Four stabbed by man shouting 'Allahu Akbar' during violent rampage at Swiss train station

A major police operation is underway after a man attacked several people with a knife at a major railway station in Switzerland.

Emergency services are in attendance at the Winterthur station after reports of a man running out of the train station concourse holding the weapon, shouting "Allahu Akbar."

It is not yet known if there have been any fatalities.

An eyewitness told local media: "I arrived at the train station around 8.20am. I was on my way to the ZHAW to study. About 30 meters away, I heard a man behind me shout 'Allahu Akbar' five or six times in a very emotional and agitated manner."

Another eyewitness said a teacher stood in front of a group of schoolchildren who were passing at the time of the stabbing to protect them.
