BERLIN (Reuters) - Ukraine's prime minister blamed Russian intelligence on Thursday for a hacker attack against German government websites, for which a pro-Russian group claimed responsibility.

The attack on Wednesday took place before Prime Minister Arseny Yatseniuk was due to meet with German Chancellor Angela Merkel. The Russian group demanded Berlin end support for the Ukrainian government.
