OSLO, Norway (AP) — A tram derailed in downtown Oslo and crashed into an iPhone and computer store Tuesday, Norwegian police said, but the accident miraculously did not left four people slightly injured.

There were around 20 people on board the commuter train when it derailed at an intersection in Storgata, one of the Norwegian capital’s main thoroughfares.

Footage from the scene shows that most of the first car of the tram had crashed into the store.

The tram driver was among the injured. Police said everyone was treated at the scene, but no one was seriously injured.

The cause of the accident was not immediately determined and police said they were awaiting the arrival of members of the Norwegian Safety Investigation Authority. The four-story building was then protectively evacuated to check for structural damage.
