Six injured in California house explosion

Doorbell video captured the moment a house exploded in Hayward, California. Six people were injured, three of them seriously.

The explosion was caused by a leak in a natural gas pipeline that firefighters had inspected earlier in the day. They were recalled following reports of explosions and fires.

According to the Alameda County Fire Department, at least three buildings on two properties were “significantly damaged,” and a third property adjacent to the others was also damaged.
