Triggered by unusually humid weather, the tornado hit the campsite in the Aalen area in the state of Baden-Württemberg. It ripped up two large tents belonging to a local diocese, and damaged eight others. Roofs came off five buildings and trees were uprooted.
There were around 100 children and adults at the campsite, 27 of whom were injured badly enough to need medical help.
One 10-year-old girl had such bad back injuries that she was taken to a Stuttgart hospital by air ambulance. Five others, including three supervising adults, also sustained more serious injuries – mostly broken arms.
The tornado caused an estimated €200,000 of damage to the site. Those who were not physically injured were looked after in a local sports hall, where they were treated for shock.
