Police said in a tweet that people should avoid crowds and train stations, according to CNBC.

As residents of the German city of Munich prepared to celebrate New Year’s Eve, police received concrete threats of a possible terror attack that night, reportedly connected to ISIS.

A suicide bomb threat by the so-called Islamic State of Iraq and the Levant (Isil) led to machine gun-toting police officers evacuating two of the city’s busiest train stations at 11pm on New Year’s Eve.

Referring to the Munich scare, Mr Herrmann said the authorities “have nothing concrete about a place or time”.

German officials said they were tipped off by a “friendly intelligence service” about the plan, which was to have been executed at around midnight, said Joachim Herrmann, interior minister for the southern state of Bavaria.

It has been reported that French intelligence agencies had notified Munich officials about the terror threat. While the stations have since reopened, Munich police are still on high alert and are carrying out more security checks that usual.

After half a day of panic, Germany finally lifted their alert over reports of an “imminent attack” in the Bavarian city of Munich, saying they had very concrete tips about a planned attack that ultimately never materialized.

The tips specifically referred to the two train stations, with the attacks planned for midnight.

Munich Police Chief Hubertus Andrae said although police had suspects’ names, they couldn’t be sure those people existed, or whether they were in Germany.

A Happy New Year to all!

The whole of Europe has been on edge following the November 13 Paris terror attacks that killed 130 people and injured many more.

“The situation in Europe and in Germany remains serious in the new year”, Thomas de Maizière, the interior minister, said in a statement Friday. Belgian police said late Thursday that three people were being held for questioning as part of an investigation into an alleged plot.

Numerous world’s major cities deployed increased security measures ahead of News Year’s celebrations amid mounting fears of terror attacks.

Police spokesman Werner Kraus told The Associated Press that “after evaluating the situation, we started evacuating the train stations and also asked partygoers to stay away from big crowds outside”.
