NSA had over 300 reports on Merkel

German magazine Der Spiegel has reported that the U.S. National Security Agency kept more than 300 reports on Chancellor Angela Merkel in a special databank about scores of foreign heads of state, according to AP Sunday.

The magazine said Saturday the secret file about the surveillance of Merkel was part of a trove of documents obtained by former NSA systems analyst Edward Snowden.

Other leaders listed in the databank include the heads of Peru, Somalia, Guatemala, Colombia and Belarus.

Earlier this month, German lawmakers agreed to launch an inquiry into surveillance conducted by the NSA and other foreign intelligence services, including the tapping of Merkel's cellphone which was revealed in 2013.

German federal prosecutors are also mulling whether to open their own investigation into NSA activities.
