BERLIN (AP) — Police say two small planes have collided over northeastern Switzerland, injuring seven people.

St. Gallen canton police said the aircraft both were able to make emergency landings after the collision Sunday afternoon — one in a field and the other at an airfield.

It wasn’t immediately clear how badly they were damaged, but a police statement said pieces of wreckage crashed into a local company’s premises.

The pilot and three passengers aboard the plane that landed in the field were seriously injured. The pilot of the other plane and its two passengers also were injured.

There was no word on the cause of the collision.
