HANNOVER, Germany (FOX 11 / AP) - The soccer stadium in Hannover, Germany, is being evacuated and stadium loudspeakers say the game has been cancelled.
The stadium was hosting a match between Germany and the Netherlands. Many top German officials, including Chancellor Angela Merkel, were scheduled to attend the match to show they will not bow to terrorism.
German police have released seven people arrested near the western city of Aachen in connection with the investigation of the Paris attacks.
The dpa news agency quotes an unidentified police official as saying checks found that none had links to the attacks.
Germany's Interior Minister Thomas de Maiziere had earlier told reporters authorities acted on a tip that one of those arrested might be a key suspect, "but sadly it's not the man that everyone hoped it would be."
Germany's top security official says a Syrian passport found with one of the Paris attackers may have been false flag intended to make Europeans fearful of refugees.
Germany's interior minister, Thomas de Maiziere, told reporters in Berlin that it was "unusual that such a person was faithfully registered in Greece, Serbia and Croatia, even though we're usually pressing for registration to take place and lament that it isn't always done properly."
He said the multiple registrations by a person using the passport were "evidence that this was a trail that was intentionally laid, but it can't be ruled out at the moment that this was an IS terrorist who came to France...via Germany as a refugee."
Germany's top security official has downplayed possible links between arrests near the western city of Aachen and the investigation of the Paris attacks.
Police said SWAT teams arrested a man and two women in the town of Alsdorf on Tuesday after authorities received a tip from the public that the man might be Salah Abdeslam, a key suspect sought in the attacks. Police later arrested two more persons in the town.
Interior Minister Thomas de Maiziere told reporters in Berlin that it wasn't clear how the people might be linked to the Paris attacks, if at all, "but sadly it's not the man that everyone hoped it would be."
Austrian authorities say Abdeslam entered Austria from Germany on Nov. 9 - four days before the attacks - with two companions.
French officials say they are seeking a second fugitive directly involved in the Paris attacks.
Three officials, who spoke on condition of anonymity because they were not authorized to provide details about the ongoing investigation, said Tuesday that an analysis of the series of attacks on Nov. 13 indicated that one person directly involved was unaccounted for.
Seven attackers died that night - three around the national stadium, three inside the Bataclan concert venue, and one at a restaurant nearby. A team of gunmen also opened fire at a series of nightspots in one of Paris' trendiest neighborhoods.
French and Belgian authorities have issued a warrant for one person, Salah Abdeslam, whose brother was among the attackers. The officials say the second fugitive has not been identified.
