Police in Munich acknowledged Thursday that they know about a possible planned terrorist attack, as major cities around the globe continued to take safety precautions on New Year's Eve.

Two Munich trains stations — Hauptbahnhof and Pasing — were evacuated, police told NBC News. In a tweet, authorities asked people to avoid large crowds in the city, one of Germany's largest.

The nature of the threat and who made it were not immediately clear, but police said they were investigating potential suspects. They said they would provide updates on social media.
