PHILADELPHIA (CBS/AP) — A high-rise building in one of Philadelphia’s most upscale neighborhood has been evacuated because of a strong odor that sent eight people to hospitals complaining of throat irritation.

The incident happened at the Rittenhouse Claridge Apartments at 18th and Walnut streets at about 9 a.m.
Fire officials say they haven’t yet identified the source of the odor but a hazmat team has declared the situation under control.

Executive Chief Richard Davison says it’s not clear how long it will be before residents can return to the building that faces Rittenhouse Square.

The American Red Cross of Southeastern Pennsylvania was providing mass care such as refreshments to evacuated residents.
