Police say a landslide has buried a residential building near a city in southern Switzerland, leaving two people dead, four injured and an unknown number missing.

Police spokesman Marco Tutti said the landslide occurred early Sunday morning in Lugano when heavy rain caused a hill to collapse and cover the building with masses of mud.

Tutti said police and firefighters are on the scene searching for an unknown number of missing people.

The four injured people were taken to a nearby hospital.
