Berlin Police have halted the popular Rock am Ring music festival in western Germany over a "terrorist threat situation" and cleared the area so that an investigation can take place.
"The background is concrete evidence based on which a possible terrorist threat cannot be ruled out. Intensive investigations are currently being carried out," police in the city of Koblenz said on Friday evening, adding that they could give no further details.
"As security is our number one priority and any danger to festival-goers must be eliminated in every case, insomuch as that is possible, it was decided to suspend the festival for today," the police said.
On Friday evening, the regional state government also confirmed the terrorist threat and said that the festival has been halted for security reasons.
