Police in the German city of Munich are maintaining a heightened presence following warnings of a planned attack on New Year's Eve.

Two Munich train stations were evacuated late Thursday after German authorities received information from foreign intelligence agencies that five to seven Islamic State militants were planning coordinated attacks in the city.

A German security official, speaking on condition of anonymity because he wasn't authorized to divulge the information publicly, said the key tip came from French authorities shortly before 8 p.m. local time.

Munich police spokesman Sven Mueller said descriptions of the alleged attackers included several "common Arab names" but that they could be false.

He said up to 200 additional officers are patrolling the streets Saturday to spot any suspicious activity and reassure the population.
