A gas line exploded Thursday in a Bay Area city, injuring at least six people and starting a major neighborhood fire.

A video provided by a neighbor showed a huge explosion that sent large debris flying into the air. Multiple homes on a residential street in Hayward, California, a city of about 163,000 people, were burning as of Thursday afternoon.

Approximately 75 fire and other emergency personnel were on scene trying to extinguish the blaze, said Ryan Nishimoto, deputy chief of operations for the Alameda County Fire Department. Aerial television footage from Thursday afternoon showed fire trucks spraying water on a car’s metal frame, as well as homes with burning roofs. At least one home appeared to have been destroyed.

It is unclear exactly what triggered the explosion.
