A train derailed early on Monday in southern Switzerland, police said, adding that people were likely to be injured as a result.

"Derailment of train, probably with injuries," regional police said in a post on the social media platform X, adding that the derailment occurred at 7:00 am (0600 GMT) in Goppenstein and more information would follow as it became available.

No more details on the incident were immediately available, the police said when asked by AFP.

The federal train operator CFF said on its website that train traffic "is interrupted between Goppenstein and Brig" because of an avalanche.
