BERLIN: Berlin's chief public prosecutor has extended an investigation into the release of a trove of documents by WikiLeaks to include the chancellery as well as the Bundestag lower house of parliament, broadcaster NDR said.
Last December, WikiLeaks released the confidential documents, which German security agencies had submitted to a parliamentary committee investigating the extent to which German spies helped the US National Security Agency (NSA) to spy in Europe.
