Doorbell footage has captured the moment a house in Hayward, California exploded. Six people were injured, including three who were seriously wounded.
The blast was caused by a natural gas line leak that firefighters had examined earlier in the day. They were called back after reports of an explosion and fire.
At least three buildings on two properties were “significantly damaged,” and a third property adjacent to the others was also damaged, according to the Alameda County Fire Department.
