BERLIN (AP) — A fire department spokesman says two planes have collided in the air at an airshow in northern Switzerland and that at least one of the planes crashed after the impact.

Marco Thomas of the Laufental fire department said Sunday that the two planes touched each other in mid-air just before the crash in the village Dittingen near Basel. He did not have any further information about possible injuries or casualties.

Daniel Fierchter, a spokesman for the Dittingen airshow, also confirmed the crash and said that rescue teams had just arrived at the scene.

On Saturday, seven people died after a military jet participating in an airshow in the UK crashed into a busy road.
