Investigators look at fridge as possible cause of warehouse fire in Oakland

A warehouse fire in California that killed 36 people does not appear to have been started intentionally and may have been caused by a refrigerator or other electrical appliance, investigators have said.

Details about a possible cause emerged as fire crews nearly completed their search for bodies in the most lethal building fire in the US in more than a decade. The death toll remained at 36 and is not expected to go higher.
