A German regional minister has said no explosives have been found so far and no arrests made after a Germany-Netherlands friendly football match was cancelled, due to a "serious" bomb threat.
The interior minister also told a press conference that rumours of an explosives-packed ambulance could not be confirmed.
The match in Hannover was due to begin at 7.45pm GMT but a security alert saw police step in at around 6pm to prevent it taking place.
The minister said the match, which Chancellor Angela Merkel had been due to attend, was cancelled "to protect the population", but did not provide specifics.
He said "we had good reasons, bitter reasons" but added that describing them could "cause concern to the population", after local police in Hanover earlier said there had been a bomb threat.
Earlier, German broadcaster NDR quoted Hannover police chief Volker Kluwe as saying: "We have had concrete evidence that someone wanted to ignite an explosive device at the stadium."
The German football federation (DFB) announced in a short Twitter statement: "The team are in a safe place. The match will not go ahead."
Its spokesman Jens Grittner wrote on Twitter: "We were on our way into the stadium and were diverted by the police to a safe place. We cannot say more at this time. Please understand."
Dutch newspaper Telegraaf said one suspicious package was found that was later shown to be harmless.
Announcing the cancellation, a stadium public address announcer at the Niedersachsenstadion said: "I'm sorry but the match has just been called off." The announcer said there was "no danger".
Germany were caught up in the attacks in Paris on Friday, with explosions heard outside the Stade de France during their friendly against France as suicide bombers detonated devices.
Attacks in the French capital have so far claimed at least 129 lives. Belgium's friendly against Spain, which was also due to be played on Tuesday, was cancelled on Monday night due to an increased terrorism threat.

World champions Germany had not initially wanted the game to go ahead after having played against France in Paris on Friday as a wave of attacks hit the city.
The contingent of 80 Germans - including players, coaches and staff - then spent the night holed up in the changing rooms of the Stade de France stadium as the attacks took place across the capital, before heading for the airport on Saturday morning.
But the players and coaches, as well as the national football association, then decided to go ahead with the game to show unity - before it was called off amid the latest terror threat.
