A top European Union leader has laughed off allegations that Germany's foreign intelligence service may have spied on his offices on behalf of the United States.

European Commission President Jean-Claude Juncker said Thursday that given the rumors of spies in Brussels, "the Commission should have a secret service." He said it is up to "the German authorities to deal with that, and I suppose that they will do so."

German media are reporting that the BND intelligence agency was asked by the U.S. National Security Agency to monitor telecommunications traffic in a way that might have gone against German interests. The Sueddeutsche Zeitung newspaper cited secret government documents claiming the targets included senior officials in France and at the EU Commission.
