ISLAMABAD (Reuters) - Pakistani officials on Monday rejected a German newspaper report that the country's secret service spied on German security forces in Afghanistan. Without citing its sources, mass-selling weekly Bild am Sonntag reported on Sunday that Germany's BND foreign intelligence agency warned its interior ministry that Pakistan had spied on 180 German police officers deployed in Afghanistan to train locals. A Pakistani foreign ministry official, who asked not to be identified, described the report as "ridiculous" and "useless". Pakistan military spokesman Major-General Athar Abbas said the report was not worth commenting on. Bild am Sonntag said private telephone calls, messages to the German interior ministry, military mission orders and lists of police officer names had been intercepted, raising fears sensitive information could end up in the hands of the Taliban. Pakistan says it has sacrificed more than any other country that joined the US war on terror after the Sept 11, 2001 attacks on the United States.
