President Barack Obama sought to allay concerns from German Chancellor Angela Merkel about reported U.S. spying on European allies on Wednesday, and they agreed to hold a high-level meeting on the subject in coming days. The European Union has demanded the United States explain a report in a German magazine that Washington was spying on its European allies, calling such surveillance shocking if true, according to a report of Reuters. A White House statement said Obama and Merkel spoke by phone, a conversation that took place two weeks after they held face-to-face talks in Berlin. "The president assured the chancellor that the United States takes seriously the concerns of our European allies and partners," the White House said, noting U.S. and EU officials would discuss intelligence and privacy issues as early as July 8. The leaders agreed to hold a meeting of U.S. and German security officials in the coming days to discuss the issue in greater detail.
