A mass panic at the love parade in Duisburg killed at least 15 during a stampede in a tunnel. the festival was decided to run on to avoid another, even bigger panic when breaking off too abruptly. Instead, people left in small groups, with many still partying and not even knowing what was happening.
The inner town of Duisburg currently faces pure chaos due to masses of people trying to move out. The central train station has broken down. Cellphone networks also collapsed.
