FILE - In this March 5, 2013 file photo German flags fly in front of the Reichstag building, host of the German Federal Parliament Bundestag, in Berlin, Germany. A top police official says a recent hacking attack on the German Parliament may have led to a "significant drain of data" which may be used to try influence the outcome of the country's general election in September. Holger Muench, the head of Germany's Federal Criminal Police Office, didn't tell reporters Thursday, March 30, 2017 who might have been behind the most recent hacking attack. The offices of at least 10 members of Parliament were attacked last month, the German news agency dpa reported. (AP Photo/Michael Sohn,file)
