VIENNA (Reuters) - Four people were seriously injured and others were also hurt in a partial building collapse in Vienna on Wednesday, a spokesman for the city's ambulance service said.
The partial collapse of several floors of up to two buildings is thought to have been caused by a gas explosion, the police said earlier.
