A man opened fire Wednesday morning at a wood processing company in Menznau, 45 miles southwest of Zurich, killing and severely injuring an undisclosed number of people. Police from nearby Lucerne were scant on details, but news agency SDA reported that four injured people were flown by helicopter to the nearest hospital.

Three people have been confirmed dead, according to the Swiss news site 20 Minuten, which posted images of the crime scene.

This is the second multiple-homicide shooting in typically calm but heavily gun-flush Switzerland this year. A 33-year-old gunman killed three women and injured two men on Jan. 3 in a shooting in the southern town of Daillon.

Such shootings are rare in Switzerland. In September 2001, Friedrich Leibacher, 57, opened fire in a regional parliament building in Zug, killing 14 people, according to the BBC, before killing himself. In the wake of that shooting measures to tighten Swiss gun control laws were rejected by the public. A second attempt was made in 2011, which was also defeated by referendum.

And for it's no wonder why: The Swiss love their guns.

“By car or by train, you see shooting ranges all over the country, but only a few golf courses,” attorney and Switzerland expert Stephen Halbert wrote in a 1999 Wall St. Journal editorial. “If there is a Schuetzenfest in town, you will find rifles slung on hat racks in restaurants, and you will encounter men and women, old and young, walking, biking and taking the tram with rifles over the shoulder, to and from the range.”

Mass shootings are rare across Europe. Here’s a rundown of major multiple-homicide gun crimes in Europe in since 1989.
