Reuters - A gas explosion shook a residential building in Iran�s capital Tehran on Saturday, injuring one person, the semi-official ISNA news agency quoted the city fire department as saying.

Several gas cylinders kept in a basement blew up, damaging the building and injuring a resident, a fire department spokesman told ISNA.

There have been several explosions around Iranian military, nuclear and industrial facilities since late June.
