Authorities in Munich have shut down two train stations and told people to avoid crowds if possible because of an "active threat of a terror attack."
The BBC cited local reports that information about the threats came from French authorities. Armed guards surrounded and evacuated the stations Thursday.
According to ABC News, off-duty officers were called in and began to perform sweeps of the evacuated stations. So far, they haven't found anything suspicious.
New Year's celebrations typically require extra security every year, but after attacks in Paris earlier this year, fears have been even more heightened. A fireworks display in Brussels was canceled Wednesday after news of possible attacks spread.
