Two Turkish men have been injured in a shooting in central Zurich, according to Swiss police.
A gunman opened fire in a building in the Langstrasse area in the Swiss city at 15:00 local time (13:00 GMT), local media say.
Police say they are searching for a suspect who fled the scene. The motive for the shooting remains unclear.
They cordoned off the surrounding streets, according to the Tribune de Geneve.
The men, both Turkish nationals, are believed to be in stable conditions in hospital.
Police have evacuated four people from the building, according to Swiss media. The Langstrasse, a major route in the centre of the city, has now reopened to traffic.
Marco Cortesi, a spokesman for Zurich police, said: "At around 15:00, we received a phone call that there was a shooting here at Langstrasse.
"We sent our troops here and they've found two injured people, which have been sent to a hospital. The two are Turkish, middle-aged and I can confirm that they are out of mortal danger."
Reporters say the Langstrasse area is mixed - many immigrant communities live there and it is known as an area affected by the sex trade and crime.
