WASHINGTON - The US government will respond through diplomatic channels to demands from the European Union that Washington explain a report in a German magazine that Washington is spying on its European allies."We will also discuss these issues bilaterally with EU member states," a spokesperson from the Office of the Director of National Intelligence said on Sunday. "While we are not going to comment publicly on specific alleged intelligence activities, as a matter of policy we have made clear that the United States gathers foreign intelligence of the type gathered by all nations."Demands for clarification from Europe came after a report in Der Spiegel magazine that the United States had tapped EU offices in Washington, Brussels and at the United Nations.
