Hannover's chief of police says authorities received a warning about a possible bomb threat shortly before the start of a soccer friendly match between Germany and the Netherlands in the main Hannover stadium.

The stadium was evacuated and the game was canceled.

Police chief Volker Kluwe told German public broadcaster NDR that the alleged threat involved the "detonation of explosives in the stadium."

He says the "key warning reached us about 15 minutes before the gates opened."

Germany's national soccer squad said the team was taken to "a safe place" by police.

Germany's interior minister was holding a news conference later on the twin evacuations.

Announcements at the stadium in northern Germany advised people to go home in a calm manner, and that there was no danger to fear.

Most fans were still waiting outside when the order to evacuate came about an hour and a half before kickoff.

There were no signs of panic, with most fans seemingly accepting the decision with resignation.

Police became more forceful with members of the media who attempted to stay beside the stadium.

Members of the German government including Chancellor Angela Merkel were scheduled to attend the match to send a signal that Germany wouldn't bow to terrorism in the wake of the Paris attacks.

Security was very tight, with police armed with machine guns surrounding the stadium and maintaining a very obvious presence in the city.

Reporters arriving for the game were searched, while a sniffer dog was deployed to check their bags.

No reason was immediately given for the cancellation, but news agency dpa reported there had been a threat of an "impending attack that had to be taken seriously."

There had also been a bomb threat about an hour earlier outside the stadium. Streets leading to it had been sealed off before the all-clear was given.
