist Underground" (NSU), which went undetected for more than a decade despite its murder of 10 people, mostly ethnic Turkish immigrants. German lawmakers said there was no suggestion that Fromm had ordered the destruction of the files but that he was taking responsibility for others' failures. German media have said an official working in the intelligence agency is suspected of having destroyed files on an operation to recruit far-right informants just one day after the involvement of the NSU in the murders became public. Fromm told the Spiegel weekly that the shredding of files in the case had done "grave damage to the reputation" of his agency, known in Germany as the Federal Office for the Protection of the Constitution. Germans, burdened by their Nazi past, were mortified by last year's news that three neo-Nazis had been behind the killings of eight ethnic Turks, an ethnic Greek and a police officer in a period running from 2000 to 2007. The NSU cell's culpability only came to light after two of the neo-Nazis committed suicide following a botched bank robbery last autumn.
