Three people were killed and seven wounded during a shooting at a factory near the city of Lucerne, Switzerland.
Police said the incident happened at about 9am on Wednesday at the Kronospan wood processing plant in the town of Menznau. The BBC reports the shooting lasted a few minutes.
The killer, a man who had worked at the factory for 10 years, is among the dead.
Switzerland has one of the highest rates of gun ownership in the world - an estimated 2.3 million firearms, but such incidents are relatively rare.
However, a BBC correspondent said there are more domestic homicides and suicides with a firearm in Switzerland than virtually anywhere else in Europe, except Finland.
All Swiss males aged between 18 and 34 are obliged to do military service and are issued with assault rifles or pistols which they are supposed to keep at home.
Until recently, many kept their weapons even after completing their military service.
