PASADENA, California (AP) -- Raw waste rushing through a city sewer line backed up into homes, blowing open toilet lids, filling bathtubs and damaging at least seven homes.

Waste began rushing into toilets and drains at about noon Saturday after city workers unblocked a clogged sewer line, city street supervisor Leo Alamillo said.

"It was like a volcano out of the commode," Mario Duenas told the Pasadena Star-News.
