Authorities say hackers have tried to break into the internal data system of the German Parliament.

Ernst Hebeker, a spokesman for Parliament, told the dpa news agency Friday that there was an attack on the internal data systems and that specialists were working on the issue. He refused to give any further details.

The weekly Der Spiegel's website reported that information technology specialists were aware of the attempt several days ago and that members of parliament had been informed on Friday morning. It reported that it was not clear whether any had been accessed.
