Germany's foreign intelligence chief has warned that Russia could seek to disrupt next year's German elections with cyber attacks.
Bruno Kahl said his agency was aware of cyber attacks with no other purpose than "causing political uncertainty".
"Europe is in the focus of this attempted disruption, and Germany in particular," he told Sueddeutsche Zeitung.
Russia or groups linked to Russia have been regularly accused of such attacks.
Campaigning has yet to start for federal elections in autumn 2017 but Angela Merkel announced last week she would be seeking a fourth term as chancellor.
