German police have ordered an evacuation of the Rock Am Ring festival in Nurburg, Germany due to a “terrorist threat.” 

Variety reports that several leads hinted at a real threat. Rammstein was scheduled to headline the first day, but ended up not playing due to the evacuation.

“As safety is paramount, and it is necessary to exclude a threat to festival visitors in any case as far as possible, it was decided to suspend the festival for this day,” police said.

“After a threat could not be ruled out, all necessary measures were taken immediately. This led to the event being interrupted today for security reasons,” they added.

The organizers released a statement saying: “Due to a terrorist threat the police have advised us to interrupt the festival.

“We ask all festival visitors to leave the festival site in a calm and controlled manner towards the exits and camping grounds. We have to support the police investigations.
