GENEVA - Three people were injured by gunfire in central Zurich on Monday, police said, with local media reporting the incident occurred in a Muslim prayer hall near the city's railway station.

"I can only confirm that there was a shooting," a spokeswoman for Zurich police told AFP, adding a statement would be released later.

Swiss media said the three wounded people, all adults, were found in the street where the prayer hall is located. The suspected assailant had fled the scene and police sealed off the area, they said. Zurich police confirmed people had been hurt in an incident on Zurich's Eisgasse, but gave no more details. Police had sealed off the area. Some police were standing near the entrance of the building, where an Islamic centre and several businesses are registered. It was not immediately clear whether the Islamic centre or any of the other businesses were the target of the attack.

Across Switzerland, two thirds of 8.3 million residents identify as Christians. But the nation has been wrestling with the role of Islam as its Muslim population has risen to 5 percent with the arrival of immigrants from former Yugoslavia.

In 2009, a nationwide vote backed a constitutional ban on new minarets.

Three police vehicles and one ambulance were at the scene shortly before 7 p.m. (1750 GMT), while one ambulance had just driven away, a Reuters witness said. Roughly 20 police officers were present.
