Authorities say a gas leak could be to blame for a house explosion that injured at least one person in St. Paul, but the investigation into the blast continues.
The explosion happened about 8:30 a.m. local time Friday, sending flames and debris into the air. One person was pulled from the wreckage. Deputy St. Paul Fire Chief Dave Berger said the man in his 60s was conscious when he was taken to a local hospital, but his condition was unknown. A dog and a cat were also rescued from nearby homes.
