The German government says it doesn't expect questions about its spy agency's cooperation with the U.S. National Security Agency to damage relations with Washington.

The government faces questions over reports that the Federal Intelligence Service, known by its acronym BND, may have known of or even helped U.S. spying on European companies and officials as long ago as 2008. German media have reported that the BND this week stopped sharing some internet surveillance data from a German spy station with the NSA — something that neither government nor spy agency would comment on.

Government spokeswoman Christiane Wirtz said Friday that German-U.S. relations are "marked by great trust" and consultations with Washington on questions from German lawmakers are "not something that will jolt German-American relations in any way."
