Two roller coaster trains crashed at a Legoland amusement park in southern Germany on Thursday, injuring at least 34 people, two of them seriously.
A train braked hard and another train crashed into it in Guenzburg Park, the German news agency dpa reported.
Three helicopters and the fire and rescue services have been dispatched to the scene.
It was not immediately known what caused the crash. It took place at the Fire Dragon roller coaster station, a park spokesman told dpa.
Last week a woman died in another roller coaster accident in Germany, at an amusement park in Klotten.
The 57-year-old woman fell from the roller coaster car while it was moving and died from her injuries. The cause of the accident has not yet been established.
