A German magazine says the U.S. National Security Agency kept more than 300 reports on German Chancellor Angela Merkel, a revelation that could further strain relations between the two countries over the scope of U.S. surveillance programs.
magazine says the reports were part of a database
about foreign heads of state that also included the heads of Peru, Somalia, Belarus and other countries.
In a Saturday report, Der Spiegel
said the information is in documents leaked by former U.S. national security contractor Edward Snowden. The NSA says he stole 1.7 million documents before fleeing to asylum in Russia.
also says a British intelligence service infiltrated Germany Internet companies.
At an October summit in Brussels, Chancellor Merkel said she made it clear to President Barack Obama that spying on allies was unacceptable. She commented after allegations emerged that the NSA had monitored her cell phone calls.
In January, Obama outlined a series of changes to U.S. surveillance operations, including a plan that would virtually end spying on foreign allies.
